Participation in Abashiri Biomass Power Generation ProjectJapan Petroleum Exploration Co., Ltd. (JAPEX) participated in the biomass power generation project(hereinafter “the project”), consisting of the 2nd and 3rd of the Abashiri Biomass Power Plant, which is underdevelopment in the Notoro Industrial Complex at Abashiri city, Hokkaido.
The project was originally launched by WIND-SMILE Co., Ltd. (hereinafter “WINS”), which mainly
engaged in the development and design, sales, construction, and operation and management of natural energy
power generation systems. Currently, the project is under construction by the two special purpose companies(SPC) for the 2nd and 3rd plants (hereinafter “the two SPCs”), as the business owners which were established
by WINS. The 2nd plant is scheduled to start commercial operation in May 2022, and the 3rd plant in December
2022. The output scale for each plant is 9,900kW (total of 9,800kW), planning to use domestic wood chips from
Hokkaido.
Our participation in the project is due to the match of interest between WINS and us: WINS had been
seeking new sponsors of the project as the development progress of 2nd and 3rd plants, and JAPEX had been
aiming to participate in renewable power generation project that will enable us to acquire experience andknowledge in business operations and make a significant contribution to the local community. JAPEX
completed the participation procedure in the project by the investment to the two SPCs on September 30,
2021.
Please refer the appendix for the outline of the project such as power plants and the two SPCs.
JAPEX, with the two SPCs and sponsors, will contribute to expanding the use of electricity derived fromrenewable energy sources with low environmental impact and developing local economies, with theunderstanding and support from local stakeholders.
