GE to set up Pumped Hydropower Storage in India

Tags: International News

The American Multinational Company, General Electric (GE) has entered into agreements with THDC India, National Hydro Power Corporation (NHPC) and Megha Power to set up a combined pumped hydropower storage capacity of 1.5 Giga Watt (GW) for them.

  • Under pumped hydro storage, a large volume of water is released from a reservoir at a height of up to 500 metres  that rotates a turbine and generates power of up to 1 GW in the process.

  • The water released is collected in another reservoir below and after an operation of 10-12 hours is pumped back to the upper reservoir. So there is no displacement of the resource and it’s ploughed back.

  • The cost to set up one megawatt of such capacity is Rs 1-1.2 crore, which means that the total project will cost Rs 1,500-1,800 crore. This compares with Rs 4 crore per MW of thermal power and Rs 2.5 to 3 crore of renewable energy.

  • Pumped hydro is seen as an alternate, most economical and reliable form of peak power generation that can easily provide 400 MW to 1GW in less than 60 seconds at a cost less than half of conventional power generation.
