• Confirm equipment ratings against short-circuit, load flow and cable/transformer loading studies, including PCS fault contribution during fault ride-through
• Drive battery yard layouts for maintenance access, fire separation, crane corridors and AS 2067 clearances
• Support the NER connection process, including Generator Performance Standards and grid-forming capability
• Coordinate power system studies (load flow, harmonics, reactive capability, dynamic performance) with OEM-supplied PSS®E and PSCAD models
• Lead safety-in-design for BESS hazards such as thermal runaway, LV arc flash, transformer failure and fire spread
• Review design packages at 30%, 80% and IFC, and support procurement with specifications, tender evaluations and vendor document reviews
• Oversee FAT, site testing, energisation, commissioning and R2/hold-point testing with the network service provider
