Every home gets a smart meter by 2030 — and you can’t opt out

What was decided, and when

On 28 November 2024 the Australian Energy Market Commission published a final determination and final rules accelerating smart meter deployment across the National Electricity Market. The rules require universal smart meter deployment by 2030 — and, importantly, they removed the ability to opt out. If your retailer contacts you about installing a smart meter, you will not be able to refuse it.

The rule-maker’s case rests on system-wide benefits: an independent review put the net benefit of reaching 100% of households by 2030 at $507 million across the participating National Electricity Market regions, which include New South Wales, Queensland, the ACT and South Australia. Victoria completed its own rollout years earlier under a separate state programme.

For most households this will simply happen: a meter exchange takes under an hour, the power is off briefly, and nothing else visibly changes. The consequences that matter are what the meter enables afterwards.

What a smart meter actually changes

An old accumulation meter records one number: total energy consumed since it was installed. Somebody reads it periodically, and your bill is the difference between two readings. It knows nothing about when you used power.

A smart meter records consumption in intervals, typically every half hour, and reports remotely. That single change is what makes time-of-use tariffs, demand tariffs, the Solar Sharer free-power window, accurate solar export measurement, and same-day move-in connections possible. It also ends estimated bills, which is a genuine improvement for anyone who has ever been billed on an estimate and then hit with a catch-up.

The flip side is that interval data makes new tariff structures possible, and not all of them suit every household. A tariff that charges more in the evening peak rewards a household that can shift load and penalises one that cannot.

The protections you keep — and should use

The rules came with customer safeguards that are worth knowing, because they are the part retailers are least likely to volunteer. For two years following the installation of a smart meter, a customer cannot be moved to a new tariff without giving explicit informed consent. That is a meaningful window: you are not going to be silently shifted onto a time-of-use structure the month after your meter changes.

After that period, a retailer wanting to change your tariff must provide historical bill comparisons — showing what your bills would have been under the new tariff — along with practical information on understanding and managing your usage. In other words, they have to show you the arithmetic on your own history rather than simply asserting the new tariff is better.

The rules also let jurisdictions require designated retailers to offer flat tariff options to customers with smart meters, so a smart meter does not automatically mean a time-varying bill.

Turning interval data into a lower bill

The real opportunity is that a smart meter turns "which tariff suits me" from a guess into a calculation. Once your usage is recorded in half-hour intervals, the cost of any tariff structure on your actual pattern can be computed exactly rather than estimated from a quarterly total.

Most households never see that data, because it sits with the retailer and is rarely presented usefully. You are generally entitled to request your own interval data — often as a file — and it is worth doing: it is the difference between being told a time-of-use plan suits you and checking whether it does.

EnergySorted reads interval data directly and costs every plan on your real usage shape, including time-of-use and demand structures, so the answer comes from your own half-hours rather than from an average household. Our guide to time-of-use vs single-rate explains which pattern suits which tariff, and how to read your electricity meter covers what the display is telling you.

What to do when yours is replaced

Three things. Take a photo of the old meter’s final reading before the exchange, so you have your own record if a final bill is ever disputed. Confirm in writing what tariff you are on immediately after the change, and that it has not moved. And re-compare your plan once you have a few months of interval data, because that is the first point at which the comparison can be genuinely precise for you.

If you have solar, check that export is being measured correctly after the exchange — a smart meter measures import and export separately, and a misconfigured meter shows up as missing feed-in credits rather than as an error message. Compare your plan on real usage once the data exists, or use the free electricity bill estimator in the meantime.
