The latest capacity market auction – designed to secure capacity for four years ahead - cleared today at £18.00/kW.

The provisional results show the following EDF units secured one-year agreements for the period October 2024 to September 2025:

  • 4 nuclear units (2 Sizewell B units, Torness Unit 2 and Heysham 2 Unit 8)  
  • All 3 West Burton B units
  • 2 Pivot Power new build battery units (Cowley and Kemsley)

In addition 2 Pivot Power new build battery units (Coventry and Bustleholme) have been provisionally awarded 15-year agreements for the period October 2024 to September 2039

EDF chose not to enter any of the units at Heysham 1 or Hartlepool nuclear power stations into this auction. The current scheduled closure date for both stations is Q1 2024.

Dungeness B Unit 22 also did not enter into the auction. Under the capacity market rules, for it to qualify it would have had to generate within the previous 2-year window, which it has not. Dungeness B has unique technical challenges and is currently scheduled to restart in May this year.

Securing low carbon supplies for the UK

The capacity market aims to secure electricity supply at least cost to customers. This investment has made a critical contribution to the UK’s security of supply.

The energy mix in the UK is changing. EDF is investing significantly in new nuclear, renewable generation and battery storage, as well as helping customers to use energy more efficiently.

About EDF in the UK

EDF in the UK is leading the transition to a cleaner, low emission electric future, tackling climate change and helping Britain reach net zero. It is the UK’s largest producer of low-carbon electricity, meeting around one-fifth of the country’s demand and supplying millions of customers with electricity and gas.

It generates low carbon electricity from eight nuclear power stations, more than thirty onshore wind farms and two offshore wind farms, and operates one of Britain’s biggest battery storage units, one gas and one coal power station, EV charge-points, and combined heat and power plants.

EDF is leading the UK's nuclear renaissance with the construction of a new nuclear power station at Hinkley Point C, and plans for new power stations at Sizewell C in Suffolk and Bradwell B in Essex. Hinkley Point C will provide low carbon electricity to meet 7% of UK demand. The project is already making a positive impact on the local and national economy as well as boosting skills and education.
