Hinkley Point C is being funded privately, based on a mechanism whereby the government guarantees EDF receive £92.50/MWh. This was thought of as expensive when the deal was being negotiated but the current wholesale price has been above that level for most of the past 12 months and is currently about £243/MWh. While EDF get the difference made up when the price is below the strike price, they pay back the difference if the wholesale price is higher.
