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; 22 sell in the Ausgrid zone, and we priced 53 current single-rate residential market offers at 3,900 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 Newcastle
Newcastle, Lake Macquarie, and most of the lower Hunter share the Ausgrid network with Sydney, so plan prices are identical to the capital's - a rare case where the big smoke subsidises nobody. The upper Hunter and New England sit on Essential Energy instead, where regional prices apply; if your postcode is past Singleton, compare at our regional NSW table.
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 - apartments, couples, solar homes - should weight the supply charge more heavily; bigger consumers should chase the lowest usage rate.
Newcastle's solar story is well ahead of Sydney's: our Clean Energy Regulator data counts 63,238 rooftop systems across local postcodes, roughly 0% of homes - detached housing stock and good sun do that. If you have a roof and no panels, the solar savings calculator will likely beat anything in the table above; if you already have panels, the battery payback calculator covers the next step.
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 Newcastle
A feed-in tariff (FiT) is the credit you receive for each kWh of solar you export to the grid. Newcastle retailer feed-in rates currently run from 0 to about 6.7c/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) |
|---|---|---|---|
| Red Energy | Red BCNA Saver | 6.7c/kWh | $1,613 |
| CovaU | Freedom Residential Single | 5.5c/kWh | $1,851 |
| Diamond Energy | Diamond Everyday - Single Rate | 3.1c/kWh | $1,899 |
| OVO Energy | The One Plan | 3c/kWh | $1,622 |
| Alinta Energy | HomeDeal Smart - Single Rate | 3c/kWh | $1,671 |
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 Newcastle
- 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 Newcastle: FAQs
Who has the cheapest electricity in Newcastle? ⌄
As of July 2026, the cheapest widely available single-rate plan in Newcastle is 1st Energy's 1st Opal - Single Rate at about $1,515 a year for a home using 3,900 kWh. Rankings shift as retailers reprice, so check the current table above before switching.
Are Newcastle electricity prices the same as Sydney? ⌄
Yes. Newcastle, Lake Macquarie and most of the lower Hunter sit on the Ausgrid network - the same poles and wires as Sydney - and retailers price per network, not per city. Every plan in the table above costs exactly the same in Newcastle as it does in Sydney.
How many Newcastle homes have solar? ⌄
Our Clean Energy Regulator data counts 63,238 rooftop solar systems across Newcastle, Lake Macquarie and lower Hunter postcodes - roughly 0% of homes. Every kWh generated on the roof avoids the usage rates in the table, which is a bigger saving than any plan switch.
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 Newcastle? ⌄
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.
