We are currently looking for a Senior Electrical Commissioning Specialist in the framework of the pre-commissioning and commissioning of a large-scale hydrogen production facility in the Netherlands.

The assignment consists in leading the electrical pre-commissioning, energization, functional testing and grid integration activities of a complex industrial power system, from High Voltage and Medium Voltage distribution through to power conversion units and downstream electrical consumers.

The position is site-based in the Netherlands, with occasional business trips within Europe.

On a daily basis, the Senior Electrical Commissioning Specialist will report directly to the Commissioning Manager and coordinate closely with the site, electrical, instrumentation and vendor teams.

• Supervise cold and hot commissioning of HV GIS switchgear and main power transformers, including insulation, timing and protection integrity checks.
  
• Lead the pre-commissioning and energization of MV switchgears, transformers and distribution feeders in order to secure power availability for downstream plant loads.
  
• Commission reactive power compensation systems, including StatCom modules and harmonic filters, ensuring compliance with applicable grid requirements.
  
• Oversee loop testing and energization of step-down transformers and rectifiers associated with the process electrical trains.
  
• Coordinate earthing resistance measurements, initial electrical inspections and protection relay activities required for grid connection.
  
• Execute phased energization of LV switchboards, including the use of temporary supplies where required, and manage the transition to permanent power prior to process start-up.
  
• Supervise the activities of electrical vendors and site subcontractors.
  
• Coordinate Inspection and Test Plans and ensure proper treatment and closure of electrical non-conformities.
  
• Perform end-to-end loop checks and protection interlock verifications between field equipment, switchgear and control systems.
  
• Support the commissioning of electrical shelters and associated electrical equipment.
  
• Drive system handover from Construction to Commissioning, ensuring punch-list clearance and compliance of as-built documentation.
  
• Verify that all electrical systems are ready for energization and commissioning in accordance with approved procedures and project requirements.
  
• Coordinate closely with HSE, QA/QC, construction and commissioning teams to ensure safe and controlled execution of electrical activities.
  
• Provide clear daily and weekly reporting on progress, issues, technical risks and required corrective actions.
  
• Contribute to the overall commissioning planning and sequencing of electrical systems.
  
• Support troubleshooting and resolution of complex electrical commissioning issues.
  

Requirements

• Minimum 10 years of proven hands-on experience in electrical commissioning within complex industrial power systems.
  
• Expert-level experience in commissioning of HV and MV systems.
  
• Strong experience in the commissioning of HV GIS switchgear, MV switchgear, power transformers, protection systems and distribution networks.
  
• Good experience with power conversion systems, rectifiers, reactive power compensation and harmonic filtering.
  
• Proven experience in electrical pre-commissioning, energization and functional testing.
  
• Good knowledge of grid connection requirements, protection systems and relay coordination.
