GE Vernova Inc. (NYSE: GEV) announced today that it has commissioned the first of four 250 megawatts (MW) variable speed units at THDC India Limited’s Tehri Pumped Storage Hydropower Plant, part of the Tehri Hydropower Complex. With this 1 gigawatt (GW) expansion, the complex will reach 2.4 GW of generating capacity and become India’s largest hydropower complex. The project’s reservoir will also help provide support with irrigation and drinking water during non-monsoon periods to the state of Uttarakhand, where it is located.
“With this project, Tehri will become India’s first power plant to use variable speed pumped storage technology and the country’s most modern hydropower station. With fast transition between the turbine and pump operation, the four new units are expected to enable power control, leading to significantly improved grid flexibility. These are all crucial capabilities as more renewables are integrated into the country’s energy mix,” said Frederic Ribieras, CEO of GE Vernova’s hydropower business.
Hydropower remains a cornerstone of India's renewable energy landscape, with an installed capacity of approximately 51 GW as of early 2024, positioning the nation as fifth globally in hydroelectric capacity.

This technology is the largest source of long duration energy storage globally, representing about 94%* of total energy storage capacity.
For this project, GE Vernova capitalizes on its broad portfolio of technologies to generate, transfer and store power to deliver a full water to wire solution, spanning from electrical, hydraulic machines to converters. The project includes the integration of the four doubly fed induction motor generators and the associated pump turbines with the power electronics and control systems.
Tehri Hydropower Complex includes:
GE Vernova has a substantial presence in India, across generation, transmission and distribution. The company has five Technology and Engineering Centers focused on advancing research, development and innovation in new technologies and solutions. Additionally, the company operates 11 manufacturing sites that are undertaking local production and generating employment. The company’s workforce in India comprises of over 10,000 employees, including more than 3,000 engineers and technologists.
