Electricity prices in the SA Power Networks area

SA Power Networks looks after the poles and wires in all of South Australia's main grid. Here's what a household pays for a year there: the Default Market Offer, and every single-rate plan retailers publish, all priced at the same 4,000 kWh.

The default offer

$2,334

A year, for 4,000 kWh, from 1 July 2026. That's $33 more than last year. It's the most a retailer can charge you on a standing offer.

A typical plan

$2,217

That's $117 a year less than the default offer. 77% of 109 plans from 21 retailers cost less than the default offer. The lowest is $1,201.

What every plan costs

Same usage, same area, from $1,201 to $2,859 a year. That's a gap of $1,658 for the same electricity.

Coloured bars are plans that cost less than the default offer of $2,334. 10 plans also offer a discount if you pay on time or by direct debit. We haven't counted it, so they could cost less.

On a time-of-use plan?

Time-of-use plans charge more at busy times, like late afternoon, and less overnight or in the middle of the day. The default offer for one here is $2,276 a year. A typical time-of-use plan is $2,162, and 96% of 116 plans cost less than the default.

Priced with the regulator's own pattern of when a typical household here uses power through the day. If you use more at peak times, you'll pay more than this; if you can move your use to cheaper times, less.

Got a controlled load?

A controlled load is a separate meter for something like an electric hot water system, which only gets power at set times, often overnight, at a lower rate. With one, a typical household here uses 1,800 kWh a year on it, on top of 4,000 kWh for everything else. The default offer for both is $2,734 a year. A typical plan with a controlled load is $2,596, and 94% of 90 plans cost less than the default.

Priced on the plan's flat rate plus its "Controlled Load 1" tariff, the way the regulator works out the default offer.

Never switched? Check your plan

If you moved in and never picked a plan, or haven't changed in years, you may be on a standing offer. A typical standing offer here costs $2,334 a year. Moving to a typical market plan would save about $117 a year, and up to $1,133 on the lowest-priced plan.

Look at your bill. It must say how your price compares with the DMO: for example, "5% less than the reference price". Higher than the default offer means you could do better.

Check again each July. That's when the default offer and most prices change.
