Turbine and generator workshops

Fortum eNext has two dedicated workshops in Scandinavia, ready to support turbine generator owners.

Naantali Workshop full scope of maintenance sercvices

Full-scope turbine and generator maintenance services from our workshops

The workshop in Naantali, Finland, is designed for full-scope turbine maintenance services, and is also equipped with servomotor testing and service facilities. Logistically, the workshop is in an excellent location near Naantali harbour by the Baltic Sea and close to the main road network.

Generators have been produced in Västerås, Sweden, for more than 130 years. This experience, know-how and commitment now live on in Fortum eNext’s workshop, designed for full-scope generator maintenance services. The workshop is fully equipped to repair and rewind both rotors and stators. Next to the workshop facilities, Fortum eNext also operates the only independent high-speed rotor balancing facility in the Nordic countries, expanding the service capabilities even further.

Reverse engineering

Reverse engineering refers to the ability to make a copy of an original part by taking it apart and investigating how it works. By using reverse engineering, we ensure fast access to the necessary spare parts through modelling and in-house manufacturing. 


Re-engineering refers to the ability to not only copy, but also improve a component. This requires extensive engineering know-how and know-why, and in combination with fleet experience is a powerful tool for improving generator reliability.

Extensive engineering capabilities

No matter whether your equipment maintenance requires reverse engineering or re-engineering, we have the competence to help you. Thanks to our extensive experience and expertise in turbines and generators, we can serve our customers using both methodologies depending on the need.
