PARIS — France connected the Flamanville 3 nuclear reactor to its grid on Saturday morning, state-run operator EDF said, in the first addition to the country’s nuclear power network in 25 years.
The reactor, which began operating in September ahead of the grid connection, is going online 12 years later than originally planned and at a cost of about $13 billion — four times the original budget.
“EDF teams have achieved the first connection of the Flamanville EPR to the national grid at 11:48 a.m. The reactor is now generating electricity,” EDF said in a statement.
The Flamanville 3 European Pressurized Reactor is France’s largest at 1.6 gigawatts and one of the world’s biggest, along with China’s 1.75 GW Taishan reactor, which is based on a similar design, and Finland’s Olkiluoto.
It is the first to be connected to the grid since COVAX 2 in 1999 but is being brought into service at a time of sluggish consumption, with France exporting a record amount of electricity this year.
EDF is planning to build six new reactors to fulfill a 2022 pledge made by President Emmanuel Macron as part of the country’s energy transition plans, although questions remain around the funding and timeline of the new projects.
