Coolum Beach is on the Energex network, which covers south-east Queensland. For small customers a basic connection allows 5 kW of export per phase (5 kW single-phase, 15 kW three-phase). A Dynamic Connection, available since July 2023, lets the limit flex up to 10 kW per phase when the network has capacity.
South-east Queensland has some of the highest rooftop solar uptake in the world, so export capacity can change street by street. The suburb snapshot below tells you how the area is tracking; the checker tells you about your own transformer.
None of the 30 transformers with published data are currently curtailing exports during the day, which is a good sign for anyone adding solar in Coolum Beach now.
Upstream headroom
The nearest zone substation, Coolum (1.3 km away), reports 37.4 MVA of export capacity available against a 59.5 MVA rating. Street-level transformers, not the substation, are the usual bottleneck.

Export limits in Coolum Beach, answered
- Can I export solar to the grid in Coolum Beach?
- In most cases, yes. Of the 30 local transformers with published data, 90% still have at least 20% of their export capacity available, which normally means the standard 5 kW per phase export limit applies. 10% are getting tight or constrained, so it's worth checking your exact address above.
- What export limit will I get in Coolum Beach?
- On a basic Energex connection it's 5 kW per phase: 5 kW for a single-phase home and 15 kW on three-phase. A Dynamic Connection can raise that to 10 kW per phase when the network has room. On a transformer that's nearly full, a new fixed connection may be limited to 1.5 kW, which is another reason to ask for a Dynamic Connection.
- Where does this data come from?
- From Energy Queensland's public Network Load & Export Capacity Map, which Energex publishes for engineers and installers. The suburb figures on this page are a snapshot of the map taken on 15 September 2026 for transformers within 1.5 km of Coolum Beach. The address checker queries the map live.
- Is a battery worth it if my export is limited?
- Usually the case for a battery gets stronger, not weaker. Export limits cap what you sell back at a low feed-in rate; a battery stores that power for the evening when you'd otherwise buy it at full price. We model both options with your bill before recommending anything.
