Site information

Site profile

Sizewell A site, located on the Suffolk heritage coast ended 40 years of safe, compliant electrical generation on 31 December 2006. A number of enabling projects are currently taking place as part of the site's Defuelling and Decommissioning preparations.

During the station’s operational lifetime its twin Magnox reactors produced over 110 TWh of electricity. This is enough to continually supply England and Wales for six months. A typical day’s generation saw the station supply more than 10 million kWh of electricity:- enough to serve the demand of a third of East Anglia.

Immediately to the north of Sizewell A is Britain’s newest nuclear power station Sizewell B, which is operated by British Energy.
