British Energy bought the 2,000 MWe Eggborough coal fired station from National Power in 2000 to provide a more flexible power production facility and reduce penalty charge risks from the New Electricity Trading Arrangements introduced in March 2001. Despite this, the new arrangements led to a significantly lower electricity price for inflexible base load power stations such as British Energy had. The purchase of Eggborough occurred at the peak of the market for power stations, and in 2002 the value of the station was written down by half.
