More Nuclear Overruns: Assessing the Impact of Hinkley Point C's Slow and Expensive Build

Report Summary:

EDF has announced a major delay of its Hinkley Point C nuclear power plant in the UK - this is the fifth such warning it has given since taking FID on the 3.3 GW new-build project in 2016. Commissioning of the first reactor could now slip into the 2030s, five years beyond its original timeline. The material impacts of this latest overrun are not restricted to the GB power market, and resonate across surrounding systems, with implications for supply mix, prices and cross-border flows.
