The Shiga Bank, Ltd. (President: Shinya Kubota, hereinafter 'Shiga Bank'), Shigagin Energy Co., Ltd. (Representative Director: Daisuke Umehara, hereinafter 'Shigagin Energy'), Osaka Gas Co., Ltd. (Representative Director and President, CEO: Masataka Fujiwara, hereinafter 'Osaka Gas'), and Daigas Energy Co., Ltd. (Representative Director and President: Hiroyoshi Fukutani, hereinafter 'Daigas Energy') have agreed to build a 'self-production and self-consumption*1' model (hereinafter 'this initiative') to supply renewable energy (hereinafter 'renewable energy') electricity, utilizing the environmental value derived from solar power plants owned by Shigagin Energy, to Shiga Bank's head office and other locations. Starting today, Osaka Gas has begun supplying renewable energy electricity to Shiga Bank, and in the future, it will supply this electricity by combining it with the environmental value derived from the solar power plants owned by Shigagin Energy.
This initiative uses Osaka Gas's 'FIT specific wholesale supply*2' mechanism to supply the environmental value derived from the solar power plants owned by Shigagin Energy, combined with renewable energy electricity, to Shiga Bank's head office building and major branches with large contracted electricity capacities. Furthermore, the renewable energy electricity supplied will be sold by Daigas Energy, an agent of Osaka Gas, under the renewable energy electricity pricing menu 'D-Green'.
This initiative, in which the environmental value created by the Shiga Bank Group is utilized within the group, simultaneously achieves a regional circulation of energy and a reduction in environmental impact through the use of renewable energy.
Going forward, the four companies will expand this 'self-production and self-consumption' initiative into a 'local production for local consumption' initiative, where regionally derived renewable energy is utilized within the region, thereby promoting the decarbonization of the entire region and working toward the realization of a carbon-neutral society.
## Initiatives of the Shiga Bank Group
In its 8th Medium-Term Management Plan formulated in April 2024, Shiga Bank set a goal of achieving net zero greenhouse gas emissions in Scope 1 and 2 by March 2029.
The annual power generation of the solar power plants owned by Shigagin Energy, established in the same year, reaches about three times the annual electricity consumption of the Shiga Bank Group. Through the construction of an energy 'self-production and self-consumption' model, the group will accelerate its efforts toward the realization of a decarbonized society in the region.
The Shiga Bank Group will continue to contribute to the realization of a sustainable society together with the region, under the purpose of 'Making the region happy with "Sanpo-Yoshi" (three-way satisfaction)'.
## Initiatives of the Daigas Group
Toward the realization of carbon neutrality by 2050, the Daigas Group aims to expand its contribution to the spread of renewable energy to 5 million kW*3 by FY2030, both domestically and internationally, including procurement from other companies in addition to its own development and ownership.
Going forward, as a retail electricity provider, the group will continue to actively support 'local production for local consumption' initiatives that utilize regionally derived renewable energy within the region, and work together with corporate customers promoting decarbonization to solve issues toward the realization of a carbon-neutral society.
*1: Utilizing the energy one has created oneself. A coined word capturing local production for local consumption from the perspective of the main actor.
*2: A mechanism that allows electricity generated by FIT power sources (power plants certified under the feed-in tariff system for renewable energy) to be wholesale-supplied to a retail electricity provider by 'specifying a specific power plant,' without going through the wholesale electricity market.
*3: Includes projects under construction or already decided upon, as well as power sources applicable to the FIT system.
