Tokyo Gas Co will install 19 offshore wind turbines that could generate a maximum of 159.6 megawatts near the coast of Ibaraki Prefecture, eastern Japan from 2024 as the government moves towards carbon neutrality by 2050.
The 680-hectare wind farm could supply 70,000 households annually.
The project would be funded by Wind Power Group Co, based in Ibaraki Prefecture, and Vena Energy Holdings Ltd, a renewable energy company in Singapore. The start date has yet to be decided.
Tokyo Gas aims to lead renewable energy growth to contribute to the realization of a sustainable society, says its president, Takashi Uchida.
He added that Tokyo Gas is committed to a stable power supply by balancing output fluctuation in power generated by renewable energy with gas-fired power generation.
The government of Japan has set a goal of raising its offshore wind power generation to up to 45 gigawatts in 2040 from a mere 20,000 kilowatts at present.
