How do we calculate the cheapest electricity and gas plans in Sydney, NSW
Our rates table (near the top of the page) instantly calculates the annual estimated price (in real time) of each Sydney electricity and gas plan in our database. These are the factors that influence the estimated cost:
- Usage rates: The rate paid (in c) for every kWh of electricity or megajoule (MJ) of gas used.
- Supply rates: Fixed daily cost paid to maintain a connection with the grid (for electricity) and/or the gas mains.
- Estimated annual usage: The estimated annual energy usage of a residential customer living within the Ausgrid network (for electricity) and the Jemena Gas network (for gas). This figure currently sits at 3,900 kWh for electricity customers on a single-rate tariff and 18,200 MJ for gas customers.
- Reference price: The NSW reference price for electricity, also known as the default market offer (DMO), is a price cap set by the Australian Energy Regulator (AER), protecting customers from overpaying for their electricity. Currently, the reference price in Sydney on the Ausgrid network sits at $1,965/year. On 1 July 2026, the reference price will decrease to $1,889. The DMO is also set to introduce reference prices for time of use (ToU) tariffs and a new solar sharer offer, which offers three hours of free electricity between 11am and 2pm.
Guaranteed or conditional discounts are excluded from each plan’s estimated cost. Any ongoing discounts are listed on a blue banner found under each electricity or gas plan.
You can click on the toggle at the top of the rates table to switch between ‘electricity’ and ‘gas’ results.
How to use the NSW electricity and gas plans rates table
By default, our rates table will show our database's plans for NSW 2000, organising the results based on the following filters:
- Lowest to highest estimated annual price
- Single-rate or flat-rate tariffs
- No solar panels installed (only for electricity plans).
You can freely use the built-in filters below to fine-tune the results you want to see:
- Single rate, ToU or controlled load tariffs (for electricity only)
- Monthly, quarterly or estimated cost.
You can further sort the results based on the following options:
- Estimated price (ascending or descending)
- Provider names alphabetically (ascending or descending)
- Feature rating (ascending to descending)
- Reference price comparison (for electricity only).

What to consider with the cheapest electricity and gas plans in Sydney, NSW
Bundled electricity and gas discounts
A provider who sells electricity and gas plans may entice customers with a bundling discount. However, signing up for an electricity and gas plan from two separate providers could be cheaper. Run the numbers for both options first before choosing the cheaper one.
Your electricity and gas use
When you use the most electricity
- If you use more electricity during off-peak periods, a ToU tariff or demand tariff will save you more, as it charges lower usage rates during those hours.
- If you use more electricity during peak periods, a single-rate tariff is cheaper, as it charges you lower usage rates during those hours.
- If you have a power-hungry appliance, a controlled load tariff will save you more.
How much electricity or gas you use
- If you don’t use a lot of electricity, a plan with lower supply rates will save you more in the long term, as it forms the bulk of your power bill.
- If you don’t use much gas, a flat rate tariff is cheaper than a block rate tariff, where low volume use is charged at a lower rate.
If you’d like to estimate your potential savings from switching to the cheapest electricity plan on our database, you can visit our electricity bill calculator page. Keep in mind that you'll need to have your latest power bill on hand to get a working calculation.
Contract length and expiries
With energy plans, there are two types of contracts — ongoing and contracts with a fixed contract length.
Ongoing plans don’t have an expiry date, permitting you to switch providers or plans at any time.
In comparison, plans with a fixed contract length have a set expiry. Exiting early will result in penalty fees.
Once your plan passes that date, you’ll be automatically moved onto your provider’s standing offer (for electricity) or standing contract (for gas)
Standing offers and contracts in NSW adhere to that state’s reference price, which usually reflects the highest price retailers are willing to charge. They also don’t offer any value-added features (e.g. bill credits, guaranteed discounts).
If you’re currently on a standing offer or contract, that means you’re set to pay hundreds of dollars more than you should annually.
You can determine a plan’s contract length under the ‘contract details’ section on its BPID, which is accessible through the ‘basic plan information’ prompt on our journey’s results page or the ‘plan details’ prompt under each plan.
If your preferred plan has a fixed contract length, we strongly encourage you to add a calendar reminder to switch energy plans days before it is set to expire.
Variable vs fixed rates
The majority of energy plans are variable-rate plans — that means they can change, irrespective of whether your plan is ongoing or has a set expiry. However, your retailer must notify you in writing at least five business days before any scheduled changes.
If the cheapest energy plans in Sydney are variable rate plans, their annual estimated costs may change frequently. It’s important to keep track of all written correspondence (e.g. emails) from your provider.
Some providers offer fixed-rate plans with rates frozen over a fixed contract length (e.g. 12 months). However, fixed-rate plans are not common.
An energy plan’s rate type can be found under the ‘Billing and price details’ section in its BPID.
Hidden fees
Before switching to another plan, be aware of any hidden fees (e.g. disconnection/connection and exit fees) on your current plan’s BPID.
