Nineteen Substations and Thirty-Two Power Lines to Be Upgraded in Tashkent in 2025

Tashkent, Uzbekistan (UzDaily.com) — In 2025, Tashkent is implementing a large-scale program to repair and modernize its substations and power transmission lines.

According to Bobur Islamov, First Deputy Chairman of the Board of Regional Electric Networks (RES), who spoke at a press conference on November 6, the works cover 19 substations and 35–110 kV transmission lines connecting 32 substations across the city.

Islamov noted that Presidential Decree No. PP-91 and Cabinet of Ministers Resolutions No. 259 and No. 598 outline measures to improve the capital’s electricity supply. “Due to the sharp increase in the number of consumers and the volume of consumption, our networks and substations are operating under high load. Therefore, the task was set to modernize them,” he said.

RES is carrying out work simultaneously at several substations. Modernization is underway at the Yunusabad, Botanika, and Sagban substations in the Almazar district. Islamov emphasized that the work at Yunusabad will be completed within 15 days, while the modernization of Botanika and Sagban is expected to be finished by the end of the year. Any temporary power interruptions, he added, are resolved within an hour and a half.

“Building a new substation is easier than modernizing an old one. It’s a labor-intensive process — we have to shut down one line or transformer, which increases the load on the remaining equipment. We try, whenever possible, to keep existing transformers running while simultaneously constructing new substation units,” he explained.

Under the 2025 program, 19 substations, 16 power lines, and 35–110 kV networks connecting 32 substations are being upgraded. The Tashkent city administration has allocated 60 billion soums for these purposes, which will be used to renew 326 kilometers of transmission lines and 47 transformers. Islamov noted that many of these works had not been carried out for years, and accumulated issues are now being systematically addressed.

A new large-scale program is already planned for 2026: modernization will cover 21 substations and 19 power lines, further strengthening the reliability of the capital’s power supply system.
