Who supplies electricity in Adelaide?
SA Power Networks owns and operates the poles and wires across Adelaide (All of South Australia). They are the same whichever retailer bills you, so switching retailer never changes the physical connection.

How much does electricity cost in Adelaide?
The reference price for SA Power Networks is $2,334 a year at 4,000 kWh. Retailers often advertise a percentage off this figure, so here is what a discount is worth.
| Reference price | $2,334 a year |
| An offer 5% under the reference | about $2,217 a year |
| An offer 15% under the reference | about $1,984 a year |
| Possible saving | about $117 to $350 a year |
Simple arithmetic on the reference price, for illustration. Your bill depends on your usage and plan.
The Solar Sharer Offer, from 1 July 2026, gives smart meter households three hours of free electricity in the middle of the day (12pm to 3pm in South Australia). Check the tariff against your own usage before opting in; see our free power guide.
How good is the internet in Adelaide? What the NBN looks like
Across Adelaide, the NBN dataset classifies 619,096 premises. Which technology you are on matters more than which provider you pick, because the technology limits your speed tiers.
- Fibre to the premises: 34.8%
- Cable (HFC): 35.8%
- Fibre to the curb: 7.2%
- Fibre to the building: 1.1%
- Fibre to the node: 21.1%
35% of classified premises are on fibre to the premises and 21% on fibre to the node. The split varies by region: North has the most fibre to the premises (39%), and South has the most fibre to the node (30%), the technology most likely to limit speeds. Check your own address before choosing a speed tier.

Moving to Adelaide? Getting power and internet connected
Tell your chosen retailer your move-in date a few business days ahead and they arrange the connection with the network. Ask which NBN technology your address has before you pick an internet plan: fibre to the node or fibre to the curb homes can need an installer visit, so book earlier. New builds should confirm with the builder that the meter and NBN connection are ready.
Our take on Adelaide
With SA Power Networks as the network, the price differences you can act on come from the retailer, not the poles and wires. A 15% discount on the $2,334 reference price saves about $350 a year, so check the supply charge and any conditions, not only the percentage. 35% of Adelaide premises are on fibre to the premises, so on internet the choice is mostly about price and contract terms.
