Description
Amsterdam imposed a moratorium on new data centre 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 resolving the underlying commercial question: no party was willing to fund the collection network and heat pumps, because free heat generates no revenue stream against which that capital investment can be financed. Multiple sites in the region installed pipework and remain 'heat recovery ready' with no heat flowing. The German Energy Efficiency Act parallel is directly instructive: its mandate for an energy reuse factor rising from 10% to 20% was relaxed in the April 2026 draft amendment, which waives the requirement where no feasible network exists within 5 km, leaving only an obligation to offer the heat — the strongest such mandate was softened within three years explicitly to cut compliance costs. The distinguishing variable between this failure and functioning markets in Odense and Stockholm is not engineering; it is whether the delivered megawatt-hour appears as an asset on a buyer's balance sheet.
