On July 16, 2025, Osaka Prefecture and Hanwha Japan signed a partnership agreement under the SDGs partnership system "Green Alliance," marking the official launch of the installation of solar power generation systems in child welfare facilities and educational institutions within the prefecture. In this project, our company handles everything from design to construction in a unified system, achieving both rapid delivery and high quality. The facilities that adopt this system will consume approximately 120 MWh of renewable energy annually, significantly reducing electricity costs and enabling data provision for environmental education programs. [Background and Purpose of Implementation] Recently, the introduction of renewable energy in local governments is expected to play a role not only in reducing CO₂ emissions but also as an environmental education tool for the next generation. The "Green Alliance" promoted by Osaka Prefecture is a system that accelerates concrete efforts toward achieving the SDGs by fostering collaboration between businesses and government. In this partnership agreement, we aimed to combine the solar panels provided by Hanwha Japan with our construction know-how to implement the most suitable systems for child welfare and educational facilities in a short timeframe.
