The Universitat Politècnica de Catalunya (UPC), coordinator of the STOR-HY project, has published a new scientific article that contributes to advances in condition monitoring of hydropower systems. Published in the Journal of Energy Storage, the paper explores innovative approaches to analysing the dynamic behaviour of pump-turbine units, focusing on improving the reliability and maintenance strategies of pumped storage hydropower.

From research to real-world application
As hydropower systems face increasing operational demands due to the integration of renewable energy, advanced monitoring techniques are becoming essential. Digitalisation and data-driven approaches are key enablers for improving diagnostics, predictive maintenance, and overall plant performance. Against this backdrop, the UPC-led research investigates how operational natural frequencies can be leveraged to gain a better understanding of the structural and mechanical condition of hydropower components. One key finding is that “Operational natural frequencies can serve as health indicators for advanced condition monitoring”.
A foundation for STOR-HY technologies
This insight is particularly relevant for STOR-HY. The ability to track natural frequencies during operation opens new pathways for:
- Early detection of wear and structural degradation;
- Improved diagnostics under real operating conditions; and
- More accurate predictive maintenance strategies.
These findings directly inform the development of STOR-HY’s advanced monitoring solutions, which are designed to detect failure mechanisms at an early stage and optimise maintenance planning in pumped storage plants. Based on this research, STOR-HY will further develop technologies that integrate these indicators into real-time monitoring systems and digital tools. This will contribute to the operation of hydropower becoming more reliable and cost-effective.
Supporting the future of flexible hydropower
By linking fundamental research with applied innovation, this publication reinforces STOR-HY’s mission to reduce operational and maintenance costs, extend the lifetime of hydropower assets, and enhance the flexibility and resilience of Europe’s energy system. As the energy transition accelerates, such advances will be crucial in ensuring that pumped storage hydropower remains a cornerstone of a stable and sustainable electricity grid.
