First Russian 32 MW engine for gas pumping presented to gas industry specialists

ST. PETERSBURG. Oct 7 (Interfax) - The United Engine Corporation (UEC) has developed a new industrial engine, the NK-36ST-32, Rostec state corporation said.

This is the first domestic design with a capacity of 32 MW for gas transportation through main pipelines. A prototype of the engine was presented to a wide professional audience at the 14th St. Petersburg International Gas Forum. UEC first showed the NK-36ST-32 engine in September, when President Vladimir Putin visited the Samara-based manufacturer UEC-Kuznetsov.

The engine was created on the basis of the serially produced NK-36ST-25 with a capacity of 25 MW using modern technologies and solutions. The design continuity with the base NK-36ST-25 engine will minimize the cost of modernizing existing compressor stations.

Today, one of the most in-demand units in the gas industry are installations with a capacity of 32 MW. Previously, there were no domestic developments in this class, the corporation said. The Nevsky Plant produces a 32 MW turbine, but this is a localized version of a foreign design at a Russian production facility.

"The creation of the new engine will solve the issue of import substitution, which opens up new opportunities for developing Russia's gas industry," Rostec quoted the state corporation's executive director Oleg Yevtushenko as saying.

The new development has increased power and high efficiency - 38%. According to these characteristics, it surpasses all Russian gas turbine engines for gas transportation through main gas pipelines, Rostec said. The new unit also has reduced fuel consumption per unit of power of no less than 6%, as well as a high designated service life of 120,000 hours. An important advantage of the NK-36ST-32 is its environmental friendliness, as it is equipped with a low-emission combustion chamber. Its use ensures compliance with all environmental standards.

In September 2025, the NK-36ST-32 prototype successfully passed the first stage of comprehensive factory tests. During these tests, the engine reached its rated capacity of 32 MW and confirmed its stated technical characteristics.

UEC-Kuznetsov designers are developing a modification of the NK-36ST-32 for Russia's southern regions. It will be capable of operating in extreme conditions - at temperatures above 40 degrees Celsius and in high mountains.
