The forecasting for renewable energy community has been active since the first wind energy projects have begun on Denmark in the 1990'ies. More than 30 years later, there are still no standards on forecasting model input and output, or on evaluation of renewables generation forecasts. At the end of 2022, the IEA Wind Task 51 "Forecasting for the weather-driven energy system" has launched its first Recommended Practice on the Implementation of Renewable Energy Forecasting Solutions, an industry guideline on forecast solution selection, forecast evaluation and collection and quality control of forecast input and verification data and instrumentation requirements.

Since then, the IEC Subcommittee 8A on Grid Integration of Renewables Workgroup 2 Renewable Energy Forecasting, has suggested to establish a standard on evaluation of renewable energy power forecasting, including data preparation, statistics of indicators, evaluation of results and reporting.

The standard shall provide a common understanding of the handling and quality of input data to forecasting of renewable energy as well as how data needs to be prepared and used in evaluation of renewable energy generation forecasts. It aims to close a gap in the understanding of forecasting processes on an international level that enables fair competion on forecasting methods and solutions and access to international markets. Both renewable energy power forecasting service providers and users will benefit from a common understanding of methods of evaluating forecasting for specific tasks and areas and enable transparent comparability of solutions.

The two work groups have joined forces on the standard development and will present the main features of the first working draft of the standard and discuss with stakeholders, whether the chosen approaches support forecasting service providers, users and research institutions on selecting, verifying and improving existing renewable energy forecasting techniques and it's input data quality control.

An inspirational talk will be used as start-up into an interactive session, where the general acceptance, the c

hallenges and the prospects for the benefits of such a standard will be the tpoic of questions to the audience and the p

anelists in the following Q&A part.
