This Damhead Creek 2 power station will be built adjacent to the company’s existing 800MW Damhead Creek gas-fired power plant.

The new combined-cycle gas turbine plant is expected to generate enough electricity to supply almost 1.5 million homes.

British energy minister Charles Hendry said that the new power plant will play a vital role in providing secure electricity supplies for the south-east of England, as well as creating jobs in the region.

"It will be one of the most efficient power plants in the world, and be built carbon capture ready, which means that eventually CO2 produced by the plant could be captured and transported for storage under the North Sea," Hendry said.
