From 2000W to net-zero : the evolving frame conditions for thermal grid development in the City of Zurich

As cities and municipalities in Switzerland commit to net-zero greenhouse gas by the middle of the century or earlier, aligning local energy policy, planning, and business models becomes imperative. This report examines Zurich's measures towards achieving its 2040 net-zero goal, with a focus on thermal grid planning, operation, and governance. Structured according to WP2's analysis framework, the report examines six dimensions: local and environmental factors, public value dimensions, governance, infrastructure status, business models, and supporting resources. Drawing from various sources including municipal bills, policy documents, media reports, and research findings, the report aims to document Zurich's accelerated transition to assist other municipalities facing similar challenges. Zurich's unique political landscape and resources make it an exemplary case, so that documenting and disseminating its policies helps other municipalities to manage their net-zero transition. Additionally, the report serves as a knowledge hub for researchers, aiding in project proposal development by identifying current city challenges and needs. The city's strategy involves integrating various energy potentials and implementing regulatory, organizational, and financial measures to accelerate decision-making and implementation. Notable changes include continuous strategic energy planning, a new net-zero monitoring instrument, and governance adjustments for fast decision-making. The report identifies successes, such as high demand for financial support and progressing grid expansion. However, challenges like infrastructure planning complexities and limited influence on building owners remain. Zurich serves as both an extreme and critical case, offering insights into effective policies, organizational measures, and technical solutions for transitioning to net-zero. Learning opportunities include studying customer reactions to tariff incentives, the success of renewable products, and the impact on the local business ecosystem.
