SA Power Networks is Adelaide’s electricity distributor, managing the infrastructure that delivers power to your home or business. They’re responsible for:

       

      • Maintaining power lines and poles

      • Managing emergency responses during outages

      • Installing and maintaining meters

      • Ensuring reliable power distribution across the network

      • Setting network tariff types and transfer rules

    While SA Power Networks handles the distribution, you have the freedom to choose from any energy providers who compete to offer you the best rates and services.

    Single rate tariffs

    If you are on Single Rate, it means that you are charged a flat rate for your electricity usage, no matter what time of day or night you are using it.

    Time of use tariffs

    If you’re on Time of Use, it means that the price of electricity (or the tariff you are charged) varies by time of day. It is more expensive to use electricity at peak times, and there are significant discounts for using electricity at other times.

    If you’re on Time of Use, SA Power Networks has three different periods that apply during the day.

    Note, your electricity provider may offer different time periods than the ones noted below.

    Peak period

    • 6:00am – 10:00am and 3:00pm – 1:00am

    These are traditionally the times of highest demand and when electricity costs the most.

    Off peak

    • 1:00am – 6:00am

    Pricing applied for a five-hour off-peak block every day, usually overnight. 

    Solar sponge

    • 10:00am – 3:00pm

    Also sometimes known as ‘shoulder’: This is usually the cheapest time to use energy – in the middle of the day when solar generation is typically at its highest.

    Demand tariffs Demand tariffs by default if customers with smart meters are assigned to network and may instead switch to time of use if they choose. Recently the AER limited the right of your energy provider to pass this network tariff through to you,

    If you have one of these tariffs, we can compare electricity providers Adelaide for you.
