Yesterday’s Capacity Market auction secured 42.4 gigawatts of capacity for delivery year 2025/26, at a price of £30.59 per kilowatt-hour. [1]

Commenting on the results, Dr Simon Cran-McGreehin, Head of Analysis at the Energy and Climate Intelligence Unit (ECIU) said:

“By securing this back-up generation, this latest capacity auction is helping to cut the costs of the electricity system by enabling the UK to make the most of cheap renewables.

“Even with the higher clearing price in today’s auction, the costs of providing this security are dwarfed by the costs of the gas crisis that’s directly adding at least £500 to household bills from April and driving almost all of the 54% hike in home energy costs.

“When these capacity contracts kick in, the UK will have an extra 6GW of offshore wind installed, giving homegrown, net zero power that’s free from international interference and that pays back in a gas crisis – in addition to today’s wind farms that are set to pay back at least £660million during the current gas crisis.” [2]
