UK's new power station

Two brief things today, firstly Centrica have decided to build the UK's first major new power station in five years. Yes, you guessed it, the 885MW will be generated from combined cycle gas turbine. The power station and necessary infrastructure itself is quite cheap at only £400m, it's the gas that's expensive, running 24/7 (not that it would) on 2p/kWh (likely an underestimation) gas would cost £155m a year. I wonder what assumptions for gas and electricity prices the business case is built on?

Secondly, Deloite have produced an rather nice map of UK power stations. The 1.4MB pdf is available here or click the map to open in a new window.
