A comprehensive modernization program has been completed at three hydropower facilities operated by Dravske Elektrarne Maribor (DEM), significantly enhancing their operational efficiency and long-term reliability.
The upgrade covered the hydropower plants in Dravograd, Vuzenica, and Mariborski otok, where key secondary systems were fully modernized over a three-year implementation period. Through the introduction of advanced process equipment and digital technologies, the company expects the plants to operate efficiently for at least another 20 years.
A major component of the project was the integration of modern data management systems, enabling real-time operational monitoring and predictive maintenance capabilities. In parallel, improvements were made in cybersecurity, while the lifespan of primary equipment has effectively been extended into the later stages of its operational cycle.
One of the most notable outcomes of the modernization is the deployment of a newly developed digital turbine control system, designed in-house by DEM’s engineering team. This innovation represents an important step toward greater technological independence and improved optimization of hydropower plant performance.
Overall, the project marks a significant milestone in the digital transformation of DEM’s hydropower fleet, strengthening both operational resilience and long-term system sustainability.
