Every substation, battery energy storage system, wind farm and solar park depends on one critical moment: the connection to the high-voltage grid. These connections demand specialist expertise, precision and absolute confidence in the quality of every termination, joint and test.

Reynard supports utilities, developers, EPC contractors and industrial clients with specialist high-voltage connection services across the Netherlands. Drawing on more than a decade of experience in offshore wind, we bring the same quality standards to complex onshore energy projects.
