AT TOKYO Corporation Signs Virtual PPA Agreement with ML Power Company Limited to Expand Renewable Energy Use

In a move to accelerate renewable energy adoption in data center operations, AT TOKYO Corporation has entered into a basic agreement on a Virtual Power Purchase Agreement (VPPA) with ML Power Company Limited, a subsidiary of Mizuho Leasing Company Limited.

The agreement, concluded on March 17, 2026, involves transitioning an approximately 28 MWdc solar power plant—operated by a Mizuho Leasing subsidiary—from Japan’s Feed-In Tariff (FIT) scheme to the Feed-In Premium (FIP) scheme. This shift enables ML Power to supply AT TOKYO with Non-FIT Non-Fossil Certificates, allowing the company to utilise renewable energy attributes without direct electricity procurement.

The initiative is aimed at increasing the share of renewable energy used in AT TOKYO’s data centers, which are known for their high electricity consumption. By leveraging a Virtual PPA structure, the company seeks to reduce its carbon footprint while maintaining flexibility in energy sourcing.

Under Japan’s FIP scheme, renewable energy is sold in the electricity market with a premium, replacing the earlier fixed-price FIT model. This transition is expected to enhance market integration of renewable energy and support more dynamic procurement mechanisms such as VPPAs.

Mizuho Leasing and ML Power stated that the agreement aligns with their broader strategy to contribute to a decarbonised society. The companies aim to expand the supply of Non-FIT Non-Fossil Certificates and promote flexible renewable energy solutions in response to evolving regulatory and market conditions.

The collaboration reflects a growing trend among data center operators to adopt innovative procurement models to meet sustainability targets, while supporting the broader transition towards carbon neutrality in Japan’s energy sector.
