Every generator connecting to the National Electricity Market must meet AEMO's Generator Performance Standards (GPS) under the National Electricity Rules. For solar farms and BESS projects, this process is directly tied to your project's financial and operational milestones.

ElectraGlobe manages the entire GPS application process, from initial assessment through to AEMO approval.

What Are AEMO Generator Performance Standards?

Generator Performance Standards are the minimum technical performance requirements a generator must demonstrate to AEMO before it can be registered to operate in the NEM. They are defined in Chapter 5 and Chapter 5A of the National Electricity Rules and cover a wide range of performance dimensions.

What Generator Performance Standards Cover

Reactive power capability: the reactive range the plant can hold at the connection point across its operating envelope
Frequency response: plant behaviour during over- and under-frequency events, including primary frequency response
Fault ride-through: staying connected and supporting the network through voltage disturbances
Power quality: harmonics, voltage fluctuation and flicker within the limits set for the connection point

For new utility-scale solar and BESS projects, GPS compliance must be established and agreed with AEMO before the project can progress to commissioning and commercial operation.

What ElectraGlobe Delivers

Workstream	What we deliver
GPS application and approval	Application preparation in full compliance with NER Chapter 5 and 5A Negotiated GPS agreements with AEMO under NER 5.3.10 Technical assessments of altered system performance against registered standards GPS updates and registration for modified or repowered assets
Compliance testing	Dynamic Model Acceptance Testing (DMAT) planning and execution GPS compliance testing during commissioning Hold point test simulations and results validation Troubleshooting and resolution of AEMO non-conformance findings
BESS and market registration	Metering requirements assessment for alternative BESS operating approaches Connection point suitability review for alternative operating philosophies Runback and curtailment scenario identification and analysis Coordination with AEMO for BESS registration and market participation

We take on the full GPS scope or step in at a single stage, whether that is a stalled application, a DMAT programme, or a non-conformance raised during commissioning.

BESS Operating Strategies

Battery projects raise questions a solar farm does not. How the asset is metered, where the connection point sits, and how it responds to a runback signal all shape what can be registered and what the plant is allowed to do in the market.

We review the proposed configuration against the operating philosophy the project is being financed on, identify where the two diverge, and carry the resolution through to AEMO registration.

Why GPS Applications Require Specialist Support

The GPS process involves detailed technical submissions, dynamic modelling, and ongoing negotiation with AEMO across a timeline that can span months.

Errors or gaps in the application can trigger additional information requests, re-testing, and project delays that have direct cost implications. ElectraGlobe's experience with AEMO processes means we anticipate requirements before they become issues.

If you have a GPS application in preparation, in review, or already generating queries from AEMO, we can tell you quickly where the real risks sit.
