GE Vernova and THDC Commission India’s First Variable‑Speed Pumped Storage Generator

GE Vernova Inc. has commissioned the first of four 250 MW variable speed units at THDC India Limited’s Tehri Pumped Storage Hydropower Plant, part of the Tehri Hydropower Complex.

With this 1 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. GE Vernova has been chosen to provide a comprehensive "water-to-wire" solution for THDC India Limited, encompassing hydropower generation equipment, power electronics, and control systems. The scope of the project involves the integration of four variable-speed doubly fed induction motor-generators and their corresponding pump turbines with advanced power electronics and control technologies. This work is part of the Tehri Hydropower Complex, which includes the 1,000 MW Tehri Hydropower Plant (commissioned in 2006), the 400 MW Koteshwar Hydropower Plant (commissioned in 2012), and the 1,000 MW Tehri Pumped Storage Plant—where GE Vernova is currently deploying four 250 MW variable-speed pumped storage systems.
