Key Responsibilities

• Engineering & Pre-Commissioning Planning:
  • Review and provide inputs to the engineering team regarding grid compliance, WTG controller limits, and machine-specific challenges.
  • Participate in Factory Acceptance Test (FAT) reviews of WTG control and protection systems where applicable.
  • Develop WTG commissioning procedures, method statements, and risk assessments.
  • Coordinate commissioning sequence planning with EPC, OEM, and grid operators.
• Mechanical & Electrical Commissioning Coordination:
  • Supervise and verify the correct completion of mechanical erection, torquing, alignment, and lubrication.
  • Ensure proper electrical installation, including LV, MV, transformers, and grounding systems.

• Electrical Energization:
  • Lead pre-energization checks, including insulation resistance tests, grounding continuity, phase sequence, and voltage checks.
  • Coordinate transformer energization and LV/MV energization.
  • Execute first grid synchronization and progressive power ramp-up.
  • Ensure safety compliance during live tests and rotating machinery operation.
• Control, Protection & Grid Compliance:
  • Validate WTG controller parameters as per grid code and Power Plant Controller (PPC) philosophy.
  • Coordinate Low Voltage Ride Through (LVRT) / High Voltage Ride Through (HVRT), frequency ride-through, and reactive capability tests.
  • Verify pitch-based power regulation and ramp-rate control.
  • Confirm correct response to curtailment, trip, and fault conditions.
• Trial Operation & Handover:
  • Support trial runs, availability tests, and performance acceptance.
  • Review SCADA data, alarms, and event logs.
  • Close commissioning punch points and support Commercial Operation Date (COD) documentation.

Experience Requirements

• A minimum of 5 to 10 years of experience in testing and commissioning, specifically with Wind Turbine Generators (WTGs) in utility-scale wind power projects.
• Demonstrated expertise across mechanical, electrical, control, protection, and grid-interface systems of WTGs.

Work Environment

This is a full-time position based in Riyadh, Saudi Arabia, requiring on-site presence for project execution and coordination within utility-scale wind power developments.
