JERA and Green Power Investment Corporation have begun commercial operations at the 112MW Ishikari Bay New Port Offshore Wind Farm in Japan.
Located 3 km off Hokkaido, the offshore wind farm features 14 8MW turbines made by Siemens Gamesa.
The partners own the Ishikari Bay New Port Offshore Wind Farm through special purpose company Green Power Ishikari GK.
Onshore construction was carried out by Kajima Corporation and offshore construction by a joint venture between Shimizu Corporation and Nippon Steel Engineering.
All electricity generated will be supplied to Hokkaido Electric Power Network (HEPN) after being routed through a project transformer substation which includes a 100MW battery storage capacity and then through HEPN’s Nishi Sapporo substation.
Bringing the project to completion was possible because of the “tremendous cooperation and understanding” extended by regional communities and government administrations including Hokkaido Prefecture, Ishikari City, and Otaru City during the project’s development and construction, JERA stated.
In May 2023 US-headquartered Pattern Energy concluded an agreement with JERA and NTT Anode Energy Corporation for the joint acquisition of Green Power Investment Corporation.
