EDF-owned Hinkley Point C nuclear power plant has been granted final consent by the British Office for Nuclear Regulation.

The consent granted on Monday means the UK is on course to build its first nuclear power plant in two decades.

The Office for Nuclear Regulation (ONR) said the consent for the $23bn plant was a regulatory milestone and covered the placement of the concrete for the first safety-related structure at the plant, which is due to start producing power around 2025.

EDF is building the plant in southwest England with China General Nuclear Power Corporation (CGN), which has a 33.5 percent stake. It is expected to generate 3.2 GW of electricity, enough to meet about 7 percent of Britain’s demand.
