Warmte netwerk Westland

What Warmte netwerk Westland does

Warmte Netwerk Westland (WNW) is a Dutch non-profit limited partnership (C.V.) co-founded by HVC and Capturam, operating as the regulated network manager (netbeheerder) for a regional geothermal heat network in the Westland and Midden-Delfland regions of South Holland. The company does not own the geothermal wells themselves; instead, it connects multiple HVC-operated geothermal sources (Trias Westland, Aardwarmte Maasdijk, Aardwarmte Polanen, and forthcoming sites such as Vogelaer and Wippolderlaan) to greenhouse horticulture businesses, and ultimately to residential areas and business parks, through an underground insulated pipeline network delivering heat at approximately 90°C from doublet wells at ~2.3 km depth. As of early 2026, the operational network spans 16+ km of pipeline in Maasdijk (planned to ~33 km) with first heat delivery from Polanen commencing in February 2026, giving a combined capacity of ~72.5 MWth.

WNW's products comprise three layers: the physical heat network infrastructure (Warmtenetwerk), the Handelsplatform online trading market which uses merit-order pricing to enable geothermal sources and greenhouse businesses to trade heat daily, and the heat delivery stations (afleverstations) installed at customer premises in capacities from 500 kW to 4,500 kW (supplied by Que-tech). The commercial model combines usage-based heat transport fees with a transaction-fee layer on the trading platform; only pricing signals are publicly observed, with first-month clearing prices averaging €17/MWh on 900 MWh traded across 24 participants. Customers are acquired primarily through two heat cooperatives (Warmtecoöperatie Maasdijk with ~33 members and Warmtecoöperatie Polanen with ~50 members) that act as group purchasing vehicles, alongside direct contracts with municipalities for residential connections starting in Maasdijk (730 planned households plus a school).

The company is funded through public grants — primarily the Nationaal Groeifonds via the NieuweWarmteNu! consortium and Kas als Energiebron — plus a December 2022 consortium of five banks and insurers. It carries a 7-person organization, has explicitly stated ambitions to reach 500 MW of transport capacity by 2030 (targeting 80% of Westland's greenhouse heat demand and saving 650 million cubic meters of natural gas annually), and is exploring a future connection to Rotterdam port residual heat via WarmtelinQ (intent declaration signed July 2026).

Core offering

Warmte Netwerk Westland operates a regional district heating network that connects geothermal heat sources (doublet wells at approximately 2.3 km depth) to commercial greenhouse horticulture businesses and (planned) residential areas in the Westland region through underground insulated pipelines and customer-site heat delivery stations. As network operator and system administrator, it balances supply and demand across multiple geothermal clusters. The company also operates the Handelsplatform, an online merit-order-based trading platform that enables geothermal producers and greenhouse buyers to trade surplus heat on a daily basis.

Product overview

Warmte Netwerk Westland operates a dual-product system comprising the core Heat Network Infrastructure (Warmtenetwerk) and an online Trading Platform (Handelsplatform). The infrastructure transports geothermal heat through underground pipelines to greenhouse businesses and residential areas, while the trading platform enables real-time heat trading between geothermal sources and approximately 200 greenhouse businesses. Supporting the network are heat delivery stations (afleverstations) installed at customer sites with capacities ranging from 500 kW to 4500 kW.

Scale indicators8 records

Recent moves6 records

Expansion highlights6 records

Regional players

• Hellisheidi Geothermal Power Station (ON Power): Icelandic combined geothermal power and district-heating operator serving the Reykjavik capital region. Comparable as a major geothermal heat-and-power system with district-heating distribution, though located in a very different regulatory and geological environment.
• Stadtwerke München (Münchner Fernwärme): Municipal utility operating one of Europe's largest district-heating networks in Munich, combining geothermal, waste-heat, and CHP sources. Comparable as a publicly backed multi-source district-heating operator, though it serves a different geography (Germany) and operates at much greater scale.

Direct peers

• HVC: JV partner of WnW and the operator/developer of all underlying geothermal wells (Trias Westland, Aardwarmte Maasdijk, Aardwarmte Polanen, 12 wells in Westland). HVC is the closest functional peer, owning the supply side of the same regional heat system WnW operates.
• WarmtelinQ (Gasunie): Gasunie subsidiary building a national backbone for residual-heat transport in the Netherlands, with a planned connection to WnW. Directly comparable as a heat-transport infrastructure operator using similar underground pipeline technology.
• Trias Westland: HVC-operated geothermal project supplying heat into the WnW network from two doublets in the same Westland region. Directly comparable as a geothermal heat producer feeding the same end-customers, even though it sits on the supply side rather than the network-operator side.

Broad incumbents

• Vattenfall Warmte (Netherlands): Vattenfall's Dutch district-heating arm serves major urban areas (e.g., Amsterdam) with sustainable and residual heat. Comparable as a large, established Dutch heat-network operator, although it operates at much greater scale and with different supply sources.
• Ennatuurlijk: Dutch district-heating utility operating multiple heat networks for residential and commercial customers across the Netherlands. Comparable as a regulated heat network operator and customer-facing utility, though it is not geothermal-focused.
• Eneco Warmte: Eneco's district-heating division operates heat networks in several Dutch municipalities (e.g., Rotterdam, Den Haag). Comparable as a multi-region Dutch heat utility, though Eneco's portfolio is broader and not centered on geothermal sources.

Others

• EBN (Energie Beheer Nederland): Dutch state participation company involved as a partner in the NieuweWarmteNu! consortium exploring sustainable heat supply in South Holland. Comparable as an ecosystem participant and co-investor in Dutch geothermal/heat-network development, rather than a direct network operator.

Emerging players

• Aardwarmte Polanen: Geothermal doublet project in the Westland region, owned by HVC, currently feeding ~22.5 MWth into the WnW network. Comparable as a focused geothermal project developer in the same region with a single doublet at ~2.3 km depth.
