- Hinkley Point C in Somerset is under construction. When completed it will provide around 7 per cent of the UK’s electricity ( ~3.5 Gigawatts). It is set to be the most expensive nuclear power station ever built... more than 4 X more expensive than an average South Korean or Chinese nuclear power plant . A French plant that uses the same reactor (EPR-1750) and built by the same company (EDF), is set to cost 25 per cent less.
