Substation Manager

Mission

The Substation Manager provides independent technical oversight, engineering assurance, and quality monitoring for all HV/MV substation works executed by the EPC Contractor. This includes GIS/AIS, transformers, MV switchgear, AC/DC systems, protection and control, SCADA, cabling, and commissioning. The role ensures compliance with IFC drawings, technical specifications, IEC/IEEE standards, and grid requirements. This is OE role (monitoring, verifying, reporting).

Key Accountabilities

1. Engineering Oversight & Technical Assurance

• Monitor EPC installation of GIS/AIS, transformers, MV switchgear, protection panels, AC/DC systems, and cabling.

• Verify work compliance with IFC drawings, project specifications, OEM manuals, and IEC/IEEE standards.

• Identify design deviations, technical risks, and non-conformities and escalate accordingly.

• Review EPC shop drawings, wiring diagrams, protection schemes, SCADA mappings, and installation procedures.

2. Protection & Control Oversight

• Review protection coordination studies, HV equipment installation, relay settings, and logic designs.

• Verify implementation of interlocking schemes and control logic.

• Review and approved test procedures, and witness protection testing (secondary injection, relay configuration, trip circuits, interlocking, SCADA point checks).

• Ensure EPC testing aligns with grid code and utility requirements.

3. QA/QC & Testing Verification

• Monitor EPC QA/QC activities according to FQP, CL, ITPs and approved QA plans.

• Witness insulation resistance tests, Hi-Pot tests, contact resistance, transformer acceptance tests, MV switchgear tests, and integration tests.

• Review NCRs, corrective actions, and verify technical closure.

• Confirm accuracy of as-built drawings.

• Review and approved QA/QC documents ITP, FAT, FQP, CL, MS and material submittal.

•Perform Site inspection and issue IR and MIR for material inspection.

Long Description

4. Commissioning & Energization Oversight

• Review EPC pre-commissioning and commissioning procedures for Electrical systems.

• Validate readiness for energization through systematic checks and walkdowns.

• Track and verify closure of commissioning punch lists.

• Support Owner with energization readiness documentation.

 5. Interface Coordination

• Coordinate substation interfaces with civil, Electrical, commissioning SCADA, telecom, and grid operator teams.

• Ensure EPC provides accurate interface details and proper sequencing.

• Resolve multidisciplinary technical conflicts.

 6. Progress Verification

• Verify EPC progress (installation, cable pulling, terminations, testing) against planned milestones.

• Validate progress claims with physical evidence.

• Prepare daily/weekly reports on progress, quality, testing, risks, and required actions.

7. OE Team Collaboration

• Guide OE electrical, QA/QC, SCADA, and commissioning engineers on inspection priorities.

• Support the Site Manager in executing the weekly surveillance plan.

• Consolidate technical findings for Owner decisions.
