6B repowering upgrade
The new 6B repowering upgrade can advance performance in both gas turbine and combined-cycle operation—all without sacrificing the unit’s renowned reliability or fuel flexibility.
Benefits
What can upgrading do for you?
- Output increase up to 25% (combined-cycle operation)
- Efficiency improvement up to 5 points (simple and combined-cycle operation)
- Turndown as low as 40%
- NOx reduction as low as 15 ppm
- Fits into the existing 6B footprint
How we get you there
By injecting a range of advanced technologies from GE’s F- and H-Class gas turbine fleets, the 6B repowering upgrade transforms the 6B unit into a GE 6F.01 gas turbine.
The upgrade consists of a full “flange-to-flange” upgrade of all major components including the combustion system, hot gas path, and compressor. Additionally, it incorporates a hot end drive with a new exhaust frame and radial diffuser—a design scaled from the 6F.01 new unit.
We can apply this upgrade to any 6B unit, including machines that operate in a wide range of applications including:
- District heating
- Petrochemical
- Oil & Gas
- Utility for electricity generation

Project details
In an industry characterized by constant change and technological advances, an industrial chemical facility in Asia needed to find a way to improve production levels. To increase efficiency and output while reducing emissions, GE’s new 6B repowering technology will be utilized on three 6B units. The output increase of 25% is expected to help the customer accelerate the rate of chemical production and could lead to significant fuel savings.
