Pumped hydro storage needs $20 billion investment in India: Study

Globally, PHS is an established, proven and cost-effective technology for storing electricity at times of high generation and or low demand which can then be released into peak demand periods

Pumped hydro storage (PHS) can play a key role in powering low-carbon electricity in India. Tapping into the PHS sector’s enormous potential needs at least $20 billion investments annually, says a research by the Institute for Energy Economics & Financial Analysis (IEEFA).

Plans are afoot for India to be the global leader in PHS. According to the IEEFA report, some 2.6 Gw of PHS is already operational in the country and another 3.2 Gw of projects is under construction. An additional 8.9 Gw is in the drawing board stage. Development of PHS, though, comes with
