This poster reports the findings of a workshop on AI in the Energy System held in April 2026 in Paris and organised jointly by IEA Wind Task 51 and 63.

Electric grid systems that want to operate with a high penetration of weather-driven renewable generation and other weather-related components need an interdisciplinary forecasting approach in order to optimize the system economics and reliability. Therefore, while anchored in IEA Wind, Task 51 ‘Forecasting for the Weather Driven Energy System’ activities maximize forecasting performance and value and assume a much wider scope. The tasks activities also encompass PV, hydro, biomass, hydrogen, storage and other IEA Technology Collaboration Programmes (TCPs) as well as collaboration with IEC on standardisation. Task 63 has a long history of dealing with large-scale integration of variable renewables into the grids.

IEA Wind Task 51 focuses on facilitating communication and collaborations among international research groups engaged in the improvement of the accuracy and applicability of forecast models and their utility for the stakeholders in the wind industry, in the power sector and in the energy system. Usually, with one public workshop per year, free of charge to attend for all, and later available on the IEA Wind Forecasting YouTube channel.

The most recent activity of Task 51 was a workshop on AI in the Energy System, co-organised with Task 63 Large-Scale Integration. Topics ranged from AI Weather Prediction and AI assisted downscaling of weather products to AI uses in power system management, privacy preserving data sharing through federated learning and opportunities for collaboration.

Additionally, Task 51 develops industry guidelines and recommendations such as the IEA Recommended Practice on Forecast Solution Selection and related software for forecast evaluation, as well as jointly develops the first international standard for forecast evaluation of renewable energy in cooperation with the IEC workgroup 2 under the subcommittee 8A on Grid integration of Renewables (IEC SC8A WG2).
