Future Heat Leiden is an open tender for the construction and integration of new sustainable heat sources into the existing district heating network of Leiden. The project focuses on making the heat demand in the region more sustainable and future-proof. The base heat is supplied via a sustainable residual heat source, supplemented by peak and back-up installations to absorb peaks and compensate for outages. A transport capacity of 40 MWth has already been secured with Warmtelinq (Gasunie) for the transport of residual heat from the Port of Rotterdam. The assignment includes design, construction, installation, testing, and delivery of the heat sources and the necessary connections to the district heating network. The focus lies on reliability, energy efficiency, and integration with existing infrastructure.

Future Heat Leiden is a project to make the district heating supply in the Leiden region more sustainable and future-proof. To this end, new heat sources are being developed that will feed the existing district heating network. In principle, a district heating network is based on a sustainable residual heat source supplemented by peak and back-up installations to absorb peaks in heat demand and to be deployed in the event of failure of one of the other sources. For the base load, a heat transport agreement has been signed with Warmtelinq (part of Gasunie) for a transport capacity of 40 MWth fo
