Marubeni Power Retail Corporation and Keio Corporation Conclude Off-site Corporate PPA

Keio Corporation (Headquarters: Tama City, Tokyo; President: Tomofumi Tsumura; hereinafter "Keio Corporation") and Marubeni Power Retail Corporation (President: Atsushi Suzuki; hereinafter "Marubeni Power Retail"), a consolidated subsidiary of Marubeni Corporation, have concluded a comprehensive off-site corporate PPA*1 (hereinafter "this agreement") for the supply of renewable energy electricity derived from a dedicated solar power plant for Keio Corporation.

Under this initiative, starting from April 2026, Marubeni Power Retail will begin supplying renewable energy electricity from solar power facilities to the "Keio Department Store Shinjuku Building," "Keio Shinjuku Oiwake Building," and "Keio FRENTE Shinjuku 3-chome Building" (hereinafter "target locations"). By also attaching non-fossil certificates with tracking*2 to the shortfall of electricity, it will be possible to substantially reduce the approximately 8,000 t-CO₂ emitted annually from electricity usage at the target locations.

The Keio Group has set a long-term environmental goal of achieving carbon neutrality by fiscal year 2050 and has been working to reduce CO₂ emissions by switching the electricity used at major hotels and commercial facilities in Tokyo to electricity derived from substantially renewable energy. Going forward, we will continue to promote initiatives for the realization of a decarbonized society, such as the steady promotion of energy-saving measures and consideration of the use of renewable energy-derived electricity.

In line with the Mid-Term Management Strategy "GC2027" of its parent company, Marubeni Corporation, Marubeni Power Retail will promote "Green Initiatives" and contribute to the realization of a decarbonized and sustainable society through off-site corporate PPAs.

We aim to supply approximately 5 million kW of renewable energy electricity to a wide range of customers by fiscal year 2030.

*1 Off-site Corporate PPA: A Corporate PPA (Power Purchase Agreement) is a contract in which a company purchases renewable energy from a power producer over a long period at a fixed price. It is attracting attention as an energy procurement method that can contribute to reducing corporate CO₂ emissions. The scheme of procuring electricity from a remote power generation facility via the general transmission and distribution network is called an "off-site corporate PPA."

*2 Non-fossil certificate with tracking: A certificate that proves the environmental value of non-fossil energy, with attribute information of the power plant (location, power source type, operation start date) attached.
