Gas generator stator rewinds
GE Vernova offers a comprehensive portfolio of generator stator upgrades, including rewinds and replacement stators for all generator makes, engineered to enhance reliability and improve asset availability.
Protect uptime
Gas generators: The critical role of stator rewinding
Gas turbine generators face unique challenge:
- Higher thermal stress from operating environments
- Insulation degradation and hot spots over time
- More frequent starts, stops, and peak load cycling
- Increased risk of costly unplanned outages if issues go unaddressed
Rewinding your generator stator is one of the most effective strategies to mitigate these risks and extend the life of your equipment.
Latest technology
Extend generator stator life and boost output
Increase your generator’s output by integrating the latest advancements in insulation materials and enhanced end-winding support systems. GE Vernova’s generator stator rewinds and upgrades leverage advanced tooling, high-tech manufacturing, and standardized processes. By combining new materials with proven processes, a stator rewind maximizes both short-term availability and long-term asset value.

Generator stator cycling operation services
Power plant generators were originally engineered for steady base load operation. Today’s industry shift toward cycling operations—frequent starts, peak load conditions, and extended turning gear use—places additional stress on generator stators. GE Vernova offers services designed for these challenges.
- Fast generator stator rewind
- Flex Package
- Replacement generator stator
Our accelerated stator rewind process leverages a streamlined, single-process technology compatible with conventionally cooled generators. Customers benefit from:
- Rapid turnaround and minimized downtime
- Proven technologies applied across OEM and cross-fleet stators
- Seamless integration into major turbine outages
- Up to 15% output improvement (depending on generator type)
GE Vernova’s Flex Package prepares your plant for cycling operation and helps prevent component failure.
Benefits include:
- Longer stator lifetime designed for modern operating conditions
- Up to 5,000 start-stop cycles with legacy copper
- Up to 10,000 cycles with advanced copper
A replacement stator is an ideal solution when outage windows are tight. With GE Vernova, replacement stators can be manufactured in parallel with plant operations, minimizing downtime.
The GE Vernova advantage:
- Proven, reliable stator designs
- Replacement for obsolete, impregnated stators with modern alternatives
- Emergency response options for high availability
