According to the International Energy Agency’s ‘Monthly Electricity Statistics’ report global electricity production is rising again after some months of piecemeal reductions. 

For the total OECD membership, net electricity production amounted to 879.0 TWhin September 2023, up by 1.3% compared to September 2022 contrasting with a fall of 2.3% in production y–t–d over the first three quarters of 2023 when compared to the same period last year.

This decrease was mainly driven by reduced electricity generation from fossil fuel sources (-5.6% y-t-d), led by lower electricity production from coal power plants (-15.2% y-t-d). Electricity generation from natural gas slightly increased in the first three quarters of 2023 (+0.9% y-t-d). Overall, the share of fossil fuels in the OECD electricity mix was 52.5% in September 2023, meaning 1.2% lower than in September 2022.

Electricity production from renewable sources increased over the first three quarters of 2023 (+1.2% y-t-d), mainly driven by increased generation from solar (+ 14.1% y-t-d). Conversely, generation from hydro decreased by -3.0% y-t-d, reaching a record-low share of 11.8% in the OECD’s electricity mix. The share of total renewables in the OECD electricity mix amounted to 30.8% in September 2023, almost unchanged compared to September 2022.

Over the first three quarters of 2023, electricity generation from nuclear rose by 1.3% y-t-d. In September 2023, nuclear plants accounted for 16.4% of total OECD electricity production, up by almost one percentage point compared to September 2022.

A significant fall was recorded in Canada, where total electricity generation for September 2023 showed a 6.5% year-on-year decrease, amounting to 44.4 TWh. On a year-to-date basis, total net electricity production fell by 3.2%. This downturn was primarily driven by a 6.2% y-t-d drop in hydroelectric generation, which fell to 24.5 TWh in September 2023. These figures represent the lowest levels for both overall electricity generation and hydroelectric production for more than a decade. The decline was notably impacted by the record-breaking warmth observed during this period, marking the warmest September on record in North America.

The IEA’s Monthly Electricity Statistics report features electricity production and trade data for all OECD Member countries and electricity production data for a selection of other economies. IEA has now moved to a new integrated platform, and in order to access data, users will need to login using an IEA account, which can be created on the IEA website.
