SAPN Two-Way Tariff (RESELE)

SA Power Networks has introduced its own two-way tariff to incentivise energy behaviours that are good for the grid and the environment.

What's on offer

• 12.25c/kWh export credit during peak periods daily from November to March (5pm–9pm)
• Cheaper solar sponge (2.84c/kWh export charge above free threshold) from 10am–4pm daily
• 9kWh daily free export allowance during the solar sponge window, which carries over if unused within a billing period
• Shoulder period (midnight–10am and 4pm–5pm) at 9.49c/kWh usage
• Peak usage (5pm–9pm) at 31.98c/kWh
• Tariff available from 1 July 2025

The times at which the tariffs will apply (excluding seasonal changes such as the export reward):

Who can make the most of this tariff

• Battery Requirements: Due to the export bonus and the peak consumption charges both falling between 5pm–9pm, your battery needs to be able to power your home until 9pm every night to make the most of this tariff.
• Make sure your battery is fully charged by 5pm (we'll help with SmartShift). To ensure you can sell excess energy for a bonus FiT and avoid peak charges throughout the peak period, ideally it would still have 30% state of charge by the end of the peak period at 9pm. This is because SmartShift can only control your battery if it has at least 25% state of charge.

Who is not best suited to this tariff

• Anyone whose battery can't usually power their home through to 9pm and is a heavy user of grid energy during the peak period.

Things to consider before joining

While there are significant benefits on offer for the right customers, given the charges in the peak pricing period, the one year commitment, and the fact there's NOT a no-worse-off guarantee, we recommend that Amber customers consider carefully if they're well suited to this tariff before joining.

• Peak Window Pricing of 31.98c/kWh (added to the wholesale rate): The usage pricing during the peak window is higher, but it's only for a 4-hour period (5pm–9pm). For comparison, the standard Residential Time of Use (RTOU) tariff has a much longer 12-hour peak window.
• Between 10am–4pm there is a 1c/kWh charge for exporting more than 9kWh of solar, but if you have a SmartShift-compatible hybrid battery/inverter setup, we'll include it in the feed-in tariff price and SmartShift will optimise around this charge and curtail your solar like we already do.
• Provided you're not a heavy user of energy during the peak period (5–9pm), you can do well on this tariff even without significant exports during the peak period, thanks to the low shoulder and solar sponge usage rates on offer.
• One year commitment: SAPN will not switch your tariff again for a year once you've been switched onto this tariff.
• No guarantee: There's NOT a no-worse-off guarantee like there is with some two-way tariffs (e.g. Ausgrid).

How to join this tariff

We will reach out to you via email with an opt-in form if you're part of the SmartShift™ program and we suspect you may be better off on this tariff.

If you want to leave Amber

As the RESELE tariff is a customer choice tariff, it may not be available at all retailers. If you are planning to move retailers, you will need to be moved back to the SAPN Residential Time of Use (RTOU) tariff. Please email info@amber.com.au and write: 'Please update my tariff to RTOU' in order to move over.
