Power line construction up to 500 kV: overhead and cable lines
Foundations, tower erection, conductor, earth wire and OPGW, cable lines and substation connections. Our portfolio covers 35 to 500 kV lines across Uzbekistan.
Power lines up to 500 kVPower lines up to 500 kV
Before 2025 GRIDCON built 236.6 km of 110–220 kV lines for NEGU JSC in the Kashkadarya, Namangan, Samarkand, Navoi and Syrdarya regions. The highest-voltage line in the portfolio is the 40 km double-circuit Nurabad — Khalqa 500 kV overhead line for ACWA Power in the Samarkand and Jizzakh regions.
For 2026–2027, 134 km of 220 kV lines are in design in the Fergana Valley under a World Bank project (REMIT). We build cable lines in dense urban areas: the 110 kV cable line of the Iyk Ota substation and the 53 km Sagbon — Tashmi 35 kV cable line in Tashkent.
