Primary energy production decreased 0.6% year over year to 1.9 million terajoules in May, on the heels of a 0.7% increase in April. This was the first year-over-year decline in production since January 2022. Reasons for the decline in May 2023 include several natural gas facilities in Alberta, which were impacted by forest fires as well as lower crude oil production (-2.6%) due to annual maintenance at a number of oilsands upgrading facilities and bitumen mines.
Secondary energy production increased 8.7% in May, due to higher output of refined petroleum products.
