Hinkley Point C Nuclear Plant Faces Delays and Rising Costs

Hinkley Point C, Britain’s first new nuclear power plant in a generation, is now set to begin operations in 2030, a year later than previously planned. The project, located in Somerset, has faced multiple delays since construction commenced nearly 13 years ago. The latest postponement will cost the French utility company EDF an additional €2.5 billion, raising the total estimated cost of the plant to £35 billion—almost double the initial estimate of £18 billion from 2016. This figure does not account for inflation, which will further increase the final costs.

The delay at Hinkley Point C is expected to significantly impact EDF’s financial performance, contributing to a projected loss of nearly £3 billion. The company’s chief executive, Bernard Fontana, described the new cost forecasts as “more realistic,” indicating that the timeline for operations has remained consistent since 2024, when the company anticipated a startup window between 2029 and 2031. Once operational, Hinkley Point C is expected to supply approximately 7% of Britain’s electricity demand.

Hinkley Point C is part of the UK government's strategy to reduce reliance on fossil fuels and meet legally binding climate targets. However, the project has faced criticism for its escalating costs and delays. EDF's other nuclear project, Flamanville in France, serves as a cautionary tale, having experienced a 12-year delay with costs soaring from an initial €3.3 billion to over €13.2 billion. In addition to Hinkley Point C, EDF is also preparing to construct six new reactors in France and complete the Sizewell C project in Suffolk, where it holds a 12.5% stake.

The financial strain from Hinkley Point C is compounded by a decline in EDF's overall earnings, which fell from €36 billion in the previous year to just over €29 billion in 2025. This decline is attributed to reduced electricity generation across the UK, France, and Italy, alongside lower wholesale market prices. Specifically, EDF's earnings from UK electricity generation dropped by a third to €2.3 billion, influenced by unplanned outages and an increased maintenance schedule.

Critics of the Hinkley Point C project highlight the ongoing issues of cost overruns and delays, questioning the viability of nuclear energy as a solution to the UK's energy needs. The reliance on government contracts to stabilize prices for electricity generated at the plant has also raised concerns among energy bill payers, who are expected to contribute over £2 billion annually in subsidies once the plant becomes operational.
