24 December 2014 year Russian machine builders completed installation of a new power unit at Ulaanbaatar CHPP-4

At the largest in Mongolia Ulaanbaatar CHPP-4 was completed the construction of a new power unit of capacity120 MW. Official ceremony of project transfer to the commissioning stage on December 22 was attended by Dashdorzhiyn Zorigt, Minister of Energy of Mongolia and Iskander Azizov, Extraordinary and Plenipotentiary Ambassador of Russia in Mongolia, as well as representatives of Mongolian Government, who together with the plant's Management estimated quality of the works and readiness of the facility for commissioning.

Ural Turbine Works ( ROTEC Holding) acted as a general contractor and major equipment supplier, and Energy Construction Corporation SOUZ performed construction and installation works at the facility. Having the experience of cooperation with foreign and Russian power machinery building and servicing companies, ROTEC was able to join efforts of many companies for construction of a complex facility within the shortest possible time.

Dashdorzhiyn Zorigt, Minister of Energy of Mongolia, said: "An important phase of construction was completed, and in a very short time. Although according to the international standards similar works require 1.5 years, installation works at CHPP-4 were performed in less than a year."

Some equipment manufactured by Ural Turbine Works is now in operation at the Ulaanbaatar CHPP-4. Over a long period of operation — more than thirty years — these turbines have proved their high reliability and maneuverability. That's why the Management of CHPP decided to install at the plant one more turbine from the same manufacturer.

Construction of foundations for the new power unit began in February 2014, from June to December installation works were carried out in the turbine hall of the power plant between the operating turbines that required high qualification and responsibility of personnel involved in the construction and installation. More than 200 people at one and the same time was occupied in the works. By now the installation works at the power unit have been totally completed: test vacuum was reached and the turbine was brought to barring mode. Completion of commissioning and putting the turbines into operation is planned on early 2015.

As a result, the electric power output of Ulaanbaatar CHPP-4 will be increased by 20%. Generation of heat energy for Ulaanbaatar's consumers will also increase significantly. The service life of the turbine is designed to be 40 years.

Ulaanbaatar CHPP-4 — is the largest energy plant in Mongolia. Owner — Dulaany IV Tsahilgaan. Construction of power plant was started in 1980. Installed capacity — 570 MW, heat energy output — 1050 Gcal/h.
