From 8 to 10 December 2025, the EUMETNET - E-TREND Joint Workshop on Postprocessing, Forecasting and Nowcasting for Renewable Energy, also known as RenEUCast25, was held at Vrije Universiteit Brussel (VUB). RenEUCast25 was meant as a dedicated event for the exchange of knowledge focused on effective forecasting and postprocessing for the renewable energy sector, and to promote a better understanding of how end users integrate forecasts and current developments in their decision-making processes.
