Improved Operational Flexibility

  • Well suited for combined-cycle applications, with 99.8 percent average reliability and 95.1 percent average availability(1)
  • Advanced Dry Low NOx (DLN) 2.6+ combustion system enables 25 ppm NOx emissions
  • Turndown to 38 percent of baseload within emissions compliance
  • Fast start reduces time across the entire start sequence, up to 20 minutes less in combined cycle, lowering startup emissions
  • Enhanced compressor increases reliability and availability and reduces periodic inspections and maintenance costs
  • OpFlex* AutoTune improves DLN operability, increasing range of natural gas compositions that can be used and improving cold day performance

Enhanced Architecture for Performance and Reliability

  • Inlet guide vane enhancements dramatically reduce degradation and stress on wear-related components and lengthen compressor life cycle
  • Three-stage hot gas path (HGP) turbine has Advanced Gas Path features, and improved materials provide cooling and longer parts durability
  • Mark* VIe Control System real-time physics-based modeling increases overall performance, operability, and reliability
