Austria-based international technology group ANDRITZ has secured an order to equip Gujarat-based Torrent Power’s 3,000 MW Saidongar-1 pumped storage project (PSP) in Karjat, Maharashtra, with pump-turbines, motor-generators, and other electromechanical equipment.

The storage project will produce 6,241 GWh of energy annually.

ANDRITZ did not disclose the contract value but said it was in the low-three-digit-million-euro range.

The company must design, manufacture, install, test, and commission ten reversible pump turbines, motor-generators, and related electromechanical equipment. The project will be executed using ANDRITZ’s manufacturing facilities in India.

ANDRITZ is currently involved in seven PSPs in India with a combined installed capacity exceeding 11 GW.

This March, ANDRITZ secured an order from Tata Power to supply key equipment for the 1,000-MW Bhivpuri PSP in Maharashtra.

Last September, ANDRITZ received an order from Adani Green Energy for the 1,800 MW Gandikota PSP in the YSR Kadapa district of Andhra Pradesh.

It also secured an order from Adani Green Energy to supply pump turbines, motor generators, and other electromechanical equipment for the 1,500 MW Tarali PSP in Satara, Maharashtra.

Last April, the Central Electricity Authority (CEA) approved the detailed project reports for six PSPs, including the Bhivpuri project, with a total capacity of 7.5 GW.

India’s total installed PSP capacity is expected to reach approximately 87 GW by 2033-34, according to the CEA’s Roadmap to 100 GW of Hydro Pumped Storage Projects by 2035-36. The report said India’s resource adequacy studies highlight increasing requirements for long-duration energy storage. It stated that while battery energy storage systems are effective for short-duration applications, pumped storage is critical for meeting evening peaks and extended periods of high demand.

India’s growing need for energy storage has been outlined in the National Electricity Plan 2023, which projects a requirement of around 74 GW and 411 GWh of storage capacity by 2031-32. Of this, approximately 27 GW and 175 GWh are expected to come from PSPs.

In response to this growing demand, the Ministry of Power issued tariff-based competitive bidding guidelines earlier this year to facilitate the procurement of stored energy from PSPs, including those that are existing, under construction, or in the planning phase.
