The DeCarbCH case study in Wallisellen reached a milestone and entered the planning phase in 2026. This phase defines supply areas in greater detail, refines the cost estimates and the supply concept named SaisonLink. The DeCarbCH partner OST SPF continues to support die werke versorgung wallisellen ag and the planning team at Gruner AG. Starting in 2028, a staged rollout and construction of the network are planned. By 2035, Wallisellen will invest CHF 100-150 million in the implementation of this heating and cooling network.
