But zero-emissions sources accounted for almost 74% of the total increase in generation, with thermal generators, overwhelmingly coal, contributing just 26%.
Generation from wind farms increased by 100 billion kWh (22%) compared with the previous year, while output from solar power increased by 45 billion kWh (30%).
There were smaller proportional contributions to growth from thermal generators (63 billion kWh, just 1%), hydro-electric units (28 billion kWh, 3%) and nuclear (4 billion kWh, 1%).
Wind farm capacity increased 17% while solar capacity increased 29% in the first nine months of 2022, compared with the same period of 2021.
In absolute terms, coal-fired generation is still rising, but the growth rate has halved over the last decade, and coal generation has been growing more slowly than generation as a whole.
