Start of Operations on Joetsu Thermal Power Line

June 08, 2011
Chubu Electric Power Co.,Inc.

This is to announce that Chubu Electric Power today completed the preoperational voluntary inspection of the Joetsu Thermal Power Line as prescribed in the Electricity Business Act, Article 50-2, and started line operations.

The Joetsu Thermal Power Line is a 275-kV transmission line connecting the Joetsu Thermal Power Station (currently under construction in Joetsu City, Niigata Prefecture) and the Shin-Hokushin Substation (Nagano City, Nagano Prefecture). It has 124 towers over its 62.7-km length.

Presently, we depend on power sources like thermal power stations on the Pacific Ocean side of the country to supply electric power to Nagano, which requires transmitting power over long-distance lines. With the start of operations at the Joetsu Thermal Power Station (where equipment is scheduled to be started in succession beginning in July 2012), electric power will be supplied to Nagano from power sources on both the Pacific Ocean and Sea of Japan sides, further enhancing power system stability.

Chubu Electric Power will continue to respond accurately to future demand trends and power supply development and will rationally and systematically deploy equipment as we work to ensure a stable supply of electric power.
