How does Alinta Energy compare with other WA gas retailers?
Every WA retailer delivers through the same ATCO network, so plans are directly comparable. The table lists each retailer in order of the lowest usage rate in its recorded plans, with Alinta Energy marked. Usage rate alone does not decide annual cost, because supply charges and discounts also count.
| Retailer | Lowest usage rate | Supply charge | Plans |
|---|---|---|---|
| Origin Energy | 2.78c/MJ | 26.83c/day | 2 |
| Alinta Energy (this page) | 5.29c/MJ | 54.79c/day | 2 |
| Kleenheat | 5.29c/MJ | 54.79c/day | 2 |
| AGL | 5.32c/MJ | 53.35c/day | 1 |
A plan with the lowest per-megajoule rate but a high daily supply charge can still cost a low-use home more over a year. No retailer is cheapest for every home: the cheapest plan depends on your usage. The full comparison lines up every plan by estimated annual cost once you enter your own usage.
What does Alinta Energy charge for gas?
Every WA gas plan is built from two numbers: a fixed daily supply charge you pay whether you burn gas or not, and a usage rate for each megajoule (MJ, the unit gas is measured in) you use. Both are quoted including GST. BillWise's cards below set Alinta Energy's recorded range against the market range.
5.29c to 5.29c per megajoule
Alinta Energy's first-block usage rates, against a market range of 2.78c to 5.32c per MJ across every recorded WA plan.
54.79c to 54.79c per day
Charged whether an appliance runs or not. The market range is 25.56c to 54.79c per day, or roughly $93 to $200 a year before a single megajoule is burned.
Retailers often quote gas in units rather than megajoules. One unit is 3.6 MJ, so divide a cents-per-unit rate by 3.6 before setting it against the figures above. Every rate here is recorded from published retailer pricing; any rate we cannot independently verify is withheld from this comparison rather than shown. Updated September 2026.
