In the OECD, total net electricity production amounted to 864.1 TWh in June 2023, down by 4.5% compared to June 2022. Over the first half of 2023, electricity production dropped by 3.7% compared to the same period last year.
This decrease was mainly driven by reduced electricity generation from fossil fuel sources (-7.4% y-t-d1), led by a significant drop in electricity production from coal power plants (-17.3% y-t-d). Natural gas, on the other hand, remained in line with previous year’s levels (-0.4% y-t-d). Overall, the share of fossil fuels in the OECD electricity mix was 50.2% in June 2023, around 1.6% lower than in June 2022.
Total electricity production from renewable sources was stable over the first two quarters of 2023 (+0.3% y-t-d), as strong generation from solar (+ 12.3% y-t-d) compensated for lower output from wind (-1.0% y-t-d) and hydropower (-2.3% y-t-d). The share of renewables in the OECD electricity mix settled at 33.5% in June 2023, almost unvaried compared to the same month last year.
Over the first half of 2023, electricity generation from nuclear slightly decreased by 0.6% y-t-d, with nuclear power recovering in the second quarter of 2023 and mitigating the reduced output registered in the first quarter. In June 2023, nuclear plants accounted for 16.0% of total OECD electricity production, up by one percentage point compared to June 2022.
In the OECD Americas, total net electricity production was 465.7 TWh in June 2023, down by 2.4% on a year-to-date basis. Lower electricity generation from coal (-24.8% y-t-d) and hydro (-6.9% y-t-d) contributed the most to this decline.
In Colombia, total net electricity production amounted to 7.0 TWh in June 2023, up by 1.1% on a year-to-date basis. Over the first half of 2023, electricity production from renewables increased by 2.5% y-t-d, with hydro (+3.2% y-t-d) and solar (+65.5% y-t-d) being the main contributors. Electricity production from fossil fuels decreased by 2.4% on year-to-date basis, as higher coal-fired production (+26.8% y-t-d) only partially offset the lower power production from natural gas (-10.3% y-t-d) and oil (-22.2% y-t-d).
In Canada, total electricity generation declined by 2.8% year-over-year to 46.3 TWh in June 2023. Over the first half of 2023, electricity production decreased by 1.0% compared to the same period last year. This was driven by lower output from renewables (-1.0% y-t-d), namely from hydropower (-2.1%y-t-d), which is the main source of electricity production in the country. Conversely, electricity generation form solar increased by +97.8% y-t-d, reaching a record-high share of 2.8% in the electricity mix.
Total net electricity production in the OECD Asia Oceania region was 147.3 TWh in June 2023. Electricity production from fossil sources decreased by 10.9% on a year-to-date basis, mainly due to lower generation from natural gas (-15.4% at 38.1 TWh) and coal (-5.5% at 45.5 TWh). On the other hand, generation from nuclear and renewable sources increased on the first semester of 2023 by 11.6% and 7.8% y-t-d, respectively.
In New Zealand, electricity production from hydro achieved record levels, increasing by 19.3% y-o-y2 in June 2023 and 15.8% y-t-d. In June the share in the energy mix rose to 68.1% as the rainfall during this and the previous month was above normal in certain regions. Hydro is the main source for electricity production in the country, with a share in electricity mix ranging from 50% to 70%, however larger shares are often seen after July as reservoirs fill after higher rainfall in winter months. In 2023 though, northern regions have seen more than a year’s worth of rainfall in only the first half of the year
In OECD Europe, total net electricity amounted to 251.1 TWh in June 2023, down by 7.2% compared to June 2022. Higher electricity production from renewable sources (3.8% y-o-y) could not compensate the decline observed in fossil fuels (-24.1% y-o-y). Similarly, on a year-to-date basis, lower production from fossil fuels (-15.0% y-t-d) and nuclear (-5.0% y-t-d) over the first two quarters of 2023 drove the downward trend. Production from renewables slightly increased by 2.4% y-t-d, driven mainly by solar (13.7% y-t-d), which registered a record-high share of 14.3% in the electricity mix.
In Belgium, over the first semester of 2023, total net electricity decreased by 11.3% y-t-d compared to the same period in 2022. This decline was driven by lower electricity generation from nuclear (-27.9% y-t-d), following the shutdown of a nuclear reactor unit in January. This decrease could only be partially mitigated by the increase observed in production from fossil fuels (1.5% y-t-d) and renewables (5.7% y-t-d). In particular, electricity production from solar increased by 8.3% y-t-d, reaching a record-high share of 19.4% in the electricity mix.
In Germany, total net electricity amounted to 34.5 TWh in June 2023, down by 17.2% y-o-y or 11.2% y-t-d. This is the lowest value registered in a decade and more, due to both industrial power consumption declining and imports of electricity surging. Production from fossil fuels decreased by 16.3% y-t-d, nuclear by 57.5% y-t-d following Germany’s nuclear phase out, and renewable sources remained fairly stable at -0.6% y-t-d. In this context, solar-generated electricity reached a record-high share of 26.8% in the electricity mix.
In India, total net electricity production amounted to 156.3 TWh in June 2023. This represented an increase of 7.1% compared to June 2022, and a 5.6% increase comparing the first half of 2023 to the same period in 2022. As a result of a severe heatwave in the second quarter of the year, the country’s electricity consumption has indeed surged. Despite a significant increase in solar power production (+25.5% y-t-d), India had to rely on higher output from coal power plants (+6.5% y-t-d) to keep up with increasing demand and avoid power outages.
In Romania, electricity production from hydropower totaled 2.4 TWh in June 2023, up by 69.4% compared to the same month last year. Over the first half of 2023, electricity generation from hydropower increased by 48.3% y-t-d, mainly as a result of significant rainfall in the second quarter of 2023. In June 2023, the share of hydropower in the country’s electricity mix reached a record-high of 55.7%.
