The power station originally had three generating sets, producing a total of 363 MW of electricity. The station underwent a £120 million refurbishment in 2001 which increased the generating power to 393 MW. One of the three 131 MW generators, Unit 15, was mothballed in 2013, and a year later the entire power station was closed. The station was subsequently sold and is undergoing conversion to Biomass.
