Thermal power is the "largest" source of power in India. There are different types of thermal power plants based on the fuel that are used to generate the steam such as coal, gas, and diesel, natural gas. About 71% of electricity consumed in India is generated by thermal power plants.
More than 62% of India's electricity demand is met through the country's vast coal reserves. Public sector undertaking National Thermal Power Corporation (NTPC) and several other state level power generating companies are engaged in operating coal-based thermal power plants. Apart from NTPC and other state level operators, some private companies also operate the power plants. One coal plant was given environmental clearance in 2021. Although new plants are unlikely to be built, if more coal is burnt in existing plants it will increase greenhouse gas emissions by India. Here is some list of operating coal-based thermal power plants in India.
The total installed capacity of major grid connected diesel-based power plants in India, is 509.71 MW. The installed capacity of captive power DG sets is estimated to be nearly 90,000 MW. Here is the part list of grid connected plants.
Site Selection for Hydroelectric Power Plant: In order to make the hydroelectric power plant economical, we have to consider some key points in the selection of a site for a hydroelectric power plant.
The key characteristics for the selection of the site for the hydroelectric power plant are that the site should accommodate a large catchment area, steep gradients for a good potential head, high average annual rainfall throughout the year, a suitable location for the building of storage or reservoir dams.
A hydroelectric power plant utilizes the potential energy of the flowing water to convert it into mechanical energy and thereby converting the mechanical energy into electrical energy with help of a generator. Water is the main fuel for such plants. Hence, selecting hydroelectric power plants near the site with adequate water supply, the good head seems to be important and necessary.
As mentioned earlier, a hydroelectric power plant primarily utilizes the potential energy of the flowing water. The available water head is directly proportional to the potential energy. So, the more the head, more will be the potential energy available and the more will be the generation of electricity. The availability of water heads also has a considerable significance on the cost and economy of the plant. With a high water head, a given hydroelectric power plant can be constructed with higher generation capability and lower cost.
The load center is the location or the place where the electricity produced by the plants will be consumed. Hydroelectric power plants are generally constructed in places far away from the load centers. So, a high amount of cost is required to erect the transmission lines in order to transmit the power from these generating stations to the load centers. The route of these transmission lines must be selected in advance and wisely to reduce the transmission cost.
For transportation of the goods, manpower required for the construction and operation of the hydroelectric plant, the site should be accessible by road. The accessibility of the site will make the transportation of machinery and required equipment easy.
The polluted water resource consists of various foreign particles. The foreign particles in the water will corrode the hydroelectric power plant structure such as the blades of the turbine. So, the site selection of the hydroelectric power plant must be done where there is the availability of good quality water.
For a continuous supply of water during dry seasons, dams and reservoirs are constructed in hydroelectric power plants. The catchment area of the reservoir should be large enough so that the water level in the reservoir will not fall below the minimum level during the dry season.
A large area of land is required for the construction of the hydroelectric power plants and build its constituent structures such as a powerhouse etc. For economic consideration, the land should be available at a cheap cost and should have a proper geological condition in order to withstand the weight of the structures and machinery of the power plants. 350c69d7ab
