Equinix has signed a 15-year virtual power purchase agreement with ENEOS Renewable Energy Corporation for 121MW of solar capacity from the Sanda Mega Solar Power Plant in Hyogo Prefecture.

The deal is the largest single-site data center vPPA signed in Japan and marks Equinix’s second power purchase agreement in the country. It is structured to expand renewable coverage for the company’s Japanese operations while supporting growth in AI-driven digital infrastructure.

Strengthening Renewable Coverage in a Constrained Market

Japan remains a complex market for corporate renewable procurement, with grid limitations, regulatory barriers and constrained land availability slowing clean energy deployment. By securing long-term offtake from one of the country’s largest operating solar projects, Equinix is addressing renewable supply constraints while improving energy resilience for its data center portfolio.

The agreement supports Equinix’s target of achieving 100% renewable energy coverage for its Japanese operations and responds to increasing customer demand for lower-carbon digital infrastructure.

Solar Development on Repurposed Land

The Sanda Mega Solar Power Plant was developed on a former golf course site while preserving surrounding forested areas. With 121MW of installed capacity, it is the largest solar facility in ENEOS Renewable Energy’s portfolio.

ENEOS Renewable Energy has developed close to 1GW of solar capacity across Japan, positioning it as a key supplier for long-term corporate procurement contracts in the region.

Supporting AI and Cloud Expansion

Data center electricity demand in Japan is rising alongside expansion in artificial intelligence and cloud computing services. Long-duration virtual PPAs provide operators with greater price stability and predictable supply, both critical as energy demand increases.

For Equinix, the agreement links digital infrastructure growth with renewable sourcing, allowing hyperscale and enterprise customers to align sustainability targets with operational requirements.

Market and Policy Implications

Corporate renewable procurement in Japan has historically trailed other major economies due to structural constraints. Long-term agreements such as this vPPA contribute additional renewable capacity to the grid while helping mature Japan’s corporate clean energy market.

As technology firms expand AI capacity across Asia, energy sourcing is becoming a strategic priority shaped by regulatory compliance, cost exposure and emissions commitments. Structured renewable contracts are increasingly central to balancing grid reliability, decarbonization objectives and infrastructure growth in constrained power markets.
