Cheapest Electricity Plans in New South Wales by Network

Finding the cheapest electricity in New South Wales

NSW has three electricity networks. Ausgrid covers Sydney, the Central Coast and the Hunter. Endeavour Energy covers Western Sydney, the Blue Mountains and the Illawarra. Essential Energy covers the rest of the state.

Prices differ more between networks than most people expect, because each network sets its own charges and retailers pass them on. Regional homes in the Essential Energy area pay the most. The Default Market Offer, set by the AER, is the reference price retailers must compare their plans against.

All the plans ranked here are flat-rate plans that any household in the network can sign up for. If you have a smart meter and can shift usage to the middle of the day, look at time-of-use and Solar Sharer plans too.

How to get the best price

1. 01

   Find your network

   It is on your bill as the distributor. Prices differ a lot between networks.

2. 02

   Use a year of your own usage

   Add up the kWh on four quarterly bills, or download your smart meter data.

3. 03

   Check the full plan

   Look at the supply charge, usage rate, feed-in tariff and any conditions on the fact sheet.

4. 04

   Compare on the government site

   Energy Made Easy lists every generally available plan and prices it on your usage.

5. 05

   Ask your current retailer first

   Your bill's better offer message may already point to a cheaper plan.

Wholesale-linked retailers such as Amber Electric and Flow Power are not ranked because their prices follow the wholesale market, so their published rates are only estimates.

How these prices were worked out

Every price on this page comes from the plans retailers publish to the AER's Energy Made Easy data under the Consumer Data Right, as at 14 October 2026. We price flat-rate (single rate) plans that any household in the area can sign up for, at 2,500, 4,000, 6,500 kWh a year, including GST, the daily supply charge and guaranteed discounts. Conditional discounts, such as for paying on time, are left out. Plans limited to members, existing customers or homes with particular equipment are excluded. Retailers with wholesale-linked prices are listed separately, not ranked.

Prices change, sometimes weekly. Always confirm the current price on the retailer's plan fact sheet or a government comparison site before you switch. Our switching guide covers the steps.
