Job Location : Saudi Arabia

�Job Title

Testing & Commissioning Engineer – HV / EHV Substations
(Substation Maintenance Engineers with strong testing exposure are encouraged to apply)

� Job Purpose

To lead and execute testing and commissioning activities for HV/EHV substations (220 kV / 380 kV / 400 kV), covering primary yard equipment, secondary protection & control systems, substation automation, and grid interface, ensuring safe energization in compliance with utility standards, IEC/IEEE codes, and project specifications.

The role requires strong hands-on site experience across complete substation systems, not limited to individual equipment.

� Key Responsibilities

1) HV / EHV Substation Testing & Commissioning

Execute and lead testing activities across complete substation installations, including:

Primary Equipment (HV / EHV Yard & Switchgear)

• AIS / GIS systems at 220 kV, 380 kV, and 400 kV

• HV/EHV Circuit breakers, isolators, earthing switches

• CTs and VTs (ratio, polarity, burden, functional checks)

• Busbars, feeders, earthing systems etc…

• Power transformers (testing limited to integration, protection interface, and energization readiness)

Ensure correct phasing, interlocking, clearances, earthing continuity, and readiness for first energization of the HV/EHV substation.

2) EHV Protection, Control & Secondary Systems

Testing and commissioning of EHV protection and control schemes, including:

• Distance protection (multiple zones)

• Line differential protection (PLCC / fiber-based)

• Transformer differential protection

• Busbar protection schemes

• Overcurrent and earth fault protection

• Bay control units (BCU) and control panels

Perform:

• Primary and secondary injection testing

• End-to-end protection testing

• Trip circuit supervision and interlocking verification

• Relay setting verification and coordination

Experience with ABB, Siemens, GE, Schneider, SEL or equivalent EHV protection platforms is mandatory.

3) Substation Automation, SCADA & Communication

• Commissioning of EHV substation automation systems (SAS)

• SCADA, RTU, and bay-level communication testing

• Signal validation between yard, control room, and remote control centers

• Time synchronization (GPS/IRIG-B, SNTP)

• Event, disturbance recorder, and SOE verification

4) Energization & Grid Interface (Critical Scope)

• Lead and support EHV energization activities in coordination with grid authorities

• Prepare energization sequences, checklists, and safety clearances

• Coordinate live-grid switching, shutdowns, and re-energization

• Troubleshoot protection trips, alarms, and communication issues during first energization and trial operation

5) Supervision & Stakeholder Coordination

• Lead teams of commissioning engineers and technicians

• Coordinate with:

  • EPC engineering teams

  • OEM specialists

  • Utility / transmission operator representatives

  • Consultants and third-party inspectors

• Participate in technical, energization, and HSE meetings

• Support utility inspections and final handover activities

6) Documentation & Commissioning Deliverables

• Prepare and review:

  • EHV-specific method statements and risk assessments

  • Commissioning and energization procedures

• Compile:

  • Detailed EHV test reports

  • Punch lists and clearance certificates

  • Final commissioning and energization dossiers

• Support red-line and as-built documentation

7) Compliance, Quality & Safety

• Ensure compliance with:

  • IEC, IEEE, NEC standards

  • Transmission utility specifications

• Enforce strict EHV safety and permit-to-work systems

• Promote safe working practices during live-grid operations

� Candidate Profile

Mandatory

• Bachelor’s Degree in Electrical Engineering

• Minimum 5 years of experience in EHV (220 kV / 380 kV / 400 kV) substation testing & commissioning or maintenance

• Proven hands-on experience with HV/EHV protection schemes and grid energization

• Strong understanding of transmission-level substations and live-grid environments

• Familiarity with IEC standards and utility procedures

Preferred / Added Advantage

• Experience working directly with transmission utilities or major EPC contractors

• Prior involvement in first energization of EHV substations or transmission bays

• Electrical safety / commissioning certifications (NEBOSH or equivalent)

• Experience in OHTL–substation interface commissioning

This role is not suitable for LV/MV-only or plant-based engineers. Candidates must have direct experience on 220 kV and above HV/EHV substations.
