As part of the environmental contribution project “Osaka Hikarinomori Project,” a mega-solar power generation plant was recently completed at the Hokko Landfill Site on Yumeshima in Osaka’s Konohana-ku, and the project has now been fully launched.
The “Osaka Hikarinomori Project” is a corporate participation-based environmental contribution project initiated to make effective use of the Hokko Landfill Site on Yumeshima in Konohana-ku, Osaka through public-private collaboration. Multiple companies will bring funding and know-how to the Project, utilizing leases to share the costs of installing the mega-solar facility, and they will receive earnings from the sale of the generated electricity to the local electric power company in proportion to their share of the costs.
The Hokko Landfill Site serving as the installation location for the mega-solar plant is a landfill disposal site for incinerated ash. Although the site is very spacious, it will continue to be used for landfill disposal, making ordinary land use at the site impossible. To solve this problem, in 2010, Osaka City invited from the general public appropriate ideas for using the site. Adopted was the Solar-power Group Share (SGS), a scheme proposed jointly by Sumitomo Corporation and Sumitomo Mitsui Finance & Leasing Co., Ltd. in order to enable numerous companies to participate in a mega solar power generation project. This has resulted in the Osaka Hikarinomori Project. The initial members at the time of the beginning of the Project were the seven companies of Sumitomo Electric Industries, Ltd., Jupiter Telecommunications Co., Ltd., Sumitomo Corporation, DAIHEN Corporation, Hitachi Zosen Corporation, Rengo Co., Ltd., and NTT Facilities, Inc.
Subsequently, the two companies of Sumitomo Warehouse Co., Ltd. and Osaka Shinkin Bank joined the project. Currently, the project is promoted by the nine companies.
The Project was founded on the concept of multiple companies coming together to create a “Hikari-no-Mori” (Forest of Light), similar to the way individuals would plant one tree each to create a forest. The part of the Hokko area where the landfill is completed will be effectively utilized as the large-scale mega solar project site, which will contribute to the environmental improvement of the area. As clean energy, the renewable electricity generated, which is eligible for the feed-in-tariff (FIT), will support the day-to-day lives and economic activities of the local community via Kansai Electric Power Co., Inc.
As the Project is situated at a waste disposal site, it is subject to many restrictions, so the participating companies have implemented a wide range of additional measures to ensure stable operation over the long term. Nevertheless, construction, maintenance and management costs are relatively higher, so the Project is being pursued through collaboration between the national and local governments and private companies in the form of interest subsidies for Comprehensive Special Zone projects from the Cabinet Office and local tax incentives from Osaka City.
Through the “Osaka Hikarinomori Project,” the participating companies strive to help conserve the global environment, promote renewable energy generation in urban areas, and contribute to environmental education that passes on the principles of sustainable communities to the next generation.
