Dungeness B is situated near Romney Marsh, Kent on the south east coast of England.

Dungeness B is a twin reactor advanced gas-cooled (AGR) station. It was the first commercial advanced gas-cooled reactor to commence construction (1965) and started generating power in 1983.

End of generation is currently estimated by EDF Energy to be in 2028. The power station is built on a large area of open shingle, measuring 12 km by 6km. The three small towns on the headland nearest the power station are Lydd-on-Sea, Greatstone-on-Sea and Littlestone-on-Sea, which lie to the north on the east coast of the Dungeness headland.

Dungeness B produces enough energy for over 1.5 million homes and employs 550 permanent full-time staff and over 200 contractors.

Dungeness B is operated by the licence holder EDF Energy Nuclear Generation Ltd, a subsidiary company of EDF Energy plc.
