Important Message To Ergon Customers – July 1st Tariff 11 Changes

  • 4th July, 2025

We just wanted to let you know about an important change that took effect on July 1st 2025.

All Ergon Energy residential customers have now been AUTOMATICALLY switched from the flat-rate Tariff 11 to a Time of Use tariff (Tariff 12D).

What does this mean for you?

Instead of paying a consistent $0.33 per kWh, your electricity will now be charged at different rates depending on the time of day.

Here’s the concern:
Most households use the bulk of their electricity between 4pm and 9pm – when we get home, cook dinner, take showers, run the air-conditioning, and unwind in front of the TV.

Under the new tariff, usage during this peak period will now be charged at a much higher rate – $0.457 per kWh. That’s a significant increase.

Tariff 12D ⬇️

A time of use tariff designed to help you save during the day and nighttime off-peak periods. All rates include GST.

Peak Period: 4pm to 9pm daily (45.7 cents) (instead of Tariff 11, 33 cents)

Night (shoulder) Period: 9pm to 11am daily

Day (off peak) Period: 11am to 4pm daily

From 1 July 2025 – Current Rate COST
Night (shoulder) Usage per kWh $0.28035
Peak Usage per kWh $0.45712
Day (off peak) Usage per kWh $0.22680
Supply Charge per day $1.48834

There has never been a better time to take advantage of the new Government Battery Rebate – offering up to $17,500 for eligible households.

Why is this important?

With electricity rates now surging during the peak hours of 4pm–9pm, having a home battery allows you to store solar energy during the day and use it when power is most expensive. This can significantly reduce your bills and protect you from rising energy costs.

When you get a Home Battery you can then Switch to ⬇️

Solar Soaker (Tariff 12E)

A time of use tariff designed to help you save during the day and nighttime off-peak periods.  All rates include GST.

Peak Period: 4pm to 9pm daily

Night (shoulder) Period: 9pm to 11am daily

Day (off peak) Period: 11am to 4pm daily

From 1 July 2025 – Current Rate COST
Night (shoulder) Usage per kWh $0.26375
Peak Usage per kWh (Battery eliminates this) $0.57363
Day (off peak) Usage per kWh $0.07724
Supply Charge per day $1.48834

Please let us know if you have any questions we can help you with.
