en.Wedoany.com Reported - Modern Gas Turbine Technologies (STGT) has signed a six-year service contract with the Nyagan Thermal Power Plant, covering maintenance work on three units at the station. According to a press release from STGT's press office, the agreement stipulates that experts will conduct regular equipment inspections and supply new spare parts.

The Nyagan Thermal Power Plant, located in the city of Nyagan in the Khanty-Mansi Autonomous Okrug (Yugra), is one of the largest thermal power plants in the world, with an installed electrical capacity of 1,361 MW. The plant uses natural gas as its primary fuel and supplies electricity to Yugra, Yamal, Tyumen Oblast, and the Ural region.

Under the terms of the contract, STGT will conduct regular inspections of power generation equipment: including 14 minor inspections, 3 major inspections to extend gas turbine life, 3 major steam turbine inspections, intermediate generator inspections, as well as inspections of process control systems and electrical equipment. Additionally, the company will supply three sets of new turbine blades and perform restorative repairs on components that have exhausted their service life.

STGT's cooperation with the Nyagan Thermal Power Plant began in 2013. Between 2015 and 2017, the company upgraded three gas turbines to the 8th generation, increasing the units' power and efficiency while reducing carbon dioxide emissions. This project became one of the unique cases in global practice, being among the first such upgrades carried out directly at a power plant.
