Explanation: The Mettur hydro-power project, also known as the Mettur Dam, is a significant hydroelectric and irrigation project located in Tamil Nadu, India. It is situated on the Kaveri River, which is one of the major rivers in South India. The dam is located in the Salem district of Tamil Nadu and is a critical infrastructure for the state's power generation and irrigation needs.
The Mettur Dam was constructed between 1934 and 1936 and is one of the largest hydroelectric projects in Tamil Nadu. It serves multiple purposes, including power generation, irrigation, and flood control. The dam is a concrete gravity dam and has a length of about 1,550 meters and a height of 48 meters. The reservoir created by the dam, known as the Mettur Reservoir, has a capacity of about 1,100,000 acre-feet of water.
The project is managed by the Tamil Nadu Generation and Distribution Corporation (TANGEDCO) and is a vital part of the state's power infrastructure. The dam generates electricity through its hydroelectric power plant, which has a capacity of about 120 MW. The irrigation facilities provided by the dam benefit a large area of agricultural land in the region.
It is important to note that while there are several hydroelectric projects in South India, the Mettur Dam is specifically located in Tamil Nadu. Other states in the region, such as Andhra Pradesh, Kerala, and Karnataka, have their own significant hydroelectric projects, but the Mettur Dam is unique to Tamil Nadu.
In summary, the Mettur hydro-power project is a critical infrastructure in Tamil Nadu, serving both power generation and irrigation needs. Its location in Tamil Nadu is a key piece of geographical and infrastructural knowledge for students and professionals interested in the region's power projects and geography.
