Hydel power generation from the projects affected by rains and floods in Uttarakhand and Himachal Pradesh has been restored, according to an official.
Due to heavy landslides many Hydro Electric Projects had stopped work on account of high silt content in water.
“No project was stalled due to floods. Our’s is a storage project and the catchment area is big so there wasn’t so much problem,” THDC India official said.
The company in a statement said: “Due to recent heavy rainfall in Uttarakhand the water inflow in Tehri dam from Bhagirathi and its tributaries reached about 7,000 cumecs, of which a mere 500 cumecs was released from Tehri Dam Reservoir and remaining 6,500 cumecs of water stored in the reservoir.”
Cumec is a measure of the rate of flow of fluid, especially through a pipeline, equal to one cubic metre per second.
Tehri reservoir recorded the rise of 25 meters within 48 hours of rainfall on 16-17 June, the statement said.
On June 16, Alaknanada and Bhagirathi had a combined flow of around 13,000 cumecs at Haridwar out of which only 500 cumecs of Bhagirathi water was released from Tehri Dam Reservoir.
“In case the whole of the water inflow of Bhagirathi would have been released from the Tehri Reservoir it could have caused an additional rise in the water level,” it added.
SJVNL, which operates Nathpa Jhakri Hydroelectric Station of 1,500 MW capacity, was stalled due to higher silt level on June 18-19. “This situation was mainly due to higher silt levels,” SJVNL official said.
State-run NTPC’s Dhauliganga project in Uttarakhand was also affected. However, the company said that normalcy has been restored at the site.
