Cosmo Eco Power Co., Ltd., Cosmo Energy Solutions Co., Ltd. (both subsidiaries of Cosmo Energy Holdings Co., Ltd.), and Tokyo Metro Co., Ltd. have signed an off-site physical Power Purchase Agreement (PPA) combining onshore wind and agrivoltaic (solar) power sources for Tokyo Metro's Comprehensive Training Center, a first for a subway system.
Power supply under this agreement will commence in April 2026, with an expected CO2 reduction of approximately 719 tons annually, equivalent to the center's total annual power usage.
This agreement combines wind power from the Aizu-Wakamatsu Wind Farm operated by Cosmo Eco Power with agrivoltaic solar power owned by EneGlobal Co., Ltd., for which Cosmo Eco Power acts as an aggregator. The electricity generated from these sources will be supplied to Tokyo Metro's Comprehensive Training Center through Cosmo Energy Solutions, acting as the retail electricity provider. By combining wind and solar sources, this scheme aims to improve the hourly matching ratio. For time slots where wind and solar cannot meet the demand, electricity from market sources will be supplied in combination with non-fossil certificates derived from renewable energy sources operated or contracted by Cosmo Eco Power.
As part of the Cosmo Energy Group, Cosmo Eco Power and Cosmo Energy Solutions are committed to the development and expansion of renewable energy, including wind power, to achieve 'Carbon Net Zero by 2050'. They will continue to strengthen cooperation with consumers promoting decarbonization and contribute to the spread of renewable energy and regional development.
Tokyo Metro has set a long-term environmental goal, 'Metro CO2 Zero Challenge 2050', aiming for a 53% reduction in CO2 emissions across all Tokyo Metro Group operations by FY2030 (compared to FY2013) and achieving net zero by FY2050. The company has already introduced highly energy-efficient vehicles and low-environmental-impact facilities. To achieve its goals, Tokyo Metro will continue to contribute to a 'decarbonized, circular society' through various means, including the utilization of renewable energy.
