Address: IN

Overview

The Teesta Low Dam - III Hydropower Plant is an operational hydroelectric power station situated on the Teesta River in the state of West Bengal, India. Classified as a run-of-the-river facility, the plant harnesses the natural flow of the river to generate electricity, contributing to the regional energy infrastructure. The station has an installed capacity of 132 MW and is operated by NHPC Limited. It was commissioned in 2013, marking a significant addition to the hydroelectric portfolio in the eastern part of the country.

Location and Geography

The plant is located at Rambi Bazar, within the Kalimpong district of West Bengal. This positioning places the facility in a geographically strategic area along the Teesta River, which flows through the Himalayan foothills before entering the plains. The specific location at Rambi Bazar allows for efficient water intake and discharge, characteristic of run-of-the-river hydroelectric systems that rely on the continuous flow of the river rather than large reservoir storage.

Operational Characteristics

As a run-of-the-river station, the Teesta Low Dam - III Hydropower Plant operates by diverting a portion of the river's flow through turbines to generate power before returning the water to the main channel. This method minimizes the surface area of water exposed to evaporation compared to reservoir-based plants, making it suitable for the climatic conditions of the region. The 132 MW capacity indicates a mid-sized installation capable of providing a steady output of electricity to the grid. NHPC Limited, the operator, manages the day-to-day operations and maintenance of the facility, ensuring consistent power generation since its commissioning in 2013.
