• Review IFC drawings/SLDs, submittals, settings sheets, and ITP (Inspection & Test Plan).
• Build site-specific commissioning plans & scripts (pre-functional, functional, performance).
• Coordinator outages, permits, and witness tests with the PM, utility, and OEMs.

Commissioning Execution:
• Perform pre-functional tests: visual/torque, insulation resistance (megger), continuity, grounding, polarity/phase rotation, IR scans.
• Load and verify protection & controls settings (relays/PCS/inverters), BMS/EMS parameters, and nameplate data.
• Execute functional tests: trip checks, anti-islanding, volt-VAR/frequency-watt, droop/ride-through, EMS/PCS dispatch, alarms
• Run perfomance tests: BESS charge/discharge, round-trip efficiency, SOC calibaration/balancing, reliability run (e.g., 72-100 hr).
• Integrate and verify SCADA/telemetry (Modbus-TCP/RTU, DNP3; point0to-point checks, historian trends, alarm matrix).

Troubleshooting & Quality
• Diagnose and resolve issues across power, controls, and networking (firmware, comms wiring, IP addressing, time sync, CT/PT plarity).
• Open/close Non-Conformance Report (NCRs); drive Corrective and Preventative Action (CAPA) actions with OEMs/subs; maintain a live punch list.
