Edf Energy

Campaign group Stop Sizewell claimed the Office for Nuclear Regulation failed to include sea defences in its considerations when issuing a nuclear site licence.

The existing nuclear site will cease production in 2024, but the Government has named Hartlepool a 'designated nuclear site' in its energy strategy.

The company behind Sizewell B power station, EDF Energy, is considering running it until 2055 - at least 20 years longer than originally planned.
