The running time of the engine at the Lida thermal power plant has reached the indicator of the inter—repair life - 25 thousand hours.
Specialists of the United Engine Corporation of Rostec State Corporation will carry out major repairs and modernization of the NK-37 power engine at the Lida CHPP in Belarus by the beginning of 2027. Work has already begun on updating the main parts, including the elements of an environmentally friendly low-emission combustion chamber. The project is being implemented under a cooperation agreement between the Government of the Republic of Belarus and Rostec State Corporation.
The 43 MW power plant meets the needs of the Lida region of the country for heat and electricity. The GTE‑25/NK gas turbine power plant based on the NK-37 was put into operation at the facility in 2008. In 2011, this engine was first equipped with a low-emission combustion chamber, which improves environmental performance, and an automated fuel supply control system. The upgraded NK-37 has successfully passed pilot operation and continued to operate as part of the CHP.
To date, the running time of the engine at the facility in Belarus has reached the indicators of the inter-repair life, which is 25 thousand hours. As part of the maintenance, ODK-Kuznetsov specialists began work on the planned overhaul and modernization of the industrial engine.
"Lida CHPP is of particular importance in the context of strategic cooperation between the Republic of Belarus and the Russian Federation. Many years of experience in operating the NK-37 engine confirms its high efficiency and reliability. The engine is being upgraded as part of the overhaul. Specialists update the main parts and assemblies that have reached their end of life during operation. The parts of the low-emission combustion chamber responsible for environmental performance are being replaced. The support part is also being finalized, housings and bearings are being replaced with more modern and reinforced ones, and new sensors are being installed to monitor the condition during operation. These measures will increase the reliability of the NK-37 engine. The work will be completed in early 2027," said Andrey Vorobyov, General Director of UEC Engineering.
The NK-37 engine with a capacity of 25 MW was developed and manufactured at the Samara-based ODK-Kuznetsov enterprise. It combines high efficiency, reliability and low operating costs. The automatic start-up system, high pre-start readiness, and the ability to operate in automatic mode make it possible to use power plants with the NK-37 engine both in normal power generation mode and when compensating for peak loads in emergency situations. The total operating time of the NK-37 engines in Russia and abroad exceeded 230,000 hours.
ODK Engineering is a comprehensive supplier of gas turbine equipment manufactured by UEC enterprises and the organizer of repair and maintenance work. Based on the NK-37 engine, a fundamentally new line of energy equipment is currently being created — pre-built gas turbine power plants (GTES) with a capacity of 25 MW and 32 MW. Due to the high specific capacity and compact dimensions, modular GTES can be deployed in energy-deficient areas as soon as possible.
The Lida Thermal Power Plant is located in the Grodno region of the Republic of Belarus and provides electric and thermal energy to the cities of Lida and Smorgon. The main generating equipment is the GTE—25/NK power plant based on the NK-37 gas turbine engine.
