There is an air-cooled condenser to eliminate the need for cooling water. It makes use of a grey water supply provided by
Anglian Water ’s nearby sewage treatment plant. This grey water prevents the use of clean potable water from the city's supply and reduces the unnecessary use of chemicals to regenerate the ion exchange resins which are used to demineralise the water to protect the power station's boilers and steam turbine.References
