Clarification on Ratcliffe on Soar power station closure date

Ratcliffe on Soar power station has four 500MW units in total. Three of the units at Ratcliffe already have capacity market agreements in place and there has been no change to our commitment to operate these three units until the end of September 2024 when the power station will close in line with government policy. 

In 2021, we announced that the remaining fourth unit would close earlier in September 2022. Last year, the Government asked Uniper to explore the possibility of keeping the unit at Ratcliffe power station, due to close in September 2022, open for longer. We were pleased to announce that we’re able to support the Government’s request, and the unit was made available to the system operator to dispatch if needed, until 31 March 2023.

As requested by Government, Uniper looked at whether it can continue to have four units at Ratcliffe available to run under standard market arrangements for another winter. Uniper prequalified it’s fourth Ratcliffe Unit, in line with the rules, to take part in the Capacity Market T-1 auction for 2023/24, held in February, and was successful in securing an agreement. The unit will then close along with the rest of the power station, at the end of September 2024, in line with Government policy.
