The initial budget for Hinkley Point C was £16B. With the latest cost overrun announcement, the price is now expected to come in around £26B, as operations have been pushed back to 2027 at the earliest. And that's for a minimum strike price of £106/MWh in 2021 (the contract strike price is indexed to inflation). In comparison, the strike price from wind can be as low as £40/MWh.

Under the amended terms of the contract, delivery could be pushed back as far as 2036.

The project is in little better shape than the EDF projects at Taishan, Flamanville or Olkiluoto.
