The scenarios provide a detailed overview of possible European energy futures up to 2040. For the first time in 2018, ENTSO-E and ENTSOG, the European networks of transmission system operators for electricity and gas, have pooled their efforts and expertise to provide a joint set of scenarios. They will be used by ENTSOs and other organisations to analyse the future of the European energy system, starting with the ten-year network development plans (TYNDPs) and mid-term adequacy forecast (MAF).
