Deputy Prime Ministers of Russia and Mongolia Launched a New UTW Turbine at the Ulaanbaatar CHPP-4

3 September 2019

On September 2, 2019, Ulaanbaatar (Mongolia) saw the launch of the T-123 turbine during the solemn ceremony. It is the first of four plants retrofitted by the Ural Turbine Works (part of ROTEC) at the Ulaanbaatar CHPP-4. The new turbine unit was commissioned by the Deputy Prime Ministers and Co-Chairs of the Russia-Mongolia Intergovernmental Commission on Trade, Economic, Scientific, and Technical Cooperation Alexey Gordeev and Ölziisaikhany Enkhtüvshin.

The launch of the T-123 turbine heralded the completion of the first of three upgrade stages at the CHPP-4, the scope of responsibility assumed by ROTEC and the Ural Turbine Works. The upgrade helped completely renew the turbine's service life. Now, instead of decommissioning, the plant will operate for at least 40 years. The capacity of the upgraded turbine is 123 MW. It will provide power and heat for 25 and 70 thousand households, respectively. An increase in efficiency of 9% has improved the cost-effectiveness of the turbine. The level of harmful emissions was reduced by 10%. The maneuverability of the new unit has increased by 40%, which reduces load fluctuations and helps avoid emergency shutdowns in winter.

The second stage of the work involves the upgrade of the PT-100 turbine with the completion scheduled for October this year. The third stage will include the upgrade of two more units with the capacity of 123 MW each. The completion of all activities is scheduled for Q3 2020.

In total, UTW will supply equipment with a total capacity of 469 MW to Mongolia, which is 59 MW more than the current installed capacity of the plant. Thus, the capacity of CHPP-4 will be upgraded by 592 MW (together with the Ural turbine supplied in 2015). This makes up about 60% of the total capacity of the Mongolia’s power generating system.

“We all know that without the energy industry it is impossible to ensure not only development, but also decent life for people, to run enterprises and the infrastructure. The previous turbines operated for several decades and we are happy that they were all supplied by our country. However, it is even more pleasing that today's upgrade also involves our units and our turbines. This will further strengthen the energy industry of Mongolia. This is why October next year is a crucial deadline for the company and everyone involved in the project to finish the upgrade of all four turbines. Today, we should congratulate and thank everyone who participated in this event – project designers, installation personnel, builders, and, of course, the CHPP-4 team. Thank you for your work! I hope that the upgrade of the CHPP-3 will also use our Russian turbines,” says Alexey Gordeev, Russia's Deputy Prime Minister.

The Ural Turbine Works has helped us increase the capacity of the CHPP-4 by 64%, add 220 thousand hours to the turbine service life, and reduce coal consumption by 100 thousand tons. The population and enterprises of Central Mongolia now enjoy stable supply of heat and power. I would like to thank the Ural Turbine Works for the implementation of this project and wish the CHPP-4 team all the success. The team works hard every day to ensure energy security and stable economic growth of their country. Thank you!” says Ölziisaikhany Enkhtüvshin, Mongolia's Deputy Prime Minister.

“I would like to thank the staff of the Ulaanbaatar CHPP-4, we have been working together for quite a number of years; we completed the first project in 2015, and we are commissioning the first turbine as part of the new project today. On behalf of the Ural Turbine Works, I can say that this station is one of the most comfortable places for work that I have ever seen. As the head of the station, Mr. Temerhuyag, has rightly pointed out, this is not the customer/contractor work, but a truly joint project. It is the great honor for us to bring warmth and light to the residents of Ulaanbaatar and the whole of Mongolia. I would like to express my special gratitude to the Ambassador Extraordinary And Plenipotentiary Of The Russian Federation To Mongolia Iskander Kubarovich Azizov and the Head Of The Trade Mission Maxim Viktorovich Vasilyev, who help us at every stage of the project. I also like wish all the success to the station's staff and all of us once again!” notes Mikhail Lifshitz, Chair of the B of D, the Ural Turbine Works.

In 2015, ROTEC and the Ural Turbine Works completed a project to expand the CHPP-4 in Ulaanbaatar, installing a new 123 MW turbine unit in the cell among the operating turbines within the shortest timeframe. As a result, the capacity of the entire power system of Mongolia increased by 15%, whereby the country's growing demand for energy resources was satisfied until 2018. A memorandum of cooperation under the project focused on the upgrade of the first four turbo-generators of the station mounted in the 1980s was signed on June 1, 2017 at the St. Petersburg International Economic Forum and witnessed by the Prime Minister of Mongolia Jargaltulgyn Erdenebat and Minister of Energy Purevjav Gankhuu.
