Solar Feed-In Tariff Rates in Western Australia (2026)
Western Australia operates outside the National Electricity Market and has a different structure for solar feed-in tariffs. Most residential solar customers in the South West Interconnected System (SWIS) are on Synergy's Renewable Energy Buyback Scheme (REBS). Unlike eastern states where you can shop between multiple retailers, most WA households purchase electricity from Synergy.
Current solar feed-in tariff rates in WA
Typical rate range
Feed-in tariff rates in WA are typically ~10 c/kWh, depending on your energy retailer and plan.
The Synergy Renewable Energy Buyback Scheme (REBS) currently pays approximately 10 c/kWh for residential solar exports. This rate applies to systems up to 5 kW in size. Larger systems may be eligible for different arrangements. The REBS rate is set by Synergy and reviewed periodically.
How feed-in tariffs work in WA
- •WA uses net metering under the REBS arrangement. Your solar system powers your home first, and only surplus electricity exported to the grid earns the buyback credit.
- •Synergy is the dominant energy retailer in the SWIS (South West Interconnected System), which covers Perth and the surrounding region. Most residential customers are on Synergy's standard plans.
- •Western Power manages the electricity distribution network in the SWIS. Like other states, your distributor does not affect your feed-in tariff rate.
How to get the best feed-in tariff in WA
- •Check whether your system size qualifies for the standard REBS rate. Systems larger than 5 kW may have different export arrangements.
- •Since most WA households are on Synergy, focus on choosing the right Synergy plan for your usage patterns rather than switching between retailers.
- •Battery storage is growing in popularity in WA. With a REBS rate of around 10 c/kWh and usage rates considerably higher, storing solar for self-consumption can be more cost-effective than exporting.
- •Consider whether a time-of-use Synergy plan aligns better with your solar generation and household usage patterns.
