36-kV Yedisu Hydro-Solar (Hybrid) Medium Voltage Transmission Line

The project covered the construction of line survey, environmental impact studies, tower plotting, supply of power line goods including galvanized steel, toughened glass support insulators, nuts and bolts, transport, delivery and storage at site, performance, testing, and commissioning of a 36-kV double circuit three phase medium voltage overhead power line using an 477 MCM conductors, which is running from the 7-kilometer Yedisu hydro-solar (Hybrit) power plant to the Kiğı basin switch-yard. 

The project also included the erection of 25 galvanized lattice steel towers and their foundations.  In addition, it involved stringing optical ground wire (OPGW) and overhead static wire (OHSW), and a 7-kilometer line routed through remote, narrow, rugged terrain, and steep mountains.  This complexity in variables required an elevated level of attention and expertise to complete the project in a short period of time.

This project can efficiently transmit electricity from the plants to the national interconnected network with minimal transmission losses while enabling better load balancing and managing voltage drop to ensure grid stability in the region.
