About Organisation

Guru Gobind Singh Super Thermal PowerPlant is situated near village Ghanauli on Chandigarh-Manali highway. It is about 12 km from Roopnagar and 55 km from Chandigarh.The power plant is one of the coal based power plants of PSPCL.The plant has an installed capacity of 1260 MW i.e. six units of 210 MW each.The first unit was commissioned in September, 1984. During March 1985, the second unit was commissioned and in later years four more units were added.

The plant has its source of water supply from Nangal Hydel Channel. The coal used mainly comes from mines in Bihar, West Bengal, Jharkhand, Chhattisgarh and Madhya Pradesh from more than 50 sources called collieries.It has 210 MW, 3 cylinder mixed flow tandem coupled, 3000 rpm BHEL make turbines.It has 247 MVA, 15.75 kV, 9050 A at 0.85 lag, 50 Hz, 3 phase, double star two pole generators.
