Construction is under way on an auxiliary heat plant at Het Groene Veld in Amsterdam-Noord, on a green area by the former water-treatment plant near the ADM community and Elzenhagen. Westpoort Warmte, a partnership between Vattenfall and the Municipality of Amsterdam, is building the facility, which is due to enter service in autumn 2027.

The plant is intended to provide additional heat to about 10,000 households in Noord during very cold weather or if AEB Amsterdam's heat supply has problems, and is expected to operate only intermittently. The steel structure and internal cladding have been installed, with an exterior facade still to follow. Residents and members of the ADM community had sought to prevent the project, but the construction is proceeding; Vattenfall's project manager said relations with neighbouring residents are now good.
