We own and operate eight nuclear power stations with a combined capacity of almost 9,000 megawatts. We operate two types of nuclear reactor: the advanced gas-cooled reactor (AGR); and a pressurised water reactor (PWR). Sizewell B is the only PWR nuclear power station in our portfolio. Capacities are stated net of all power consumed for the stations' own use, including power imported from the National Grid. Capacities are subject to review each year end. The capacities quoted reflect expectations for the reference energy generation from the units from 1 January 2013. In particular, Hinkley Point B and Hunterston B have been adjusted to reflect planned operation at approximately 70% load, due to boiler temperature restrictions.
*Based on currently agreed accounting lives. One of EDF Energy's business imperatives is to extend the lifetimes of its nuclear power stations where it is technically and economically viable to do so safely.
