Overview
Nagarjuna Sagar is a 815.6 MW hydroelectric power plant in India, operational and located on the Krishna River. It is one of the major hydropower facilities in the region.
Nagarjuna Sagar is a hydroelectric power plant located in India, with an installed capacity of 815.6 MW. The facility is operational and plays a significant role in the country's renewable energy portfolio. As a large-scale hydropower project, it contributes to grid stability and peak load management. The plant operates under India's regulatory framework for hydropower, which includes environmental clearance from the Ministry of Environment, Forest and Climate Change and compliance with the Dam Safety Act. The technology used is typical for run-of-river or reservoir-based hydroelectric plants, with turbines driven by water flow from the Nagarjuna Sagar Dam. Environmentally, the plant provides low-carbon electricity, reducing reliance on fossil fuels. However, large reservoirs can affect local ecosystems and water flow patterns. The facility supports agricultural irrigation and drinking water supply in the region, highlighting its multi-purpose benefits.
Environmental context
The Nagarjuna Sagar hydroelectric plant is situated in a semi-arid region where water resources are critical. The reservoir creation has altered local hydrology and may affect downstream aquatic habitats. However, the plant's zero-emission operation contributes to India's climate goals by displacing coal-fired generation. The facility's location near populated areas requires careful management of water releases to prevent flooding and ensure safety.
