Inspection works included the repair of several key components of the power unit, notably components of the combustion chamber. The overhaul extends the overhaul interval of the SGT 800 turbine by 25%, which is equivalent to approximately seven months of operations.
The 519 MW power plant, one of the largest in Bashkortostan, provides heat to more than half of the residents and industrial facilities in city of Ufa, with more than 1 million inhabitants. The upgraded plant allows the operator Bashkir Generation’s better cope with Russia’s winter season, which typically lasts from October until May.
Use of localized resources
Onsite works were carried out by the GE Energy Technology Center in Kaluga, situated some 150 kilometers south of Moscow.
“Completion of such a comprehensive inspection project at the TPP-2 plant in Ufa was delivered through the collaboration of GE’s Cross-Fleet Solutions team, the repairs team in Birr, Switzerland, and the field services execution arm FieldCore,” said Michael Rechsteiner, Vice President for Europe at GE Gas Power. He underlined the use of localized resources made it possible to organize this task in the most time-efficient way.
Spare parts warehouse in Kaluga
GE’s Cross-Fleet Solutions offering provides an increase of maintenance intervals for Siemens’ SGT-800 units of up to 40,000 hours/900 starts, enhancements to plant output by up to 6% and efficiency by up to 1.5% (depending on the turbine rating). Most of the maintenance is carried out in the GE Energy Technology Center in Kaluga, where GE also has a localized SGT-800 spare parts warehouse to ensure the availability of its key components and provides the possibility of replacing them promptly – up to within 24 hours.
GE’s presence in Russia, especially in Kalgua, is crucial for regional customers. In 2018, GE managed to bring an SGT-800 unit at Ufa TPP-2 back online within 24 hours and subsequently won a multiyear service contract with Bashkir Generation Company.
