Cosmo Eco Power Co., Ltd. (hereafter, “Cosmo Eco Power”), a subsidiary of Cosmo Energy Holdings Co., Ltd., and JAPAN BENEX CORPORATION (hereafter, “JAPAN BENEX”) are pleased to announce that they have entered into a physical Power Purchase Agreement (PPA) covering rooftop solar power generation systems certified under Japan's Feed-in Premium (FIP) scheme¹ (hereafter, “the Agreement”)².
This initiative leverages an aggregation service provided by Cosmo Eco Power. By making effective use of the rooftops of distribution facilities and other buildings while aggregating and managing distributed power sources, the effort will support the expanded use of renewable energy-derived electricity.
Based on the Agreement, Cosmo Eco Power will receive renewable energy over a 20-year period from two FIP-certified rooftop solar power generation systems (total capacity: approximately 5.5 megawatts (MW)) owned and operated by JAPAN BENEX in Kanagawa and Hyogo prefectures. As an aggregator³, Cosmo Eco Power will supply this renewable energy to its group company, Cosmo Energy Solutions Co., Ltd. (hereafter “Cosmo Energy Solutions”), which will in turn sell it to consumers as an electricity retailer.

The Cosmo Energy Group and JAPAN BENEX have concluded the Agreement with the goal of fulfilling their social responsibility to help realize a carbon-neutral society by contributing to the uptake of renewable energy. Going forward, the two parties remain committed to driving initiatives to reduce their environmental impact and build a sustainable society.

Overview of the Cosmo Energy Group's Efforts to Achieve Carbon Neutrality
As a member of the Cosmo Energy Group, Cosmo Eco Power is striving to achieve net zero carbon emissions by 2050. With the country transitioning from the Feed-in Tariff (FIT) scheme⁴ to the FIP scheme for renewable energy, the expertise gained from this initiative is expected to be applied to the development and operation of future offshore and onshore wind power plants in which Cosmo Eco Power hopes to be involved, thereby contributing to the establishment of renewable energy as Japan’s main power source.
Initiatives Undertaken by JAPAN BENEX
Established in 1957, JAPAN BENEX has leveraged its 67 years of expertise in precision sheet metal fabrication to expand into the renewable energy sector since 2012. It now owns solar power generation systems with a total capacity of approximately 63.6 megawatts (MW) nationwide, with a particular focus on rooftop mega-solar installations on distribution facility rooftops. Through the construction and operation of these solar power generation systems, JAPAN BENEX is contributing to the realization of a decarbonized society.
1. Feed-in Premium (FIP) scheme: A program established in April 2022 to further promote renewable energy adoption and establish it Japan’s main power source. Under this scheme, power producers receive a premium on top of the revenue earned from selling electricity. Unlike the FIT scheme, where electricity generated at power plants is purchased by electric power companies, the FIP scheme allows power producers to choose their buyers, including sales to the wholesale electricity market or direct transactions with consumers via corporate PPAs, etc.
2. A physical PPA is a type of corporate PPA whereby consumers purchase renewable energy directly from power producers. Under physical PPAs, power producers supply consumers with both the physical electricity and the associated environmental value.
3. An aggregator optimizes electricity supply and demand by leveraging diverse energy resources and managing market transactions. By bundling distributed energy resources (DERs), aggregators help balance supply and demand, thereby maximizing the utilization of available energy resources.
4. Feed-in Tariff (FIT) scheme: Under this program, which was enacted in 2012 with the goal of promoting the adoption of renewable energy, the Japanese government guarantees that electric power companies can purchase electricity generated from renewable energy sources at a fixed price for a certain period.
