Kodayar-I&II Hydroelectric Power Plant, Tamil Nadu, India

Kodayar-I&II is a hydroelectric power plant located in the state of Tamil Nadu, India, with a capacity of 100 megawatts. The facility is operational and plays a role in the region's power generation mix, leveraging the local water resources for clean energy production. As a hydroelectric plant, Kodayar-I&II operates without direct fuel combustion, resulting in minimal air emissions compared to thermal power plants. The facility's capacity of 100 MW places it in the medium-scale range for hydroelectric projects in India. The plant is subject to Indian environmental regulations, including the Environmental Impact Assessment (EIA) notification and the Water (Prevention and Control of Pollution) Act, which govern water use and ecological protection. The plant contributes to the local grid, supporting energy needs in Tamil Nadu. Hydroelectric power provides flexibility for peak load management and helps integrate variable renewable sources. The facility's operation aligns with India's goals for increasing renewable energy capacity and reducing carbon intensity in the power sector.

The Kodayar-I&II hydroelectric plant is situated in the Western Ghats region, an area known for its biodiversity and ecological sensitivity. The plant uses water from the Kodayar River, which supports local ecosystems and agriculture. Hydroelectric projects in this region must balance power generation with environmental flow requirements to maintain downstream habitats. The facility's carbon footprint is low compared to fossil fuel plants, but it may affect local hydrology and aquatic life.
