This report defines the four identified pathways scenarios of the SWEET-SURE project as well as five scenarios representing disruptive events. The development of these scenarios are based on an interdisciplinary and inclusive approach including the project’s research partners and the SURE stakeholder forum. The scenarios are described in detail and corresponding information to quantify the scenarios using energy models is provided. Beyond this, model connections of the comprehensive analytical framework of SURE are sketched, highlighting the major parameters and variables exchanged between the SURE models for the national analysis. As such, this report represents a fundamental document for the application of the analytical framework and the collaboration among the modelling teams in SWEET-SURE.
