10 December 2019 - A major new energy innovation project to demonstrate how smart hydropower technologies can deliver a low-carbon, reliable and resilient power system was launched today.
The €18 million initiative was announced by the European Commission and a consortium of 19 partners at the United Nations climate change conference (COP25) in Madrid, Spain. It will show how innovative and flexible hydropower systems can help countries across the world meet their renewable energy targets.


The XFLEX HYDRO (Hydropower Extending Power System Flexibility) project is a four-year initiative by leading utilities, equipment manufacturers, universities, research centres and consultancies. It will demonstrate how modern hydropower plants can provide the vital power grid services required by variable renewables such as wind and solar power.

The launch comes after a major UN Emissions Gap Report looking at ways to reduce global carbon emissions said that greater power system flexibility was “key” to integrating larger shares of variable renewable energy into the power supply. 

The XFLEX HYDRO technologies to be tested are enhanced variable- and fixed-speed turbine systems, smart controls and a battery-turbine hybrid, each of which will be demonstrated at hydropower plant sites across Europe. 

The project will conclude in 2023 by delivering a roadmap to increase adoption of the technologies across the hydropower fleet, with policy and market recommendations for governments, regulators and industry.

The initiative has received funding from the European Union’s Horizon 2020 research and innovation programme. It aims to help the EU achieve a target of achieving 32% of energy from renewable sources by 2030.
