More Refining Capacity In Alberta Won't Solve BC's Gasoline Price Problem


Dealing with the sky-high price of gasoline in British Columbia is a policy conundrum.

On the one hand, higher gasoline prices are exactly what the government’s greenhouse gas policy calls for. They will reduce the demand for gasoline, discourage the purchase of gas-guzzling trucks and SUVs, and hasten the shift to electric vehicles.

On the other hand, the high prices are a significant economic burden, particularly for low and middle income families. The major jump in prices in recent months is like a very regressive tax, reducing the amount of disposable income households have to meet their other basic needs.

It is clear the government sees the need to act. The only problem is that it does not appear to know what to do. 

The Premier’s call to build more refining capacity in Alberta clearly is not the answer. Firstly, Alberta will not support the construction of additional refining capacity in its province with all the financial and environmental costs that entails in order to address a gasoline pricing problem in BC. More importantly, building more refining capacity in Alberta won’t solve the problem. It isn’t a shortage of refined petroleum product supply in Alberta that is driving up prices in BC; the problem is constraints on the delivery of Alberta supply to BC.  

For many years now, BC has relied on Alberta to meet much of its demand for gasoline and other refined petroleum products. It was more efficient for the oil companies to refine in large-scale Alberta facilities serving Western Canada and to ship the product to BC than to refine here. And what was good for the oil companies would have been good for BC consumers except for one very unfortunate fact. The price of gasoline and other refined petroleum products in BC is not based on the cost of refining in Alberta plus shipping to BC. Rather, it is based on the much higher cost of supply from the major alternative source of supply for BC consumers – deliveries from Puget Sound refiners.

Puget Sound only supplies a small proportion of the gasoline and other refined petroleum product requirements in the province, but it is what economists call the ‘marginal source of supply’ – the source BC has to turn to when Alberta supply plus the limited local production is not sufficient to meet provincial requirements.  Because Puget Sound refiners are the marginal source of supply, they effectively set the market price. Shippers from Alberta can charge the delivered Puget Sound price, even if it is well above their own cost, because they are still competitive with the only available alternative. And Puget Sound is the only available alternative because of limited pipeline capacity for additional deliveries from Alberta.

That Alberta supply (and the relatively small amount produced in BC) sells well above its cost is very evident from the data on refining and marketing margins in BC versus elsewhere in Western Canada. The refining and marketing margin indicates the difference between the before-tax selling price of gasoline and the cost of crude oil – it is a measure of the gross profit from sales. The margin the oil companies realized from gasoline sales in Vancouver in March 2019 (when gasoline prices averaged a mere $1.50 per litre) was 54 cents/litre, some 20 cents per litre higher than the margin for sales in Calgary and Winnipeg which were 33 cents and 34 cents respectively. 

Puget Sound wouldn’t be the price-setting marginal source of supply for BC if there was sufficient pipeline capacity available for gasoline and refined petroleum product deliveries from Alberta. But, as we know from another story, pipeline capacity is limited and efforts to increase capacity have been frustrated by BC government, First Nation and other opposition.

Ironically, what BC needs more than anything else to bring down gasoline prices in the province is more refined product pipeline capacity, and the TransMountain pipeline expansion project that the province has relentlessly opposed could help solve that problem. Short of that expansion project going ahead, along with some assurances about the competitive access to capacity for gasoline and other refined petroleum product deliveries, there is no simple solution in sight. Accepting the economically troubling but environmentally pleasing exorbitant prices could well be the answer, along with further government initiatives to support low and middle income families to ease the disproportionate burden of excessively high energy prices.

  1. I've been saying much the same thing; why can't TMPL be persuaded to ask its dilbit shippers to hold back and make more room for gasoline until Puget Sound and Bby refineries are all back up and running? Maybe two weeks. Commenters say NEB has no jurisdiction to change contracted shipments but maybe political suasion for sake of Canadian co-operation could help a bit? You know, let saner heads prevail stuff.

  2. I think you misunderstand the problem. Had there been some “Canadian cooperation” this pipeline and northern gateway would’ve been built by now and Alberta could send you all the gasoline you wanted. The pipeline is a free market, they’re not going to cooperate to give the same people a low price on fuel that have been blocking them every step of the way and lose even more money on their oil barrels. If Vancouver wants better prices then it should improve market access so that the prices have to be competitive. That means another pipeline.
