1. Executive Summary

1.1 On February 4, 2014, the Ministers of Natural Resources and Industry requested that the National Energy Board and Competition Bureau work together to review propane market issues. This final report builds upon the preliminary report released publicly on March 11, 2014, and provides a detailed analysis of the overall propane market in Canada.

1.2 In Canada, propane is produced, stored, transported, and distributed across a broad supply chain. Upstream firms produce propane through natural gas processing and crude oil refining. Propane is then either stored in underground storage caverns or transported by pipeline, rail, or truck by midstream firms. Finally, downstream distributors move propane to consumers, who purchase it for business and personal use. Propane supplies are also traded with the U.S.

1.3 During the winter of 2013-2014, initial propane inventories were lower than average and demand was unexpectedly high in Canada and the U.S. Supply tightened, prices increased rapidly, and there were local reports, especially in Ontario and western Quebec, of retail delivery problems. Factors contributing to this were:

  • A colder-than-normal winter across the eastern parts of Canada and the U.S. that resulted in greatly increased demand for home or “space” heating fuels;
  • An exceptionally large and wet corn harvest in the U.S. Midwest, resulting in greater-than-normal demand for propane to dry the corn prior to storage;
  • Supply chain congestion and disruptions due to weather and maintenance, resulting in less propane being available for distribution and delivery; and
  • Rapidly growing U.S. exports of propane to overseas markets, reallocating volumes which might otherwise be available in Canada and the U.S.

1.4 Tight supply continued for most of the winter, but prices came down considerably after peaking in late January, and local delivery problems eased. Redirection of supply from the U.S. Gulf Coast to the U.S. Midwest helped moderate prices in both Canada and the U.S. Propane consumers, including households, were significantly impacted by these price fluctuations, but an independent examination conducted by the Competition Bureau did not uncover sufficient evidence, based on the information collected, to conclude that anti-competitive behaviour exacerbated the impact of high prices on consumers. Should the Bureau become aware of behaviour that contravenes the Competition Act, it will not hesitate to take the appropriate action.

1.5 An examination of the factors that could contribute to future propane shortages and price increases indicates that there is no overall supply-demand imbalance in the propane industry that will create ongoing shocks or prevent the market from correcting future shocks. However, propane demand and prices are historically volatile and unforeseen events such as those that occurred this winter will likely continue to cause volatility.

2. Introduction

2.1 The National Energy Board (NEB) and Competition Bureau (Bureau) were asked to work together to review propane market issues, including price increases, scarcity, and the volume of propane exports to the U.S. More specifically, in a letter dated February 4, 2014,[1] the Ministers of Natural Resources and Industry requested that the NEB and Bureau examine:

  • the propane supply and demand situation in Canada, including production, inventories, exports/imports and end-use;
  • the propane distribution network;
  • wholesale and retail propane pricing;
  • composition of the wholesale and retail market;
  • the factors that have contributed to the recent shortages and price spikes;
  • whether there have been any anti-competitive activities that may have exacerbated the impact on consumers; and
  • any potential factors that could exacerbate the current market challenges or contribute to future propane shortages and related price increases.

 2.2 The NEB and the Bureau prepared a preliminary report analyzing the above issues, with emphasis on the availability of current supplies and initial perspectives on the factors that may have led to recent propane shortages and price increases in Canada. The preliminary report was released publicly on March 11, 2014.[2]

2.3 This more detailed final report updates and builds upon the findings of the preliminary report and adds new analysis in areas such as potential anti-competitive activities and factors that could contribute to future propane shortages and related price increases.

2.4 The NEB and the Bureau are well-equipped to undertake this market review. As Canada’s energy regulator, the NEB has a significant understanding of, and experience with, the Canadian propane industry.[3] The Bureau has substantial expertise in assessing the performance of various industries and examining the role that competitive forces play in market outcomes.[4] The two organizations worked together on the preliminary and final reports, with the exception of Section 7 of this final report, which describes an independent examination conducted by the Bureau.

2.5 In drafting this report, the NEB and the Bureau examined proprietary and publicly available information from across Canada and the U.S. Canadian data was collected from the NEB, Statistics Canada, Kent Marketing Services, Natural Resources Canada, and Environment Canada. There is limited information on propane demand in Canada, but production data is compiled by the Alberta Energy Regulator, the Saskatchewan Ministry of the Economy, and the B.C. Ministry of Energy and Mines.

2.6 U.S. data and information was collected from the Energy Information Association (EIA) and the National Oceanic and Atmospheric Administration (NOAA). Hub pricing data was collected from Bloomberg, Butane-Propane News, and

2.7 These Canadian and U.S. sources, combined with reports from various media outlets, consultants, and industry publications, paint a relatively detailed image of the propane industry. However, limitations exist within the data (see Appendix).

2.8 As a result, this data-based research was supplemented by consultations with a range of stakeholders from all parts of the propane supply chain. Interviews with sixty-eight market participants have been completed, including twelve firms performing upstream and/or midstream activities, forty-one firms performing downstream activities, and fifteen industry associations, consumer groups, and other stakeholders.

3. The Canadian Propane Industry

3.1 Propane is a natural gas liquid[5] (NGL) that is relied on by Canadians for a variety of purposes, from home heating and cooking to agricultural crop drying and fueling vehicles. In 2012, approximately 10.2 million cubic metres of propane were consumed in Canada.[6] Table 3.1 reports the most common end uses of propane in Canada. Figure 3.1 shows the percentage of propane consumed by sector during 2012, with residential uses, including home heating, accounting for 9 per cent.

In residential use, propane is used for home heating, water heating, and cooking. In commercial use, propane is used for space heating, water heating, and cooking. In industrial use, propane is used as a fuel for forklifts and as a heating source for refining activities. In transportation, propane is used as an automotive fuel. In agriculture, propane is used for crop drying, and barn and stable heating. In non-energy uses, propane is used by the petrochemical industry for manufacturing plastics.

This pie graph illustrates the consumption of propane by sector in Canada as a percentage of total propane consumed. Industrial is the largest consumer at 39 per cent, followed by non-energy use at 22 per cent. Commercial and residential use of propane account for 20 and 9 per cent respectively. Lastly, transportation consumes six per cent and agriculture consumes 4 per cent.

3.2 Propane is a common source of heating fuel for residences and businesses that are not served by natural gas pipelines. Statistics Canada estimates that approximately one per cent of Canadian households heat with propane,[8] with the highest rate in Ontario at two per cent.[9] Figure 3.2 shows the geographic distribution of residential demand for propane, which is concentrated in Ontario.

This area graph illustrates residential consumption of propane by province or region in Canada from 2005 to 2012. Ontario is the largest consumer of propane, accounting for more than half of all propane consumed by the residential sector in Canada. Alberta is the second largest, followed by Atlantic Canada, Quebec and B.C. Saskatchewan, Manitoba and the territories consumed the smallest amounts. Propane demand by the residential sector in Canada has been steadily increasing over time, from 482 thousand cubic metres in 2005 to 734 thousand cubic metres in 2012.

3.3 Propane is produced through two means. Approximately 85 to 90 per cent of Canadian propane is produced as a result of natural gas processing, and the remaining 10 to 15 per cent is produced as a by-product of crude oil refining. In 2013, approximately 11 million cubic metres of propane were produced in Canada.[10]

3.4 Propane for resale is universally processed to an industry standard called “HD-5.”[11] Once propane has been processed to this standard, there is no meaningful chemical difference between the propane sold by one firm and another.

The Canadian Propane Supply Chain

3.5 Participants in the Canadian propane industry operate in a supply chain (see Figure 3.3) that can be separated into three categories:

  • Upstream producers separate propane from natural gas through gas plant processing and fractionation,[12] or produce it as a by-product of crude oil refining;
  • Midstream firms store large quantities of bulk propane in salt caverns and/or transport propane long distances via pipeline, rail, or truck from the areas where it is produced to where it is consumed; and
  • Downstream distributors deliver propane to end users.

3.6 Initial observations indicate that each level in the supply chain is generally served by a separate group of firms, with no single entity responsible for every function of the supply chain. Although some firms may be present at more than one level, this appears to be the exception and not the norm.

Propane is produced from natural gas or oil, both of which come from wells. Natural gas is transported by pipeline to a field gas plant or straddle plant, where natural gas liquids are then transported by an NGL pipeline to a fractionator. Once the propane has been separated from the stream of NGL by the fractionator, it is transported by a propane pipeline or a rail line, either to underground storage caverns in Canada, or to the U.S. for export. Unrefined oil is transported by oil pipelines and rail to a refinery, where the propane is separated from other petroleum products. Once it has been separated, propane is either used for that refinery’s own use, or is transported by pipeline or rail line to underground storage caverns in Canada. Propane can also be imported from the U.S. via propane pipeline and rail lines for storage in underground storage caverns. Underground storage caverns in Canada have capacity ranging from 4,000 to 600,000 cubic metres per facility. Propane is extracted from underground storage caverns to propane terminals, and shipped by transport truck or rail car to propane retailers. Each propane transport truck has a capacity of between 38 and 62 cubic metres, and each rail car has a capacity of 120 cubic metres. At a propane retailer’s location, propane can be stored in large storage tanks with a capacity of approximately 20 to 200 cubic metres per retailer. Retailers then use bobtails and tank wagons, which have a capacity of between 10 and 20 cubic metres per truck, to deliver propane to end customers. The activities involving extraction and processing of propane are typically referred to as “upstream” activities, whereas storage and transportation are considered “midstream”, and end delivery is “downstream”.

Upstream Production of Propane

3.7 Canadian propane production is centred in western Canada. As described above, approximately 85 to 90 per cent of Canadian propane is produced from natural gas processing. Of that amount, approximately 88 per cent is produced in Alberta due to the large amount of natural gas development in that province. British Columbia is the second largest gas plant producer of propane and is responsible for seven per cent of the Canadian total. Small volumes are also produced from gas plants in Saskatchewan and from offshore gas fields in Nova Scotia.[13] The 10 to 15 per cent of Canadian propane production that comes as a byproduct of crude oil refining and upgrading is distributed more evenly across Canada.

3.8 There are a number of upstream propane producers in Canada but the majority of Canadian fractionation capacity is owned and operated by a few firms. Other producers of propane include firms that own and operate oil refineries and bitumen upgraders.

3.9 An upstream firm has three options to dispose of propane once it has been produced:

  • immediately sell the propane locally to downstream firms or third parties;
  • move bulk quantities of propane along midstream transportation assets (i.e., pipeline, rail, or truck) to downstream firms located elsewhere; or
  • store the propane for later use or sale.

3.10 Volumes produced by upstream firms are generally sold to large midstream or downstream customers. These sales are typically made according to annually-negotiated contracts that specify target volumes and pricing mechanisms.[14]

3.11 When negotiating purchase contracts, upstream suppliers typically require that midstream and downstream customers buy at least one barrel during the low demand summer months for every three barrels that they require during the high demand winter season.[15]

Midstream Storage of Propane

3.12 Propane demand is highly seasonal and variable, with peaks occurring in the fall and winter due to crop drying and heating fuel end use. Propane storage enables firms to amass inventories of propane over the course of the year to meet peak-season demand and to mitigate price volatility.

3.13 Underground salt caverns are the preferred storage option for large volumes of propane, as they can safely hold bulk quantities at a relatively low cost compared to above-ground options. Salt caverns are also easier to use than other underground options such as depleted oil and gas reservoirs or aquifers.[16]

3.14 Underground storage caverns are developed in locations with underground salt formations that are in the vicinity of, or connected by pipeline, to NGL fractionators, truck and rail terminals, or major NGL consumers such as petrochemical facilities or refineries. In Canada, underground storage caverns are located in Alberta (Fort Saskatchewan, Edmonton, and Redwater), Saskatchewan (Kerrobert, Regina, and Richardson), and Ontario (Windsor and Sarnia).[17] The total underground storage capacity for propane in Canada is estimated at 2.6 million cubic meters.[18] Over the last five years, the actual capacity used has fluctuated between 6 per cent and 65 per cent of this total depending on seasonality and other demand variables.[19]

3.15 In order to move propane into a storage cavern, salt water (brine) is pumped out while propane is injected into the top of the cavern. Propane and other hydrocarbons have a lower density than brine and therefore float on top of the brine in the cavern. To remove propane from the cavern, brine is injected into the cavern while propane is pumped out.[20] The salt walls of the cavern are insoluble to hydrocarbons, which prevents leakage.

3.16 Underground storage caverns are owned by upstream and midstream firms, and storage space in these caverns is generally leased by certain downstream distributors to store their supplies until they are needed, at which point they are withdrawn from caverns for further transport. Underground storage space is typically leased according to yearly or multi-year contracts that specify volumes and prices.

Midstream Transportation of Propane

3.17 The two most common means for transporting propane long distances from storage facilities or producers to downstream distributors are pipeline and rail. Transporting long distances via truck is often uneconomic.[21]

3.18 Currently, one major pipeline system supplies propane from western Canada to central Canada: the Enbridge System.[22] The system is primarily used to transport crude oil, but two of its lines also transport refined petroleum products and a propane-plus mix[23] from Fort Saskatchewan, Alberta to Sarnia, Ontario, where the mix is fractionated into propane, butane and condensate:

  • Line 1 has a capacity of 37,600 cubic meters per day (236,500 barrels per day) and runs from Fort Saskatchewan to Superior, Wisconsin. It transports batches[24] of natural gas liquids, refined petroleum products, and light synthetic crude oil.
  • Line 5 has a capacity of 78,100 cubic metres per day (491,200 barrels per day) and runs from Superior to Sarnia. It transports batches of natural gas liquids, as well as various types of crude oil.

3.19 From 2006 to March 2014, another pipeline system also supplied propane from western Canada to central Canada.[25] Kinder Morgan’s Cochin pipeline had a 7,950 cubic metres per day (50,000 barrels per day) operating capacity and delivered propane from western Canada primarily to markets in the U.S. Midwest. Cochin also delivered small volumes of propane to Windsor, Ontario and later to Sarnia via the Eastern Delivery System pipeline (see Figure 3.4). The capacity and utilization of the Cochin pipeline was significantly less than that of the Enbridge System and the vast majority of NGL (including propane) supplied to central Canada via pipeline was through the Enbridge System.

3.20 Historically, the Cochin pipeline operated below capacity. Given declining propane production and exports from western Canada, and growing demand for condensate in the oil sands, Kinder Morgan applied to the NEB in 2012 for approval to reverse the section of pipeline west of Kankakee County, Illinois to allow for condensate imports into Alberta. The NEB approved this application in June 2013, with conditions.[26] The Cochin pipeline stopped receiving propane at the end of March 2014 and Kinder Morgan is undertaking the physical work associated with the reversal.

3.21 The Cochin Reversal Project also required approval in the U.S. It received a presidential permit from the U.S. State Department to proceed with the project in November 2013.[27]

3.22 In order for propane to be moved by rail, rail car filling and unloading infrastructure (commonly called “racks” or “terminals”) is constructed at both the origin and the destination. Facilities located at an originating production plant are generally owned by upstream firms, while facilities at the destination are generally owned by a downstream firm.

3.23 Rail transit of propane can encounter significant disruptions during winter months. Frozen signals can delay progress and cause congestion. Cold weather can also cause train engine issues, and significant snowfalls can cause delays while tracks are cleared. Additionally, it has been reported that one significant rail line experiences air pressure issues when the weather is cold and, as a result, is forced to run shorter trains.[28] This can result in a shortage of engines, which further reduces the effective capacity of rail.

3.24 During the winter peak home heating season, propane rail transportation may operate at, or near, full capacity. In this situation, if a shipment is not transported on its scheduled day, it can be cancelled if there is no extra capacity on the following day. When this happens, downstream firms may not obtain their contracted or planned supply.

Downstream Distribution of Propane

3.25 Downstream distributors generally purchase supplies from terminals directly, by sending trains or trucks to those locations,[29] or indirectly, by drawing supplies from another downstream firm’s storage facilities or using third-party shipping.

3.26 Large downstream distributors typically have storage facilities of their own in the form of above-ground “tank farms” containing large propane storage tanks from which delivery trucks (or “tank wagons”) are filled.

3.27 Smaller firms, particularly those located near a terminal or near a large distributor, may choose to run trucks to the terminal or distributor on a daily basis rather than invest in storage facilities. Downstream firms with a small customer base typically do not own storage assets. This reliance on trucking, especially in the case of smaller firms without storage assets, makes downstream distribution particularly susceptible to logistical challenges during cold weather. Snow can block or slow access roads to terminals, tank farms, and end-users (including homeowners).

3.28 Downstream distributors that have invested in storage facilities typically have sufficient storage capacity to fulfill one or two days’ worth of peak demand. Downstream distributors have reported that the limited benefits[30] of additional storage are outweighed by the financial and regulatory costs associated with storage expansion, especially for downstream distributors with only a small number of customers.[31]

3.29 Purchases by downstream distributors are typically made according to annually-negotiated contracts that specify target volumes and pricing mechanisms. Under these contracts, downstream distributors typically pay a “floating”, variable price upon receipt of their propane supplies (the “rack rate”) and few, if any, are on fixed price contracts. When wholesale prices fluctuate, these changes are reflected in the retail prices paid by end consumers. Most downstream customers pay a retail price at the time of tank filling, with few negotiating fixed price contracts in advance.[32]

Household Consumer Demand

3.30 Contractual terms for end-use consumers on floating price contracts vary by retailer, but most allow for immediate customer exit subject to certain costs discussed below. For customers on fixed price contracts, retailers pre-buy equivalent volumes from their suppliers immediately upon entering the contract. Pre-buying in this manner comes at a premium to account for storage costs. This premium is passed on to consumers, which may account in part for limited consumer interest in such contracts.

3.31 Downstream distributors report that they supply propane storage tanks to customers on a rental basis, with a small proportion of customers opting to purchase their own tanks. Once a retailer has placed a rental tank at a customer’s site, no other supplier can fill the tank due to contractual restrictions. If a customer wishes to switch its supplier, downstream distributors often charge fees for tank installation, tank removal, or both. While these fees vary across distributors and depend on the nature of the customer-supplier relationship, they represent a deterrent to customer switching.[33]

3.32 Once a consumer chooses to use propane, significant investments must be made to acquire equipment and appliances that are specifically designed to use propane only.[34] As a result, these consumers cannot easily switch to other fuels, and it is therefore likely that residential demand for propane is inelastic in the short term.[35]

3.33 Given this inelastic demand, and the significant costs associated with switching from propane to another fuel, consumers have limited options when prices rise.[36] Households that rely on propane will either consume the same volume of propane and pay substantially more for it, or reduce their consumption in order to partially offset the higher prices. As a result, many Canadians have been significantly impacted by the recent price increases and supply challenges.

The Integrated Canada-U.S. Propane Industry

3.34 The Canadian propane industry is integrated with its counterpart in the U.S. Canada produces more propane than it consumes and exports this surplus to the U.S., its only export market. Canada also imports small volumes of propane (equivalent to less than five per cent of Canadian propane exports) from the U.S. into Ontario, eastern Canada, and British Columbia.[37] Terminal facilities do not exist in Canada that allow for propane exports to, or propane imports from, overseas markets.[38]

3.35 The primary U.S. regional markets for Canadian propane exports are the Midwest and East Coast. In 2013, approximately 85 per cent of Canadian propane exports were to these two regions. Canadian propane is exported to the U.S. primarily by rail (55 per cent) and pipeline (35 per cent), with trucking accounting for the remainder (10 per cent).[39]

3.36 Major propane hubs in Canada include Edmonton, Alberta and Sarnia, Ontario. In the U.S., the two largest hubs are Mont Belvieu, Texas and Conway, Kansas. Figure 3.4 shows these four hubs along with major Canadian and U.S. pipeline infrastructure for natural gas liquids (including propane). Figure 3.5 shows that posted wholesale prices at these hubs tend to track each other, a further indication of the integrated nature of the Canada-U.S. industries.

This is a map of North America showing major natural gas liquids pipelines in Canada and the U.S. as of 2013. It shows two pipelines operating from western Canada to eastern Canada: the Enbridge pipeline system and Kinder Morgan’s Cochin pipeline. Both of these pipelines flow from north of Edmonton, Alberta to Sarnia, Ontario. There are also a large number of pipelines in the U.S., with primary hubs located in Conway, Kansas and Mont Belvieu, Texas.

This graph illustrates wholesale propane prices at North American hubs as measured in cents per litre. The four hubs displayed are Edmonton, Alberta; Sarnia, Ontario; Mont Belvieu, Texas; and Conway, Kansas. The prices have generally followed each other closely, with prices at Edmonton generally lower than the other hubs. Wholesale prices have generally risen and fallen together during past price spikes, as observed in 2000-2001, 2002-2003, and 2009-2010. In 2014, monthly average wholesale prices reached new highs between 60 and 70 cents per litre at each hub.

How Canadian Propane Prices are Determined

3.37 Retail propane purchases are private transactions involving a downstream distributor and an individual family or business. No centralized data source measures and collects these prices. However, propane prices for automotive uses are reported by Natural Resources Canada,[40] and are a potential proxy for the market-set prices for home consumption and other propane end uses.[41] Figure 3.6 shows automotive propane retail prices in conjunction with posted Canadian wholesale prices from January 2000 to March 2014, and illustrates their correlation.

Text Version

This graph illustrates monthly average hub prices in cents per litre at Edmonton and Sarnia with the Canadian average automobile propane price, including taxes. The graph suggests a strong correlation between retail propane prices and wholesale propane prices. In response to wholesale propane prices rising to new highs in early 2014, the Canadian average for automobile propane prices also increased to a new high of 106 cents per litre. Following the price spike, wholesale prices have declined as have automobile propane prices, which are under 100 cents per litre as of April 2014.

3.38 Wholesale contracts are generally negotiated on an annual basis between upstream producers of propane and their midstream and downstream customers using posted prices as references. In these negotiations, buyers and upstream sellers generally do not lock in fixed prices, but negotiate discounts from, or premiums to, posted wholesale prices. Wholesale prices (both actual and posted) are the result of market forces.

3.39 When wholesale prices rise or fall (which increases or decreases producers’ margins), midstream and downstream firms generally pass on this change, at least partially, to end-use consumers. Market participants have indicated that midstream and downstream distributors focus on achieving a certain cents-per-litre margin on propane, rather than attempting to earn a particular percentage margin.[42] Fixed price contracts, in which consumers pay a premium for price certainty, are uncommon for household uses.

Regulation of Propane

3.40 The propane industry is subject to various federal, provincial, and municipal regulations, including general business and environmental regulations applicable to many industries. Two areas of Canadian propane regulation particularly relevant for this report are retail prices and exports.[43]

3.41 Retail propane prices are regulated to varying degrees in five Canadian provinces by the following authorities:

  • Prince Edward Island Regulatory and Appeals Commission;
  • Newfoundland and Labrador Board of Commissioners of Public Utilities;
  • New Brunswick Energy and Utilities Board;
  • Public Utilities Board of Manitoba; and
  • British Columbia UtilitiesCommission.

3.42 The manner in which retail propane prices are regulated varies from province to province,[44] as does the application of the regulated price (e.g., whether regulation applies to all propane, only propane for space heating, only propane delivered through the pipeline grid, etc.). These regulations are made pursuant to specific provincial legislation and only apply to propane prices within a given province. Unregulated retail prices in these and other provinces are determined by the market.

3.43 Canadian propane exports are regulated by the NEB and governed by the National Energy Board Act (NEB Act) and related regulations.[45] All propane exports must be authorized by a licence or order, and must be reported to the NEB on a monthly basis.[46]

3.44 In the case of propane export licences, the Board must satisfy itself that the propane to be exported is surplus to Canadian needs.[47] A propane export licence requires Governor in Council (i.e. federal Cabinet) approval, and cannot exceed 25 years. The Board has discretion to include terms and conditions in the license on subject matters set out in the NEB Act and its regulations.[48]

3.45 Propane export orders are not subject to the “surplus test” applicable to export licenses and do not require Governor in Council approval. Propane export orders cannot exceed one year[49] and contain different terms and conditions than those applicable to export licenses.[50] Export order applications normally require minimal information and are processed in two working days by the NEB. Export licence applications have more detailed information requirements[51] and entail significantly more assessment time. Holders of both licenses and orders are required to report certain information to the NEB, including monthly export volumes and revenues.

3.46 In recent decades, the propane industry has exported propane by means of short-term orders rather than long-term licences. No propane licenses are currently in effect. Between 64 and 72 export orders have been issued in each of the last five years.

3.47 The NEB’s current propane export regime reflects a broader policy trend, initiated in 1985[52] and reinforced in later years through trade agreements and other measures, toward a more flexible and market-oriented regulatory framework for the energy industry. The NEB affirmed this policy direction in a 2002 decision on Atlantic Canadian export order procedures for natural gas: “The Board believes that the public interest is best served by allowing markets to work unless there is clear evidence of significant market dysfunction.”[53] In that decision, the Board decided against implementing “procedures that would unduly interfere with the normal operation of the market.”

4. Current Situation


4.1 At the time of this report, propane prices had fallen substantially from the highs reached in January and February 2014. This is illustrated in Figure 4.1, which shows propane prices at major Canadian and U.S. hubs this winter.[54] The price increases at the Canadian hubs were not as dramatic as the price spike at the Conway hub, which is the most closely linked to the large U.S. Midwest residential propane market.

Text Version

This graph illustrates the daily average spot price of propane at the hubs of Edmonton, Sarnia, Mont Belvieu and Conway from October 2013 to April 2014. The graph shows the gradual rise in propane prices in October and November and larger increases particularly in December and January. The price spikes that occurred at Conway in late January are outliers, where spot propane traded at 140 cents per litre or nearly 5 dollars per gallon, while other hubs remained below 80 cents per litre. Prices have since declined across North American hubs to around 30 to 35 cents per litre, except Sarnia which is around 40 cents per litre.

4.2 Figure 3.5 and Figure 3.6 illustrate both the size of the price increases this winter and the historic volatility of propane prices more generally. Although this winter’s price increases were notable for the pace at which they occurred and for breaking nominal price records, they are comparable, in terms of percentage increase, to other rapid propane price spikes that have occurred in Canada since 2000, as shown in Table 4.1.

4.3 Canadian gas plant production of propane peaked in 2000, and propane production had been on a steady decline until recent years. Since 2011, higher prices for natural gas liquids relative to the price of natural gas have encouraged the development of more liquids-rich natural gas in western Canada, resulting in a nine per cent increase in gas plant propane production between 2010 and 2013. Figure 4.2 shows annual natural gas and propane production from gas plants, which account for 85 to 90 per cent of total Canadian production. Long-term propane production decreases are correlated with declining natural gas production in Canada.

This graph plots annual Canadian natural gas production with annual propane production from natural gas processing plants and illustrates some correlation between the two. Natural gas production in Canada has steadily declined in recent years, from 171 billion cubic metres in 2000 to 145 billion cubic metres in 2013. Similarly, propane production has declined from 11 million cubic metres to 9.4 million cubic metres over the same time frame. However, propane production has increased slightly since 2010 when 8.7 million cubic metres was produced.

4.4 Because propane is produced as a by-product of natural gas extraction and crude oil refining, production of propane cannot be expanded without also expanding the production of either natural gas or refined petroleum products - extensive processes that require significant time and resources, and which cannot be achieved in the short term.

Inventories and Supply

4.5 Interviews with Canadian industry participants indicate that downstream distributors, and ultimately consumers, had mixed success in acquiring sufficient supplies of propane to meet their needs this winter. Most distributors were subject to delays of varying lengths in accessing propane supplies, and some were put on “allotment”, whereby they could not access the full quantity of propane that they had contracted for. In certain cases, downstream suppliers were denied supply on a temporary basis, and this led to shortages of supplies for consumers. These problems seem to have manifested themselves more severely in eastern Ontario and western Quebec than in other areas of Canada, as reflected in reports of local delivery problems in these regions during December and January.

4.6 Industry interviews also indicated that small-scale propane retailers, particularly those with only one source of supply and no formal supply contract in place, sometimes had to provide less propane than the amount desired by consumers. Rationing of this nature was reported by smaller suppliers in greater proportion compared to larger, more established retailers with diverse supply contracts in place. These shortages were felt most severely in late December and early January, with downstream distributors generally indicating that these restrictions were eliminated by late January. Full service resumed shortly thereafter, once missed deliveries had been made.

4.7 More generally, Table 4.2 displays historical inventory levels and heating season withdrawals in eastern Canada and western Canada, while Table 4.3 shows the same information for the U.S. Midwest and Gulf Coast. The Midwest is a primary export market for Canadian propane, and is also the U.S. region that relies most heavily on propane for home and space heating needs. Additionally, wholesale prices at Midwest storage and trading hubs, such as Conway, Kansas, are linked with hubs in Canada. The U.S. Gulf Coast is the center of the petrochemical and refining industry in the U.S. and is also where the vast majority of propane is exported to overseas markets.

4.8 Table 4.2 and Table 4.3 also illustrate the effect of seasonal temperatures on propane inventories. For example, the 2011-2012 winter was notable for being one of the warmest on record for parts of Canada and the U.S., and the withdrawal of propane from underground inventories in most regions was close to half the size of the withdrawals observed during winters with more “normal” seasonal temperatures, such as the winters of 2010-2011 and 2012-2013.

This table lists underground inventories of propane in the U.S. Midwest and Gulf Coast at the start and end of the heating season from 2008 to 2014. This table also displays a five-year average at the start and end of the heating season, and a five-year average of the heating season withdrawal of propane in inventory.

4.9 As displayed in Figure 4.3, Canadian underground propane inventories from the start of the 2013 injection season on March 1 until the end of the season on September 31 were considerably below the five-year range. Unseasonably cold weather in March 2013 resulted in inventories declining in Canada at a time when storage usually builds. Furthermore, colder weather continuing into April resulted in storage building at a much slower pace than anticipated. Over the summer, Canadian inventories managed to build at a rate where inventories as of October 1, 2013 were just within the five-year range. Canadian inventories have remained below or at the bottom of the five-year range since.

4.10 U.S. Midwest underground propane inventories displayed a similar pattern as shown in Figure 4.4, but despite the large inventory draw observed due to the late end of the heating season, inventories remained within the five-year range through most of 2013. The effect of 2013’s large and wet corn harvest on inventories is noticeable in November, when inventories sharply dropped below the five-year range, and inventories have remained low since then.

This graph illustrates trends from 2008 to 2012 and recent data for Canadian underground propane inventories. The volume of propane in Canadian underground caverns generally peaks in October and bottoms in March or April. For much of 2013 and 2014, Canadian inventories remained at or below the five-year average range. The latest observation for April 2014 is below the five-year average range, but slightly above April 2013 levels.

This graph illustrates trends from 2008 to 2012 and recent data for underground propane inventories in the U.S. Midwest. The volume of propane in Midwest underground caverns generally peaks in October and bottoms in March or April. For much of 2013, Midwest inventories remained at the low end of the five-year average range. A sharp decline is seen in Midwest inventories in November resulting in a large storage deficit from the five-year average. Heading into 2014, inventories remained below the five-year range. The data for March and April have inventories remaining below, but closer to, the five-year range, and flattening out heading into the summer injection season.

4.11 In early 2014, large storage draws continued in Canada and the U.S. Midwest, primarily due to colder-than-average weather. Recent data, including that shown in Table 4.3, suggest that the low inventory situation in the U.S. Midwest was mitigated by propane from the U.S. Gulf Coast flowing northward to markets. The Gulf Coast withdrawal this winter was nearly double the five-year average and the largest since 2009-2010 due to both higher exports and increased volumes flowing northward.[55] As of early April 2014, U.S. Midwest inventories still remain low, but are closer to the five-year range.

4.12 This redirection of supply was achieved through market responses to price differentials (see Figure 4.1 and Figure 5.8) and policy responses at the U.S. state and federal levels. With regard to the latter, states of energy emergency were declared in more than 30 U.S. states. This led to the relaxation of trucking hours-of-service restrictions, which in turn facilitated increased propane deliveries from the U.S. Gulf Coast.

4.13 Furthermore, the Federal Energy Regulatory Commission (FERC) invoked its emergency authority for the first time[56] to help redirect propane supplies.[57] FERC issued an order that directed Enterprise TE Products Pipeline Company, LLC (TEPPCO) to temporarily provide priority treatment[58] to propane shipments on its pipelines from Mont Belvieu to the U.S. Midwest and Northeast from February 7, 2014 to February 14, 2014. During that week, shippers injected an additional 80 thousand cubic metres (500 thousand barrels) of propane into TEPPCO.[59] The FERC extended the order to February 21, 2014, which TEPPCO accepted.[60] 

4.14 Authorities in Canada did not pursue the mitigation measures that were used in the U.S. The relevant Canadian authorities have extended trucking hours in response to previous energy-related shortages,[61] but did not appear to do so in this instance. Also, though the NEB may have the authority to hold a short proceeding to consider, for example, what measures within its jurisdiction could be taken and be most effective, the NEB does not have broad emergency powers equivalent to those of the FERC. The NEB did not receive any requests this winter for emergency proceedings related to propane.[62]

Canadian Exports

4.15 Figure 4.5 shows annual propane exports from Canada to the U.S. from 2000 to 2013.[63] Exports have increased recently but have been declining over the long-term. Figure 4.6 compares monthly Canadian exports in 2013 and 2014 to a five-year range and average.

Annual Canadian propane exports to the U.S. have generally been declining from nearly 9,490 thousand cubic metres in 2000 to 5,817 thousand cubic metres in 2013. Annual Canadian propane exports to the U.S. have increased slightly from 2010.

This graph illustrates monthly Canadian propane exports to the U.S. Canadian exports exhibit a seasonal peak in December and January, and a seasonal trough through the spring and summer months. In October and November 2013, Canadian exports were slightly higher than the five-year average. Exports were at the bottom of the range in December 2013 and within the range since then.

4.16 In 2013, Canada exported 5.9 million cubic metres of propane to the U.S., which amounts to approximately 10 per cent of U.S. consumption. Exports in 2013 were approximately five per cent higher than in 2012, which is consistent with average annual growth since 2010, when exports from Canada to the U.S. were at their lowest recent level.

4.17 Table 4.4 shows monthly Canadian propane exports since 2008 and compares them to the five-year average for each month. Exports since September 2013 have fluctuated above and below the five-year averages. The only month with significantly above-average exports is October, which was due to shippers sending extra volumes in response to crop-drying demand and in anticipation of maintenance on the Cochin pipeline from November 27 to December 17, as discussed below. Even during January and February 2014, when prices in the U.S. Midwest were substantially higher than in Canada (see Figure 4.1), exports for these months were approximately 10 per cent lower than the corresponding figures for 2013.

5. Causes of Recent Propane Price Increases

5.1 Rapid propane price increases generally happen because of mismatches in supply and demand. Propane is produced at a relatively constant rate throughout the year due to its connection to natural gas processing and crude oil refining, and production cannot be quickly expanded or contracted in response to market events. However, since demand is highly seasonal, with large peaks in the fall and winter months, propane storage plays an important role. Even with storage, situations can arise where demand greatly exceeds supply due to one or both of the following:

  1. supply shocks, which may temporarily reduce the level of supply at one or more levels of the supply chain and place stress on the ability of the Canadian propane transportation and distribution system to deliver sufficient quantities; and
  2. demand shocks, which can cause greater-than-anticipated demand in a time period and place stress on distribution capacity.

5.2 Both demand and supply shocks occurred this winter, tightening supply at the same time that demand was very high. Propane inventories in the months preceding the fall and winter demand peaks were also below average, especially in the U.S. The result was increasing prices, logistical challenges, and limited supply for Canadians who rely on propane.

5.3 In years with less severe demand and/or supply shocks, demand in excess of contracted volumes can be covered by supplies from a spot market.[64] In situations with high sustained demand, however, few market participants have the ability to supply excess propane, and spot markets cannot effectively fulfill this role.

Increased Demand given Cold Weather

5.4 The winter of 2013-2014 has been colder than previous winters. Since a significant proportion of annual demand for propane occurs during winter (i.e., for home and space heating), the unusually cold weather created a demand shock. Retailers indicated in interviews that customer demand for home heating increased by 20 to 25 per cent compared to prior winters.

5.5 One way to measure how cold a winter has been in a geographic area is the number of “heating degree days”[65] experienced in that area. Figure 5.1 reports the number of heating degree days experienced during the past three winters across Canada, and shows that the winter of 2013-2014 was abnormally cold, whereas the two previous winters were relatively mild.[66]

Text Version

This graph illustrates a five-year range of heating degree days in Canada over the October to April heating season and data from the past three winters. Heating degree days are generally the highest in January, and begin to decline in February and March. Heating degree days in February and March were above the five-year range this year.

5.6 Firms throughout the Canadian propane supply chain indicated that, when choosing appropriate inventory levels for winter, they make forecasts based on their experience during the past three to five winters. The cold temperatures this winter were unexpected in these forecasts, and this contributed to propane inventories being drawn down more quickly than anticipated.[67]

5.7 Feedback from industry participants indicated that few industry players accurately predicted the tight supplies, increased demand, or price increases experienced this winter. Figure 5.2 presents propane price futures curves at the Conway price hub[68] at the end of each month from October to December 2013, and compares these curves to the actual prices experienced up to March 2014. In each case, the futures markets failed to predict this winter’s price increases.

This graph displays actual monthly average wholesale propane prices at the Conway, Kansas hub and displays futures price curves observed at the end of October, November and December in 2013. As prices continued to rise, each futures price curve indicated prices were not going to rise further. No curves were able to predict the price spike that would occur in January and February 2014.

5.8 As of November 30, 2013, weather forecasters were predicting a mild winter for the major propane-consuming areas of Canada. Figure 5.3 shows that a milder-than-normal winter was predicted (in yellow and orange) for southern Ontario, eastern Ontario, western Quebec, Nova Scotia, and eastern Newfoundland and Labrador - areas with higher-than-average reliance on propane for home heating during winter. Figure 5.4 shows a December 31, 2013 forecast which predicted a colder winter for most of Canada, but still did not foresee a colder-than-normal winter for these high demand areas (many of which are still in white).

As of November 30, 2013, Environment Canada’s seasonal forecast for the December 2013 to February 2014 time period indicated that Southern Ontario, Atlantic Canada, and the northern Territories were all expected to experience above normal temperatures with a probability of 40 per cent or greater. This same forecast predicted below normal temperatures across most of British Columbia, Alberta, and Northern Quebec.

As of December 31, 2013, Environment Canada’s seasonal forecast for the January to March 2014 time period indicated below normal temperatures across almost all of Canada. Only Southern Ontario and Atlantic Canada were expected to experience above normal or normal temperatures.

5.9 Major portions of the U.S. experienced a similarly cold winter. Figure 5.5 reports that the Midwest experienced weather that was “much below average”, while the northeast and north-central regions experienced a “below average” winter. In a year when Canada experiences cold weather and these states do not, it is possible that supplies could be reallocated to Canada. However, the uniform cold felt throughout the eastern portions of Canada and the U.S. this winter indicates that this was not likely possible.

Figure 5.5: December 2013-February 2014 Temperature Data for the U.S.

This map illustrates regional temperature ranks across U.S. regions for the time period of December 2013 to February 2014. Over this period, the U.S. upper Midwest experienced its 6th coldest winter on record. The lower Midwest experienced its 12th coldest winter on record. Below average winters for temperature were also encountered in the U.S. northeast, the northern Rockies, and the midcontinent and Gulf Coast regions.

5.10 The cold weather experienced across Canada and the U.S. also delayed and/or reduced the volume of propane shipped by train. As mentioned previously, at times of high demand for all propane-related assets, it can be difficult or impossible to make up for such shortcomings in the short run due to congestion issues and tight capacity utilization.

Increased Demand for Crop Drying

5.11 By some reports, 2013’s corn crop in the U.S. was 34 per cent larger than 2012’s.[69]  In addition, Figure 5.6 illustrates that much of the U.S. Midwest region, which grows a significant volume of corn, experienced a very wet autumn, with most Midwest states experiencing above normal precipitation between October and December 2013.

5.12 Prior to storage, corn must be dried to a moisture content of less than 15 per cent.[70] The size of the 2013 crop, the high moisture content of the harvest, and colder-than-average temperatures (thus requiring more propane to account for heat loss while drying) resulted in unusually high demand for propane in mid-October and November. Agricultural demand for propane in the U.S. during 2013 was estimated to be as much as five times greater than in 2012.[71] According to industry interviews, downstream distributors selling in Ontario and Quebec also saw an increase in agricultural demand in October and November.

5.13 Crop drying demand was so high that some Midwest states issued hours-of-service exemptions for commercial truck drivers delivering propane to meet high agricultural demand. Propane shortages and loading delays at terminals were reported in the Midwest starting in October 2013.[72] By November, the price for propane at the Conway hub had increased 50 per cent from June 2013 and 57 per cent from November 2012.

5.14 The corn harvest in 2013 also occurred later in the year than normal, resulting in the high crop drying demand overlapping with seasonal heating demand. This overlap provided less time for propane inventories to recover before the heating season.

This map illustrates statewide precipitation ranks in the U.S. from October to December 2013. Several states in the U.S. corn belt, such as Nebraska, Minnesota, Wisconsin, Michigan, Indiana, Ohio and the Dakotas experienced an autumn with “above normal” or “much above normal” precipitation.

Supply Chain Congestion and Disruptions

5.15 Congestion experienced at rack sites and other distribution points contributed to tight propane supply this winter. This congestion was likely the result of both greater-than-usual demands placed on propane terminals and other transportation infrastructure, and disruptions related to weather conditions.

5.16 Industry interviews indicated that during this winter’s periods of high demand, it was difficult to make up for even one missed delivery from a terminal to local storage, as terminal access was operating at or near capacity on an ongoing basis. In this respect, even if propane was physically present in the distribution terminal or storage cavern, supplies could only be made available at a maximum daily rate.

5.17 Rail infrastructure for propane distribution is limited in Ontario. As such, downstream distributors in Ontario generally use trucks to transport propane from terminals to their own tank farms. During this winter, truck transportation in Ontario was adversely affected by weather conditions.

5.18 In Quebec, a number of downstream distributors have developed rail infrastructure, which makes them vulnerable to rail congestion and supply disruptions caused by inclement weather. This winter, rail transportation of propane into Quebec was affected by weather conditions, and consequently some volumes of propane had to be trucked in, rather than railed in, to local distributors. This situation put additional pressure on trucking infrastructure.

5.19 Road closures also made it difficult for downstream distributors to deliver propane to end-users. Most home-heating propane customers are located in rural areas, and road closures can have a significant impact on timely deliveries to homes. Even as roads are eventually cleared, customers may face additional delays as trucks are used at capacity to make up for missed deliveries.

5.20 Additionally, the Cochin pipeline, used to transport propane to the U.S. Midwest and eastern Canada, was shut down for maintenance during a portion of November and December. In January 2013, Kinder Morgan informed Cochin shippers of rolling outages for maintenance that would be performed on the line, with maintenance progressing from east to west throughout 2013.

5.21 Maintenance on western sections of the Cochin pipeline was initially planned for four weeks starting mid-November. However, high crop-drying demand in October and November resulted in this being postponed until November 27, 2013.[73] When the maintenance did occur, work on two line segments was performed simultaneously, thus reducing the outage period from a planned four weeks to three weeks. Cochin returned to full service on December 18, 2013.

5.22 During the maintenance period, the line was shut down and no deliveries of propane were made to terminals in the U.S. Midwest and Ontario. Shippers increased injections of propane into the Cochin pipeline prior to the shutdown, resulting in higher Canadian exports during October (see Figure 4.6). Because the majority of shipments on the Cochin pipeline are to the U.S. Midwest, with only a small portion flowing to Ontario, any impact that Cochin’s maintenance may have had on propane availability would have been greater on the U.S. Midwest than on central Canada.

5.23 Finally, several upstream production facilities experienced temporary disruptions during this winter. Although production levels during the winter months constitute a reasonably small proportion of overall supply during the winter months, these disruptions created additional pressure on supply infrastructure, particularly in regions of Canada that do not rely on bulk underground storage caverns.

Decreased Availability due to Increased U.S. Exports

5.24 As U.S. propane production has grown in recent years, investments in export infrastructure at major U.S. terminals near Houston, Texas have increased the ability of upstream producers and midstream transporters to participate in overseas markets. Figure 5.7 illustrates the increase in U.S. propane production since 2005. Figure 5.8 shows that the prices U.S. propane exporters can obtain overseas have compared favourably to domestic prices, especially during 2012.[74]

5.26 Thus, even though U.S. production has increased significantly in recent years, the simultaneous increase in the percentage of U.S. production exported overseas has likely affected the availability of propane for end-users in Canada and the U.S. When combined with low inventories and very high demand, these U.S. exports likely impacted the ability of the Canadian and U.S. propane industry to adjust quickly during the winter of 2013-2014.

5.27 At the same time, Figure 5.8 shows that the price premium in European markets over Mont Belvieu narrowed during 2013 and that these prices were essentially the same by February 2014. Six U.S. Gulf Coast export cargoes equaling 475 thousand cubic metres (3 million barrels) of propane and butane were reported cancelled in February 2014 as overseas prices became less attractive.[76] Figure 5.9 also shows some curtailing of exports from the U.S. Gulf Coast in January and February of 2014.

6. Future Propane Supply, Demand, and Exports

Canadian Situation

6.1 In the 2013 edition of Canada’s Energy Future,[77] the NEB forecasts declining Canadian propane production in the short term as conventional natural gas production declines. Propane production is forecast to stabilize by 2020, before increasing after 2025 as production of unconventional shale and tight gas compensates for the decline in conventional gas production. Propane production from oil sands off-gas is also forecast to increase. These supply trends are illustrated in Figure 6.1.

6.2 A gradual increase in propane demand growth is also illustrated in Figure 6.1. Growth in the commercial, industrial, and agricultural sectors, as well as general population growth, are the primary drivers behind the NEB’s forecast of increasing propane demand in Canada. This combination of increasing demand and lower supply is forecast to result in declining volumes of propane available for export in the long term.

This graph illustrates the NEB’s long-term forecast for propane supply and demand from its 2013 report titled “Canada’s Energy Future”. Propane supply is expected to gradually decline through to 2020 when it will then steadily increase due to higher gas plant production of propane. Meanwhile, demand is expected to increase steadily through to 2035.

6.3 With regard to transportation, the Cochin pipeline reversal is not projected to have a significant long-term impact on Canadian supply and demand given its historically low utilization rates. As mentioned previously, the vast majority of NGL (including propane) supplied to central Canada via pipeline was through the Enbridge System even before Cochin started its reversal work. More generally, capacity was available on both Cochin and the Enbridge System (Lines 1 and 5) during the height of the propane price increases this winter,[78] indicating that pipeline capacity does not appear to be an exacerbating factor even during periods of exceptional demand.

6.4 Rail already delivers propane from west to east and its role is expected to increase as it begins to deliver some of the volumes previously transported by Cochin. Approximately 33 rail tank cars per day are needed to do so.[79] Market participants have indicated that some firms have already begun to make the necessary investments and obtain required approvals to expand rail infrastructure to offset any impact from the Cochin pipeline reversal.

6.5 For example, in February 2014, midstream operator Keyera announced construction of a propane rail terminal near Fort Saskatchewan, Alberta, with a targeted start-up date of mid-2015.[80] Keyera also announced that it would expand its underground storage capabilities, through the addition of two new salt caverns in Fort Saskatchewan, in order to meet demand.

6.6 Kinder Morgan and NOVA Chemicals have proposed to continue the Cochin pipeline in west to east service for the section of line east of Riga, Michigan.[81] The proposal, named the UTOPIA pipeline project, would deliver a mix of previously refined or fractionated natural gas liquids, including propane and ethane, to petrochemical and fuel markets in Ontario. The mix of liquids would originate from shale gas-processing facilities in Ohio and be delivered to Windsor, Ontario. The pipeline is expected to have an initial capacity of 7,950 cubic metres per day (50,000 barrels per day) and be operational by mid-2017.

6.7 In light of this planned transportation infrastructure, gradual demand growth, and declining but eventually rebounding supply, there does not appear to be a long-term imbalance in the Canadian propane market. There will be industry adjustments (including increased reliance on storage and inventory accumulated during the summer) due to supply and demand developments, but there do not appear to be significant domestic factors that would exacerbate the market challenges experienced this winter or that would lead to sustained shortages or price increases. This conclusion is reinforced by the U.S. factors discussed below.

U.S. Situation

6.8 U.S. propane production is expected to grow significantly in the near term. This is due to growth in NGL production from gas plant processing, which is in turn due to horizontal drilling and hydraulic fracturing technologies that are increasing U.S. production from shale and tight gas basins.[82] For example, total NGL production (which is mostly propane) from the Marcellus and Utica shale formations[83] is forecast by the EIA to increase from 60,000 barrels per day in 2013 to at least 650,000 barrels per day in 2016. At least 39 gas processing projects have been announced or planned in these two basins, including seven new gas processing plants.[84] A portion of this expanded production will be available to provide additional propane supplies to markets in both Canada and the U.S.

6.9 According to a 2013 report prepared by ICF International for the Propane Education and Research Council,[85] U.S. propane production from gas plants and refineries is forecast to increase twenty per cent between 2012 and 2020. This increase is in addition to the twenty per cent increase that already occurred between 2005 and 2012 (as shown in Figure 5.7). The same report projects that U.S. propane demand is expected to grow slowly until 2020.

6.10 Industry analysts forecast that the trend of growing U.S. exports to overseas markets will continue in the near and long-term. Targa and Enterprise, who completed major export facility expansions in 2013, have already announced plans for further expansions. Other U.S. companies have also announced new projects. Most of these new export terminals are scheduled for completion in 2015, when the expected expansion of the Panama Canal will improve access to growing propane markets in Asia. By 2017, the U.S. Gulf Coast’s export capacity for propane could exceed 220,000 cubic metres per day (1.4 million barrels per day), which is more than triple the 2013 capacity.[86]

6.11 Even with surplus U.S. propane for export, which could be redirected to domestic markets in times of high demand, shortages and price increases such as those experienced this winter may still occur. In periods of very high propane demand, pipeline capacity is limited. Alternatives such as rail and trucking also have capacity limits and can be delayed by cold weather, especially over long distances. Even when price incentives and policy directions are in place, as they were by February 2014, these logistical challenges mean that extra time may still be needed to re-direct propane supplies.

6.12 Additional logistical challenges can also come into play. In the case of the U.S. East Coast, propane needed to be delivered from Europe and North Africa this winter, not only because U.S. propane pipelines were fully committed, but also because there were no U.S.-flagged tankers available to ship propane from the Gulf Coast to the East Coast.[87] The volumes imported may have also been limited by the storage capabilities of the receiving areas.[88]

6.13 Due to the integrated nature of the Canadian and U.S. propane industries, these delays in the resupply of the U.S. Midwest and East Coast will have an impact on Canadians during times of tight supply. The market will respond and eventually lower prices, as it did this winter, but time lags should be expected.

7. Examination of Anti-Competitive Behaviour

7.1 Canadian consumers have experienced high propane prices this winter. In situations where demand is high and supply is tight, this can be an expected short-term result of the market, as prices reflect the scarcity of the good and adjust to allocate the limited supplies of that good to their highest value use in the economy.[89] In circumstances where high prices occur in an efficient market, economic welfare is maximized by allowing these high prices to persist.[90] High prices can encourage additional supply which would ultimately tend to moderate a short term price increase.[91]

7.2 However, high prices can also result from market inefficiencies. In some circumstances, elevated prices may be the result of an exercise of market power[92] or an illegal agreement to fix prices in all or part of an industry. In these circumstances, high prices become a symptom of anti-competitive behaviour rather than the outcome of an efficient market. When firms engage in anti-competitive conduct, this typically results in high prices, less selection, lower quality products or services, and a reduction of innovative offerings.

7.3 Some types of anti-competitive conduct can be imposed unilaterally by a single firm, without the need for cooperation between market participants.[93]  This type of behaviour is more common when markets are served by a small number of firms and when barriers to entry and expansion are high. Otherwise, when customers have choice among many competing alternatives, there is a greater potential that customers can switch their purchases to other firms in sufficient numbers to deter anti-competitive behaviour.[94]

7.4 Alternatively, a group of firms can, tacitly or explicitly, coordinate their marketplace actions to effect anti-competitive results. Markets may be more susceptible to this type of behaviour when firms can: (a) mutually recognize the benefits from competing less aggressively with one another; (b) monitor the conduct of other firms and detect deviations from the terms of coordination; and (c) respond to deviations through credible deterrent mechanisms.[95] When a group of firms engages in coordinated behaviour with anti-competitive outcomes, this conduct can be subject to the civil provisions in the Competition Act.[96] When firms coordinate their behaviour by engaging in price fixing, bid rigging, or market allocation, this can constitute an indictable offence under the Competition Act, and those found responsible can be subject to imprisonment and fines.[97]

7.5 High prices can also result in times of shortage, typically following disasters or other events that disrupt the normal flow of goods, when sellers use marketplace disruption to artificially increase prices.[98] This is commonly known as “price gouging”, and is another situation where an inefficient market can result in higher prices. Charging high prices is not, by itself, prohibited in the Competition Act; high prices are a concern under the Competition Act when they are the result of anti-competitive conduct.[99]

7.6 While economics provides several different models of firm interaction, the basic premise behind industrial organization economics and competition policy is that more competition results in a more efficient allocation of resources in the economy. When firms engage in the types of behaviour discussed above, market distortion and inefficiency can occur, which can result in higher prices to consumers and harm to the economy. Given the fact that propane is an essential good for some consumers, any such anti-competitive activities would be likely to have substantial negative effects on Canadian consumers.

Scope and Conduct of Examination

7.7 The Bureau has undertaken an examination of whether Canadian propane markets have been subject to anti-competitive activities that may have exacerbated the impact of recent propane price spikes on consumers. In conducting this examination, the Bureau has completed interviews with a broad range of industry stakeholders, and has reviewed information supplied on a voluntary basis by market participants. The Bureau also attempted to undertake a quantitative review of propane pricing, which is discussed in further detail below.

7.8 This examination was not a formal inquiry under the Competition Act. In this respect, the Bureau’s examination relied on the voluntary participation of industry stakeholders and, in a market study like the current examination, the Bureau does not have the ability to use formal information gathering tools pursuant to the Competition Act.

7.9 The Bureau's findings, as reflected in this report, are not findings of fact or law that have been tested before a tribunal or court. Competition enforcement decisions are made on a case-by-case basis and the conclusions discussed in the report are specific to the present matter and are not binding on the Commissioner of Competition. Readers should exercise caution in interpreting the Bureau's assessment.

7.10 Based on the information collected, the Bureau’s examination has not found sufficient evidence, at this time, to conclude that anti-competitive activities have exacerbated the impact of recent propane price spikes on consumers. Should any person have information regarding anti-competitive activities that have occurred or are occurring in Canadian propane markets, this information should be provided to the Bureau, and the Bureau will not hesitate to take the appropriate action if it becomes aware of anti-competitive conduct that contravenes the Competition Act.[100]

Analysis of Upstream Production

7.11 One symptom of anti-competitive behaviour is excess profits being earned by market participants.[101] As mentioned above, the Bureau’s general practice when assessing anti-competitive behaviour is to determine whether market participants have the ability to exercise market power by influencing price above a competitive level. In circumstances where a market participant can exercise market power, it is generally expected that such a firm will earn excess profits.

7.12 Market participants in the Canadian propane industry have generally noted that upstream propane producers realize the greatest financial benefit when propane prices rise, and bear the largest risk when propane prices fall. This is generally because midstream and downstream propane firms make contracted purchases and sales of propane against one or more indexed prices from major North American propane hubs, such that their cents-per-litre margin remains constant regardless of the ultimate price of the propane. Therefore, it is perhaps most likely that anti-competitive behaviour would occur at the upstream level of the industry, as upstream producers have the greatest ability to directly gain from higher propane prices.

7.13 However, the Bureau received no complaints from either midstream or downstream market participants about the pricing practices of upstream firms during the recent periods of high propane prices. Since upstream firms sell their propane directly to midstream or downstream firms, it is likely that these customers would be well positioned to recognize and report any attempt by upstream firms to raise prices above a competitive level. While it may be difficult to recognize anti-competitive behaviour during times of rapidly rising prices, it is worth noting that most midstream and some downstream market participants have a significant history and expertise in Canadian propane markets, and the sophistication of these customers, coupled with the fact that these customers would not likely benefit from higher propane prices, reduces the likelihood that an exercise of market power by upstream firms would go undetected.

7.14 It also appears unlikely that any one upstream firm could profitably influence prices, as propane production at the upstream level is spread across a reasonably large number of firms. Since many independent companies produce propane in Canada, it does not appear likely that a single producer, acting alone, could unilaterally raise prices, as any such attempt would likely be disciplined by customers obtaining supplies from other upstream producers. Having said that, the Bureau notes that there are relatively few producers of propane in Ontario and Quebec, and in periods where rail infrastructure is significantly congested, there is a greater possibility that such behaviour could result.

7.15 Certain upstream production facilities in Canada experienced outages and maintenance periods either during or immediately before January and February 2014, when propane prices reached their highest levels. These outages could also be a symptom of an exercise of market power if such an outage could sufficiently restrict supply to influence prices upwards. However, it appears that these outages resulted from legitimate safety and/or maintenance needs, and were not a result of attempts by upstream producers to limit supplies and realize higher prices. Furthermore, given the fact that upstream production supplies a reasonably small proportion of overall supply during the winter months, it is not clear that one single propane producer unilaterally restricting supply could have a material effect during the short periods of time in which the outages occurred.

7.16 Finally, even though upstream producers may benefit the most from a propane price increase, a key cause of higher than normal pricing during this winter involved congestion and low inventories at midstream transportation and storage assets, and not at the upstream production level. Upstream propane producers that do not participate at other levels of the industry would likely have little direct ability to influence the midstream level of the marketplace.

Analysis of Midstream Firms

7.17 An exercise of market power by midstream rail, pipeline, or storage firms could bear resemblance to the supply shortage issues experienced this winter. In other words, midstream transportation firms could restrict supply available for transport in an attempt to increase propane prices, or midstream storage firms could deliberately keep inventory levels low to create an artificial supply shock that would also result in high prices.

7.18 In the case of rail firms transporting propane across Canada, the issues experienced this winter appear to be well understood consequences of extreme winter weather, and do not appear to be unique to this recent shortage period. Therefore, it appears unlikely that the service disruptions experienced this winter are the result of an exercise of market power by rail companies.

7.19 Propane is also moved across Canada by pipeline. In the case of the Cochin pipeline, the decision to reverse the pipeline, and the regulatory approvals necessary for the plan to be affected, were all made in advance of the recent shortage period. Kinder Morgan’s decision to reverse the pipeline appears to be more likely related to low historical capacity utilization on Cochin and new demand for condensates in western Canada, rather than being motivated by a desire to increase propane prices. Furthermore, Kinder Morgan has no other propane related assets in Canada, and restricting supply in order to increase prices would not likely bring any benefit.

7.20 With regard to the Enbridge System, the rates that Enbridge charges its shippers are regulated by the NEB and FERC. This regulatory oversight restricts Enbridge’s potential ability to raise rates for its own financial benefit. Additionally, Enbridge participates only at the midstream level of the Canadian propane industry, and does not take ownership of the NGL transported via its pipelines. Finally, in 2017, the eastern portion of the Cochin pipeline will once again be available to transport NGL into Ontario from the U.S. Midwest.

7.21 The structure of midstream processing and storage assets in Ontario may make these markets more susceptible to an exercise of market power. Specifically, in southern Ontario, these assets are generally owned by a small number of firms and are substantially controlled by a single operator. However, the evidence gathered during the Bureau’s examination is not consistent with any strategy to restrict supply or otherwise influence propane pricing in Canada. Several firms indicated their intention to expand their propane storage capacity in eastern Canadian markets, which is inconsistent with a strategy to limit supply in order to raise prices.

7.22 Furthermore, as discussed above, high demand for propane this year created, or contributed to, congestion issues at midstream facilities. While congestion could be a side effect of an anti-competitive supply restriction, it appears to be well supported that demand for propane was considerably higher this winter than in previous winters, and that this increased demand was a significant contributor to congestion at midstream supply sites.

Analysis of Downstream Distributors

7.23 During the 1990s, Superior Propane and ICG Propane operated as the two major propane suppliers across a large number of Canadian propane markets. In 1998, Superior Propane acquired ICG Propane and, following completion of the acquisition, the Commissioner of Competition applied to the Competition Tribunal seeking to dissolve the acquisition on the grounds that the merger would lessen or prevent competition substantially in 74 local propane markets across Canada.[102] The application was fully contested in front of the Competition Tribunal and the courts but, ultimately, the Commissioner’s application was dismissed, and Superior Propane became the sole or dominant supplier in a large number of Canadian propane markets.

7.24 Since that time, however, local propane markets have seen the establishment of new downstream propane distributors. Some market participants have indicated that consumer switching from fuel oil to propane for home heating may have contributed to demand increases that induced new downstream firms to commence operations in certain local retail markets.

7.25 For the purpose of competition analysis, what is important is the extent to which firms in a market can act as a competitive constraint to each other, and not simply participate on the fringes of the market. In this sense, the Bureau differentiates between firms merely providing service in a market, and those firms who can effectively compete in that market. The extent to which downstream distributors can act as effective competitors depends on, at least: the firm’s ability to independently source propane supply, its storage capacity, number of delivery trucks, customer base, and ability to offer value-added services to consumers. In other words, a downstream distributor is more likely to act as a competitive constraint when: it does not have to rely on its competitors to obtain propane supplies; it has significant storage assets and delivery trucks to serve a large customer base sufficient to achieve a competitively low cost; and it has the ability to offer quality service to its customers.

7.26 To examine the extent to which downstream propane markets have experienced effective entry, the Bureau surveyed the operations of more than twenty-five downstream distributors of propane in the regions of Ontario and Quebec that were most affected by this winter’s high propane prices.[103] This analysis showed a significant amount of entry into local propane markets in the past five years, and concluded that a minimum of two, and in many cases more than two, suppliers likely act as effective competitors in each local market. While the nature of this examination prevents the Bureau from concluding that all of these markets are served at a competitive level, it appears likely that local propane markets are not subject to the same level of market dominance as may have been the case immediately following the Superior Propane-ICG Propane merger.

Analysis of Propane Pricing

7.27 In previous market studies, the Bureau has been able to use marketplace data to quantitatively assess whether, and the extent to which, market participants may possess market power. For example, in 2005, the Bureau was able to undertake an econometric analysis of local gasoline markets across Canada, and conclude that abnormally high gasoline prices observed in 2004 were the result of “market conditions”, rather than anti-competitive behaviour by market participants.[104]

7.28 The Bureau has been unable to perform a similar quantitative analysis for this report, primarily due to necessary data being unavailable. Specifically, the Bureau attempted to perform a “difference-in-difference” analysis, which compared wholesale pricing at certain Canadian propane hubs to the same pricing at a certain U.S. benchmark hub in an attempt to determine whether propane prices at these Canadian hubs increased relative to propane prices at the U.S. hub after controlling for local market conditions.[105] If Canadian price increases are not explained by local market conditions, then differences in prices may be symptomatic of an exercise of market power.

7.29 This econometric analysis could not explain a substantial portion of pricing variability at Canadian propane hubs. However, it is not clear whether this unexplained variation is the result of market power or is caused by a lack of sufficient information to control for differences in supply and demand conditions between the markets being studied. Ultimately, the Bureau is unable to assert that this analysis is evidence of market power being exercised.

7.30 The Bureau would have been able to obtain clearer results with access to better data. For example, a comparison of wholesale pricing between Canadian and U.S. hubs would benefit from additional information on the types and amounts of end-use demand that are sourced from each hub, and these data are not publicly available. As another example, the Bureau is aware that certain propane production and transportation assets experienced temporary disruptions during this winter, but data to accurately describe the extent of these disruptions are generally not publicly available.

7.31 Additionally, the Bureau’s analysis would benefit from more timely access to Canadian data, as there is a significant time lag before these data are collected, compiled, and made available. Even as of now, key data describing the full extent of production and consumption during the January and February 2014 price spikes remain unavailable.

7.32 Furthermore, even if the Bureau had obtained robust results with the available data, differences in posted wholesale prices provide no information about the extent to which market power may have been exercised by downstream distributors. In order to examine downstream issues, retail pricing information would need to be available for each end use, and these data are not collected in Canada. The issues associated with accessing necessary data have, at least in part, limited the Bureau’s ability to quantitatively assess whether anti-competitive activities may have exacerbated the impact of recent propane price spikes on consumers.

Conclusion Regarding Anti-Competitive Behaviour

7.33 At this point in time, the Bureau has not found sufficient evidence to conclude that anti-competitive activities have exacerbated the impact of recent propane price spikes on consumers. However, the Bureau notes that this examination of propane market issues is limited by certain factors discussed above and, should any person have information regarding anti-competitive activities that have occurred or are occurring in Canada propane markets, this information should be provided to the Bureau, and the Bureau will not hesitate to take the appropriate action if it becomes aware of anti-competitive conduct that contravenes the Competition Act.[106]

8. Conclusions

8.1 The Canadian propane industry encompasses upstream producers, midstream storage and transportation companies, and downstream distributors. This wide-reaching supply chain works together to provide propane to Canadian end-users.

8.2 The Canadian and U.S. propane industries are integrated and Canadian propane prices, supplies, and infrastructure are linked to major propane trading hubs in the U.S. Canada exports significant amounts of propane to the U.S. These commercial realities are supported by a longstanding, market-oriented regulatory framework for propane and other energy products.

8.3 This winter, a unique combination of unusually cold weather, high U.S. agricultural demand, lower-than normal inventories, and rapidly growing U.S. overseas exports led to tight supplies and increased prices in Canada and the U.S. This price increase had a significant impact on Canadians, including households that use propane for home heating.

8.4 Propane prices moderated after peaking in January, as inventories recovered and propane stored in the U.S. Gulf Coast was redirected to the U.S. Midwest. Canadian prices did not spike to the same extent as in the U.S. Additionally, reports of the local shortages concentrated in Ontario and western Quebec did not continue throughout the winter. The market responded, although factors such as logistical challenges and the propane industry’s inherent inability to significantly increase production in the short term, prevented consumers from obtaining relief more immediately.

8.5 The Bureau’s examination did not uncover sufficient evidence, based on the information collected during its review, to conclude that anti-competitive activities exacerbated the impact of recent propane price spikes on consumers.

8.6 This winter’s price increases and initial local shortages are not indicative of long-term supply-demand imbalances in the Canadian propane industry. Short-term propane prices have historically been volatile due to the industry’s traditional combination of steady supply, fluctuating demand, and complex logistics. While there is sufficient production, storage, and transportation infrastructure to meet the future needs of Canadians, utilization of this infrastructure throughout the year is often based on market expectations of variables such as weather. Accordingly, temporary price spikes and shortages are likely in the future. No other factors are expected to exacerbate these challenges or contribute to future shortages and price increases.

8.7 Long-term supply and demand of propane in Canada is projected to be relatively stable, as is long-term U.S. demand. U.S. supply is expected to grow significantly in the long term, with this surplus mostly flowing overseas as exports. The growing U.S. surplus may provide some additional relief in times of very high demand in Canada and the U.S., as it did this winter.

Appendix: Data Sources and Challenges

A.1 The NEB and the Bureau analysed a significant amount of data while preparing this report. Nonetheless, challenges were encountered with regard to the availability of timely, detailed, and high-quality data on the Canadian propane industry. The lack of such data can hinder the ability of governments, regulators, and industry participants to identify in a timely and precise manner what, if any, measures should be taken in response to propane market events such as those that occurred this winter.

A.2 Statistics Canada reports Canadian propane supply and disposition data on an annual basis in CANSIM Table 128-0012.[107] The data reported in this CANSIM table comes from multiple sources and is collected with different methodologies. For example, some of the data in the table comes from the NEB’s Product Supply and Disposition Report, which the NEB provides to Statistics Canada but no longer publishes. Industrial consumption figures come from Statistics Canada’s large-sample Industrial Consumption of Energy survey. Other industry data comes from Statistics Canada’s surveys of producers and end-users.

A.3 A consequence of the various data collection methodologies is that the reported Canadian propane production, consumption, and export numbers are not consistent. When calculating availability and net supply figures for propane, Statistics Canada includes an item referred to as “other adjustments” which includes “cyclical billing variations, metering differences and losses in transportation”. In 2012, this addition to net supply was approximately 4,145 thousand cubic metres, which is equivalent to more than a third of the figure for total Canadian supply.

A.4 With regard to Canadian propane export data, the NEB collects data from holders of export licenses and orders issued pursuant to the NEB Act and its regulations. Under section 5 of the National Energy Board Export and Import Reporting Regulations, persons holding a propane export licence or order shall submit to the Board on a monthly basis information pertaining to the export of propane (volume, price, destination and mode of transport), and the supply and disposition of propane volumes, including opening and closing inventories. The NEB aggregates the information provided by holders of propane export authorizations and publishes it on the NEB website on a monthly basis.

A.5 By comparison, data on the U.S. propane industry comes primarily from the EIA, which is a part of the U.S. Department of Energy and is responsible for the collection, analysis and dissemination of energy information. The majority of the EIA’s data surveys are based on mandates set forward in the Federal Energy Administration Act of 1974 and the Department of Energy Organization Act of 1977. In the latter, section 205 established the EIA as the authority to carry out a central, comprehensive, and unified energy data and information program.

A.6 The EIA reports a broader range of propane data, and with greater frequency, than any source in Canada. For example, residential propane prices for each U.S. region and state are reported on a weekly basis. Also reported weekly are regional propane statistics for underground inventories, production, demand, exports, and imports.

A.7 In a 2004 document entitled “Looking Ahead to 2010: Natural Gas Markets in Transition”, the NEB noted widespread industry recognition that energy information in Canada is more widely dispersed than in the U.S., where the EIA offers a “one-stop shop” approach to energy data.[108]  In the 2004 report, the NEB noted that industry participants suggested “a central repository for Canadian energy information would be very useful in helping market sectors and governments make timely and informed decisions”. More recently, the Canadian media have also written about data gaps in the Canadian energy industry, particularly with respect to the need for up-to-date data.[109]

A.8 Collecting and publishing propane industry data in Canada comparable to what is available in the U.S. may be facilitated by increased coordination and information sharing between: federal, provincial, and territorial governments and regulators; organizations within each level of government; and governments and industry.

[12] Natural gas is first processed at gas plants to produce a mix of pipeline gas and natural gas liquids. “Fractionation” is the process of splitting a stream of natural gas liquids into components (or fractions, including propane) through a distillation process.

[14] Suppliers prefer that customers stay within a certain percentage of their contracted volumes. Buying less than contracted volumes during summer months can result in either: (a) smaller monthly allocations for midstream and downstream customers during winter months, or (b) a deterioration of the business relationship between the upstream firm and their midstream or downstream customer. If customers take possession of less than contracted volumes in the winter (e.g., because of a milder-than-expected winter), the supplier is left holding the product and would typically store it for future sale, or send it via rail to other markets in Canada and the U.S. or, ultimately, overseas.

[15] However, despite this practice, some downstream customers have noted that, in past winters, suppliers were willing to provide volume at contracted rates over and above contracted volumes.

[17] Storage caverns are also operated at Marysville, Michigan, which is approximately 20 kilometres from Sarnia and 90 kilometres from Windsor. These caverns are connected to storage caverns at Sarnia and Windsor by pipeline, train, and truck infrastructure.

[18] Underground storage capacity is variable and depends on the quantity of brine in the cavern. Underground storage capacity is expected to increase in the coming years at certain storage caverns through increased efforts to remove excess brine.

[19] These figures are for “specification” (HD-5) propane only. Underground inventories are updated and published monthly by the NEB at:

[21] In any industry, the economic range of a transportation asset contracts and expands in response to prices. In situations where rail infrastructure is congested or delayed by inclement weather, trucks may offer more timely delivery than rail cars and the effective radius of trucking may expand.

[22] A configuration of the entire Enbridge System (Canadian Mainline) is available online at:

[23] “Propane-plus” is a mixture of propane, butanes, and condensate.

[24] Pipelines that move different types of liquid hydrocarbons inject each one in a sequence, creating separate parcels or “batches” that are pumped one after another in the pipeline.

[25] Several other pipelines deliver NGL from the U.S. to the Sarnia area, including the Kalkaska Pipeline, which transports NGL from gas processing facilities in Kalkaska, Michigan, and the SCL Pipeline, which connects Sarnia to NGL storage caverns in Marysville, Michigan.

[28] For example, trains are typically 10,000-12,000 feet long, while shorter trains used during cold weather can be 5,000-5,500 feet long.

[29] Distributors in southern Ontario are primarily supplied by trucks from Sarnia truck terminals. Some of these trucks continue into western Quebec, though rail likely becomes more economical when propane is shipped as far as Montreal. Distributors in northwestern Ontario may be supplied by trucks from Fort Whyte, Manitoba, or by rail.

[30] In the case of a severe shortage, additional storage assets still may not be sufficient to meet demand.

[31] Firms estimate that adding extra storage to double their effective storage capacity would cost from $250,000 to $500,000 and take approximately one year to become operational. Contributing to these costs are tightened regulations on propane storage imposed following the 2008 Sunrise Propane explosion in Toronto, Ontario.

[32] One exception may be northwestern Ontario, where a greater proportion of customers are reported to be on fixed price contracts. Such contracts do not appear to be common in any other area of Canada.

[33] See, for example, Commissioner of Competition vs. Superior Propane Inc. et al (CT-1998-002), available online at: (“Superior Propane”); Commissioner of Competition vs. Enbridge Services Inc. (CT-2001-008), available online at:; and Director of Investigation and Research v. Laidlaw Waste Systems Ltd. (CT-1991-002), available online at:

[34] At the time of the Superior Propane-ICG Propane merger in 1999, the total costs associated with converting from propane to another fuel for home heating and cooking purposes were approximately $12,300 per household. See Superior Propane at paragraph 31.

[35] Demand is “inelastic” when a small price increase results in a less-than-proportional decrease in the amount of that product being demanded. In other words, when demand is inelastic, many consumers facing a price increase will continue to purchase the product, rather than substituting their purchases to other products.

[36] This is equally true with other fuels, such as heating oil and natural gas - once a consumer chooses which fuel to use, there are often substantial costs that must be incurred to use other fuels.

[37] Statistics Canada, CANSIM Table 128-0012. The most recent data available is for 2012 and shows Canadian propane imports of 255 thousand cubic meters. Equivalent statistics from the EIA (i.e. U.S. propane exports to Canada) are not collected.

[38] The export of propane from Canada is discussed in further detail in paragraphs 3.44-3.48 and paragraphs 4.15-4.17 below.

[39] NEB data.

[40] See “Propane Prices”. Natural Resources Canada. Available online at: These data are reported by Natural Resources Canada, but are collected by Kent Marketing Services.

[41] Chemically, automotive propane is identical to propane for other end uses; however, it seems likely that different end uses have different underlying demands, and it is unclear the extent to which arbitrage is possible such that the price of automotive propane would be equal to that for other uses.

[42] When prices rise, the downstream distributor’s margin as a percentage of its costs falls, but its cents-per-litre margin remains unchanged.

[43] Propane market activities are also subject to the federal Competition Act. Section 7 of this report presents the Bureau’s independent analysis of the extent to which anti-competitive activities may have exacerbated the impact of recent price spikes on consumers.

[44] Regulation often takes the form of maximum prices based on maximum mark-ups to posted wholesale prices. As such, regulated prices are still linked to the market and fluctuate. For an example, see the New Brunswick Energy and Utility Board’s explanation of how it sets propane prices at:

[45] Related regulations are the National Energy Board Act Part VI (Oil and Gas) Regulations (Part VI Regulations) and the National Energy Board Export and Import Reporting Regulations.

[46] Exports are published monthly by the NEB at: /CommodityStatistics/?language=english.

[47] See section 118 of the NEB Act.

[48] For example, see Section 21 of the Part VI Regulations, which includes export point and volume conditions applicable to propane export licenses. Any terms and conditions must be consistent with Canada’s trade obligations.

[49] Proposed changes to the Part VI Regulations would amend propane export orders to not exceed two years, making them consistent with export orders for other regulated commodities such as natural gas, ethane, and heavy crude oil.

[50] See Section 23 of the Part VI Regulations. The NEB does not, as a matter of federal policy, apply some of the terms and conditions applicable to propane export orders, including those related to export point and volume.

[51] See Section 20 of the Part VI Regulations. There are no equivalent requirements for export orders.

[52] In 1985, the Governments of Canada, Alberta, British Columbia, and Saskatchewan signed what are known as the Western Accord and the Halloween Agreement, which significantly restructured the Canadian regulatory regime for energy.

[54] Although propane prices reached their peak at the end of January, as shown in Figure 4.1, February experienced a higher overall average price, as shown in Table 4.1.

[57] The FERC acted upon information from the Department of Homeland Security and information in correspondence from Governors, Senators and Members of Congress. The FERC also received a request to exercise its emergency powers from the National Propane Gas Association. See FERC Docket Nos. OR14-19-000, OR14-20-000.

[58] Typically, companies operating pipelines do not own the commodities shipped in their pipelines; rather, they transport commodities owned by the shippers.

[59] “Enterprise increasing TEPPCO propane shipments following US FERC order”, Platts, February 10, 2014. Available online at:

[60] Available online at: Another U.S. midstream company, ONEOK, filed tariff revisions with the FERC on January 31, 2014 to enable a section of the North Line 5 pipeline between Medford, Oklahoma and Bushton, Kansas to move propane from south to north, if operating circumstances permitted.

[61] For example, Ontario waived certain trucking rules in 2007 in response to shortages at retail fueling stations. See:

[62] This report focused on the most prominent mitigation measures pursued in the U.S. and whether equivalent action was or could be taken in Canada. The report has not explored the full range of mitigation options and the authority to pursue them, such as the powers of the federal cabinet under the Emergencies Act and the Energy Supplies Emergency Act.

[63] Participants in the Canadian propane industry lack the necessary infrastructure to export propane directly from Canada to other foreign markets. Therefore, all Canadian propane exports are made to the U.S.

[64] Spot market prices are typically not guaranteed for any length of time, and can be either greater than (in times of tight supply) or less than (in times of abundant supply) contracted prices. Participants in a spot market can be any mix of upstream, midstream, and downstream firms - literally anyone who has surplus propane at a point in time.

[65] See Environment Canada’s Climate “Glossary”. Available online at: Heating degree days measure both: (1) the amount of days that a particular geographic area has experienced temperatures below 18 degrees Celsius, and (2) the amount of the deviation from the 18 degrees Celsius benchmark. For example, two days of -20 degree Celsius weather is 76 “heating degree days” - a 38 degree deviation from 18 degrees Celsius felt across (multiplied by) two days.

[66] This graph reports heating degree days for all of Canada and not only for the areas where significant propane demand exists. Therefore, the January 2014 data point may understate the extent of cold in eastern Canada, as western Canada experienced uncharacteristic warmth during this period. Conversely, the February and March data points may be indicative of exceptional cold in all regions of Canada and not just areas with high propane demand.

[67] Storage capacity must be rented, so firms have an incentive to forecast conservatively in order to minimize costs. In the case of a firm that owns storage assets, there is an opportunity cost associated with filling those assets with its own propane, as opposed to having sufficient excess capacity available for rental to third parties. In years where this conservative forecasting leads to shortages at any one firm, extra supplies can be acquired via a spot market. This year, few market participants had excess propane, and spot markets were unable to fulfill this role.

[68] Conway is a key propane storage and trading hub in Kansas and is closely linked with areas in the Midwest affected by the tight supply situation. See Figure 3.5.

[69] “Corn Pile Biggest Since 1994 as Crop Overwhelms Use: Commodities”, Bloomberg, January 9, 2014. Available online at:

[70] Corn producers generally do not have the option of letting crops dry in the field, and rely on large dryers to remove excess moisture prior to storage.

[74] This figure provides a direct price comparison and does not consider the cost of shipping propane to Europe. For propane exports to Europe to be economical, the European price must be high enough to offset terminalling costs at an export facility in Houston, loading costs for getting the propane into tankers, and freight costs from Houston to a European port capable of receiving propane. These costs create an incentive to keep propane in U.S. markets, even when U.S. prices are somewhat lower than European prices, as long as there are no logistical challenges preventing internal U.S. distribution.

[75] In 2012, the United States became a net exporter of propane (and other gas liquids) for the first time in decades, and exports have continued to increase since then. Primary export markets for U.S. overseas shipments of propane include: Latin America, the Caribbean, Europe, and East Asia. As mentioned previously, U.S. exports to Canada are minimal and not tracked by the EIA.

[78] “Apportionment” is a form of rationing used on a pipeline when demand for space exceeds the available capacity. Although Line 5 of the Enbridge System is often apportioned, this was not the case during December 2013 and January 2014. Line 1 of the Enbridge System was not apportioned at any time this winter, nor was the Cochin pipeline. On January 31, 2014, at the height of the price increases, Kinder Morgan issued a press release stating that, among other things, Cochin had capacity to handle additional propane shipments at that time.

[79] This assumes a 50 per cent utilization of Cochin (based on historical numbers), amounting to approximately 4,000 cubic metres per day of propane from western Canada, and a rail tank car capacity of 120 cubic metres.

[92] Market power is the ability of a firm (or group of firms) to profitably influence price above a competitive level for a significant amount of time. In most cases, when a firm exercises market power, economic efficiency is harmed.

[93] For instance, a dominant firm may implement strategies that raise the costs for entrant firms to compete effectively against the dominant firm. Alternatively, a firm may: impose a requirement that it act as a sole supplier to a customer; engage in tied selling; refuse to supply a customer; influence the price at which a product is resold; or employ other behaviour that results in market power being created, preserved, or enhanced.
