Hydro Power Project

HydroThe Mangalpur Hydro Electric Project located in Kalahandi District of Orissa, envisages utilization of the waters of the Hati river and down stream of Indravati river (a tributary of Tel River) harnessing a hear of 10 m in the immediate stretch of the river just below the Mangalpur barrage in addition to harnessing a head of 7.2 m from the run of the canal system of Hati barrage. i.e., Left main canal. The Project lies in Mangalpur village just downstream of the barrage lying on the left bank of Hati river.

The proposed installation of 7.5 MW (2x 1.25 MW: river Block and 2 x1.25MV canal block) will generate annually during a 90% dependable year a quantity of energy estimated to be 21.88 MU.

The proposed project site is located at 19 0 25’47”25.10 E. The project site being just below the barrage is already well connected with existing motor able road to Mukhiguda, Mangalpur village, UIHEP project sites and the Indravati power house.

Generating methods

Conventional (dams)

HydroMost hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water’s outflow. This height difference is called the head. The amount of potential energy in water is proportional to the head. A large pipe (the “penstock”) delivers water to the turbine.

Pumped-storage

This method produces electricity to supply high peak demands by moving water between reservoirs at different elevations. At times of low electrical demand, excess generation capacity is used to pump water into the higher reservoir. When there is higher demand, water is released back into the lower reservoir through a turbine. Pumped-storage schemes currently provide the most commercially important means of large-scale grid energy storage and improve the daily capacity factor of the generation system.

Run-of-the-river

Run-of-the-river hydroelectric stations are those with small or no reservoir capacity, so that the water coming from upstream must be used for generation at that moment, or must be allowed to bypass the dam.

Tide

A tidal power plant makes use of the daily rise and fall of ocean water due to tides; such sources are highly predictable, and if conditions permit construction of reservoirs, can also be dispatch able to generate power during high demand periods. Less common types of hydro schemes use water’s kinetic energy or un dammed sources such as undershot waterwheels.

Underground

An underground power station makes use of a large natural height difference between two waterways, such as a waterfall or mountain lake. An underground tunnel is constructed to take water from the high reservoir to the generating hall built in an underground cavern near the lowest point of the water tunnel and a horizontal tailrace taking water away to the lower outlet waterway.
