Heating with Purpose: WarmteStad’s Inclusive Energy Transition WarmteStad, Groningen’s publicly owned heat company, is driving one of the Netherlands’ most ambitious energy transitions. Founded in 2014, it is operating and continuously expanding its future-proof, 4th-generation district heating network to replace natural gas in 27,000 homes by 2035. This public-led initiative ensures affordable, clean heat for all, offering one of the lowest heating prices in the country and prioritizing neighborhoods with high energy costs. The network is powered by a resilient mix of sustainable sources: waste heat from data centers, one of the world’s largest solar thermal parks, and a seasonal underground heat storage facility that captures summer heat for winter use. Already, 60% of the heat is sustainably produced, with a clear roadmap to reach 100% by 2035. A real-time Digital Twin developed with Gradyent optimizes the full heating system, to enable maximal efficiency and optimal scheduling in relation to volatile electricity markets. WarmteStad’s rollout strategy focuses on older, gas-dependent neighborhoods, aligning with broader urban upgrades like green infrastructure, climate-resilient streets, and improved public spaces. By combining technical innovation, public ownership, and strong community engagement, WarmteStad is not just replacing fossil fuels—it is building a smarter, fairer, and more sustainable urban energy system that puts people and planet first.
