Located on the Sarbari River in the Kullu District of Himachal Pradesh, India, this small-scale run-of-river project consists of two 2.25MW turbines to supply zero-emissions renewable electricity to the state grid – Himachal Pradesh State Electricity Boards (HPSEB).

Sarbari Run-of-River Hydro Project

Sarbari Run-of-River Hydro Project

Emission reductionsThis run-of-river hydro plant reduces CO2 emissions by displacing electricity generated from fossil-fuel based plants. India’s electricity generation currently relies heavily on the use of coal but small-scale hydro plants do not incur the local environmental pollution or solid waste problems associated with coal-fired stations.

Community BenefitsIn addition to the environmental benefits, the project has also contributed to the local economy and livelihood of residents through the creation of jobs – 17 employees are currently working full time in the plant while approximately 250 others were hired for the planning, construction, and commissioning. 

The Technology: Hydroelectric power, or hydro power, is electricity generated from the energy of moving water.  There are several types of hydroelectric facility, including impoundments, run-of-river and pumped storage.  Impoundments and run-of-river projects are both powered by the kinetic energy of flowing water.  However impoundments use large reservoirs to restrict the flow of water while run-of-river projects use the natural flow of waterways. A pumped storage hydro facility produces electricity by moving water between reservoirs at different elevations during peak times. The energy produced primarily depends on the volume of water and the height difference between the water source and the turbines.
