In July 2025, the Australian federal government will officially launch the Cheaper Home Batteries Subsidy Program. All grid-connected energy storage systems installed under this initiative must be capable of participating in virtual power plants (VPPs). This policy aims to deepen the integration of distributed home battery backup systems with the national grid.
The Australian Energy Market Operator (AEMO) envisions millions of households collaborating with the grid through rooftop solar and home solar battery storage systems. Such synergy would provide additional services, create a bidirectional energy ecosystem, improve renewable energy utilization, and enhance grid security and cost-effectiveness.
1. Current State of Australia’s Home ESS Market
According to the 2024 Australian Battery Market Report by SunWiz:
⭐ By 2024, only 56MW of VPP capacity (linked to ~11,200 households) was registered with AEMO.
⭐ South Australia dominates with 51MW, largely from Tesla's VPP pilot (launched in 2019). Despite targeting 50,000 homes, only 7,000 participated. Even in this VPP-mature region, just 10% of new home battery backup power supply adopters joined VPPs in 2024, while NSW saw 4-10% participation.
⭐Contrastingly, Australia's total household solar batteries for home capacity reached 3,600MWh in 2024, with 72,500 new systems installed. Most households opted out of VPPs.
A survey by onestepoffthegrid reveals key barriers to VPP adoption:
- ▲ Unclear Benefits: Limited financial returns and complex calculations make VPP value hard to assess.
- ▲ Control Concerns: Homeowners prioritize energy autonomy over grid cooperation. After investing in home storage battery systems, many resist handing control to utilities.
- ▲ Complex Programs: VPP rules and rewards vary widely, raising decision-making costs.
2. Emerging Models in VPP Operations
VPP providers are shifting from "pre-sale discounts" to "bring-your-own-battery" strategies. Amber Electric's SmartShift™ program exemplifies this trend, gaining strong traction.
(SmartShift™ is an advanced battery optimization tool that manages home energy storage battery charging/discharging based on real-time electricity prices, maximizing savings and renewable energy use.)
Key differences from traditional VPPs:
- ✔ Full Revenue Transparency: SmartShift returns 100% of wholesale market earnings to users, charging only a $22/month fee.
- ✔ User Control: Offers granular settings (charge/discharge/battery protection) and allows users to disable SmartShift anytime.
- ✔ Household-Centric Focus: Triggers battery backup for home appliances at the individual household level, tailoring decisions rather than bulk-managing users.
The Road Ahead for VPPs
VPP success depends on policy incentives and trust-building as a critical pathway for modernizing power grids. Australia's experience highlights the role of user behavior in energy transitions. Rapid growth in home battery storage systems provides a foundation, but scaling VPP adoption requires design, innovative products (like battery backup for home solutions), and user education. If these align, VPPs could reach their tipping point soon.
