New Delhi: India's total installed capacity of pumped storage projects (PSPs) is expected to cross 100 GW by 2035-36 with the average annual capacity addition projected to be 9 GW, according to the Central Electricity Authority (CEA).
The investment required for upcoming PSPs is estimated at around Rs 5.8 lakh crore, calculated at an average cost of Rs 6 crore per MW, CEA said in a report outlining the roadmap for PSPs till 2035-36 on Wednesday.
PSPs in India involve significant capital investment because these projects require major civil works, electro-mechanical equipment, and supporting infrastructure, the power sector planning body said.
Based on its projections, the PSP installation has been planned up to 2035-36 to meet the growing need for long-duration energy storage.
The investment requirement is spread over multiple years for each project, typically with 20% expenditure in the first year, 30% in the second year, 30% in the third and the remaining 20% in the fourth year.
The phased expenditure pattern will help manage cash flow and ensure timely procurement, it said.
However, with increasing potential, especially under 'off stream close loop PSP' with a gestation period of around 4 years, the commissioning may accelerate during later years, the report said
India aims to add 500 GW non-fossil fuel based installed capacity by 2030, 701 GW by 2035 and 2,187 GW by 2047 based on generation planning studies.
Resource adequacy studies have been carried out by CEA for all states till 2034-35 and it found that long term storage would be required for integrating more green energy beyond 2030.
As per the CEA, PSPs provide a comprehensive solution for meeting future storage capacity requirements at reasonable cost besides ensuring grid reliability by providing frequency regulation and voltage support.
