17 December 2019 year Ural turbine successfully passes comprehensive testing at Ulan Bator CHP-4

Comprehensive 72-hour tests of the upgraded 100 MW turbine have been successfully completed at Ulan Bator CHP-4 (Mongolia). The turbine unit relayed the declared parameters to the network. The turnkey work was carried out jointly with ROTEC JSC in record time, i.e. within 11 months and 8 days from the advance date. The PT-100 turbine is the second of four units modernized by Ural Turbine Works JSC at Ulan Bator CHP-4.

During modernization, the turbine, which has been running at the station since 1983, received an additional 20 MW, and its thermal load was increased by 40 Gcal/h. The unit’s fleet life was completely updated; now, it will be able to run for at least another 30 years. It’s worth noting that when working on the project, UTW JSC used the experience of the PT-60 and PT-80 turbine modernization projects, which had been previously completed by the plant for Russia, Kazakhstan and Belarus.

UTW JSC also supplies auxiliary equipment for all four turbines, thus acting as a complete supplier.

As you may recall, the first of the (T-123) turbines modernized at Ulan Bator CHP-4 was launched in September 2019 in the presence of Deputy Prime Ministers and Co-Chairs of the Russian-Mongolian Intergovernmental Commission on Trade, Economic and Scientific-and-Technical Cooperation, Alexey Gordeev and Ölziisaikhany Enkhtüvshin. Two more T-123 units are now being installed at the station. An ambitious project to upgrade the generating equipment of Ulan Bator CHP-4 will be completed in 2020.

In total, UTW JSC will supply equipment with 469 MW in total capacity to Mongolia, which is 59 MW higher than the station’s current capacity. Thus, CHP-4 will be upgraded to 592 MW (together with the Ural turbine, delivered in 2015). This represents roughly 60% of the total power of Mongolia’s power system.

In 2015, ROTEC JSC and Ural Turbine Works JSC implemented a project on the expansion of Ulan Bator CHP-4, installing a new 123 MW turbine unit in the cell among operating turbines in record-short time. As a result, the capacity of Mongolia’s entire power system has been increased by 15 percent, having resolved the country’s growing energy demand until 2018. A Memorandum of Cooperation on the modernization project for the station’s first four turbine generators installed in the 1980s was signed on June 1, 2017, at the St. Petersburg International Economic Forum in the presence of Prime Minister of Mongolia Jargaltulgyn Erdenebat and Minister of Energy Purevzhavyn Ganhuu.

Ural Turbine Works JSC ( is one of the leading Russian machine-building plants designing and manufacturing power-generation equipment. UTW was founded in 1938 and is focused on the production of steam turbines, as well as on the servicing and modernization of steam and gas turbines. It has significant successful experience in supplying power equipment on the international market, including for the power-generating enterprises of Belenergo SPA. The company is a member of ROTEC.
