While Hinkley Nuclear Was Being Built, The UK Grid Decarbonized - CleanTechnica

The article discusses the prolonged and costly development of the Hinkley Point C nuclear power plant in the UK, highlighting how its construction timeline and budget have significantly expanded since the project’s inception. Initially approved in 2016 with an expected cost of £18 billion and a 2025 operational date, the project now faces a revised cost estimate of approximately £35 billion (in 2015 pounds) and a delayed start date around 2030. These overruns exemplify a common pattern in large infrastructure projects, characterized by budget inflation, schedule delays, and under-delivery of benefits. The article traces the origins of Hinkley Point C back to the mid-2000s when the UK’s electricity grid was heavily reliant on coal and gas, with nuclear power providing a smaller share. At that time, replacing retiring coal and aging nuclear plants with new large-scale nuclear reactors seemed a logical strategy to maintain grid reliability and reduce emissions.
