Chugoku Electric Power will develop its first grid-scale battery storage facility, a 10MW/30MWh project in Kudamatsu City, Yamaguchi Prefecture, the company announced at the end of last year.
According to the statement, the facility will sit on the site of the former Kudamatsu Power Station, a 700MW oil-fired power plant inactive since February 2019 and decommissioned at the end of January 2023. Chugoku EPCO aims to commission the power storage station during FY2028.
Chugoku EPCO’s project is one of the 27 selected as the recipients of METI’s FY2024 subsidy for the construction of grid-scale storage and one of the two such projects in the Chugoku TSO area. The subsidy will cover approximately 2 billion yen of the project costs.
The other project is being developed by Mizuho Lease’s ML Power in Hiroshima Prefecture and was awarded a smaller, approximately 1.2 billion yen subsidy.
