The company’s history began in September 1926, with the creation of Kotloturbina Kiev design & installation enterprise, the all-Ukrainian branch of Teplo i Sila (“Heat and Power”) joint-stock company. 

In 1939, the Kiev design and installation enterprise affiliated to the YuzhEnergoStroy local construction trust, Kharkov, and in 1940 it was renamed the Kiev TeploEnergoMontazh enterprise. During the period from 1926 to 1940 the enterprise installed and put into operation equipment at power facilities of Ukraine, Belarus and Russia with a total capacity of 187 MW. 

In July 1941, the company was evacuated to the city of Chelyabinsk, renamed ChelyabEnergoMontazh and transferred into the UralEnergoStroy trust. Altogether during the period from 1941 to 1943, in the Ural region the company commissioned 365 MW of generating capacities at power plants in the cities of Chelyabinsk, Magnitogorsk, Karaganda, Orsk, Ufa, Orenburg, Kopeysk, Troitsk.

In December 1943, the company returned to Kiev and in April 1944, the KievPromEnergoMontazh State Union Construction & Installation Trust was formed on its base, which in April 1958 was renamed as the YuzhTeploEnergoMontazh State Union Construction & Installation Trust.

In March 1991, YuzhTeploEnergoMontazh State Union Construction & Installation Trust was transformed through corporatisation into PivdenTeploEnergoMontazh joint stock company (Yuzhteploeneromontazh is a Russian spelling of the company name, under which it was widely-known during the Soviet time and that originated the company abbreviated name "UTEM”, commonly used up to now).

In March 2009, a legal form of the company was changed into the PivdenTeploEnergoMontazh public joint-stock company.
