Didcot B Power Station

Didcot B is one of a new generation of highly efficient, gas-burning power stations, which has been in commercial operation since 1997. The station is powered by natural gas and uses the latest generating technology (combined cycle gas turbines - CCGT) to produce electricity.

Didcot B can produce 1,360MW, enough power to meet the needs of 1 million households.

CCGT power stations are more efficient than conventional power stations as they make double use of the heat produced by burning natural gas: firstly in gas turbines, secondly because the waste heat from the gas turbines is used to raise steam to drive the steam turbine generators.

Strict operational controls ensure that our emissions are within regulatory limits set to minimise our environmental impact. We have completed a £60 million project to replace two of our gas turbines with the latest technology, which has increased the station’s efficiency to over 55%, one of the highest in the UK. This will also result in the station emitting less CO₂ per unit of electricity we produce.
