Shimla: Himachal Pradesh chief minister
Sukhvinder Singh Sukhu said on Tuesday that the state government has decided to venture into the technologically advanced domain of pumped storage projects (PSPs) as these projects were considered one of the most reliable in balancing power supply from renewable sources such as solar and wind energy.
The council of ministers, in its recent meeting, had approved the allotment of first two such projects - 1630 megawatt (MW) Renukaji Pump Storage Project in Sirmaur district and 270 MW Thana Plaun Pump Storage Project in the Beas Basin of Mandi district — to the Himachal Pradesh Power Corporation Limited (HPPCL).
In the PSP system, water is pumped from a lower to a higher elevation reservoir using low-cost electricity, typically during off-peak hours. When electricity demand rises, the stored water is released back through turbines, converting potential energy into electricity, ensuring energy supply. Work on both projects is already underway, with two distinct powerhouses, one for regular power generation and another dedicated to the PSP system.
“Himachal Pradesh, being a hilly state, is ideally suited for pumped storage projects. The geography offers immense potential for constructing such projects, which will ensure grid stability as these projects are crucial for mitigating power shortages during high-demand periods by releasing stored water to generate electricity through turbines,” added the CM.
He said under the Swaran Jayanti Policy, 2021, the state prioritises the development of PSPs. Proposals for both identified and self-identified PSPs, along with pre-feasibility reports, will be invited every six months. Sukhu added that the Satluj Jal Vidyut Nigam Limited (SJVNL) has identified four pumped storage projects with a total capacity of 2,570 MW, Bhakra Beas Management Board (BBMB) has identified eight projects with a combined capacity of 13,103 MW, and National Thermal Power Corporation Limited has identified two projects totalling 2,400 MW.
