What does the expansion of data centers mean for Switzerland? On behalf of the Swiss Energy Foundation, INFRAS is investigating the local impact of data centers on the energy system. The aim is to identify possible solutions for a sustainable expansion of data centers.
The global expansion of data centers is accelerating rapidly, driven by the growing demand for cloud services and AI applications. Data centers are also being built in Switzerland, particularly in the Zurich area.
Data centers generate spatially concentrated loads that can potentially affect grid stability, infrastructure and local electricity prices. They also have other local impacts, such as water use, transportation, waste heat recovery, and value creation.
Electricity consumption is expected to increase significantly by 2030.
Against this backdrop, the Swiss Energy Foundation (SES) commissioned INFRAS and the Roegen Center for Sustainability to conduct a comprehensive analysis of the local impacts and, where necessary, to identify possible solutions.
The study provides an overview of the current data center stock in Switzerland and possible developments in the coming years. Initial analysis suggests that electricity consumption is likely to increase significantly by 2030.
Local impacts reveal complex systemic effects
The study examines how different types of data centers can affect the energy system, for example by generating different load profiles and causing short-term load peaks. This leads to potential additional requirements for grid expansion, flexibility and tariff structures. In addition, other local impacts, such as strain on infrastructure or water consumption, are qualitatively assessed.
Proposed solutions combine efficiency, regulation and sufficiency
The study will develop and examine a range of potential solutions. These approaches will be evaluated for effectiveness and feasibility in consultation with practitioners.
The project was launched in spring 2026. The full results will be documented in a detailed final report in early 2027 and presented at a public event organized by SES.
