Solar Feed-In Tariff Rates in South Australia (2026)
South Australia has the highest rate of household solar adoption in Australia, with over 40% of homes now equipped with rooftop solar panels. The Essential Services Commission of South Australia (ESCOSA) oversees the energy market, including feed-in tariff arrangements. With so much solar on the grid, feed-in tariff rates have moderated in recent years, making it especially important to compare plans.

Typical rate range
Feed-in tariff rates in SA are typically 5–10 c/kWh, depending on your energy retailer and plan.
Retailer feed-in tariff rates in South Australia typically range from 5–10 c/kWh. With the state's very high solar penetration, wholesale electricity prices during sunny periods have dropped significantly, which has put downward pressure on feed-in rates. Some retailers offer premium rates on solar-specific plans.
How feed-in tariffs work in SA
- •South Australia uses net metering. Solar energy powers your home first, and only the surplus exported to the grid earns the feed-in tariff.
- •ESCOSA (Essential Services Commission of South Australia) regulates the energy retail market and publishes guidance on feed-in tariff arrangements. However, there is no mandated minimum FiT rate — retailers set their own rates.
- •SA Power Networks is the sole electricity distributor in South Australia. Your distributor does not affect your feed-in tariff rate, which is set by your energy retailer.
How to get the best feed-in tariff in SA
- •With feed-in rates relatively low, maximising self-consumption of your solar generation is often more valuable than exporting to the grid.
- •Battery storage is increasingly popular in SA. Storing solar energy for evening use avoids importing electricity at higher usage rates.
- •Compare plans based on total cost, not just the feed-in tariff. A plan with a lower FiT but cheaper usage rates may save you more overall.
- •Consider time-of-use plans. SA electricity prices spike during evening peak periods — using stored solar or shifting usage to daytime hours can significantly reduce your bill.

Frequently asked questions
What is the current solar feed-in tariff in South Australia?
Feed-in tariff rates in South Australia typically range from 5–10 c/kWh, depending on the energy retailer and plan. There is no regulated minimum rate.
Why are SA feed-in tariff rates lower than they used to be?
South Australia's very high solar penetration means the grid is often flooded with solar energy during the day, pushing wholesale prices down. This has reduced the value retailers place on exported solar.
Is battery storage worth it in South Australia?
Battery storage can be very effective in SA. With relatively low feed-in rates and high evening usage charges, storing solar energy for self-consumption typically delivers a better return than exporting it.
Can I switch retailers to get a better feed-in tariff in SA?
Yes. South Australia has a competitive retail electricity market. You can switch retailers at any time to access a different feed-in tariff rate and usage charges.
