On November 27, 2018, Tokyo Electric Power Company Holdings (TEPCO) announced that it will launch its first commercial offshore wind power facility on January 1, 2019. TEPCO has been conducting an offshore wind power facility demonstration project in the south of Choshi City, Chiba Prefecture. The facility is equipped with a bottom-fixed foundation turbine with a rated output of 2,400 kW. The demonstration project confirmed that the facility can be operated safely at a high capacity factor under harsh weather and marine conditions.

TEPCO aims to expand its renewable energy businesses in order to ensure a stable electricity supply. TEPCO’s ultimate goal is to increase its domestic output of offshore wind power to 2-3 GW. In order to achieve this goal, on November 1, 2018 TEPCO initiated a seabed survey off the coast of Choshi City to examine the feasibility of building an additional offshore wind farm in the area.
