Kirishskaya GRES put a new turbogenerator into shaft turning

As part of the reconstruction project of the CHP part at Kirishskaya GRES of PJSC "OGK-2", one of the most important stages of pre-start work was carried out — putting the new turbogenerator No. 4 into shaft turning.

Its purpose is to check the correct assembly of the turbine, evaluate the alignment of all elements and the readiness of various systems for start-up. The next key moment — a trial vacuum set — is scheduled for the end of the week.

The replacement and reconstruction of the main equipment of the CHP part of Kirishskaya GRES is carried out within the framework of the state program for competitive selection of modernized capacities (KOMMod).

Shaft turning is the rotation of the turbine by means of an electric drive with a gearbox mounted on it. During the operation, the rotational speed of the turbine rotor is four revolutions per minute. During operation, the turbogenerator rotor will rotate at a speed of 3000 revolutions per minute.

＋ POSITIVE40%

Kirishskaya GRES has achieved a critical milestone by putting the new turbogenerator No. 4 into shaft turning, marking significant progress in the modernization of its combined heat and power (CHP) section. This step verifies the correct assembly and alignment of the turbine, ensuring all systems are ready for startup. The project is part of the state program for competitive selection of modernized capacities (KOMMod), which supports upgrading Russia's energy infrastructure. The successful shaft turning demonstrates effective planning and execution, paving the way for increased efficiency and reliability at the plant. Once operational, the turbogenerator will operate at 3,000 rpm, contributing to the region's energy security. This development highlights the benefits of state-backed modernization efforts in the power sector.

Kirishskaya GRES, a power plant operated by PJSC OGK-2, has carried out the shaft turning of its new turbogenerator No. 4. Shaft turning involves rotating the turbine at four revolutions per minute using an electric drive to check assembly and alignment. This is a standard pre-start procedure before the turbine reaches its operational speed of 3,000 rpm. The work is part of a broader reconstruction of the CHP section under the KOMMod state program. A trial vacuum set is scheduled for the end of the week. The project aims to modernize the plant's equipment, though specific timelines for full commissioning have not been disclosed.

− NEGATIVE20%

While Kirishskaya GRES has completed shaft turning on the new turbogenerator, this is only an early step in a lengthy reconstruction process. The project, financed under the state KOMMod program, may face delays or cost overruns common in large infrastructure upgrades. The shaft turning procedure, though successful, does not guarantee that subsequent stages—such as the trial vacuum set—will proceed smoothly. Furthermore, reliance on state programs raises questions about long-term sustainability and budget efficiency. The plant has not provided a clear completion date for the new unit, leaving room for uncertainty. If issues arise during testing, the modernization could be postponed, impacting regional power supply.
