Speaking exclusively to Utility Week (see interview) Greatrex said there is lots of speculation, partly because EDF has remained quiet about when it will make its final investment decision.
He added: “We are in an environment where there is a lot of attention and mischief making.
“It is the last chance for people to set out their concerns and objection to it.”
Despite the rumours surrounding the £18 billion project, Greatrex is confident it will proceed because of the time, effort and money the French energy giant has already invested.
“Lots of things have happened and if there was a serious suggestion EDF was just playing for time and was not committed to the project I don’t think we would have seen a lot of that going on.”
He said that this work included preparatory work at the site, as well as EDF’s creation of an office in Bristol and the agreement in principal with contractors and local suppliers.
“A lot of contracts are ready to sign so there isn’t a huge gap once the final decision has been made,” Greatrex added.
Last month, EDF held a board meeting which confirmed the significant recapitalisation of the company which will allow it to “proceed with its strategic investment programme – including Hinkley Point C.”
It has been reported that, off the back of this, the final investment decision on Hinkley Point is now due to be made in September.
