The SURE project 

The Sustainable and Resilient Energy for Switzerland (SURE) project, funded under the Swiss Federal Office of Energy’s SWEET programme and coordinated by the Paul Scherrer Institute, explores how to reconcile resilience and sustainability with Switzerland’s energytransition goals. Bringing together ten research partners and a broad stakeholder forum, the sixyear project (2021–2027) aims to provide decisionmakers with strategies to design an energy system that is robust against disruptions, environmentally sustainable, and socially acceptable.

SURE develops a novel, interdisciplinary modelling and data framework that integrates environmental, economic, securityofsupply, and socialwellbeing considerations. The framework links multiple sectoral and macroeconomic models, including the Swiss TIMES Energy System Model (STEM), with complementary tools for buildings, spatial electricity dispatch, and grid operations. This integrated approach enables a comprehensive assessment of transition pathways, capturing both longterm structural change and shortterm resilience under potential disruptive events.

Stakeholder engagement is central to the project, with energysector representatives contributing to scenario design, indicator selection, and pathway evaluation. The results will inform a multiobjective decisionsupport tool to help policymakers and industry identify robust, sustainable transition strategies that align with Switzerland’s Energy Strategy 2050 and climateneutrality target.
