Cosmo Eco Power Co., Ltd. (hereafter, “Cosmo Eco Power” or “the Company”), a subsidiary of Cosmo Energy Holdings Co., Ltd., announces that it has entered into a virtual Power Purchase Agreement¹ (hereafter, “the PPA”) with NEC Corporation (hereafter, “NEC”), effective December 25, 2025.
Under the PPA, Cosmo Eco Power will provide NEC with the environmental value derived from wind power generated at the Chuki Wind Farm. The wind farm commenced commercial operations in April 2021 and, in partnership with the local community, has maximized the use of wind energy resources to generate sustainable green electricity.
In recent years, rapid advancements in AI technology and other factors have led to a steady increase in electricity demand at data centers. Accordingly, securing a stable and continuous supply of green electricity has become increasingly important.

With the conclusion of the PPA, together with NEC’s existing initiatives, it is expected that approximately 50% of the electricity consumed at NEC's data centers will now be covered by renewable energy.
As a member of the Cosmo Energy Group, Cosmo Eco Power aims to achieve net zero carbon emissions by 2050. Going forward, the Company remains committed to contributing to the wider adoption of renewable energy and to the development of local communities, together with consumers working toward the realization of a carbon-neutral society.
