NEC Secures Major Renewable Energy Deal with 48.3MW Virtual PPA in Japan

NEC Advances Sustainability Goals with Landmark Wind Power Agreement

January 29, 2026

In a significant move for Japan's corporate renewable energy procurement, NEC Corporation has entered a virtual Power Purchase Agreement (vPPA) for 48.3 megawatts of wind power, marking a major step in the IT giant's decarbonization strategy. As global data center operators face increasing pressure to reduce their carbon footprint, such agreements are becoming crucial for securing clean energy and meeting ambitious environmental, social, and governance (ESG) targets.

The Japanese technology firm announced it has signed the agreement with Cosmo Eco Power, a wind farm developer and subsidiary of the Cosmo Energy Group. The vPPA, which took effect on December 25, 2025, grants NEC the environmental attributes from the 48.3MW Chuki Wind Farm, an onshore facility in Wakayama Prefecture that began commercial operations in April 2021. Under this financial arrangement, the physical electricity will continue to flow into the Japanese grid, while NEC secures the renewable energy certificates associated with the wind farm's output.

This transaction is substantial in scale for the Japanese market. NEC stated that the agreement will cover approximately 50 percent of the electricity consumption from its entire data center portfolio in Japan. The company operates a significant national footprint, including three core cloud data centers in Kobe, Kanagawa, and Inzai, alongside facilities in Nagoya, Ehime, Fukuoka, Sapporo, Hiroshima, and Tokyo. Furthermore, through a joint venture with system integrator SCSK, part of the Sumitomo Corporation conglomerate, NEC is connected to an additional network of 10 data centers spanning 95,000 square meters.

The deal underscores a growing trend where major technology and data center operators are leveraging virtual PPAs to overcome geographical and infrastructural barriers to direct renewable energy access. For NEC, this move directly supports its corporate sustainability objectives and mitigates exposure to volatile fossil fuel markets. For the broader Asia-Pacific data center industry, it sets a precedent for large-scale, sophisticated renewable energy procurement, potentially accelerating the region's transition toward a greener digital infrastructure as demand for computing power continues to surge.
