EDF Energy statement on capacity market auction (T-1 2018/19)

Units which secured one year agreements for the period October 2018 to September 2019 at a price of £6/KW are:

  • West Burton A coal power station, unit 3
  • The new 49MW battery storage unit at West Burton.
  • 4 demand side response agreements totalling 12.8MW

The capacity market has been designed by Government to make sure that there is enough electricity generating capacity available to meet peak demand.

Customers benefit from the best possible price for capacity by having a range of technologies competing in the auction. 

The capacity market supports EDF Energy’s investment in its generating plant. In particular, it underpins EDF Energy’s substantial investment in its low carbon nuclear power stations. This has helped improve their performance, expected lifespan and reliability, making a critical contribution to the UK’s security of supply.

EDF Energy’s coal stations play a key role in providing security of supply until they can hand over to new low carbon generation. EDF Energy has already made big investments to make its coal plants fully compliant with all current emissions and environmental regulations.

In this auction, in addition to its generating assets, EDF Energy secured agreements for a total of 12.8MW of demand side response. This involves business customers being incentivised to reduce consumption or run on-site generation at times of system stress or of peak demand. Demand side response will play an important role in balancing the electricity supply system.

EDF Energy has also successfully pre-qualified all of its existing generation capacity to participate in the capacity auction for the year starting October 2021 to be held on 6 February 2018.
