Connect the facility's cooling loop to a district heating network under a contract that pays per MWh delivered at a market-referenced price. Stockholm's open market has ~20 suppliers; Odense delivers 215,000 MWh/year to over 12,000 homes using ammonia heat pumps.

A central plant chills water and pipes it underground to many buildings, replacing individual AC units. It rejects waste heat away from street level, cutting energy use per unit of cooling and the anthropogenic heat that feeds the urban heat island.

Amsterdam imposed a moratorium on new data-center development from 2019 to 2021, with heat reuse among the conditions placed on the sector. Operators offered waste heat free of charge. The moratorium was lifted without…

Waste heat from Meta's Odense facility is captured and lifted by ammonia heat pumps from 30–40°C to 70–75°C (the temperature Fjernvarme Fyn's network requires) and delivered into the municipal district heating system. I…

Marina Bay is served by what operators describe as the world's largest underground district cooling system, operational since 2006 and built into a master-planned new downtown. Central chilled-water plants supply connec…
