Comparison of Feed-in Data for European Energy System Modelling

Abstract

<p>The world  is shifting towards renewable energy to tackle the imminent threat of climate change.</p><p>To plan the decarbonisation, large-scale energy system models are utilized, which require accurate data on renewable generation to develop their full potential. Using different data can lead to conflicting results and policy advice.</p><p>In this work, we compare several reanalysis-based datasets, which provide generation data for wind and solar PV on the country level,to study the transition towards a highly renewable European power system. Significant differences between these datasets are found, resulting in remarkable cost differences and the potential misallocation of large investments.</p><p>The findings, which will be presented, indicate that much more attention must be paid to the large uncertainties of the input data in two ways: Understanding the differences and developing appropriate methods to deal with them.</p>
