A number of multimillion-pound contracts on the £18bn Hinkley Point C nuclear power plant are being renegotiated, Building understands. EDF said last week it will make a final investment decision on the power plant in Somerset “within weeks”, after it secured £6bn of investment from China General Nuclear Corporation (CGN). The French energy giant also announced it had agreed final terms on five major contracts with suppliers. However, sources have told Building that while a final investment decision is now expected to be “a formality”, several major contracts agreed over the last three years are currently being renegotiated due to cost inflation. These contract values include those where final terms have been agreed, sources said. One source told Building: “There’s a lot of to-ing and fro-ing with contracts at the moment. Discussions are happening all the time. “Also, a lot of contracts were originally negotiated during the recession. Now firms are finding that they don’t necessarily need the work.” The news comes after a Kier and Bam joint venture announced last week it had signed a new contract for the enabling works worth £203m, more than double the widely reported figure of £100m when the contractors were selected in 2012.
