Consulting Services, Implementation of Hydropower Projects

Project

The Employer HPSEBL plans to implement the construction of four hydro-electric power plants (HEP). All four small HEPs, namely Devi Kothi HEP (16 MW), Hail HEP (18 MW), Sai Kothi I HEP (15 MW) and Sai Kothi II HEP (18 MW) are designed as run-of-river schemes in the Chamba District in Himachal Pradesh.

In general, except for Sai Kothi II HEP which takes water directly from tailrace of Sai Kothi I HEP and hence has no weir structure, the salient features of the small HEPs are as follows:

• A concrete weir, either drop or gated type
• Waterway structures with desilting basin, headrace tunnel, surge shaft or surface forebay, pressure shaft or penstock, and tailrace
• Surface power houses are foreseen for all four HEPs, generally equipped with Francis turbines (except for HEP Hail, for which Pelton turbines are foreseen) and synchronous generators including 50 Hz 6.6/33 kV transformers and transmission line to the 132 kV HPSEB substation in Nakrore, Chamba District.  

Additional environmental and social investigations were performed to obtain a better understanding on environmental and social impacts of the HEP projects. In particular, an aquatic baseline and impact assessment was conducted for the distinct diversion river stretches to better understand the fish species composition and their habitat needs in order to provide information for the fish pass design as well as the necessary environmental flow to accommodate the fish passage in the dewatered reach. Furthermore, a land acquisition and resettlement action plan (LARAP) has been conducted to detect all project affected persons and lands/ structures and assign compensations to them according to World Bank Standards
