Started Self-Consignment of Electric Power to MinebeaMitsumi Group Domestic Sites
Reduction of approximately 1,755t-CO2 a year using low-voltage solar power generation

(Utilizing RenetS which is jointly established by Mitsubishi HC Capital and Chuo Electric Power)

MinebeaMitsumi Inc. (Registered Head Office: Nagano, Representative Director, Chairman CEO: Yoshihisa Kainuma, hereinafter "MinebeaMitsumi") has started supplying electricity generated by solar power plants to MinebeaMitsumi and MITSUMI ELECTRIC CO., LTD. (hereinafter the "MinebeaMitsumi Group") through the "Jikotaku Support Service" which utilizes solar power plants (hereinafter the "Jikotaku Support" (self-consignment support)), provided by Godo Kaisha RenetS which is jointly established by Mitsubishi HC Capital Inc. and Chuo Electric Power Co., Ltd. From June to July 2023, the MinebeaMitsumi Group started to use electricity supplied by low-voltage solar power generation, which is non-FIT*1 and have high additionally*2, at five locations of the Group's offices and plants in the Kanto area. Moving forward, we will continue to reduce CO2 emissions.

Jikotaku Support provides comprehensive assistance to companies in proceeding smoothly with the self-consignment of solar power. It includes the development, maintenance and management of power plants, as well as handling of the various requirements and procedures for general power transmission and distribution companies to implement self-consignment, leasing contracts for power plants, and the prediction power volume generation and the submission of power generation plans. As well as requiring no initial investment from businesses for the development of power plants, the service enables them to directly procure stable renewable energy.

With Jikotaku Support, the MinebeaMitsumi Group will use approximately 2.7 million kWh of renewable energy from 27 low-voltage solar power plants with a low environmental impact (approximately 2.4 MW) annually. Specifically, by utilizing the power generated at six of the sites (approximately 0.5 MW) at the Tokyo Head Headquarters, the Fujisawa Plant and the Matsuida Plant, and the power from 21 of the sites (approximately 1.9 MW) at MITSUMI ELECTRIC's Tama Head Office and Atsugi Operation Base, the Group as a whole expects to reduce its CO2 emissions by approximately 1,755t-CO2 per year.
Looking ahead, as the MinebeaMitsumi Group continues to promote its green transformation (GX), it will work toward realizing its long-term environmental target of a 30% reduction of its CO2 emissions (based on a science-based target of 2 degrees Celsius) by the fiscal year ending March 2031 compared to the fiscal year ended March 2021.

Mitsubishi HC Capital provides financial support to Jikotaku Support through the leasing of power generation facilities, while Chuo Electric Power provides services such as imbalance control. Through their assistance to Jikotaku Support, both companies are contributing to the MinebeaMitsumi Group's GX


Through RenetS, Mitsubishi HC Capital and Chuo Electric Power began providing Jikotaku Support to Chuo Electric Power in November 2022, and its solar power plants are expected to be 100 sites (approximately 10 MW) by September 2023. Taking the provision of MinebeaMitsumi Group's services to the Kanto area as an opportunity, they aim to accelerate the provision of Jikotaku Support to the Group's other bases and to other companies, and to contribute to corporate carbon neutrality, as well as to increase the generation capacity to a scale exceeding 500 sites (50 MW) by December 2025.
