Reynard High Voltage Solutions

What Reynard High Voltage Solutions does

Reynard High Voltage Solutions B.V. is a Dutch specialized services provider delivering high-voltage cable jointing, termination, and testing for the energy transition. Founded in 2011 and headquartered in Nieuw-Vennep, Netherlands, the company fields a team of 320+ dedicated high-voltage technicians supported by total headcount in the 501–1,000 range per firmographic data. Core service lines include offshore and onshore HV jointing, resonance and VLF testing up to 72.5 kV AC, full-service Balance of Plant subcontracting, pre-terminated cable products, and recurring consultancy/maintenance. Customers are exclusively enterprise: offshore wind farm developers and operators, onshore grid operators and asset managers, battery energy storage system (BESS) developers and EPCs, and cable manufacturers, with active project references in the Netherlands, the UK (Dogger Bank), Taiwan, China, and the US.

The technology stack combines certified human expertise with proprietary tooling. Reynard operates the DNV-certified Reynard Academy (NEN 3840 curriculum, skills assessments, VR Academy Experience) as an internal talent factory, paired with the Toolbox Suite mobile application (iOS/Android) for digital cable termination records and project transparency, and company-owned Mohaupt VFRTS72 resonance testing systems housed in DNV 2.7-1-certified offshore containers. Certifications underpinning the offering include ISO 9001, ISO 45001, VCU, NEN 4400-1, and Safety Culture Ladder rung 3.

Reynard is a privately held B.V. with no disclosed parent, no external funding rounds, and ownership appearing to be founder/management-led under CEO Jonne Schortinghuis. Revenue mechanics rest on quote-driven project-based professional services and managed services contracts (full-service subcontracting covering engineering, personnel, equipment, logistics, testing, and commissioning), supplemented by one-time product sales of pre-terminated cables and a recurring consultancy/maintenance stream. Pricing is not publicly disclosed; the only explicit figure is a EUR 18,000 HV Jointer training fee, waived at EUR 750 per rotation upon completion of 24 rotations within three years. Go-to-market is direct enterprise sales via RFQs and project bidding, supported by industry event presence (OEEC 2025), content marketing, and a dedicated careers portal for global deployment.
