Trial compliant devices
About this list
This list is designed to help A Simple Shift endorsed installers and their customers understand which flexibility systems currently meet the requirements for participation in the A Simple Shift flexibility trial. This list will be updated regularly as additional compliant systems are assessed and approved.Trial incentives
To support the installation of compliant flexibility technology for this trial, a limited number of households may be able to access the following incentives:
- $4,000 towards the installation of a residential battery. The battery must have capacity greater than 9kWh. Households may choose to install a larger battery, but the incentive amount will remain the same.
- Up to $1,500 towards the installation of a home energy management system (HEMS). The HEMS must be connected to at least one household device or load, such as a heat pump, air conditioning unit, hot water cylinder or other smart appliance.
