Bhawani Kattalai Barrage Hydroelectric Power Plant, Tamil Nadu, India

Bhawani Kattalai Barrage is a hydroelectric power plant situated in Tamil Nadu, India, with an installed capacity of 30 megawatts (MW). This facility is part of India's growing portfolio of renewable energy projects, contributing to the country's goal of increasing non-fossil fuel power generation. The barrage utilizes the flow of the Bhavani River to generate electricity, supporting regional grid stability and reducing dependence on thermal power. The plant operates under India's regulatory framework for hydropower, which includes environmental clearance requirements and water use agreements. As a run-of-river project, it has a lower environmental footprint compared to large storage dams, though it still requires careful management of downstream flows. The technology involves turbines driven by the natural river current, with minimal water storage. Bhawani Kattalai Barrage plays a key role in the local energy mix, providing renewable power to the Tamil Nadu grid. Its operation supports the state's renewable energy targets and helps offset carbon emissions from fossil fuel plants. The facility also contributes to water management in the region, aiding irrigation and flood control.

The plant is located on the Bhavani River, a tributary of the Kaveri, in a region with significant agricultural activity. Hydroelectric generation here avoids the air emissions associated with thermal plants, but the barrage can alter local hydrology and aquatic habitats. The facility's run-of-river design minimizes reservoir-related impacts, though it still requires careful flow management to support downstream ecosystems and water users.
