The joint venture STGT (a project of Inter RAO and Power Machines) has expanded its fleet of serviced high-power gas turbines in Russia and Belarus to 34 units. In 2021, the company serviced 31 turbines.
In 2025, specialists carried out nine major inspections of gas turbines, ten of generators, and five of steam turbines. Additionally, they conducted more than 50 minor inspections and related work.
At the company's production site in the Leningrad region, using its own technology for repairing and restoring the hot section of high-power gas turbines, about 4.5 thousand gas turbine components were restored in 2025, including turbine blades and combustion chamber tiles.
For the first time last year, turbine blades for F-class gas turbines, manufactured according to STGT documentation, were installed at two state district power plants. Intermediate inspections of the blades showed their reliable operation and high quality of production.
In 2025, STGT LLC signed a number of important contracts: among them are long-term agreements for the maintenance of equipment at the Yuzhnouralskaya GRES-2 branch for a period of eight years, with Novo-Salavatskaya CHP for six years, and with TGC-2 for a minor inspection of the gas turbine at the Novgorod CHP.
