Warmtebedrijf Rotterdam and Nuon have signed a new agreement aimed at supplying residual heat from the port of Rotterdam to the greater Leiden area in the Netherlands.

Rotterdam’s port area generates a large volume of residual heat, a lot of which is currently ‘thrown away’. The district heating project uses this residual heat as a replacement for gas – resulting in a substantial reduction of greenhouse gas emissions.

The project also known by the name Warmtelevering Leidse Regio (WLR) ties in with the objectives set out in the policy outlook Leidse Warmtevisie and the Holland Rijnland regional energy covenant.

That agreement is assisting Leiden in transitioning away from gas, with a reliable and sustainable heat supply for some 13,000 households and 200 companies. Parties are presently examining which options there are to expand the programme into Southwest Leiden and the Station District.

In early 2017, the Province of South Holland, the Port of Rotterdam Authority, Gasunie, Eneco and Warmtebedrijf Rotterdam joined strengths in the South Holland Heat Alliance (Warmtealliantie Zuid-Holland). The alliance is set to launch a regional heat distribution system and has identified various options to connect some 500,000 households and a share of the local greenhouses to a regional heat distribution system
