Hinkley Point C Unit 1 Now Targeted for 2030
EDF has pushed the first reactor at Britain's Hinkley Point C nuclear plant back to 2030 and raised its cost estimate to roughly £35bn in 2015 prices.
- EDF's 2025 accounts, reported on 20 February 2026, put Hinkley Point C Unit 1 power-up in 2030, its base case, and the cost at GBP35bn in 2015 prices, nearly double the initial GBP18bn[3]
- This updates a January 2024 announcement that unit 1 was unlikely before 2030 at GBP31-34bn, which itself replaced 2027 and up to GBP26bn; 2029 was the best case and 2031 the worst[2][3]
- A further 12-month delay would add around GBP1bn[2][3]
- Causes cited include COVID-19 (a 15-month delay), Brexit, Ukraine, adapting the EPR design to UK regulation, difficult ground and electromechanical work issues[2][3]
- Hinkley Point C has two 1630 MWe EPR reactors, construction began December 2018, and since end-2023 has been financed by EDF equity, with CGN's stake down to 23.31%[2][3]
- The B1M video 'Overbudget: Britain's $57BN Nuclear Nightmare' (January 2025) covers the cost overruns; only its description and chapters were available[1]
Cost £35B (≈$44.9B)
