Agency for Natural Resources and EnergyDesignation of Important Transmission Facilities as a Measure for Enhancing Nationwide System Operation Based on the Policy on Electricity System Reform

On August 22, 2014, the Ministry of Economy, Trade and Industry (METI) designated the following facilities of Tokyo Electric Power Company Incorporated (TEPCO) and Chubu Electric Power Co., Inc. (Chubu Electric Power) as important transmission facilities: Direct Current Trunk Line between Tokyo and Chubu Areas; Branch Line for the Frequency Converter Station between Tokyo and Chubu Areas; AC/DC Converter at the Shin Shinano Substation; and Interconnection and Conversion Substation between Tokyo and Chubu Areas (the facilities’ names are all tentative).

These transmission facilities are essential sites to increase the amount of power interchange between Eastern and Western areas of Japan, in which frequencies are different, by 900,000 kW. This is METI’s first designation under the system for designating important transmission facilities.

1. Outline of the System for Designating Important Transmission Facilities

The system is formulated based on the Policy on Electricity System Reform (Cabinet Decision on April 2, 2013). Under the system, based on a request of businesses operators, the METI Minister will designate important transmission facilities to facilitate administrative procedures under the related laws and regulations, in consideration of the current situation in which the development of interconnection lines between the areas of utility companies often requires long timeframes. Designating important transmission facilities will facilitate the development of important transmission facilities.

Note: METI designates such facilities after asking for the opinions of prefectural governors and holding meetings with related ministries and agencies (Ministry of Land, Infrastructure, Transport and Tourism, Ministry of Agriculture, Forestry and Fisheries, Forestry Agency, Agency for Cultural Affairs and Ministry of the Environment).

In addition, specific sites in which important transmission facilities are developed will be determined after stipulating administrative procedures under the related laws and regulations and reaching a consensus with local residents.
