What's a smart meter and why does it matter?
A smart meter records how much electricity you use (and export) every 30 minutes — and sends that data to your distributor automatically. No more estimated bills, and it unlocks time-of-use pricing.
Analog vs. smart: what changed
The old analog meters (the ones with the spinning disc) recorded a single cumulative number — total kWh consumed since the meter was installed. Your distributor sent someone to physically read that number every quarter, and your bill was the difference between two readings.
A smart meter (also called an interval meter or digital meter) records your electricity usage in 30-minute intervals, 48 times a day. It transmits that data to your distributor remotely — no meter reader visits needed.
Analog meter
One cumulative total. Read manually every quarter. Can only support flat-rate tariffs. No export measurement for solar.
Smart meter
30-minute interval data. Read remotely every day. Supports time-of-use and demand tariffs. Measures both import and export.
What a smart meter enables
- Time-of-use tariffs — because the meter knows when you used each kWh, your retailer can charge different rates for peak, off-peak, and shoulder periods.
- Accurate billing — no more estimated reads. Every bill reflects your actual usage for that exact period.
- Solar export measurement — the meter records electricity flowing in both directions, so your retailer can credit you accurately for what you export.
- Demand tariffs — the meter can identify your highest rate of draw (peak kW) within a measurement window.
- Remote connect/disconnect — your distributor can switch your supply on or off without a site visit (used for move-ins and move-outs).
Accessing your smart meter data
Your interval data belongs to you. There are several ways to access it:
Distributor portal
Most distributors (Ausgrid, Energex, Powercor, etc.) have online portals where you can download your interval data as a CSV or view usage charts. Search for your distributor’s name + “my energy data”.
Retailer app
Many retailers (AGL, Origin, EnergyAustralia) show daily and hourly usage in their apps, pulled from your smart meter data. Check your retailer’s app or online account.

Do I have a smart meter?
If you have solar panels installed after ~2010, you almost certainly have a smart meter — it’s required to measure exports. Otherwise, check your meter box: a smart meter has a digital display (not a spinning disc), and your bill should show interval-based charges or time-of-use rates.
In Victoria, all households were transitioned to smart meters by 2013. Other states are rolling them out progressively — new builds and solar installations get them first, and your distributor will replace your meter at its next scheduled change.
Why it matters for your bill
Without a smart meter, you’re stuck on a flat-rate tariff and can’t benefit from time-of-use pricing. If you can shift loads to off-peak hours (overnight, midday with solar), a smart meter combined with a time-of-use tariff could meaningfully reduce your bill. It also means your solar export credits are based on actual measured exports, not estimates.
