Construction of the 500 kV Sarimay–Djankeldy Transmission Line and the Loop-In/Loop-Out Line Connecting the Bash WPP to the New 500 kV Navoi–Muruntau Open Switchyard Along a 28.55 km Section, Uzbekistan
General Project Information:
The project comprises the construction of the 500 kV single-circuit Sarimay–Djankeldy overhead transmission line between the Khorezm and Bukhara regions, as well as a loop-in/loop-out line connecting the new 500 kV Bash WPP open switchyard to the existing 500 kV Navoi–Muruntau transmission line. The project also includes the expansion of the Sarimay substation to the 500 kV voltage level.
The project is aimed at improving the reliability and stability of the national power system, enabling the evacuation of power generated by new wind power plants in the Bukhara Region, and supporting the integration of renewable energy sources into Uzbekistan’s national power grid.
