Shizen Energy selected for the basic design work of microgrid construction in Kamishihoro, Hokkaido
Shizen Energy Inc. (Shizen Energy) and Pacific Consultants Co., Ltd. (Pacific Consultants) have been selected as the contractor for the basic design work for the construction of a microgrid in Kamishihoro, Kato-gun, Hokkaido through a public bidding proposal process.
The town of Kamishihoro declared its “Zero Carbon City Declaration” in December 2021, and plans to systematically implement integrated initiatives that contribute to renewable energy and energy conservation, aiming to “realize a zero carbon Kamishihoro and build a smart town,” including global warming countermeasures as one of the “decarbonization leading region” selected by the national government in April 2022.
One of the priority initiatives, the project to construct a micro-grid for public facilities using solar power generation, aims to strengthen resilience by effectively utilizing renewable energy through solar power generation and storage batteries during normal times and supplying electricity to major public facilities such as the town hall building, sports center, transportation terminal, Fureai Plaza, and certified child care centers in the event of a disaster.
This project aims to conduct research and study on the most appropriate business model, construction model, and commissioning model for the construction of a micro-grid for public facilities utilizing solar power generation, as well as to create a basic scheme and basic design.
Shizen Energy and Pacific Consultants will utilize their accumulated experience and track record in microgrid projects to provide support for the construction of a microgrid for public facilities in Kamishihoro through this project.
