This research activity focuses on bringing the general SURE framework to the cantonal level and complementing it with a tool aimed at regional policymaker end-users. This case study for canton Ticino fits within the general SURE framework in terms of the main objective of i) using models to describe energy system transition pathways and ii) assessing the sustainability and resilience of the resulting energy system through a Multi-Criteria Decision Analysis (MCDA). As in the SURE framework, the cantonal case study emphasises on an early and continuous engagement of stakeholders that will help frame the challenges and opportunities of the energy system transition scenarios.
