How Seabank Power Ltd compares

9th of 49largest gas-fired stations in the UK register
1st of 4in South West
3.8%of listed UK gas-fired capacity

Gas-fired power stations burn natural gas. Combined-cycle gas turbine (CCGT) plants reuse exhaust heat to raise steam for a second turbine, making them more efficient than single-cycle (open-cycle) gas turbines, which are used mainly for short peaks in demand.
