THDC India Limited has officially commenced commercial operations for the first 250 MW unit of the Tehri Pumped Storage Plant (PSP), marking a significant milestone in India’s renewable energy journey. This development enhances grid stability and supports the integration of renewable energy...

Key Highlights

The Tehri PSP is India’s first variablespeed pumped storage plant, designed to provide flexible peaking power and critical grid balancing support.
The first unit, with a capacity of 250 MW, is part of the larger 1,000 MW Tehri PSP project.
The plant’s variablespeed technology allows precise control over power flow, improving efficiency and grid stability.
The commercial operation declaration (COD) was virtually addressed by Union Minister of Power, Housing and Urban Affairs Manohar Lal, alongside senior officials from the Ministry of Power and THDC India Limited.
The project is expected to elevate the Tehri Hydro Power Complex’s total capacity to 2,400 MW, making it India’s largest hydropower complex.
GE Vernova supplied the power electronics and controls for the 250 MW variablespeed unit, ensuring advanced technological integration.

Technological Advancements

The Tehri PSP introduces variablespeed technology, a first for India’s hydropower sector. This innovation enables realtime adjustments in power generation, allowing the plant to efficiently manage fluctuations in renewable energy supply. The system’s ability to convert offpeak surplus energy into peaking power enhances grid resilience and ensures roundtheclock power availability.

Impact on India’s Energy Sector

The successful operation of the Tehri PSP’s first unit is a major step toward India’s energy selfreliance. By providing flexible energy storage and balancing capabilities, the plant plays a crucial role in integrating renewable energy sources such as solar and wind into the national grid. The project sets a precedent for future pumped storage developments, reinforcing India’s commitment to clean energy solutions.

Future Prospects

THDC India Limited plans to fully operationalize the remaining units of the Tehri PSP, further strengthening India’s hydropower infrastructure. The project’s completion will significantly contribute to the country’s renewable energy targets, ensuring a more reliable and sustainable power ecosystem.
