Tokyo Electric Power Company Holdings Inc (TEPCO) and Ørsted A/S (a major power company based in Denmark) announced March 18, 2020, that they have formed a joint venture (JV) for an offshore wind power generation project off the coast of Choshi City, Chiba Prefecture, Japan.

The capital of the JV is ¥10 million. The investment ratios of TEPCO and Choshi Orsted HoldCo GK (a wholly-owned subsidiary of Ørsted) are 51% and 49%, respectively. Its headquarters are located in Chiyoda-ku, Tokyo.

TEPCO and Ørsted signed a memorandum of understanding (MOU) on the cooperation in offshore wind power generation in January 2019 and, since then, have been establishing a framework and system for the joint development of the project, "Choshi Offshore Wind Farm."

They will move forward with the development of the project in the aim of submitting a plan for exclusive use through an open call for proposals via the JV after the Japanese government designates the area off the coast of Choshi City as a promotion area.

In the project, wind power generation facilities that are anchored to the seabed and have a maximum output of 370MW will be built about 39km2 off the coast of Choshi City. It is expected that up to 72 5.2MW-, 62 6MW-, 47 8MW-, 39 9.5MW- or 31 12MW-class wind turbines will be set up. TEPCO and Ørsted aim to start operation of the facilities in fiscal 2024.

Thus far, TEPCO has installed wind power generation facilities with a rated output of 2.4MW off the coast of Choshi City. It conducted a demonstration test from January 2013 to March 2017 and started commercial operation in January 2019. Also, to verify the feasibility of the offshore wind farm, it has been engaged in a seabed survey since November 2018.
