Tokyo Metro Introduces Physical PPA at General Training Center: Hourly Matching Scheme Combining Onshore Wind and Agri-Photovoltaic Power Sources

Cosmo Eco Power Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; President and CEO: Fumiaki Nogura; hereinafter "Cosmo Eco Power"), a group company of Cosmo Energy Holdings Co., Ltd. (President and CEO: Shigeru Yamada), and Cosmo Energy Solutions Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President and CEO: Yasuyuki Kawamura; hereinafter "Cosmo Energy Solutions"), along with Tokyo Metro Co., Ltd. (Headquarters: Taito-ku, Tokyo; President and CEO: Akihiro Kosaka; hereinafter "Tokyo Metro"), have concluded an off-site physical PPA*1 (Power Purchase Agreement; hereinafter "this Agreement") for the first time for a subway's general training center, utilizing a combination of onshore wind and agri-photovoltaic power sources. Electricity supply based on this Agreement will commence in April 2026, and an annual CO₂ reduction effect of approximately 719 tons, equivalent to the annual electricity consumption of Tokyo Metro's "General Training Center," is anticipated. Under this Agreement, Cosmo Eco Power combines wind power from its own Aizu Wakamatsu Wind Farm with agri-photovoltaic power sourced as an aggregator*2 from EnerGlobal Co., Ltd. These power sources will supply electricity to Tokyo Metro's "General Training Center" through Cosmo Energy Solutions, a retail electricity provider. This scheme aims to improve the hourly matching rate*3 by combining wind and solar power. Furthermore, during hours when wind and solar power cannot cover the demand, electricity derived from the market will be supplied, combined with non-fossil value derived from renewable energy sources operated and contracted by Cosmo Eco Power. Cosmo Eco Power and Cosmo Energy Solutions, as members of the Cosmo Energy Group, are committed to developing and expanding the supply of renewable energy, including wind power, towards achieving "Carbon Net Zero by 2050." Moving forward, they will continue to strengthen cooperation with demand-side customers promoting decarbonization, contributing to the widespread adoption of renewable energy and the development of local communities. Tokyo Metro has set a long-term environmental target, "Metro CO₂ Zero Challenge 2050," aiming for "-53% by FY2030 (compared to FY2013) and virtually zero by FY2050" for the total CO₂ emissions from all Tokyo Metro Group businesses. Until now, the company has introduced energy-efficient rolling stock and environmentally friendly facilities. Moving forward, to achieve its goals, Tokyo Metro will continue to contribute to the realization of a "decarbonized and circular society" by utilizing various means, including the active use of renewable energy.
