ON RIVER ALAKNANDA
The Vishnugad Pipalkoti Project has been designed as a 444 Megawatt, run-of-river hydropower generation scheme which, when completed, will generate approximately 1,800 Gigawatt-hours, (or million kilowatt-hours) of energy in a typical dependable year, representing a valuable addition of peaking power to India’s Northern grid, which faces severe power shortages at peak consumption times.
In order to maintain the water flow needed for power generation, the Project will build a 65-meter diversion dam to create a small reservoir in the Alaknanda gorge. This reservoir will store about 3.63 million cubic meters, the equivalent of about 4.9 hours of average flow of the river waters. A 13.4-kilometer head race tunnel will carry the water to an underground powerhouse which will generate the power.
