A recent meeting of energy leaders in Switzerland presented the results of a series of technological upgrades made to hydropower plants across Europe to support the energy transition and secure stability of the power grid.
The upgrades are part of the four-year, €18 million (US$19.6 million) XFLEX HYDRO research and innovation project. The project combined internationally-recognized expertise to study and demonstrate that it is possible to extend the flexibility of existing hydropower plants using advanced software solutions and modest technological upgrades. XFLEX HYDRO, scheduled to run until early 2024, marks a step change in our understanding of the benefits hydropower offers and our ability to provide much-needed stability services to the power grid, according to the International Hydropower Association.
Serving as the backbone of many power systems, hydropower has generated renewed interest in recent years as the global drive for renewable energy has gathered pace. The mainly digital upgrades of XFLEX HYDRO represent a shift from traditional, hardware-focused modernization initiatives. By enhancing the ability of hydropower plants to provide not only baseline and peak power but also crucial grid stability services, the project has uncovered new potential value.
“The European Union’s vision for 2050 hinges on renewable energy sources constituting over 80% of its energy, a significant leap from 37.5% in 2020. This means that sustainable hydropower will continue to play a central role in Europe’s clean energy transition in the coming years. The extent to which the technology will contribute to this target will depend on our ability to take full advantage of its benefits,” said Eddie Rich, chief executive officer of IHA. “We are proud to work alongside expert partners from across Europe on the XFLEX HYDRO journey and look forward to more collaboration in the coming years. The decarbonization of European electricity will inevitably involve significant clean, green, modern and affordable hydropower. XFLEX HYDRO lights the path.”
The event explored a series of upgrades, including hydropower turbine and battery hybrid, variable speed turbines, and new and optimized operational modes. Participants discussed how to prepare for the energy transition, how to manage the rise of intermittent renewable energy and how to get the most out of hydropower assets.
“Alpiq already has flexible assets like Nant de Drance and is seeking to extend the flexibility of its portfolio with state-of-the-art technologies to contribute to an improved security of supply. The XFLEX HYDRO project has enabled us to progress with this while strengthening our strategic partnerships with universities and schools,” said Amédée Murisier, head hydropower at Alpiq.
