The Nyaganskaya GRES combined cycle gas turbine (CCGT) power plant is located on a greenfield site near the city of Nyagan, in the Khanty-Mansi Autonomous District of Western Siberia, Russia.

The 1,254MW power plant, comprising of three 418MW units, is being developed by Fortum Corporation. The engineering, procurement and construction (EPC) contract for the project was awarded to E4 Group in July 2009 and was valued at RUB13bn (approximately $408m).

Nyaganskaya GRES is the principal project of the €2.5bn ($3.4bn) investment programme being implemented by Fortum in Russia. The programme constitutes the installation of eight combined-cycle gas units with a combined capacity of approximately 2,400MW, of which five have already begun operations.

"The first unit of Nyaganskaya GRES was commissioned in March 2013 and the second unit was commissioned in December 2013."

The first unit of Nyaganskaya GRES was commissioned in March 2013 and the second unit was commissioned in December 2013. The third unit is slated for commissioning by the end of 2014.

Estimated to cost €1.4bn ($1.93bn), Nyaganskaya GRES is considered to be the biggest thermal power plant in Russia by investment. The plant’s full output will be sufficient to meet the power needs of about 3.1million households in eastern Siberia and the Polar Urals.

Nyaganskaya GRES power plant details

"The plant is fitted with a SGT5-4000F single-shaft combined-cycle gas turbine (CCGT) and a SST5-3000 steam turbine. "

The plant is fitted with a SGT5-4000F single-shaft combined-cycle gas turbine (CCGT) and a SST5-3000 steam turbine. Three horizontal heat recovery steam generators (HRSG) rated at 607t each, and ancillary equipments have also been fitted.

The natural gas-fuelled power plant is located at latitude of approximately 60° north. The average annual temperature at the site is -3°C.

The project incorporates advanced fuel-saving technologies and use of highly efficient combined-cycle process in order to meet the stringent environmental regulations and tackle the harsh conditions.

Three turbine hall cranes, one for each unit, are engaged at the project site. The cranes, supplied by Konecranes, have a lifting capacity of 336t from the main hoist, in addition to two auxiliary hoists with lifting capacities of 23t and 1.8t respectively. Two jib cranes equipped with Konecranes XM hoists are also placed in each turbine hall.

The water required to run the plant is being sourced from Nyagan-Yugan River.

Power transmission and distribution from Nyaganskaya GRES

The groundwork for power distribution from the Nyaganskaya GRES power plant began in 2011 under an agreement of cooperation between Federal Grid Company (FGC) and authorities of Tyumen Region, Khanty-Mansi, and Yamalo-Nenets Autonomous Districts.

The scheme includes the laying of 220kV and 500kV bused approach lines to the plant. The 500kV line is the 41km long Ilkovo-Lugovaya line comprising of two sections: Ilkovo -Nyaganskaya GRES and Nyaganskaya GRES-Lugovaya.

The 220kV line is from Krasnoleninsky Gas Processing Plant to Ilkovo measuring 35km long and divided into two sections namely Ilkovo-Nyaganskaya GRES and Nyaganskaya GRES-Krasnoleninsky Gas Processing Plant.

The power generated by the third unit will be distributed through the 142km long, 22kV Nyaganskaya GRES-Kartopya overhead transmission line, which is currently in design phase.

Contractors involved with the Nyaganskaya GRES project

ZAO Tepingeneering designed the combined cycle steam-gas turbines, whereas Siemens supplied the CCGT turbines. The three horizontal heat recovery steam generators (HRSG) were supplied by Taganrog Boiler-Making Works Krasny Kotelshchik.

The boilers were designed by PJSC Engineering Centre EMAlliance-BSDB BP (Barnaul) and constructed at PJSC TKZ Krasny Kotelshchik.

The 500kV/220kV switchyard at Nyaganskaya GRES was designed by PIC UralTEP.
