Mitsubishi Heavy Industries and Chugoku Electric , based in Hiroshima, today concluded a basic agreement under which all electricity consumed at MHI’s Mihara Machinery Works will be replaced with green power, etc. derived from renewable energy sources by the end of fiscal 2023 (March 31, 2024). Under the agreement, Chugoku Electric will newly install 10-megawatt (MW) class photovoltaic (PV) facilities at the Mihara Machinery Works’ Wadaoki Plant, and will supply green power, etc. to MHI under a combination of onsite and offsite power purchase agreements.
The environmental value created by the PV facilities at the Wadaoki Plant will be applied to achieve full decarbonization throughout the Mihara Machinery Works, including its Itozaki and Kohama plants. Under the project scheme, the power generated by the PV facilities at the Wadaoki Plant will initially be used in-house at the plant, through the PPA onsite as specified. Any excess power will be supplied through the power grid to the Itozaki and Kohama plants, under an offsite PPA. When completed, the scheme – which is the first of its kind undertaken by either of the two project partners – will result in a near 10,000-ton annual reduction in the Mihara Machinery Works’ carbon emissions.
