Construction Plan for Seinaiji Hydroelectric Power Station

March 07, 2016
Chubu Electric Power Co.,Inc.

Chubu Electric Power would like to announce its decision to construct the Seinaiji Hydroelectric Power Station that harnesses the streams of Kuro and Koguro Rivers, both of which belonging to the Tenryu River system.

The Seinaiji Hydroelectric Power Station is a run-of-the-river power station with a generation capacity of 5,600 kW. Chubu Electric Power plans to start constructions in FY2018 and commence the power station's operation in FY2022.

This is the first new run-of-the-river hydroelectric station for Chubu Electric Power to develop in 20 years since the Hiraya Hydroelectric Power Station (output: 8,100 kW) that went into service in 1996.

Chubu Electric Power will develop the Station under the continued understanding and cooperation of local authorities and residents alike.

The Company is actively engaging in the development of renewable energy with sights set toward contributing to achieving improved energy self-sufficiency rates and reducing greenhouse gas. Hydropower generation in particular has the potential of providing stable electric power generation, and the company will accordingly maintain its efforts to develop both conventional and regular water-flow release hydroelectric power stations.

Chubu Electric Power will also systematically improve existing hydroelectric power station facilities in a drive to boost both the output and electric power generation of the stations.
