How we ranked these plans
Every retailer must publish its plan pricing in machine-readable form under the Consumer Data Right, via the Australian Energy Regulator's Energy Made Easy platform. We surveyed all 78 retailer brands in the register; 23 sell in the Endeavour Energy zone, and we priced 54 current single-rate residential market offers at 4,900 kWh a year - the AER Default Market Offer 2026-27 reference usage for this zone. Rankings use unconditional prices: guaranteed discounts are applied, pay-on-time and direct-debit discounts are not.
We excluded 17 wholesale-price plans (their published rates are estimates, not guaranteed - see our Amber Electric review for how those work) and 44 plans restricted to seniors, members, or specific hardware. No retailer pays for placement. The full method lives on our Electricity Plans hub.
How electricity pricing works in Wollongong
Wollongong and the Illawarra sit on the Endeavour Energy network - different poles and wires from Sydney's Ausgrid, with different charges, which is why the same retailer quotes different rates an hour up the road. Endeavour's zone also takes in greater western Sydney, the Blue Mountains and the Southern Highlands, so the prices in this table apply from Thirroul to Penrith. The reference usage is higher here too: 4,900 kWh a year against Ausgrid's 3,900, reflecting bigger detached homes and less apartment stock.
Your bill has two levers. The usage rate is what you pay per kilowatt-hour consumed. The daily supply charge is a fixed cost for being connected, regardless of usage. Low-usage households should weight the supply charge more heavily; bigger consumers - which at 4,900 kWh reference usage is most Illawarra households - should chase the lowest usage rate.
Rooftop solar is already doing heavy lifting locally: our Clean Energy Regulator data counts 39,887 solar systems across Illawarra postcodes. Every kWh you generate instead of importing beats any discount in this table - see our solar savings calculator and battery payback calculator for Illawarra rates.
Watch the conditional discounts
A conditional discount is a discount you only receive if you do something: pay on time, set up direct debit, or receive bills by email. Retailers advertise the discounted price, but the moment you miss one payment you are billed at the full rate - and on some plans that full rate is above the market average. The Australian Energy Regulator has repeatedly flagged pay-on-time discounts as functioning like late-payment penalties.
That is why our table ranks on unconditional prices. Plans in the table marked with "conditional discount available" can work out cheaper than their listed cost if you reliably meet the conditions - just make the comparison with your eyes open. The same logic applies to sign-up credits: a $100 credit on a plan that costs $200 more per year is a loss by month seven.
Best solar feed-in tariffs in Wollongong
A feed-in tariff (FiT) is the credit you receive for each kWh of solar you export to the grid. Wollongong retailer feed-in rates currently run from 0 to about 5.5c/kWh. The trap: high-FiT plans usually pair with higher usage rates, so they only win for homes exporting far more than they import.
| Provider | Plan | Feed-in rate | Est. annual cost (before solar credits) |
|---|---|---|---|
| CovaU | Freedom Residential Single | 5.5c/kWh | $2,360 |
| Diamond Energy | Diamond Everyday - Single Rate | 3.1c/kWh | $2,328 |
| OVO Energy | The One Plan | 3c/kWh | $2,029 |
| Alinta Energy | HomeDeal Smart - Single Rate | 3c/kWh | $2,049 |
| EnergyAustralia | Flexi Plan | 3c/kWh | $2,049 |
With feed-in rates this low, exporting solar earns a fraction of what avoiding imports saves. That gap is the economic case for home batteries - store your excess instead of selling it for cents. See what low feed-in rates cost you with our solar export loss calculator, or compare NSW VPP programs that pay battery owners for grid support.
How to switch electricity providers in Wollongong
- Grab a recent bill. You need your address, your NMI (the meter number on the bill), and your actual usage to compare accurately.
- Check the table above, then verify. Confirm the current rate on the retailer's own site - retailers reprice through the year.
- Sign up online. Takes about ten minutes. The new retailer manages the transfer; there is nothing to disconnect and no outage.
- Use the cooling-off period if needed. You have ten business days to cancel without penalty.
- Settle the final bill. Your old retailer bills you to the switch date. Check it against your meter reading.

Cheap electricity in Wollongong: FAQs
Who has the cheapest electricity in Wollongong? ⌄
As of July 2026, the cheapest widely available single-rate plan in Wollongong is 1st Energy's 1st Opal - Single Rate at about $1,861 a year for a home using 4,900 kWh. Rankings shift as retailers reprice, so check the current table above before switching.
Are Wollongong electricity prices the same as Sydney? ⌄
No. Wollongong sits on the Endeavour Energy network, while most of Sydney is on Ausgrid, and each network has its own poles-and-wires charges baked into retail rates. The same plan is priced differently in each zone. Greater western Sydney shares the Endeavour network, so these prices apply there too.
What is the reference price for electricity in NSW? ⌄
The reference price is the annual cost cap the Australian Energy Regulator sets each July for a typical customer on a standing offer, known as the Default Market Offer. Retailers must express discounts against it. The cheapest Wollongong market offers sit well below it - currently around $1,861 a year.
Should I pick the plan with the highest solar feed-in tariff? ⌄
Rarely. A feed-in tariff is the credit you receive per kWh of solar exported, and high feed-in plans usually carry higher usage rates or supply charges that cost more than the extra credits earn. Compare the whole annual cost at your usage and export levels, not the headline feed-in rate.
How do I switch electricity providers in Wollongong? ⌄
Sign up with the new retailer online with your address and a recent bill handy - it takes about ten minutes. The new retailer handles the transfer, there are no disconnection works, and supply is never interrupted. You get a ten business day cooling-off period, and your old retailer sends a final bill.
