Production Test at Takigami Power Station
Production Test at Takigami Power Station
Since the 1970s, Idemitsu has placed an emphasis on geothermal energy. Attracted to the promise of this renewable energy source, we commenced the operation of Takigami Power Station as a joint venture with Kyusyu Electric Power Company Inc in Kokonoe town, Oita at 1996.
Idemitsu has been supplying geothermal steam to Takigami power station to generate 25,000kW on constant basis and upgraded to 27,500kW equivalent since June 2010.
