BACKGROUND

[002] Consumption of electricity has increased in each and every sector like industrial, domestic, agriculture etc. This has led to a greater demand for power generation. The different methods available to generate power are hydro, thermal, solar, wind, nuclear etc. But all of these methods are used to generate power at a large scale and also they require more expenditure in terms of installation and configuration of heavy machinery.

[003] Typically, the hydropower is considered to be a clean, renewable source of energy. The conventional hydropower plants working with single penstock only and these types of plants cannot send back the used water to the same headrace. The conventional hydropower generation plant is highly expensive and also time and cost required to construct the project's cost is high.
