The IEA Wind TCP Task 51 Austria - Stakeholder interaction and priorities for forecasts

This work presents key findings from the first Austrian workshop of IEA Wind TCP Task 51 on "Forecasting for the Weather-Driven Energy System", which brought together 120 participants from over 50 organizations. Through structured stakeholder engagement, the workshop revealed critical priorities for advancing renewable energy forecasting in complex terrain.

Results highlight the continued dominance of day-ahead forecasting (56% of respondents), while identifying growing needs in extreme weather prediction (85% concerned) and artificial intelligence integration (rated 4.35/5 in importance). On the other hand, a number of gaps were identified related to the awareness of extremes and uncertainty and the knowledge and implementation status of such forecast tools. The Alpine context presents unique challenges, where complex terrain and cross-border power flows create specific forecasting requirements. Based on stakeholder feedback, two follow-up workshops will be organised focusing on extreme events and integrated forecasting solutions.

This study provides concrete guidance for developing next-generation forecasting systems and demonstrates the value of structured stakeholder engagement in shaping forecasting solutions for the energy transition.
