Maintaining the high-voltage systems that transmit offshore wind power safely and efficiently.
OVERVIEW
Offshore Wind High Voltage (HV) Technicians are responsible for maintaining and operating the high-voltage electrical systems that connect offshore wind turbines, substations, and export cables to the electricity grid.
These systems carry electricity generated by turbines at very high voltages across offshore networks and back to shore. HV technicians ensure these systems operate safely, reliably, and efficiently by inspecting, testing, and maintaining critical electrical equipment.
This is a highly specialised technical role suited to individuals with experience in electrical engineering, power systems, or industrial electrical maintenance, particularly those who enjoy hands-on work in offshore environments.
