Business overview
Power generation capacity
Approximately 10,000 kW (equivalent to 3,200 households)
Project period
October 2013 to the end of September 2033
This project adopts a new business model, the first of its kind in Japan (as of 2013), where multiple participating companies share the installation costs of the mega-solar system and receive a share of the revenue from selling the generated electricity to power companies according to their cost-sharing ratio.
Origin
The project aims to utilize the upper space of Yumeshima island（waste landfill site）, where incineration ash from general waste generated by Osaka City and surrounding municipalities is disposed of, for a large-scale solar power generation project.
This project not only aims to reduce CO2 emissions but also contributes to environmental education and regional contributions through public-private collaboration.

Features
This project differs from mega-solar projects that solely aim for profit and has the following features:
- Effective use of urban waste disposal sites
- Environmental contributions through public-private collaboration
- Environmental contributions through collaboration among multiple companies
- Contributions to environmental education and the community
The installed mega-solar system is used as educational material for environmental education, and part of the revenue from selling
electricity is utilized for Osaka City's environmental creation projects.
