The Dhupdal Hydropower Project is a 2 x 1400 kW canal based installation located at Dhupdal in Belgaum district of Karnataka. The project utilises irrigation releases of approximately 68 m³ per second from the Dhupdal reservoir, discharged into the Ghataprabha left bank canal through a head regulator.

Water is conveyed from the reservoir to the powerhouse through an intake channel excavated in rock within the lake bed. After power generation, flows are returned to the irrigation canal through a short tailrace. To enhance generation potential, modifications were carried out to the canal, including widening works, which increased the available head from 1.80 m to 5.1 m. The first unit was commissioned in January 1997 and the second unit in February 1997.

TCE’s scope

TCE provided comprehensive engineering services for the project, including preparation of the detailed project report and detailed design engineering for civil, hydro mechanical and electrical systems. TCE was responsible for construction supervision at site, inspection and expediting of equipment and works, and support during commissioning of both generating units.

Impact

The project achieves an estimated annual generation of 14.0 million units. Each unit is equipped with a full Kaplan S type turbine designed for a rated discharge of 23 m³ per second, operating at a rated head of 4.80 m and a rated speed of 158 rpm. The project demonstrates effective utilisation of irrigation releases for decentralised hydropower generation.
