Progress continues at 444-MW Vishnugad Pipalkoti hydroelectric project

According to the World Bank, construction continues on the 444-MW Vishnugad Pipalkoti hydroelectric project (VPHEP) on the Alaknanda River, a major tributary of the Ganga River, in the district Chamoli in Uttarakhand, India.

THDC India Ltd., formerly Tehri Hydro Development Corp. Ltd., is the project developer and is scheduled to complete the US$922 million facility by December 2017.

In a press release the World Bank said, “The excavation of the upper strata of the diversion tunnel is complete and work on the lower strata is in progress. Works on the access tunnels to the water intake channel, the desilting chamber and the headrace tunnel (HRT) are also underway.”

The approach road to the tunnel boring machine (TBM) platform is complete and preparatory work on the TBM platform is progressing with the TBM delivery and assembly scheduled to be completed in February 2016.

VPHEP is a run-of-river scheme that includes the concrete gravity dam, an 8-mile-long headrace tunnel, an underground powerhouse that will contain four 111 MW vertical Francis turbine generating units and the 2-mile-long tailrace tunnel.

A panel of international and national experts on technical and environmental and social matters visited the project site in February 2015.
