Heat supply issues to be tackled PDF Print E-mail

There are plans afoot to completely decentralize the municipal heat supply system by building new local boiler units with highly efficient boilers in Tashkent.

In 2017-2019, up-to-date, efficient and energy-saving technologies will be introduced into the system, using renewable energy sources. The decentralization schedule provides for the construction of local boiler units in the current district heating systems using solar collectors. 

To date, 65% of all heat networks of the capital are outdated, and 1,761.7 km of pipelines are subject to replacement. It is scheduled to overlay 160 km of pipelines of heating networks annually: 30 km of mains and 130 km of distribution networks. This huge amount of work is unviable today. It is easier to introduce the technologies that are widely used throughout the world.

Therefore, it is envisaged to decentralize the heat supply system of heat source areas. In three years, it is planned to install 1,514 local boiler units and solar stations in Tashkent. The construction will obviate the need to re-lay heat networks, as they will work in closed mode.

It is anticipated that the project will ensure saving 197.9 million cubic meters of natural gas for 40.5 billion soums per year, electricity - 59.7 million kW/h for 9.5 billion soums, and cold water - 22.2 million cubic meters for almost 4 billion soums.

Another innovative project in the heat supply system of the capital comes to the introduction of cogeneration units at HGP-8, HGP-9 and HGP-10. They will ensure the growing needs of the city's economy in electricity and will cover 70.3% of its annual production. Thereby, the provisional saving of natural gas will make 40%.

In 2015, Tashteploenergo built 54 pilot local boiler units in Mirzo Ulugbek and other districts of the capital, which successfully proved themselves in the heating season 2015-2016.


The installed capacity of all boiler units in Tashkent is 6,233 Gcal/hour, the connected capacity is 3,602 Gcal/h. Nearly 9.67 million Gcal of heat energy is supplied annually. Tashteploenergo balance sheet incorporates 1,355 km of heating network channels, including 254.4 km of main networks, and 1,100 km of distribution heating networks.
