The contract continues the decades-long, trusting collaboration with Ennskraftwerke AG and underscores Bilfinger’s expertise in the energy sector
The goal is to ensure efficiency and plant availability for reliable, sustainable electricity generation in Austria
Mannheim, Germany / Steyr, Austria. International industrial services provider Bilfinger has been awarded a contract by Ennskraftwerke AG for the overhaul of the two generator units at the Garsten - St. Ulrich power plant in Upper Austria. The scope of work includes the prefabrication, refurbishment, and installation of rotating and static equipment, which is scheduled for completion by March 2028. These services will ensure long-term reliability and efficiency of power generation.
Ennskraftwerke AG is a long-established Austrian energy company that operates twelve hydroelectric power plants on the Enns River and two on the Steyr River, making a significant contribution to Austria’s sustainable electricity supply. The power plant in the municipalities of St. Ulrich and Garsten generates an average of 157 gigawatt-hours of sustainable electricity annually, covering the annual needs of approximately 40,000 households in the region.
The overhaul of both generators includes the replacement of the two stators, all rotor poles, and the fans, which are being manufactured by Bilfinger prior to the start of these works. The remaining generator components will be thoroughly inspected and refurbished by Bilfinger before being put back into service. Bilfinger covers all aspects of the overhaul – from prefabrication to disassembly of the generators and to refurbishment, installation, and commissioning.
The latest contract continues the trusting collaboration that has existed for decades at several of these hydroelectric power plants: “Bilfinger has proven to be a reliable partner for us, who meets the highest quality standards and adheres to demanding schedules,” says Michaela Steinparz, Spokesperson for Ennskraftwerke AG. “We are pleased to once again have an experienced team by our side, who will support us in further strengthening our position as a key energy supplier in the region.”
Thierry Burki, Segment President Central Europe, says: “The fact that we were able to further expand our collaboration with Ennskraftwerke is a testament to the expertise of our teams. This contract is an outstanding example of Bilfinger’s experience in the field of rotating equipment – particularly for critical infrastructure. We are pleased to contribute to a sustainable energy supply in Austria together with our customer.”
Hydroelectric generators are among the longest-lasting components in power generation, designed for a service life of 50 to 100 years. Bilfinger’s services ensure that this asset life is achieved while meeting the highest levels of reliability and efficiency.
