Virtual PPA with KDDI and Sales Under FIP Scheme
J-Wind has signed a virtual Power Purchase Agreement (PPA) with KDDI, under which the environmental value generated from the wind farm will be provided as non-fossil certificates (NCCs) for 20 years. With this PPA, KDDI expects to reduce CO2 emissions from its base stations in the Kyushu area by approximately 50%. The aim is to begin operations in December 2027.
The power sales scheme will incorporate a Feed-in-Premium (FIP) mechanism. J-POWER will handle demand-supply balancing operations, including the formulation and submission of power generation plans, as well as bearing imbalance costs. The generated electricity will be sold on the Japan Electric Power eXchange (JEPX). The aim is to begin operations in December 2027.
