Responsibilities
Site Commissioning & Energization
Lead step-by-step energization sequences from MV/HV incoming feeders through MV skids, transformers, PCS, and battery systems, coordinating with grid operators and internal safety supervisors.
Direct the integration and interoperability verification between PCS, BMS, and MV transformers, including permissive logic, protection coordination, and communication handshake validation.
Issue Hold/Go decisions autonomously during commissioning milestones; document all deviations with technical justification and corrective actions.
Execute and oversee pre-commissioning checks: insulation resistance, continuity tests, protection relay functional tests, transformer turns ratio, and PCS self-tests.
Act as primary technical counterpart to OEM commissioning engineers (NR Electric, Kehua, Huawei, SMA, and others) during site visits, FAT, and SAT activities.
Coordinate with the SCADA Engineer at the commissioning boundary: electrical systems ready for service before handoff to SCADA integration and telemetry verification.




Conduct all commissioning activities in full compliance with Trina Storage’s EHS policies and site-specific safety plans; apply and enforce safe work practices during energization, HV/MV switching, and testing activities.
Documentation & Technical Governance
Sign commissioning protocols, ITPs (Inspection and Test Plans), punch lists, and as-built records; ensure completeness of commissioning packages for Substantial Completion milestones.
Identify, document, and track Non-Conformance Reports (NCRs) and technical deviations through resolution; coordinate with EPC and OEM as required.
Issue commissioning completion reports for each project, including test results, open items, and recommendations for O&M; handover.
Maintain an updated library of commissioning procedures, lessons learned, and pre-manufacturing requirements derived from executed projects.
Support warranty engineering by providing technical evidence and
