Australian households participating in Virtual Power Plants (VPPs) are consistently recording some of the nation’s lowest electricity bills, according to the Australian Competition and Consumer Commission’s (ACCC) 15th electricity market inquiry report, published on 10 July 2026. The report underscores the significant benefits consumer energy resources (CERs), such as home batteries, are delivering to households and the broader energy system, driven in part by government initiatives like the Cheaper Home Batteries Program.
The ACCC’s latest findings reinforce the growing importance of distributed energy assets in maintaining affordability and reliability across Australia’s National Electricity Market (NEM). The report, which provided an update to the Treasurer on 12 June 2026 and was subsequently published, examined electricity billing outcomes for households and small businesses across Victoria, South Australia, New South Wales, and South East Queensland.
VPPs: A Path to Lower Bills Confirmed
The inquiry specifically focused on customers who have installed batteries and those actively participating in VPPs. It found that these households are achieving substantial reductions in their energy costs. Louisa Kinnear, Chief Executive of the Australian Energy Council (AEC), the peak body for energy retailers and generators, affirmed that the ACCC’s report demonstrates the tangible value of retailer-led VPP products through lower bills and increased participation in the energy system.
“The ACCC’s report demonstrates the value retailer-led virtual power plant products can deliver for customers through lower bills and greater participation in the energy system.”
This outcome is largely attributed to the strategic deployment of home batteries, which enables households to store excess solar generation and discharge it during peak demand periods, reducing reliance on grid electricity when prices are highest. The ACCC report was informed by residential pricing data from retailers covering 89% of residential customers and additional information on VPPs from 13 electricity retailers and 4 new energy services providers.
The Role of Home Batteries and Government Programs
The significant increase in battery installations, spurred by programs like the Australian Government’s Cheaper Home Batteries Program, has been a key factor in these savings. By coordinating these individual home batteries, VPPs can act as a collective power plant, supplying electricity back to the grid during times of high demand or drawing from it during periods of abundant, cheap renewable generation. This collective action not only benefits participating households but also contributes to greater grid stability and can help reduce overall electricity system costs.
According to CSIRO’s GenCost report, published on 14 July 2026, the deployment of 6–8 gigawatts of batteries in just a few years has transformed the dynamics of the evening peak, with batteries now setting prices instead of following them. This has led to generation prices falling rapidly, reaching levels not seen since before the Ukraine war, around AUD$60–$80/MWh. These wholesale price reductions are gradually flowing through to retail prices, with the Default Market Offer (DMO) having fallen by approximately 10 per cent.

Unlocking Greater Value and Consumer Protections
The ACCC’s report also highlighted opportunities to unlock even greater value from customer batteries across the energy system. Ms Kinnear noted that while VPPs are already delivering significant savings, more needs to be done to ensure the full value created by customer batteries is shared with households through competitive energy products. This includes examining how network incentives can better support customer participation, as outlined in the Australian Energy Market Commission’s (AEMC) upcoming Electricity Network Regulation Review.
Furthermore, the report examined consumer risks associated with investments in battery and solar systems and VPP participation, advocating for enhanced consumer protections to build greater trust and increase uptake.

The findings signal a clear direction for Australia’s energy future, where active consumer participation through CERs and VPPs will be critical in achieving the energy transition at the lowest cost for consumers, while simultaneously driving down individual household electricity bills.
