WA Battery Rebate Scheme
WA Battery Rebate Scheme
To apply for the WA battery rebate you will need to apply to the scheme administrator. Once approved an application will need to be submitted to Synergy and then to Western Power for connection to the network.
If you are on a shared connection, the maximum capacity for the connection point is 30kVA. You can apply for a Multi residential exemption. Please contact 13 10 87 for more information.
You can email the Embedded Generation team.
Most applications receive pre-liminary ‘approval to install’ from Western Power within 15 business days.
Your current restrictions will remain in place until you upgrade the system. A new application will be needed at that time.
Yes, if you're applying for a rebate or installing AC-coupled batteries, an application is required, and your installer must submit a Notice of Completion to Building and Energy.
If you're adding DC-coupled storage without modifying inverters, an application may not be required, but check first.
If you’re changing or upgrading your inverter to support more panels, yes, you’ll need to apply for a system upgrade.
This can be done by you or your installer.
No. Emergency Solar Management (ESM) is a system that helps protect the network during very low energy demand by curbing solar exports.
A VPP, by contrast, actively manages energy export across multiple systems to match local network demand and conditions throughout the day.
A Virtual Power Plant (VPP) connects and coordinates household solar panels, batteries and other energy systems so they operate like a traditional power station. This allows energy to be shared with the network when it’s needed, supporting system stability and creating opportunities for you to earn additional value from your equipment.

Solar battery system
A generation limit sets the maximum amount of power your solar system can generate safety and securely. This could involve multiple inverters acting together as a single system, or a single larger inverter being de-rated to meet connection constraints.
For example, a 10kVA inverter with a 5KW generation limit would not be able to generate more than 5KW.
Under the Western Australian Technical Rules and the Basic Embedded Generator (EG) Connection Technical Requirements inverter capacity is assessed based on the total rated capacity of all inverters connected at the site, regardless of whether the system is exporting power. There are several reasons for this:
1. No offtake agreement with your Energy Retailer
If you do not have an offtake agreement with your Energy Retailer the inverter must be export limited to 1.5kW
2. Technical capability to export
Even if configured for zero export, inverters can technically still export power, which must be considered in network planning.
3. Local and broader network constraints
Larger inverter capacities can affect voltage levels, harmonics, and flicker, impacting power quality for all customers. These technical limits are in place to maintain compliance with Australian power quality standards.
4. Fair and efficient access
Standard limits for Basic EG systems help ensure fair access to network capacity for all customers. They also reduce the need for complex, case-by-case technical assessments, making the connection process simpler and faster.
5. Regulatory and safety compliance
We assess systems based on maximum potential impact, including safety measures like Emergency Solar Management, protection coordination, and voltage rise limits, which are all based on inverter capacity, not just export settings.
An export limit sets the maximum amount of electricity your solar system can export to the network. This helps maintain network stability, security, and safety for you and the wider community.
Yes. Advanced meters are installed in all new homes. In existing homes, we install an advanced meter when the old one reaches the end of its service life, or if your retailer requests one to support a new service, such as a new battery.
We’re working towards expand communication coverage across the electricity network. You can visit Advanced Metering FAQs for further details.
If your strata has reached its limit, you may still be able to install a battery system by applying for a multi-residential exemption or upgrading your connection point. Please contact 13 10 87 for more information.
Your connection point has a fixed capacity. If it’s shared with other customers, multiple systems could exceed that capacity, which can make it unsafe and unreliable.
Shared connections need to be managed so everyone has access to a safe, secure electricity supply—and the opportunity to benefit from renewable energy.
Capacity limits are set within the Basic EG Connection Technical Requirements to ensure Distributed Energy Resources (DER) is safely and reliably connected to Western Powers network. Your retailer is the best point of contact for system size questions and options available to you.
They’ll also consider whether there’s enough suitable roof space for a larger system.
For system-specific advice, it’s best to speak to a solar provider.
They’ll consider your lifestyle, current and future energy needs, and preferences before suggesting the right solar and battery system for you.
We evaluate the system’s impact on the network to ensure it can be supported.
