Frequently asked questions
- Why is a SA Power Networks bill different from other areas?
- Poles-and-wires costs differ by network. SA Power Networks covers South Australia (whole state), and its network charges are built into the AER Default Market Offer figures for this zone — so the same usage costs a different amount on a neighbouring network. Compare the other SA zones or the national table below.
- Does the reference price cap what I pay?
- Not exactly — it caps what retailers may charge a default (standing-offer) customer at the model usage level of 4,000 kWh/year. Market offers usually price below it, so treat $2,334 as the benchmark your own plan should beat.
- What's controlled load?
- A separately metered circuit — usually electric hot water — that the network can energise off-peak in exchange for a cheaper rate. In SA Power Networks's zone the controlled-load usage rate is 22.2c/kWh, well under the anytime rate of 41.9c/kWh.
- When do these prices change?
- Every 1 July. The AER Default Market Offer 2026–27 (DMO 8) applies from 1 July 2026 to 30 June 2027; the next reset is 1 July 2027. This page is re-verified against the new determination each year.
