How feed-in tariffs work in South Australia

South Australia's feed-in tariff market is fully deregulated: retailers set their own rates with no government-mandated minimum. SA has a single electricity distribution network (SA Power Networks), which simplifies things compared to multi-network states. SA historically had some of Australia's highest electricity prices, which initially supported higher FIT rates, but as solar penetration has grown, export rates have declined alongside falling wholesale prices.

Regulated by
None (fully deregulated)
South Australia has no regulated minimum feed-in tariff. With only one distribution network (SA Power Networks), plan availability is consistent across the state.
  • Fully deregulated: no minimum FIT rate
  • Single distribution network: SA Power Networks (statewide)
  • SA leads in renewable energy: solar and wind regularly meet 100% of state demand
  • SA has experienced negative wholesale prices during sunny days, putting pressure on FIT rates

Tips for maximising your solar export income in SA

Getting the most from your solar system in South Australia isn't just about finding the highest feed-in tariff.

  1. Compare frequently

    SA retailers compete aggressively on FIT rates. Switching can make a meaningful difference to your export income.

  2. A battery matters most in SA

    With some of Australia's highest electricity prices and lowest FIT rates, the self-consumption gap in SA is among the widest.

  3. Consider TOU tariffs

    SA has significant peak/off-peak price spreads. A battery that stores solar and discharges during the 4pm to 8pm peak saves the most.

  4. Pair solar with an EV

    Charging an EV with your solar during the day offsets expensive petrol and avoids exporting at low FIT rates.

With FiT rates this low, is exporting still worth it?

Even the best SA feed-in tariff of 12c/kWh is well below the average South Australia electricity rate of 36c/kWh. Self-consuming your solar saves you 24c/kWh more than exporting it.

South Australia feed-in tariff FAQ

What is the best solar feed-in tariff in South Australia?
SA FIT rates are fully market-driven and change frequently. Check the retailer rankings above for the current best rate. Rates typically range from 3 to 10c/kWh.
Why are SA feed-in tariffs dropping?
South Australia has the highest per-capita rooftop solar in the country. During sunny days, so much solar is exported that wholesale prices go negative. Retailers can't sustain high FIT rates when the power they're buying from you is worth less than zero on the wholesale market.
Is a battery worth it in South Australia?
Absolutely. SA has the widest gap between FIT rates and electricity prices in Australia. Self-consuming your solar via a battery can save 5 to 8 times more per kWh than exporting it. SA also has strong VPP programs that pay battery owners for grid support.
How do VPP programs work in South Australia?
SA has excellent VPP opportunities due to frequent grid stress events. Programs like Origin Loop, AGL VPP, and Simply Energy VPP pay 12 to 25c/kWh during events. The SA Government's VPP program has also offered free batteries to eligible homes. SA is one of the best states for VPP earnings in Australia.

Stop exporting for 12c. Start saving 36c.
