Muchea BESS
Detailed design for the Muchea battery project on Western Power's network - part of APD Global’s growing WA storage portfolio.
APD Global works as BESS independent engineer, owner's engineer and design engineer across the full scope of grid connection and storage work: connection studies, system strength assessments, generator performance standard registration, SIPS design, primary and secondary engineering for battery substations, and construction oversight.
With more than 70 BESS assignments - battery grid connection work across Australia and New Zealand - APD has covered the range from small commercial installations to the largest grid-scale batteries in the Southern Hemisphere. Each project delivers the technical compliance that regulators, network owners and lenders need before the first cell is charged.
Independent engineer
On high-value, high-consequence storage projects - where lenders, government and network owners need an independent technical voice - APD operates as independent engineer on grid-scale battery projects. Waratah Super Battery is the headline case: 1,400 MWh, SIPS design across 28 sites, primary and secondary design review, live test witnessing.
GPS registration
Generator Performance Standard registration requires site tests, validated dynamic models and technical submissions that satisfy AEMO under the National Electricity Rules. APD Global’s Power Systems team has delivered GPS registration across the NEM and WEM for batteries, renewable generators and industrial plant.
Connection studies
Pre-application and formal connection studies for new generators and storage - system strength, fault levels, voltage stability, thermal capability, access rights and GPS compliance modelling.
From feasibility to first charge
Storage projects live or die on sequencing: the connection studies shape the plant design, the GPS shapes the control system, and the earthing and protection have to be proven before energisation. Because APD holds all of those disciplines in one house - studies, primary, secondary, protection, earthing, SCADA - the design intent survives from feasibility through to the first cell charging.

BESS & grid connection - the questions asked most
Frequently asked questions.
What is a BESS independent engineer?
An independent technical reviewer engaged by lenders, government or network owners on high-consequence storage projects - reviewing third-party design, witnessing tests and providing the assurance that the asset will perform before money and grid access commit. APD Global is independent engineer on Waratah Super Battery: 1,400 MWh, with SIPS design across 28 sites.
What is GPS registration?
Generator Performance Standard registration is AEMO's process for agreeing how a generator or battery must perform on the network under the National Electricity Rules - backed by site tests, validated dynamic models and technical submissions. APD's Power Systems team delivers GPS registration across the NEM and WEM for batteries, renewables and industrial plant.
What studies does a battery need before it can connect to the grid?
System strength, fault level, voltage stability and thermal capability studies, plus GPS compliance modelling - first at pre-application stage to shape the project, then formally as part of the connection application. BESS grid connection & studies →
What is a SIPS?
A System Integrity Protection Scheme - a fast, wide-area control scheme that detects severe network events and acts (for example, by dispatching a battery) to keep the system stable. APD designed the Waratah Super Battery SIPS across 28 sites, the shock absorber for Sydney, Wollongong and Newcastle.
