Sizewell C Power Station: Compensation
The question
To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answer of 16 October 2024 to Question 7946 on Sizewell C Power Station: Compensation, what (a) output in MWh his Department has assumed for Hinkley Point C and (b) discounting rate has been applied for sharing First-of-a-Kind costs with Hinkley Point C over the first 35 years of its lifetime; and whether the cost of the discounting rate is included in expenditure eligible for a Sizewell C Regulated Asset Base.
Answered by Michael Shanks
EDF’s assumed maximum capacity of HPC is 3.2GW, overlaid with assumptions for planned and unplanned outages. There isn’t a specific discounting rate applied to the First-of-a-Kind cost sharing. Instead, the payment for this cost sharing is included in the forecast expenditure eligible for the SZC RAB, along with other eligible project costs; and the consumer costs, driven by the RAB, are discounted at the applicable Social Discount Rate used in the Government’s Value for Money assessment of the SZC project.
