Siemens and Fortum have signed a long-term service contract for the Nyaganskaya GRES combined cycle power plant in Nyagan, Russia. The power station consists of three combined cycle power units totaling 1,254 megawatts (MW).

The first unit, with a capacity of 420.9MW, began commercial operation in April 2013. The commercial operation of the second unit began at the end of 2013, and the third unit is currently under construction.

Under terms of the long-term agreement, Siemens will provide service and maintenance for the gas turbines, steam turbines and generators of all three combined cycle plants for a period of six years.

“As one of Russia’s largest combined cycle power plants, Fortum’s Nyaganskaya power plant plays an important role in contributing to the region’s energy supply,” said Alain de Cat, Head of Siemens Energy Service Fossil, Region Europe and Africa. “With our new regional hub in St. Petersburg, Siemens will have the resources and technical abilities available nearby to help ensure the plant operates with high availability, reliability and economic efficiency.”

Siemens supplied its SCC5-4000F power train solution consisting of an SGT5-4000F gas turbine, SST5-3000 steam turbine, SGen5-2000H generator and SPPA-T3000 automation system for each of the three units of Nyaganskaya GRES. Earlier this year after the successful Kirishi repowering project, Siemens also signed a long-term service agreement for the Kirishskaya GRES power plant in the Leningrad region. Together, these steps are positioned to support the continuous improvement of the overall efficiency and reliability of the Russian power supply.
