New Delhi: State-run hydropower major NHPC Limited has announced that the annual revenue from its 520 MW Parbati–III Power Station is set to rise significantly by Rs 224.70 crore following the commissioning of the 800 MW Parbati-II Hydro Electric Project in Himachal Pradesh.
In a regulatory filing on Thursday, NHPC said that power generation at the Parbati-III station is projected to increase substantially from 572 million units (MUs) in 2024-25 to 1,669 MUs in 2025-26. As a result, the station’s revenue is expected to rise from Rs 200.50 crore in FY2024-25 to Rs 425.20 crore in FY2025-26.
The Parbati-III Power Station, commissioned in 2014, is located downstream of the Parbati-II project and will directly benefit from the latter’s operations. The newly commissioned Parbati-II, a 4x200 MW run-of-the-river project, has recently commenced commercial operations.
The Parbati-II project is designed to harness the hydroelectric potential of the lower reaches of the Parbati River. Water from the river is diverted at Village Pulga in the Parbati valley through a 31.52-kilometre-long Head Race Tunnel (HRT) to a powerhouse located at Village Suind in the Sainj valley. The project exploits a gross head of 863 metres between Pulga and Suind to generate 800 MW of electricity.
Parbati-III, a pondage type scheme, plays a crucial role in providing peaking support to the power grid. It utilizes water from multiple sources — the Parbati River, Manihar Nallah, Panch Nallah, Huria Nallah, and Jiwa Nallah — via the Parbati-II Hydro Electric Project and the Sainj River.
