Osaka Gas Co., Ltd. (hereinafter “Osaka Gas”) and GPSS Holdings, Inc. (hereinafter “GPSS”) have agreed to jointly develop the second phase*¹ of their medium- and small-sized non-FIT/non-FIP solar power plants (hereinafter “the Power Plant”). Today, both companies each made a 50% investment in GDsPJ2 LLC, the operating company responsible for managing the Power Plant.

In recent years, the expansion of renewable-energy introduction has led to a decline in available land suitable for the development of large-sized solar power plants. In response, Osaka Gas and GPSS signed a memorandum of understanding in 2021*² to collaborate on the continuous development of medium- and small-sized solar power plants and have since worked together toward that goal.

Under this new initiative, the two companies will utilize the “Subsidy for Promoting Solar Power Installation Led by Consumers”*³ from Japan’s Ministry of Economy, Trade and Industry (FY2024 initial budget). Through a joint investment (50% each) in GDsPJ2 LLC, we will develop five solar power plants in Japan with a combined capacity of approximately 7,000 kW. Construction of the Power Plant is scheduled to begin sequentially from April 2025, with operations to commence by February 2026.

With the development of the Power Plant, the total number of solar power plants jointly developed by Osaka Gas and GPSS will reach 17 sites, with a combined capacity of approximately 23,000 kW.

The Daigas Group aims to contribute to the achievement of carbon neutrality by 2050 by increasing the use of renewable energy worth 5 GW* in Japan and overseas, including in-house development and ownership as well as procurement from other companies, by FY2030.　Including the Power Plant, the Group’s renewable energy contribution will reach approximately 3,570,000 kW.

The GPSS Group is promoting power generation projects using sustainable energy sources such as solar, geothermal, hydro, wind, and waste through joint ventures with local communities that possess these resources, aiming to realize a sustainable society.

Both Osaka Gas and GPSS remain committed to advancing the adoption of renewable energy and the realization of a sustainable society.
