Senior Power System Secondary Engineer Renewable Energy & BESSProject

Job DescriptionRoles & ResponsibilitiesThe Senior Power System Secondary Engineer acts as the technical authority on behalf of the project
developer, 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 specialist
consultants are technically sound, safe, cost-effective, and fully compliant with International Best
Practices, utility / TSO requirements, and applicable International Standards (IEC, IEEE/ANSI). Design Review & VerificationLead the review and verification of all secondary design deliverables — including Single LineDiagrams (SLDs), Protection & Metering Diagrams (PMDs), Block Logic Diagrams (BLDs), AC/DCschematics, and LV System Design Documents — for HV substations and renewable plants.Verify protection and control philosophies, including relay settings, selectivity analyses, andcoordination studies (short-circuit calculations, CT/VT sizing) prepared by consultants and EPCcontractors.Review and approve interlocking schemes, bay-level logic, and station-level automation acrossswitchgear, transformers, feeders, and renewable energy plant interfaces.Substation Automation & SCADAApprove substation automation and SCADA architectures, ensuring correct implementation of IEDlogic, 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 PowerControllers (PPC/EMS), substations, and utility control centers.Review IED configurations, substation HMI displays, and historian / data management architecturesfor completeness and compliance.Telecommunications & CybersecurityReview and validate communication and telecommunication architectures, including managednetwork design (VLANs, PRP/HSR redundancy), cybersecurity policies (IEC 62351 / NERC-CIPaligned), and tele-protection performance requirements.Standards, Compliance & Grid Code AdherenceEnsure strict adherence to international standards and grid codes (IEC, IEEE/ANSI) by performingtechnical 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.Testing, Commissioning & Project GovernanceProvide technical governance during critical project phases, including witnessing FactoryAcceptance Tests (FAT) and Site Acceptance Tests (SAT), and reviewing commissioningprocedures for all secondary systems.Review and approve test plans, testing protocols, punch lists, and commissioning records to ensuresafe energization of HV substations and plant systems.Act as the Owner’s Engineer representative in te
