Characteristics

First thermal power station outside our service area

This is Chubu Electric Power’s first thermal power station located on the Sea of Japan side of the country, outside our service area.

Power generation facility with high efficiency and low environmental burden

The power station will achieve thermal efficiency of at least 58%, the highest level in Japan, thanks to the multi-shaft combined-cycle power generation technology using 1,300°C class improved gas turbines.

This will allow us to use limited energy resources more effectively while reducing CO2 emissions.

In addition, the use of clean LNG as fuel eliminates soot.

High degree of automation

The facility is built to be controlled and monitored, from startup to shutdown, by a small number of workers in a central control room.
