What will Europe's energy system look like in 10 years? The 2030 targets for decarbonising the EU economy have been agreed. The transition is underway. The integration of renewable energy resources and turning the existing power system into a smart grid are among the top goals. The EU-funded ERIGrid 2.0 project will address the challenges of the energy transition by widening and advancing access to European research infrastructure. Serving as a single-entry point for researchers, engineers and practitioners who are active in smart grids and energy systems as well as the integration of renewables, the project will develop a broad spectrum of improved services, methods and tools based on the outcomes of the predecessor projects DERri and ERIGrid. As a pan-European research infrastructure (RI), that integrates 21 first-class laboratories located in 13 European countries, ERIGrid 2.0 offers interested researchers, engineers, and practitioners free-of-charge access to laboratories and associated services along with logistical, technological and scientific support for their own experimental research. This first user workshop provides the opportunity for six selected user groups (out of around 50 realised access projects) to present their results and findings from the laboratory access program.
