How 1st Energy compares

1st Energy’s cheapest plan beats the regulated benchmark on 10 of the 11 networks that have one. The biggest margin is on Essential Energy: 20.1% below the Default Market Offer.

It is among the five cheapest retailers on Ausgrid (4th of 22), Endeavour Energy (4th of 24), Essential Energy (2nd of 23), CitiPower (2nd of 24), Powercor (2nd of 25), Jemena (1st of 24), United Energy (2nd of 26), AusNet Services (2nd of 25), Energex (5th of 20) and SA Power Networks (3rd of 21). It is not in the dearest third on any network.

The widest gap to the market is on SA Power Networks, where 1st Energy’s cheapest plan costs $1,337 a year more than Radian’s at $2,892.

On United Energy, its cheapest plan has a higher daily charge (129.4c against 121.0c) and a lower usage rate (21.5c against 21.7c a kWh), so it becomes the cheaper of the two above about 15,000 kWh a year. That is why a review costs every plan against your own bills and meter data, not a reference usage.
