On September 20, 2018, TEPCO Innovation & Investments US, Tokyo Electric Power Company’s wholly owned subsidiary in the U.S., announced that it has invested two million USD in Adon Group, a Hawaiian renewable energy company. Adon Group, which consists of Adon Construction, Adon Renewables, and Green Vision, specializes in the development, construction, operation, maintenance, and asset management of solar facilities, mainly for commercial and industrial (C&I) customers in Hawaii. Through its investment in Adon Group, TEPCO Innovation & Investments US aims to join the Hawaii C&I solar energy market and develop new business models, including microgrid and resource aggregation businesses.

Hawaii has set a goal to generate 100% of its electricity from renewable energy by 2045. The implementation of solar photovoltaic (PV) systems has been increasing in Hawaii due to their affordable price and support from federal and state government subsidies. However, as the solar generation capacity increases, it is facing issues such as supply-demand balancing and system-voltage control. Hawaii has been focusing on PV systems equipped with battery storage to address these challenges. Adon Group plans to expand its businesses by offering PV systems equipped with battery storage.
