Chubu Electric Power Co.,Inc.

The special purpose company "M&C Tottori Hydro Power Co., Ltd." (the "SPC"), established by Chubu Electric Power Co., Inc. ("Chubu Electric Power") in partnership with Mibugawa Electric Power Co., Inc., Chubu Co. Ltd. and Miho Technos Co., Ltd. (the "Three Partners"), has commenced the operation of the Tsukuyone Hydro Power Station, owned by Tottori Prefecture, on September 01, 2020.

In March 2019, Tottori Prefecture sought expressions of interest for a redevelopment and administration project (the "Project") for redeveloping four of the Prefecture's hydropower stations that has reached or passed half a century in operation, and transferring the operation rights of the plants to a special purpose company for a period of 20 years. Chubu Electric Power formed a consortium with the Three Partners to apply for the Project and successfully won a right of first negotiation in March 2020.

The SPC was subsequently formed in May 2020, and signed a specified business agreement with Tottori Prefecture in July 2020. This is Japan's first PFI project (Note 2) for hydro power facilities to be undertaken in the concession method (Note 1).

On September 01, 2020, the SPC takes over the operation of the Tsukuyone Hydro Power Station, one of the four hydro power stations already redeveloped and currently operated by Tottori Prefecture. The remaining three power stations will undergo redevelopment, starting in FY2021, and will go operational as their redevelopment work completes.

Chubu Electric Power has 197 hydro power stations and 38 dams across the Chubu region (as of the end of July 2020), having ensured safe operations for many years and successfully handling redevelopment and other works on numerous hydro power stations. Chubu Electric Power will tap into insights from these achievements to contribute to safe redevelopment and operation of hydro power plants by the SPC.

(Note 2) A public works project approach that uses private-sector's fund, management ability and technological capability (know-how) to design, construct, repair, update, maintain, manage and operate public facilities
