Business electricity in South Australia
South Australia is served by a single distribution network, SA Power Networks, which simplifies one part of the comparison: every retailer serving your site passes through the same network charges. What differs between offers is the retail component.
South Australia also has a very high share of renewable generation and a high rate of business solar uptake, which affects both the shape of wholesale prices and the value of exporting power during the day.

One network, many retailers
Because SA Power Networks is the only distribution business in the state, network tariffs are consistent across retailers for an equivalent connection. This makes the retail offer — the energy rates, the daily supply charge and any feed-in rate — the deciding factor when comparing.
Your site's network tariff still matters, because it sets how the network component is calculated: a demand tariff and a flat energy tariff on the same site produce different total costs.
Why timing matters more in South Australia
With a high proportion of solar generation in the state, the wholesale cost of electricity varies significantly across the day, and some plans expose part of that variation to the customer through time-of-use pricing.
For a site that can shift flexible load — refrigeration, hot water, charging — a time-of-use plan can be worth modelling against a flat plan. The comparison has to be run on your actual usage shape, which is why the hourly or interval data on your bill is more useful than an annual total.
How to compare plans in SA
Start from a recent electricity bill for the site you want to compare. The bill gives us the usage, the billing period and the network tariff that a comparison for a South Australia site needs in order to reflect how you are actually charged.
