What NetVerder does

NetVerder B.V. is a Dutch sustainable energy infrastructure company and wholly-owned subsidiary of Stedin Groep, headquartered in Delft, Netherlands. The company develops, constructs, and operates smart, sustainable energy networks for collective heat (warmtenetten), industrial steam (stoomnetwerken), and sustainable gases. Its core technology portfolio includes district heating networks powered by geothermal energy (aardwarmte), seasonal thermal energy storage systems (WKO/Warmte Koude Opslag) combined with surface water systems, low-temperature heat networks, and industrial steam exchange networks. Notable technical components include the Botlek Steam Network connecting steam producers (AVR, Cabot) with industrial consumers (Lanxess, LyondellBasell, Huntsman), the geothermal source at TU Delft Campus delivering heat at approximately 75°C, and an open innovation heat network at The Green Village field lab for testing new heat technologies. The company also operates the Open Innovatie WarmteNet on The Green Village as a regulation-light testing environment for heat innovation.

NetVerder generates revenue through three primary streams: (1) regulated cost-plus heat tariffs for residential and commercial customers (subscription/recurring), with maximum tariffs set annually by the Dutch government under the Wet collectieve warmte; (2) industrial steam network capacity and usage fees from B2B contracts with chemical companies; and (3) WKO system management fees through its subsidiary DNWG Warmte. The company employs an enterprise field sales GTM motion, acquiring customers through long-term partnerships with municipalities (Delft, The Hague, Rotterdam, Utrecht, Vlissingen, Vlaardingen, Terneuzen, Waddinxveen), social housing corporations (DUWO, Vidomes, Stedelink, Woonbron), and industrial companies, with multi-year development cycles aligned to the Dutch Warmtewet (Collective Heat Act) regulatory framework.

As of 2025, NetVerder manages 3 active heat networks and is developing 5+ additional projects across the Netherlands, with total pipeline targets of approximately 75,000+ residential connections (Delft 15,000, The Hague 24,000, Oostland 45,000) plus 1,500 hectares of greenhouse horticulture. The company is structured as a public-heat entity prioritizing continuity over profit maximization, backed by Stedin Groep's capital, strategic oversight, and shared services. The company is ISO 9001:2015 certified and achieved SCL (Safety Culture Ladder) Level 3 in 2024.

Revenue model

1. District Heating Network Management & Exploitation: NetVerder develops, constructs, and operates heat networks, serving as the future network manager responsible for all aspects of the heating network lifecycle. Revenue is generated through network exploitation fees charged to connected customers (residential, commercial, industrial). Pricing is cost-plus based, with regulated maximum heat tariffs set by the government.
2. Steam Network Infrastructure: NetVerder owns the steam network infrastructure in the Rotterdam-Botlek industrial area, connecting steam producers (e.g., AVR, Cabot) with steam consumers (e.g., Lanxess, LyondellBasell, Huntsman). Revenue comes from infrastructure usage fees and network capacity charges.
3. WKO System Management: Management of WKO (Warmte Koude Opslag / Seasonal Thermal Energy Storage) systems for sustainable heating and cooling, currently in exploitation in Goes (Ouverture neighborhood, managed since 2022). Revenue generated from heat and cold delivery to connected buildings.

Broad incumbents

• Vattenfall Warmte: Large European utility operating extensive district heating networks in the Netherlands (including Amsterdam) and other countries. Comparable as a much larger established district heating operator with overlapping customer base in the Dutch residential heat market.
• Fortum: Nordic energy company with major district heating operations, including recent acquisition of German municipal heat networks. Comparable as a broad incumbent in collective residential and industrial heating with overlapping renewable and residual-heat strategies.
• ENGIE Solutions: Global energy and district heating operator with European heat network portfolios and industrial energy services. Comparable as a broad incumbent offering similar collective heat and industrial steam/heat services across European markets, though with much larger scale.
• Eneco: Major Dutch energy company with significant district heating operations (e.g., in Rotterdam and Utrecht) and heat pump businesses. Comparable as a broad incumbent competing for municipal heat-network designations and residential heating customers across the Netherlands.

Others

• Copenhagen Infrastructure Partners (CIP): Infrastructure fund manager with thermal-energy and district-heating investments across Northern Europe. Comparable as a capital partner and co-developer in the same European heat-network infrastructure asset class rather than as a direct operating competitor.

Regional players

• Statkraft Varme: Norwegian district heating subsidiary of Statkraft focused on developing low-temperature heat networks using geothermal, sea-water, and waste-heat sources. Comparable as a regional Nordic operator using similar heat-source strategies (geothermal, residual heat) for residential networks.
• MVV Energie: German municipal utility operating extensive district heating networks in Mannheim and other German cities. Comparable as a regional public-utility-style operator developing low-temperature and geothermal-based heat networks, though primarily serving Germany rather than the Netherlands.

Direct peers

• Firan (Alliander): Heat network subsidiary of Dutch grid operator Alliander, focused on developing collective heat solutions for municipalities. Directly comparable as the third Dutch grid-operator-owned heat infrastructure business pursuing the same aardgasvrij opportunity.
• HVC: Dutch waste and energy company operating district heating networks across multiple municipalities. Comparable as a Dutch public-utility-style operator combining residual heat, biomass, and waste heat sources into collective heating networks for residential and commercial customers.
• Enpuls Warmte Infra (Enexis Groep): Subsidiary of Dutch grid operator Enexis Groep developing and operating district heating networks across the Netherlands. Direct structural peer as the other major regional grid operator-owned heat network developer, explicitly co-developing the Open Innovatie WarmteNet with NetVerder.
