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.

info
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 - 9pm

South West Interconnected System (Perth metro and surrounds). 50kWh daily export cap.

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)

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). Synergy, the state-owned retailer serving the South West Interconnected System (SWIS), pays a time-varying rate: 10c/kWh during peak hours (3pm-9pm) and 2c/kWh at all other times, with a 50kWh daily export cap. Horizon Power serves regional and remote WA with slightly different rates. The older REBS (Renewable Energy Buyback Scheme) paid a flat 7.135c/kWh but is closed to new applicants.

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.

schedule

Time your exports for peak

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

Battery is essential 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.

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.

warning

Watch the 50kWh daily cap

DEBS caps paid exports at 50kWh per day. If you have a large system (10kW+), you may hit this limit on sunny days. A battery helps capture the excess.

Why FiT rates are declining

With FiT Rates This Low, Is Exporting Still Worth It?

Even the best 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?expand_more
WA uses the Distributed Energy Buyback Scheme (DEBS). Synergy pays 10c/kWh during peak hours (3pm-9pm) and 2c/kWh at all other times. There is a 50kWh daily export cap. Horizon Power pays 10c peak and 3c off-peak in standard towns. These rates are set by the state government, not by retailers.
What is the difference between DEBS and REBS in WA?expand_more
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?expand_more
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?expand_more
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 10-30c value.
What is the 50kWh daily export cap?expand_more
Under DEBS, Synergy only pays for the first 50kWh of energy you export per day. Any exports beyond 50kWh are sent to the grid for free. For a typical 6.6kW system, this cap rarely applies. But larger systems (10kW+) on long sunny days can exceed it. A battery helps by storing excess rather than exporting unpaid energy.

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.
