Can I export solar to the grid in Toowoomba?

In most cases, yes. Of the 621 local transformers with published data, 99% still have at least 20% of their export capacity available, which normally means the standard 5 kW per phase export limit applies. 1% are getting tight or constrained, so it's worth checking your exact address above.

What export limit will I get in Toowoomba?

On a basic Ergon Energy 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 Ergon Energy 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 4.0 km of Toowoomba. 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.

Plenty of export capacity

Export capacity around Toowoomba is in good shape. 99% of local transformers with published data still have at least 20% of their export capacity available.

That's the suburb-level picture. Export limits are set per transformer, and a street can differ from the one behind it, so check your own address to get the answer that applies to you.

The local picture

How Toowoomba's transformers are tracking

Ergon Energy colours every transformer by how much of its solar export capacity is still free. This is the mix for the 980 transformers within 4.0 km of Toowoomba.

Toowoomba is supplied by Ergon Energy, the regional network that covers Queensland outside the south-east corner. Ergon's rules for small solar systems are the same as Energex's: a basic connection allows 5 kW of export per phase, and a Dynamic Connection can lift that to 10 kW per phase when the local network has room.

Regional feeders are often longer than city ones, so distance from the transformer matters more. Two houses on the same transformer can be offered different limits. That's why the checker looks at your specific address rather than the suburb as a whole.

3 of the 621 transformers with data (0%) are already curtailing exports for part of a typical day. On those, a Dynamic Connection is the difference between exporting most of the day and being capped.

Upstream headroom

The nearest zone substation, TOOWOOMBA CENTRAL 110/11KV SUB (0.3 km away), reports 24 MVA of export capacity available against a 88 MVA rating. Street-level transformers, not the substation, are the usual bottleneck.
