| Project Detail |
The project consists of a dam, pressure tunnel, surge tank, penstock and powerhouse. Additionally a transfer tunnel will convey the water from Nakra river to the new Nenskra dam reservoir to improve the performance of the Project. An asphalt faced rockfill dam (AFRD) has been selected considering the site conditions in the Nenskra river basin. The peculiarity of the structure is the 65 m deep Cut-Off wall to be realized throughout the alluvial deposit on the river bed.
The other main ancillary structures to the dam are:
The Bottom Outlet structure (tunnel with gate shaft)
The Spillway Structure (tunnel with lateral over flow structure and unlined plunge pool)
The project is capable of providing on average total energy generation of 1219 GWh/y, 259,2 GWh of guaranteed supply in the winter months and maximizes export benefits in the summer months. The power will be distributed through a 220 kV transmission line to Akhari-Jvari substation
