Australian households with solar and battery storage are reaping significant financial rewards, with potential annual savings reaching up to $1,093. However, this burgeoning sector is simultaneously experiencing a sharp increase in consumer grievances, as highlighted in the Australian Competition and Consumer Commission’s (ACCC) latest Electricity Market Inquiry report, released on 9 July 2026. The report reveals a concerning 107% surge in consumer complaints related to home batteries and Virtual Power Plants (VPPs) in the first quarter of 2026, prompting calls for urgent consumer protection reforms.
“Households that have invested in batteries are achieving significant savings, particularly when their battery is connected to a virtual power plant,” ACCC Commissioner Anna Brakey stated. The data indicates that homes with solar and battery systems recorded annual electricity bill reductions between approximately $329 and $909 (20-52%) compared to those relying solely on grid electricity. For the 24% of solar and battery customers actively participating in VPPs, the savings were even more substantial, with bills typically $762 to $1,093 (57-63%) lower.
The Alarming Rise in Consumer Complaints
Despite the clear financial benefits, the rapid uptake of home batteries has been accompanied by a significant spike in consumer issues. The ACCC reported a 107% increase in complaints about household batteries and new energy services to various consumer bodies over the past 12 months. These grievances range from performance problems and misleading or incomplete advice – including recommendations for oversized systems – to extended delays post-deposit and limited compatibility between different battery and VPP products.
“As more Australians invest in batteries and participate in virtual power plants, it’s critical that consumer protections keep pace,” ACCC Commissioner Anna Brakey said. “Consumers should be able to easily compare offers, switch providers, and fix issues if things go wrong, but gaps in the current suite of consumer protections are preventing people from being able to do so.”
The ACCC’s findings underscore the urgent need for enhanced consumer safeguards to ensure the long-term integrity and trust in Australia’s evolving energy market. The watchdog recommended an overarching duty to shift the onus onto energy providers to deliver promised benefits to customers, alongside other bolstered protections.
Virtual Power Plants: Balancing Reward and Risk
Virtual Power Plants (VPPs) are central to unlocking the highest savings for battery owners. These innovative energy services aggregate individual home batteries and other distributed energy resources, allowing a central operator to control them to support the broader grid. This can involve discharging stored energy back into the grid during peak demand or grid disturbances, thereby earning participants additional revenue or bill credits. This also helps reduce pressure on electricity networks and can avoid costly infrastructure upgrades, potentially leading to lower bills for all electricity customers.
However, the ACCC report highlights that VPPs are inherently complex, and customers often bear most of the risk associated with the operator’s performance. When joining a VPP, customers typically hand over control of their battery to an operator, and it is crucial that they fully understand the terms, conditions, and potential limitations before committing. The lack of compatibility between different battery systems and VPP products can also restrict a customer’s ability to switch providers, making informed choices paramount.

Australia’s Home Battery Boom Continues
The surge in battery installations is a direct result of government incentives and the rising cost of electricity. The federal government’s Cheaper Home Batteries Program, which commenced on 1 July 2025, offers an upfront discount on eligible battery systems, significantly reducing the initial investment for many households. This program, alongside increasing electricity prices, has driven a substantial increase in uptake. Over 400,000 batteries have been installed across Australia in the past 12 months, with a total installed capacity reaching 7.4GWh by Q1 2026. Australia is now recognised as the world’s third-largest home battery market.
Moreover, the average size of installed home battery systems is also growing, with national installations in Q1 2026 averaging 30.6 kWh of usable capacity, up from 19.7 kWh in Q3 2025. This trend towards larger systems reflects a desire for greater energy independence and resilience against grid outages.

What Households Should Consider
For Australians considering a home battery or VPP participation, the ACCC’s report offers critical advice:
- Understand the Offer: Thoroughly review contract terms, payment structures, and how your battery will be controlled by a VPP operator. Clarify how benefits are calculated and passed on to you.
- Compatibility: Investigate battery and inverter compatibility with various VPPs to ensure flexibility and avoid being locked into a single provider.
- Sizing: Ensure the proposed battery system is appropriately sized for your household’s energy consumption patterns and solar generation, rather than being oversold.
- Installer Reputation: Choose a Clean Energy Council (CEC) accredited installer with a strong track record and transparent quoting practices.
While the promise of lower bills and greater energy independence is compelling, exercising due diligence is essential to maximise the benefits and mitigate the risks in Australia’s rapidly evolving home battery market.
