The year 1957 saw the start of operation of the thermal power plant. While power continued to be produced for a long time obsolescence and aging of the equipment took their toll and at the same time electricity demand increased. To meet these challenges, the old plant was superseded by high-thermal efficiency, superior mobility, environmentally friendly Advanced Combined Cycle (ACC) generation type thermal power plant with a total output of 2,280 MW in June 2000. art of the power plant’s ground has been used to create the “Biotope Soga” nature-revival type park in which visitors freely walk about.
