WA solar export rates (DEBS)

Unlike east-coast states where you can shop around for the best feed-in tariff, WA rates are set by the state government. Here are the current schemes and rates.

You can't switch providers in WA. Synergy is the only retailer for the SWIS grid (Perth and surrounds). Horizon Power serves regional areas. Your rate is determined by which scheme you're on, not which retailer you choose.

  • Synergy (DEBS)

    Peak rate
    10c/kWh
    Off-peak rate
    2c/kWh

    Peak hours: 3pm to 9pm. South West Interconnected System (Perth metro and surrounds). Systems of 5kW or less; buyback required for the first 50kWh a day.

  • Synergy (REBS)

    Peak rate
    7.135c/kWh
    Off-peak rate
    7.135c/kWh

    Peak hours: Flat rate (all hours). Closed to new applicants. Grandfathered for existing customers.

  • Horizon Power (DEBS)

    Peak rate
    10c/kWh
    Off-peak rate
    3c/kWh

    Peak hours: 3pm to 9pm. Low-cost towns such as Broome, Karratha and Esperance. Medium and high-cost towns pay more.

How feed-in tariffs work in Western Australia

Western Australia operates outside the National Electricity Market. Unlike east-coast states where retailers compete on feed-in tariff rates, WA has a government-set buyback scheme called DEBS (Distributed Energy Buyback Scheme) for systems of 5kW or less. Synergy, the state-owned retailer serving the South West Interconnected System (SWIS), pays a time-varying rate: 10c/kWh during peak hours (3pm to 9pm) and 2c/kWh at all other times, and retailers only have to buy back the first 50kWh a day. Horizon Power serves regional and remote WA, with rates that depend on the town. The older REBS (Renewable Energy Buyback Scheme) pays a flat 7.135c/kWh but is closed to new applicants.

  • Government-set rates through DEBS, not retailer-determined like east-coast states
  • Time-varying: 10c/kWh peak (3pm to 9pm) and 2c/kWh off-peak under DEBS

  • Retailers only have to buy back the first 50 kWh exported a day under DEBS

Tips for maximising your solar export income in WA

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

  1. Time your exports for peak

    Under DEBS, you earn 5 times more exporting between 3pm and 9pm (10c) than during the day (2c). A battery that stores solar and exports during peak hours maximises your return.

  2. A battery matters most in WA

    At just 2c/kWh off-peak export, daytime solar is worth almost nothing to the grid. A battery lets you self-consume or export during peak for 10c.

  3. Maximise self-consumption

    WA electricity costs around 30c/kWh. Using your own solar saves 15x more than exporting at the 2c off-peak rate. Run appliances during solar hours.

  4. Know the 50 kWh daily limit

    Retailers only have to buy back the first 50kWh you export each day under DEBS, which covers systems of 5kW or less.

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

Even the best flat WA feed-in tariff of 10c/kWh is well below the average Western Australia electricity rate of 30c/kWh. Self-consuming your solar saves you 20c/kWh more than exporting it.

Western Australia feed-in tariff FAQ

What is the solar feed-in tariff in Western Australia?
WA uses the Distributed Energy Buyback Scheme (DEBS) for systems of 5kW or less. Synergy pays 10c/kWh during peak hours (3pm to 9pm) and 2c/kWh at all other times, and only has to buy back the first 50kWh a day. Horizon Power pays 10c peak and 3c off-peak in its low-cost towns, and more in some remote towns. These rates are set by the state government, not by retailers (Synergy and Horizon Power pricing schedules, 1 July 2026).
What is the difference between DEBS and REBS in WA?
DEBS (Distributed Energy Buyback Scheme) is the current scheme with time-varying rates of 10c peak and 2c off-peak. REBS (Renewable Energy Buyback Scheme) was the older scheme paying a flat 7.135c/kWh. REBS is closed to new applicants but existing customers can stay on it. If you installed solar after August 2020, you are on DEBS.
Why is WA different from other states?
Western Australia is not connected to the National Electricity Market (NEM) that covers the east coast. WA has its own grid (the South West Interconnected System) and its own state-owned retailer (Synergy). Because there is no retail competition, the government sets feed-in tariff rates directly rather than letting the market determine them.
Should I get a battery in Western Australia?
A battery makes strong financial sense in WA. The off-peak export rate of just 2c/kWh means most of your daytime solar exports are nearly worthless. A battery lets you store that energy and either use it in the evening (saving ~30c/kWh) or export during the 3-9pm peak window (earning 10c/kWh). Either way, a battery turns 2c solar into 10 to 30c of value.
What is the 50kWh daily export limit?
Under DEBS, retailers only have to buy back the first 50kWh you export each day (Energy Policy WA). DEBS covers systems of 5kW or less, which rarely export that much in a day.

Stop exporting for 10c. Start saving 30c.

A home battery lets you store your solar and use it when electricity prices are highest. See what rebates you qualify for.
