(Sharecast News) - Energy firm Centrica will take a 15% stake in Britain's Sizewell C nuclear project, according to the Financial Times, following years of delays and extensive negotiations.

A final investment decision on the project was being targeted for before parliament's recess on 21 July.

Sizewell's final cost could be close to £40.0bn, the Financial Times reported in January, although management has rejected that figure.

Centrica's planned investment means that the FTSE 100-listed company will have the same size stake in Sizewell C as French state-owned energy group EDF.
