In a typical 210 MW power plant, six bowl mills are installed. As per the design condition of coal, four mills have to work continuously, one mill will be hot standby, and the other mill will be cold standby. But due to the use of inferior coal quality in most of the power plants, five mills are working continuously and the sixth mill is a standby.

In general, the greater the water flow and the higher the head, the more electricity a hydropower plant can produce. At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine that spin to power a generator to produce electricity. Conventional hydroelectric facilities include:

The basic idea is that wind turbines use blades to collect wind's potential and kinetic energy. Wind turns the blades, which spins a rotor that is connected to a generator to create electric energy. Most wind turbines have four basic parts: Blades are attached to a hub, which spins as the blades turn. The blades and hub together make the rotor.
