The next level of efficiency and performance
With our HL-class gas turbine we are paving the way to the next level for higher power plant efficiency and performance. This evolutionary development step, derived from proven H-class technology, combines a series of new but already tested technologies. The result: A technology carrier to the next level with a combined cycle efficiency beyond 64% and a clear midterm goal of 65%. The HL-class consists of two engines: SGT5-9000HL and SGT6-9000HL.
