After operating for 72 hours at the average available capacity of 421MW during testing, the unit then proceeded to certification test to confirm performance of its technical parameters.

The commissioning and sale of the units’ capacity is planned to take place before the end of 2013.

Forming a part of Fortum’s ongoing € 2.5bn investment program in Russia, the Nyagan power plant, when completed, will feature three combine-cycle units utilizing energy-efficient gas turbine technology.

The first unit entered commercial operation in March 2013, while the start up of the third unit is scheduled for the end of 2014.

Covered by the Russian government’s Capacity Supply Agreement, Fortum’s investment program covers eight gas-fired units, four of which have already been commissioned.

The remaining four units account for the biggest share of capacity in the program.
