A century of innovation

Keeping generators up and running

We’ve been installing and maintaining power generators since the 19th century and have placed more than 14,000 medium and large generators into service. Our global network of service engineers and repair shops have performed hundreds of rotor field and stator repairs and responded to thousands of generator outages. As a result, GE Vernova is uniquely positioned to enable you to extend the life and reliability of your generator through industry-leading short-cycle large generator repairs and maintenance.

Types of turbine generator repairs

Whether it’s on-site or in our workshop, you can trust our commitment to quality generator repairs.

On-site power plant generator repairs

By leveraging decades of engineering and industrial generator repair experience, we’ve developed a wide range of on-site repair solutions to increase the reliability of your generator asset.

  • APLETEC*: Stator water box leakage repair
    Seal leaking water boxes by exposed coating with only disconnecting the hydraulic hoses (no bar removal)
  • Metal spraying: On-site generator rotor repair
    Rotor seal oil journals repair: Low coefficient of friction of the sprayed metal reducing rubbing effects between rotor shaft and oil seal rings
  • On-site stator core repair
    Prosthesis: Alternative technology to partial core ends restacking
  • Stator onsite re-wedging
    Retightening or replacement of the wedging system
  • Stator dovetail wedge shimming 
    In-situ wedge tightening process that nearly eliminates the material lead times and cuts the overall cycle time

Fast support for Alliant Energy’s OEM outage

14,000+

GE Vernova generators are in service worldwide

Hundreds

of rotor and stator repairs performed for customers

GE Vernova won the bid to manage Riverside Power Plant’s outage on Unit 1 with a leading technical approach, strategic inventory management, and robust supply chain standards. The GE Vernova team faced difficult obstacles presented by the complex horizontal core restack repair, as well as the first application of the stator flexpack. They overcame these hurdles on the strength of the team’s technical strategy, supply chain management, and efficient, dedicated teamwork. Alliant’s outage concluded with zero safety or quality incidents—and before the project deadline.
