Senior Power System Secondary Engineer

The Senior Power System Secondary Engineer acts as the technical authority on behalf of the projectdeveloper, providing independent oversight, review, and verification of all secondary systems engineering across utility-scale renewable energy plants (Solar PV, Wind) and Battery Energy Storage Systems(BESS). The role is pivotal in ensuring that designs delivered by EPC contractors and specialistconsultants are technically sound, safe, cost-effective, and fully compliant with International Best Practices, utility / TSO requirements, and applicable International Standards (IEC, IEEE/ANSI).

• Lead the review and verification of all secondary design deliverables — including Single Line Diagrams (SLDs), Protection & Metering Diagrams (PMDs), Block Logic Diagrams (BLDs), AC/DC schematics, and LV System Design Documents — for HV substations and renewable plants.

• Verify protection and control philosophies, including relay settings, selectivity analyses, and coordination studies (short-circuit calculations, CT/VT sizing) prepared by consultants and EPC contractors.

• Review and approve interlocking schemes, bay-level logic, and station-level automation across switch gear, transformers, feeders, and renewable energy plant interfaces.

• Approve substation automation and SCADA architectures, ensuring correct implementation of IED logic, signal lists, and interlocking schemes at bay and station levels.

• Oversee the integration and configuration of communication protocols — IEC 61850 (GOOSE/SV/MMS), IEC 60870-5-104, and DNP3 — governing data flow between Plant Power Controllers (PPC/EMS), substations, and utility control centers.

• Review IED configurations, substation HMI displays, and historian / data management architectures for completeness and compliance.

• Review and validate communication and telecommunication architectures, including managed network design (VLANs, PRP/HSR redundancy), cybersecurity policies (IEC 62351 / NERC-CIP aligned), and tele-protection performance requirements.

• Ensure strict adherence to international standards and grid codes (IEC, IEEE/ANSI) by performing technical audits and vetting technical submissions to Transmission / Distribution System Operators (TSO/DSO).

• Manage technical interfaces and coordinate between EPC contractors, engineering consultants, OEMs, and the grid operator to ensure a coherent and optimized secondary systems design.

• Provide technical governance during critical project phases, including witnessing Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT), and reviewing commissioning procedures for all secondary systems.

• Review and approve test plans, testing protocols, punch lists, and commissioning records to ensure safe energization of HV substations and plant systems.

• Act as the Owner’s Engineer representative in te

• Bachelor’s or Master’s degree in Electrical Engineering, Power Systems, or a closely related field.

• Professional Engineering registration (PE / CEng or equivalent) is an advantage.

• 8+ years of engineering experience with a demonstrable focus on substation secondary systems design and delivery.

• Significant experience in a developer, owner’s engineer, or utility role with direct responsibility for managing and challenging EPC contractor deliverables.

• Proven track record on grid-connected utility-scale renewable energy projects (Solar PV, Wind) and/or Battery Energy Storage Systems (BESS).

• Experience working across the full project lifecycle from FEED and detailed design through to FAT, SAT, and commercial operation
