The Hinkley Point C nuclear power station will likely be 15 months late and £1.5billion over estimated budget.
But the revised cost estimates and a delayed delivery will not have any impact on the contract signed by French utility EDF (EDF.PA) and the British government, the company said on Monday.
The French state-controlled utility raised its estimate for the costs involved with its Hinkley Point C and said the risk of a deferral in the delivery (COD) of the project was estimated at 15 months for Unit 1.
EDF energy director Vincent de Rivaz said that following discussions with the British government, the new cost estimates and delivery delay will have no impact on the Hinkley Point contract signed between the company, the UK government and partners.
