NEC Corporation has signed a virtual Power Purchase Agreement (vPPA) with Cosmo Eco Power for the environmental value from the 48.3MW Chuki Wind Farm in Wakayama Prefecture, Japan. The vPPA has been effective since December 25, 2024, enabling NEC to cover approximately 50% of its electricity consumption from its Japanese data centers with renewable energy. The Chuki Wind Farm began commercial operations in April 2021 and continues to supply power to the Japanese electricity market, with NEC purchasing only the environmental benefits generated.
