Qirion

What Qirion does

Qirion B.V. is the Dutch high-voltage infrastructure specialist and a wholly-owned subsidiary of Alliander, the Dutch regulated network company. Headquartered in Duiven with regional offices in Amsterdam and Leeuwarden, Qirion designs, builds and maintains the Netherlands' high-voltage grid — including distribution stations (verdeelstations), overhead power lines and high-voltage cables — for regulated grid operators (TenneT, Liander, Stedin), railway infrastructure (ProRail), energy producers (Vattenfall wind farms) and industrial free-market clients. The business operates three fixed assets that are reportedly unique in the Dutch market: high-voltage testing laboratories in Amsterdam and Duiven capable of testing up to 380 kV, a mobile high-voltage lab, and an independent oil laboratory (operational since the late 1980s) performing dissolved gas analysis and physico-chemical testing of transformer and insulation oils. The company maintains roughly 600 transformers, performs around 8 revisions per year, and targets a 15+ year lifespan extension per revision.

Qirion's technology stack centers on a proprietary Modular Construction (Modulair Bouwen) methodology — a standardized set of policies, standards and work instructions that integrates primary, secondary and construction components into reusable building blocks and is reported to compress substation build timelines from ~7 years to 3–4 years. Drone-based inspection (specialized ~11 kg drones with professional cameras and infrared sensors) is used to inspect HV masts and lines without taking them out of service, supported by an AI-based automatic defect detection program under development. The company also deploys an in-house Autonomous Station Regulation (ASR) system that couples multiple generation installations and self-regulates during power peaks. Approximately 200 modular substations are described as planned over the coming years; a pipeline of mega-projects including the Lelystad Larserringweg station (described as Qirion's largest project in its history) and the 7-hectare Zuidplaspolder station underpin forward volume.

The revenue model is professional-services driven: enterprise field sales to grid operators through frame agreements and tenders; long-term Service Agreements (Dienstverlenings Overeenkomst / DVO) for recurring maintenance; project-based construction contracts; and project-by-project quotes in the free market for diagnostics, testing, oil analysis and failure investigation. Pricing is not publicly disclosed. Go-to-market is sales-led and enterprise field-sales driven, with execution delivered via in-house multidisciplinary teams supplemented by contractor partners (VolkerWessels Energy, Friso Bouwgroep, Jorritsma Bouw) and suppliers (TKF, NKT). Operates exclusively within the Netherlands with no disclosed international expansion. In July 2023, Qirion spun off its Qirion Energy Consulting subsidiary into the independent energy consultancy Duurzaam Energie Perspectief (DEP) to sharpen focus on the regulated grid-construction and free-market HV services core.

Core offering

Qirion designs, builds, and maintains the Dutch high-voltage grid for both regulated grid operators (Liander, TenneT, Stedin) and free-market clients (industrial companies, energy producers, ProRail, Vattenfall). Services span the full lifecycle — advisory, engineering and design, construction of distribution stations and high-voltage cables/lines, ongoing maintenance and management via long-term Service Agreements (DVO), and specialized testing, inspection, diagnostics and oil analysis through in-house high-voltage and oil laboratories. Customer work is delivered nationwide through multidisciplinary teams of project managers, engineers and technical specialists.

Product overview

Qirion offers a comprehensive suite of services for the high-voltage energy infrastructure sector. The core offerings include the design, construction, and maintenance of distribution stations (verdeelstations), high-voltage cables and lines (kabels en lijnen), and extensive testing/inspection/diagnostics services through their high-voltage laboratories. Their specialized component services cover power switches, transformers, cables, and high-voltage distributors. An independent oil laboratory provides oil analysis for transformers and insulation components. The subsidiary Duurzaam Energie Perspectief (DEP) provides energy consulting services.
