Cost of Sizewell C nuclear project expected to rise close to £40bn. Final price tag for building new power plant is likely to be double 2020 estimate. The final price tag for building the planned Sizewell C nuclear power station in Suffolk is likely to reach close to £40bn, according to people close to the negotiations over the flagship energy scheme. The sum is double the £20bn estimate given by developer EDF and the UK government for the project in 2020, reflecting surging construction costs as well as the implications of delays and cost overruns at sister site Hinkley Point C. The higher estimate is likely to raise questions over the government’s strategy for a nuclear power revival, at a time of stretched government finances and cost of living concerns. Earlier this month the Department for Energy Security and Net Zero (Desnz) said it could not reveal the current cost estimate for the project as it was “commercially sensitive”. But one senior government figure and two well-placed industry sources said that a reasonable assumption for the cost of building Sizewell C would be about £40bn in 2025 prices. Alison Downes, executive director of campaign group Stop Sizewell C, urged the government to “come clean” on the “massive true cost” of the project given that households would be paying upfront for its construction via a levy on energy bills. “This secrecy around Sizewell C is inexcusable.” Dale Vince, a big Labour party donor and founder of green energy company Ecotricity, has written to the government’s new Office for Value for Money warning that the construction of Sizewell “will saddle consumers with higher bills long before it delivers a single unit of electricity”. Speaking to the Financial Times, he added: “Nuclear is too expensive, too slow — and very expensive to contain at the end of its life.”
