Uzbekistan puts 1602 MVA Halka substation into operation in Tashkent

Uzbekistan energized the new 500 kV Halka substation, with a capacity of 1602 MVA, on November 7. The facility is designed to improve the reliability of electricity supply to Tashkent and part of the Tashkent region, and to reduce the load on existing energy networks.

The substation is one of the country's largest high-voltage infrastructure projects. Its commissioning will redistribute electricity loads in the capital and nearby districts. The load on the Tashkent Thermal Power Plant is expected to fall, which, according to the information provided, would allow the plant to stop using fuel oil (mazut). The project is therefore also aimed at improving the environment by cutting pollutant emissions into the atmosphere.

The total cost of the project, implemented with the participation of the World Bank, is $171.4 million. Along with the substation, 213 km of 220 kV and 72 km of 500 kV overhead power lines were built, bringing the total length of new high-voltage lines to 285 km. The infrastructure will expand transmission capacity within Uzbekistan's unified power system. Final work to fully integrate the new facilities into the national grid is ongoing.
