Hinkley Point C project cost

By Hinkley Point C media team | Posted May 12, 2016


The cost of the project is £18bn in nominal terms. We have stated this in public many times and this has not changed.

This £18bn includes and has always included a provision for risks and contingencies. If we deliver the project for less, the gain will be shared with customers as part of the CFD gain share mechanism. Customers would not bear the cost of any overruns.

The total equity the two shareholders are committed to provide if necessary includes 15% of additional capacity amounting to £2.7bn.

This does not mean that we anticipate any additional costs beyond £18 bn. It simply reflects normal, prudent good practice for any construction project to know that the money would be available in the case of more extreme scenarios.

We don’t expect to use the additional 15% because we expect that Hinkley Point C will be on time and on budget at £18bn.
