Conclusion of Basic Agreement on Virtual PPA Utilizing the FIP Scheme
Promoting Renewable Energy Use in Data Centers

AT TOKYO Corporation (Headquarters: Koto-ku, Tokyo; President & Chief Executive Officer: Tatsuya Izumida; hereinafter “AT TOKYO”), together with ML Power Company, Limited (Headquarters: Minato-ku, Tokyo; President & CEO: Nariaki Sakurai; hereinafter “ML Power”), a wholly owned subsidiary of Mizuho Leasing Company, Limited (Headquarters: Minato-ku, Tokyo; President & CEO: Akira Nakamura; hereinafter “Mizuho Leasing”), concluded a basic agreement on a Virtual Power Purchase Agreement (Virtual PPA)^*1 on March 17, 2026.

This initiative involves revising the contractual status of a solar power plant (approximately 28 MWdc), funded and operated by a consolidated subsidiary of Mizuho Leasing, from the Feed-In Tariff (FIT) scheme^*2, to the Feed-In Premium (FIP) scheme^*3. Through this transition, ML Power will supply AT TOKYO with Non‑FIT Non‑Fossil Certificates^*4, thereby promoting the use of renewable energy in AT TOKYO’s data centers.

As a data center operator that consumes significant amounts of electricity, AT TOKYO recognizes its social responsibility and will continue to actively expand the use of renewable energy, aiming to contribute to the fulfillment of a decarbonized and sustainable society.

Mizuho Leasing and ML Power have adopted the vision of becoming a “Creator of a Sustainable Society” and have identified “Contributing to a Decarbonized Society” as one of their material priorities. Based on this materiality, they will contribute to the realization of a carbon‑neutral society through agile operations and business decisions that accurately respond to regulatory changes and market trends. Furthermore, they will continue to promote greater utilization of the FIP scheme and expand the supply of Non‑FIT Non‑Fossil Certificates to enhance flexibility in renewable energy procurement and support customers in achieving decarbonization.
