Japan is preparing to restart the world’s largest nuclear power plant, Kashiwazaki-Kariwa, more than a decade after the 2011 Fukushima disaster forced a nationwide reactor shutdown.

Tokyo Electric Power Co. (TEPCO) plans to bring one of the plant’s seven reactors online Wednesday, with full operations eventually generating 8.2 gigawatts of electricity.

The move reflects Japan’s shift back to nuclear power to improve energy security and reduce reliance on imported fossil fuels amid delays in offshore wind projects.

Kashiwazaki-Kariwa is the 15th of 33 operable reactors to be restarted, following the complete shutdown of all 54 reactors after Fukushima, Al-Jazeera has reported.

The government is also promoting new reactor construction and recently announced state funding to accelerate its nuclear energy revival.
