VADODARA, India (June 6, 2025) – GE Vernova Inc. (NYSE: GEV) announced the successful commissioning of the first 250-megawatt (MW) variable speed pumped storage unit at THDC India Limited’s Tehri Pumped Storage Hydropower Plant. The facility is part of the larger Tehri Hydropower Complex in Uttarakhand, India.

The expansion project includes four variable speed pumped storage units, each rated at 250 MW. Once all units become operational, the Tehri complex is expected to reach a total generation capacity of 2.4 gigawatts (GW), making it the largest hydropower complex in India.

In addition to supplying electricity, the Tehri reservoir system is also expected to support irrigation and drinking water needs across the region, particularly during periods outside the monsoon season.

GE Vernova was selected by THDC India Limited to provide a complete “water-to-wire” solution for the project, including hydropower generation equipment, electrical systems, power electronics, and advanced control technologies.

“With this development, Tehri becomes the first hydropower facility in India to implement variable speed pumped storage technology,” said Frederic Ribieras, CEO of GE Vernova’s Hydro Power business. “The new units are designed to rapidly switch between pumping and generation modes, allowing faster load response and significantly greater flexibility for the electrical grid. These capabilities are increasingly important as India continues integrating more renewable energy sources.”

Hydropower continues to play a major role in India’s renewable energy strategy. By early 2024, the country had installed roughly 51 GW of hydropower capacity, placing India among the world’s leading hydroelectric producers.

Pumped storage facilities operate similarly to large-scale energy storage systems. During periods of excess electricity generation, water is pumped from a lower reservoir to an upper reservoir. When energy demand increases, the stored water is released back through turbines to generate electricity. Globally, pumped storage technology currently represents the vast majority of long-duration energy storage capacity.

For the Tehri project, GE Vernova is integrating four variable speed doubly fed induction motor generators along with associated pump turbines, converters, control systems, and electrical infrastructure. The system is designed to improve operational efficiency while helping stabilize the grid during fluctuations in renewable energy production.

The Tehri Hydropower Complex currently includes:

• The 1 GW Tehri Hydropower Plant, commissioned in 2006
• The 400 MW Koteshwar Hydropower Plant, commissioned in 2012
• The 1 GW Tehri Pumped Storage Hydropower Plant, currently under expansion with four 250 MW variable speed pumped storage units supplied by GE Vernova

GE Vernova maintains a significant operational footprint in India across electricity generation, transmission, and distribution sectors. The company operates five technology and engineering centers focused on research and innovation, along with 11 manufacturing facilities supporting domestic production and employment. Its workforce in India includes more than 10,000 employees, including over 3,000 engineers and technology specialists.
