The HVDC back-to-back facility Shi Shinano uses thyristor static inverters and went into service in 1977. The Shin-Shinano operates with a dc link voltage of 125 kV. The station was initially rated 300 megawatts. In 1992 the maximum transferable power was uprated to 600 megawatts.
The Shin Shinano Frequency Converter Station is one of three frequency converter stations that link Japan's western and eastern power grids. The station houses two converters, one of which opened in 1977, the other in 1992. The other two stations are at Higashi-Shimizu and Sakuma Dam.
