EDF Energy chief executive Vincent de Rivaz has pledged that Hinkley Point C will be delivered on time and on budget.
The long awaited final investment decision to build the £16bn nuclear power plant in Somerset has still to be made.
De Rivaz admitted at an event in Kent this week that EDF had taken longer than it expected to give the go ahead.
But he insisted the scheme – the first in an anticipated wave of new nuclear projects – would be built successfully.
“People have said that because Hinkley Point won’t come on line when we originally said it would, it is too late,” he said.
“In fact Hinkley Point will come in time. Not too early, not too late. When it arrives it will be welcome and it will be needed.
“But we don’t have the luxury of waiting. In a few short years, Britain will need Hinkley Point C, and we are on track to deliver for when it does.
“I acknowledge that we will have taken longer than we originally thought. But in the scale of this investment – 60 years of operation – we have to focus on the main points:
“Will it be there when the country needs it? Yes it will. Will it be on cost and on schedule? Yes it will. Will it be safe in construction and operation? Yes it will.”
EDF this summer announced preferred bidders for more than £1bn of sub contracts including electrical, mechanical and transmission deals.
