In May, ROTEC professionals started servicing 450 MW CCGT units at Pravoberezhnaya CHP in Saint Petersburg and CHP-21 in Moscow. The company services the four GTE-160 type gas turbines under long-term 10-13-year service contracts.
ROTEC professionals are currently carrying out an overhaul on the generator and minor inspection of gas turbines at Pravoberezhnaya CHP. A 450 MW combined-cycle gas turbine unit is one of the most state-of-the-art power units that have been in operation in the Northern capital since November 2012. It consists of two GTE-160 gas turbines, two heat recovery steam generators and one steam turbine. This is the first time servicing is performed on the new gas turbines.
From May 14, minor inspection has also been carried out on the hot gas path of the similar power unit of Moscow CHP-21. This power plant's CCGT unit was commissioned in 2008, and as of now, the turbines have already run for over 42,000 equivalent hours. During the next scheduled works the turbines will undergo a technical status check.
ROTEC won a tender to service these power units as a subcontractor under the contract with TER-Servis who acts as the general contractor under service agreements for the power plants owned by Gazprom EnergoHolding.
In total, ROTEC's portfolio of long-term service contracts covers 25 gas turbines of different unit sizes and aggregate capacity of about 3 GW.
