The UK Capacity Market remains an important part of the UK energy market design and has provided stability for our generation business over the past decade. However, we recognise the difficulty facing families and businesses with rising energy prices. As one of the largest generators in the UK we are committed to investing and expanding our green generation capacity, with some £15 billion earmarked for the UK by 2030. This energy transition will support the UK on its journey to net zero and help to support lower energy prices in the longer term.

RWE is the UK’s largest operator of Combined Cycle Gas Turbine (CCGT) power plants with a fleet of around 7GW installed capacity providing security for the country’s energy supply. The company is driving an accelerated pace of transition as we assess CCUS and hydrogen combustion options to decarbonise our sites. In addition to upgrading our existing fleet, we are looking at developing new, state-of-the-art CCGTs with carbon capture technology installed. Our target is for the first of our fleet to be converted to decarbonised operation before 2030.
