Canberra · Australian Capital Territory
In Canberra, commercial solar is a cost decision and nothing else
The whole territory sits on one network, and the ACT already contracts renewable supply equal to its electricity use. So rooftop solar here is judged on one thing: the power it stops you buying.

Incentives
What the ACT actually offers
There's no ACT rebate for commercial solar as such. The federal STC discount is the up-front reduction to plan around. The ACT's Sustainable Business Program offers co-funded rebates of up to $10,000 for energy and water upgrades at commercial premises, and it's worth checking whether a solar project falls within its scope before it goes into a budget.
The ACT also contracts renewable generation equal to its electricity use. That changes the argument for rooftop solar in Canberra: it is a cost decision, measured against the power you would otherwise buy, rather than a way of greening grid supply.

Connection
Connecting through Evoenergy
The whole of the ACT sits on one distribution network, run by Evoenergy. That makes the connection process more predictable than in a split metro like Sydney or Melbourne: one set of thresholds, one application process, one set of export rules.
Evoenergy sets the threshold where a commercial connection moves from a notification to a full application with an export assessment. Larger systems should expect that assessment and plan the timeline around it.

Winter
Size against the heating season, not just summer
Canberra's cold, clear winters mean heating load in the colder months and strong generation on clear days. A site whose load is dominated by winter heating needs its sizing checked against that season, not only against summer.
That matters more as sites move off gas. New gas connections have been blocked in the ACT since December 2023, including in commercial zones, and the territory plans to be off gas by 2045. A business that electrifies its heating adds winter load at exactly the time of year its panels produce least. A proposal sized on summer figures alone will overstate what the system covers across the year.
The full method is on the cost and payback page, and the installation page covers what happens once a proposal is accepted.
Questions
Canberra questions
Is there an ACT rebate for commercial solar?
Not for commercial solar as such. The federal STC discount is the up-front reduction to plan around. The ACT's Sustainable Business Program offers co-funded rebates of up to $10,000 for energy and water upgrades at commercial premises; whether a solar project fits its scope gets checked when you apply rather than assumed.
Who is the network operator in Canberra?
Evoenergy, for the whole of the ACT. That makes the connection process more predictable than in a split metro area: one set of thresholds, one application process and one set of export rules.
Is rooftop solar still worth it if the ACT grid is renewable?
On cost, often yes. The ACT contracts renewable generation equal to its electricity use, so rooftop solar in Canberra isn't really about greening your supply. It's about the power you stop buying. A site with daytime load still saves on every kilowatt-hour the panels cover, and that is the whole of the case here.
How much does commercial solar generate in Canberra?
Around 1,450 kWh per kW of installed capacity a year on a well-oriented roof. A 50kW system produces roughly 72,500 kWh annually. Winter output is well below summer's, which matters for a site whose load peaks in the heating season.

One recent bill is enough to size a system and price it. It costs nothing, and there's no obligation.
