AIB has published the Residual Mixes and European Attribute Mix of 2023. These figures represent the part of electricity supply in Europe that is not tracked with guarantees of origin and therefore guaranteeing the accuracy and reliability of the GO system. The calculation was carried out by Grexel Systems Ltd on behalf of AIB. The 2023 calculation marks the fifth consecutive year in which the AIB Residual Mix calculation has been carried out according to the Shifted Issuing Based Methodology. Using this methodology, results continue to be consistent year-on-year.
