Dynamic Model Standing Offer for Small Inverter Energy Systems (0–30 kVA)
Ergon Energy Network and Energex are inviting feedback on how we best support rooftop solar with a proposed Dynamic Model Standing Offer for small inverter energy systems (IES) (0-30kVA) for a delivery date of mid 2026.
This new Dynamic Model Standing Offer supports smarter, more flexible energy connections – allowing IES to maximise how much electricity they export, or import based on current network conditions.
What's changing?
If you are planning to install or upgrade small IES (0-30kVA), you’ll soon be able to choose from three connection options:
Dynamic Model Standing Offer (new and now cost free)
Our existing Static Model Standing Offer and Negotiated Offer remain unchanged.

What is a Dynamic Connection?
A dynamic connection allows eligible solar and storage systems to utilise more network capacity and only reduce their export or import limits at times of grid congestion. This helps:
Improve network reliability and utilisation
Support more renewable energy
Reduce the need for costly upgrades.
Be sure to watch our video on how a Dynamic Connection works and the benefits for customers:

Key Features of Dynamic Model Standing Offer
Export more energy: Up to 10kW per phase, compared to 5kW (or 2kW on SWER) with a Basic Static Model Standing Offer.
Minimum export guarantee: You will always be able to export at least 1.5kW, except in rare emergency events.
Install a larger system: On single-phase power, you can install up to 20kVA total (10kVA solar + 10kVA battery) without needing to upgrade to three-phase.
Note: If you are using a hybrid inverter with a dynamic connection on single-phase power, your total inverter capacity (solar + battery) must not exceed 10kVA. This means the combined size of your solar and battery inverters must stay within that 10kVA limit.
Import Limits: Set according to dynamic operating terms and technical standards applying only to enrolled storage and EV charging systems.
No network augmentation: The Dynamic Model Standing Offer applies only where no upgrades are needed.
Cost-effective: Makes better use of existing infrastructure, helping keep electricity prices lower.
Costs
Basic connections that do not require any upgrades/changes to our network are generally free of charge.
Our Connection charges are regulated and outlined in each distributor’s Connection Policy and ACS Price List, available on their network websites:
We are always interested in hearing the varied perspectives of customers, industry experts and stakeholders on a wide range of topics and issues including the Dynamic Model Standing Offer. Be sure to provide your feedback in our questionnaire below.
