While Hinkley Point C is not set to start generating electricity before June 2027, two years behind schedule, there is still plenty going on.
The camera goes several miles under the seabed to see the final stages in the completion of the cooling water intakes. It also shows work on the 50-metre tall turbine hall, which will house the world’s largest Arabelle turbine.
Work to fit the miles of cables, pipes and equipment is also well under way.
Hinkley Point C is being developed by EDF of France with China General Nuclear as its junior partner.
On completion, the two 1600 MWe nuclear reactors of Hinkley Point C are expected to generate enough electricity to power six million homes.
