The dam's 1,000 MW variable-speed pumped-storage scheme is currently under construction, with the commissioning of the first two units was expected to be completed in 2023, which got finished in March 2024, and the rest to be done by 2025.

However, in 1988 the Tehri Hydro Development Corporation was formed to manage the dam and 75% of the funding would be provided by the federal government, 25% by the state.

[4] Tehri pumped storage plant (4 X 250 MW) has variable speed features which can optimize the round trip efficiency under varying water levels in its reservoirs.

Virendra Dutt Saklani, lawyer and founder of the Anti-Tehri Dam Struggle Committee, was quick to point out the consequences associated to the large project.

Were such a catastrophe to occur, the potentially resulting dam-break would submerge numerous towns downstream, whose populations total near half a million.

The relocation of more than 100,000 people from the area has led to protracted legal battles over resettlement rights and, ultimately, resulted in the project's delayed completion.

This reduction has been central to local protest against the dam, since the Bhagirathi is considered part of the sacred Ganges whose waters are crucial to Hindu beliefs.

On 21 November 2019, the Government of India approved the take over of Tehri Hydro Development Corporation (THDC) by NTPC Limited.
