Stable Electricity and Heat Supply Ensured in Tashkent for Autumn-Winter Period

Tashkent, Uzbekistan (UzDaily.com) — In 2025, Tashkent’s thermal power plants and heat centers carried out a comprehensive set of measures to ensure uninterrupted electricity and heat supply for residents and social facilities during the autumn-winter period. Extensive preparatory and modernization works were undertaken to strengthen energy security and improve environmental performance.

Modernization of Tashkent Thermal Power Plant (TTPP)

At TTPP in Yakkasaray district, five boiler units and one gas turbine unit were overhauled. The plant has completely phased out fuel oil, now generating electricity and heat exclusively from modern gas installations.

Following a presidential directive, two new gas turbine units with a capacity of 64 MW each were commissioned at the heat plant in 2024, resulting in:

Reduction of annual pollutant emissions by 200 tons;

Additional generation of 515 million kWh of electricity and 630 Gcal of heat per year.

The plant implemented four automatic environmental monitoring stations and one eco-post, and gas networks were upgraded with new mechanical filters. A “green belt” around the TTPP was created on 15.5 hectares with 16,490 fruit and ornamental trees to improve urban ecology.

Upgrades to Tashkent’s Thermal Infrastructure

Within JSC “Thermal Power Plants,” 13 boilers were fully overhauled, and 47 boilers across nine heat centers of the Tashkent Heat Center received routine maintenance. Total capacity reaches 4,580 Gcal, providing heat at 60–85°C throughout the season.

Six centers have installed absorption gas filtration systems adapted for fuel oil boilers, along with devices for removing solid impurities from fuel oil.

New Gas-Piston Power Plant — Eliminating Fuel Oil

At the 4th heat center, a new 100 MW gas-piston power plant, implemented jointly with CNTIC, Vpower Holdings Singapore Pte. Limited, and Cntic Vpower Thermal Energy, is scheduled to launch by year-end. Benefits include:

Creation of 50 new jobs;

Annual production of 876 million kWh of electricity and 784,000 Gcal of heat;

Savings of 15 million cubic meters of natural gas.

The station will supply electricity to 365,000 households and heat to 58,000 households in the capital.

Environmental Projects and Efficiency Improvements

TTPP, one of the country’s largest plants, has an installed capacity of 2,230 MW, generating an average of 20 million kWh daily. In 2025, a new “Yengli Filter” flue gas cleaning system for Units 1 and 2 was commissioned, with a capacity of 1.5 million m³/hour and 99.5% efficiency, reducing particulate emissions from 100 mg/m³ to 6 mg/m³.

Additional environmental benefits:

110.7 tons of emissions prevented via solar panels and water heaters;

350,000 m³ of drinking water saved through use of technical water for heating.

Modern automatic monitoring systems were installed on three chimneys to provide round-the-clock emission control.

Combined-Cycle Unit: Fuel Savings and Increased Output

A 370 MW combined-cycle unit launched in December 2017 significantly reduced fuel consumption from 370 g to 223 g per kWh, saving 350.9 million cubic meters of gas annually and enabling additional generation of:

2.6 billion kWh of electricity per year;

110,000 Gcal of heat.

Currently, 97% of TTPP’s output is electricity, with the remainder delivered as heat to organizations, residential buildings, and nearby greenhouses.
