The ACT’s solar battery storage incentive program

The ACT government’s Next Generation Energy Storage (Next Gen) program, initially launched in 2016, is one of the most ambitious battery storage incentive schemes in Australia, aiming to subsidise the installation of batteries for roughly 5,000 homes and small businesses.

The program has $25 million in funding and is targetting the install of 36MW in capacity. A mid-term review of the program in March 2019 showed that they had subsidised over 600 batteries and were accepting over 200 applications per year.


How the ACT battery rebate (Next Gen) works

The Next Gen scheme currently offers a rebate of 50% of the battery price up to a maximum of $3,500.

To give you an idea, the below table details some of the more popular batteries under the scheme and the applicable rebate.

Usable Capacity Continuous Output Rebate
Tesla Powerwall 2 13.5 kWh 5 kW $3,500
LG RESU10 8.8 kWh 5 kW $3,500
Alpha-ESS SMILE T-10 15kWh 10 kW $3,500
BYD B-Box LVS 3kWh 3.33 kW ~$2,000

Like the federal solar rebate (STC scheme) the installer accesses the rebate on your behalf and is able to offer a point of sale price reduction. You can look at battery offers from some of the pre-qualified installers in the scheme through Solar Choice’s comparison portal.

Eligibility for ACT’s battery rebate

To receive the rebate you must meet the following 4 criteria:

  1. In the ACT area including Hall, Tharwa and Oaks
  2. New battery system must be coupled with solar panels
  3. Be connected to the grid (off-grid installations are not eligible)
  4. A new system that has not already received a rebate from the Next Gen scheme


How the ACT selects pre-qualifed installers

ACT-renewable-energy-auction-nextgenThe NextGen program is an auction-based incentive scheme, where different entities ‘bid in’ under a government-run tender process for the right to offer the incentive to their customers. The eligible systems and providers have all been vetted by the government for quality, reliability, reputation and ability to deliver on promises.

You can view live battery pricing on Solar Choice’s website from installers who are pre-qualified under the Next Gen Scheme.

How does this change ROI for a battery system in the ACT?

Solar Choice has developed and published an advanced calculator to help Australians calculate their savings, payback period and ROI for their own circumstances. Inputting into this calculator a likely household scenario for the ACT with an electricity rate of 20c per kWh and an average daily usage of 30kWh we have calculated the below scenarios:

Before ACT Rebate After ACT Rebate
Solar Size Battery Usable Capacity Savings Estimated Cost Payback Period Estimated Cost Payback Period
6.6 kWh Tesla Powerwall 2 13.5 kWh $1,308 p.a. $18,625 12.7 years $15,125 10.6 years
6.6 kWh LG Chem RESU6 5.9 kWh $1,437 p.a. $11,500 8.4 years $8,035 6.3 years


Other Benefits of a Battery Storage System

Reducing your carbon footprint

By storing and using surplus solar energy, households can get close to using 100% of their power from renewable sources. Simple grid-connected solar (only) systems still rely on 50%+ of their electricity coming from the grid. Reducing demand for grid power will accellerate the energy transition and reduce the need for Australia’s many coal-fired power plants.

Backup power in a blackout

Although the ACT electricity network has been fairly stable, the ability for households to keep the lights and fridge on during a blackout can be an important factor when deciding whether to invest in a solar battery. Products such as the LG Chem or Tesla Powerwall have an inbuilt battery inverter which enables them to charge during a blackout, and effectively can provide backup power for days or weeks if needed.

Additional income with Reposit

Canberra is home to battery management system developer Reposit Power, whose software platform allows battery system owners to sell their stored energy into the grid at a premium during high wholesale spot price events. Although these price events are somewhat rare (a few times a year), it can increase the savings you will make from your battery and improve the payback period.
