‘Here in Alberta prices have risen, but so far the increases could be described as minimal, especially since 2020, and the past 5 years has had relatively low gas prices. The Alberta price in September 2021 for natural gas increased to $3.87/GJ (Gigajoule), the highest price it’s been for the past 5 years.’

Since the fall of 2016, Alberta’s price of natural gas has spent approximately 85% of the time under $3.00/GJ, and 75% of the time priced less than $2.50/GJ. The most recent 5-year average price comes in at $2.42/GJ, which means the recent increase to $3.87/GJ amounts to a 60% price increase.
‘However, looking at the past 20 years of Alberta natural gas prices, it quickly becomes evident that the past 5 years have indeed been low cost. From 2001 to 2011, natural gas averaged $5.92/GJ, whereas prices from 2011 to 2021 average just $2.78/GJ.’

‘The last time prices for natural gas were this high was in 2014, when the price spent most of the year above $4/GJ. Analysts talk about prices going to 2008 levels. If so, that would come as quite a shock, considering prices were above $6/GJ going into the 2008 commodity super cycle when prices topped out at over $10/GJ,’ explains Furtas.
