BESS Specialist HV

About this role

We’re looking for a BESS Specialist to be the technical lead on a utility-scale battery energy storage system connected to the high voltage network. In this role you’ll own the integration of battery and power conversion equipment with the MV collector system, HV substation and grid connection, from concept design right through to commissioning and handover. You’ll be the key link between the battery/PCS OEM, our primary and secondary design teams, the network service provider and the construction team. Some of your key accountabilities will include:

Lead the technical integration of OEM battery enclosures and PCS/inverter units into the balance-of-plant design

Define and verify the collector system: main power transformer, 33 kV switchboards, RMUs, step-up transformers and LV connections to the PCS

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
