The Hinkley Point C (HPC) nuclear power plant will cost UK consumers as much as £21 billion over the lifetime of the project.
EDF has negotiated a strike price of £92.50/MWh for the electricity it generates for 35 years with the UK Government under its Contracts for Difference (CfD) scheme.
The final agreement was signed by the French utility, the UK Government and China’s CGN.
According to the government, the total cost over the whole CfD has been estimated at £11 billion to £21 billion. Its “most realistic projections” mean around £12 from energy bills will go towards supporting the plant in 2030.
There have however been concerns about the strike price being too high.
The government states: “It is not just HPC which will receive support from consumer bills; other clean technologies such as offshore wind receive the same kind of support. These payments are only one part of a consumer’s electricity bill and only partially reflective of the costs of decarbonisation.
“For example, if HPC is delayed by three years and offshore wind and carbon capture and storage (CCS) are needed to fill the gap, it would lead to a £24 annual increase on household electricity bills on average from 2026 to 2030 (2012 prices). Similarly, if onshore wind and large-scale solar PV were to fill the gap, consumer bills would increase annually by £21. Gas plant coming on to fill the gap would see bills £6 cheaper per year but this would undermine the UK’s ability to meet legally binding decarbonisation targets.”
HPC is expected to provide 7% of the nation’s power needs and create 26,000 jobs and apprenticeships.
