Power equipment manufacturer Bharat Heavy Electricals (Bhel) has commissioned the fourth unit of 800MW Koldam Hydro Electric Project in Himachal Pradesh, India.
Previously, three hydro power generating units, each having a capacity to produce 200MW, had also been commissioned by the Indian firm.
The project is the first hydro project owned by Indian energy conglomerate National Thermal Power Corporation (NTPC).
The surface power plant is situated at the embankment on River Sutlej in Mandi district. It had all the four units installed within 75 days.
Four Francis Turbines feature at the facility. These were manufactured by Bhel and operate at a height of 131.2m.
Bhel was responsible for the supply and installation of the turbines at the plant, along with associated synchronous generators, static excitation system, main inlet valves, digital governors and control and monitoring system (SCADA), as well as associated station auxiliaries and electrical and mechanical balance of plant (BoP) equipment.
Now fully operational, the hydro power generating facility will be able to supply 3,054GWH of renewable energy per year.
The plant was designed under a run-of-the-river scheme. It will be able to bring down greenhouse gas emissions in the state.
Other NTPC-owned hydro projects are also being carried out by Bhel. These include Tapovan Vishnugad HEP (4x130MW), Lata Tapovan HEP (3x57MW) and Rammam Stage-III HEP (3x40MW).
