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

Cosmo Eco Power Co., Ltd. (Head Office: Shinagawa-ku, Tokyo; President: Fumiaki Nokura; hereinafter "Cosmo Eco Power"), a group company of Cosmo Energy Holdings Co., Ltd. (Representative Director and President: Shigeru Yamada), and Cosmo Energy Solutions Co., Ltd. (Head Office: Chuo-ku, Tokyo; President: Yasuyuki Kawamura; hereinafter "Cosmo Energy Solutions"), along with Tokyo Metro Co., Ltd. (Head Office: Taito-ku, Tokyo; President: Akihiro Kosaka; hereinafter "Tokyo Metro"), have signed an off-site physical PPA*1 (Power Purchase Agreement; hereinafter "this Agreement") for Tokyo Metro's General Training Center, the first of its kind for a subway, utilizing a combination of onshore wind and agrivoltaic power sources. Electricity supply under this Agreement will commence in April 2026, and is expected to result in an annual CO₂ reduction of approximately 719 tons, equivalent to the annual electricity consumption of Tokyo Metro's "General Training Center." This Agreement combines wind power from Cosmo Eco Power's own Aizu Wakamatsu Wind Farm with agrivoltaic power sourced from Eneglobal Co., Ltd.'s facilities, with Cosmo Eco Power acting as an aggregator*2. The electricity generated from these sources will be supplied to Tokyo Metro's "General Training Center" through Cosmo Energy Solutions, a retail electricity provider. This scheme aims to improve the hourly matching ratio*3 by combining wind and solar power. Furthermore, during periods when wind and solar power cannot cover demand, electricity derived from the market will be supplied in combination 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 generation, towards achieving "Carbon Net Zero by 2050." Moving forward, they will continue to strengthen collaboration 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 a 53% reduction in CO₂ emissions from all Tokyo Metro Group operations by FY2030 (compared to FY2013) and virtually zero by FY2050. To date, Tokyo Metro has introduced energy-efficient rolling stock and environmentally friendly facilities. Moving forward, it will continue to contribute to the realization of a "decarbonized and circular society" by utilizing various means, including the use of renewable energy, to achieve its goals. Location: Koto-ku, Tokyo Facility Overview: Training line (total length approx. 700m, 3 simulated stations), Training building (5 stories above ground) *Related site: https://www.tokyometro.jp/news/2016/844.html Power Plant Overview Location: Aizuwakamatsu City, Fukushima Prefecture Capacity: 16,000kW Power Plant Overview Location: Naka City, Ibaraki Prefecture Capacity: DC1,155 / AC792kW *1 Off-site physical PPA: A contract model where a consumer procures electricity and environmental value from a renewable energy power plant installed outside their own premises. *2 Aggregator: An operator that bundles and manages multiple distributed power sources and demands to efficiently and stably supply electricity and adjust supply-demand. *3 Hourly matching ratio: An indicator showing the percentage of electricity consumption that matches renewable energy generation on an hourly basis. It is being considered in international discussions for revising the GHG Protocol from the perspective of enhancing the effectiveness of decarbonization.
