Melbourne, Victoria – Australia’s energy market has witnessed a significant shift this week, with global tech giant Amazon signing its first-ever standalone battery storage tolling agreement worldwide. The landmark deal, announced on September 3, 2026, secures a substantial 200 megawatt-hours (MWh) of storage capacity from the Bairnsdale battery energy storage system (BESS) in Victoria, setting a new precedent for corporate engagement in grid-scale energy solutions across Australia.
This agreement represents a pivotal moment, as it is not only Amazon’s inaugural standalone BESS tolling deal globally but also the first of its kind in Australia for a non-energy business. The move underscores a growing recognition among major corporations that supporting grid stability and decarbonisation requires direct investment in flexible energy infrastructure, beyond just renewable generation.
A New Model for Corporate Energy Procurement
The Bairnsdale BESS, a 50 megawatt (MW) / 200 MWh facility, is currently under development in Victoria. Amazon’s agreement is with Anza Power, the Australian subsidiary of US infrastructure investment firm I Squared Capital, which is developing the project. Under the terms of the tolling agreement, Amazon will gain access to the energy stored within the Bairnsdale BESS and will have the rights to control its charging and discharging cycles. In return, Amazon will pay Anza Power a regular fixed fee, without incurring the responsibilities of building or maintaining the facility itself.
This innovative commercial structure allows Amazon to leverage battery storage for its operational needs and sustainability goals, while providing Anza Power with a stable, long-term revenue stream for the asset. This model could prove attractive to other large energy consumers looking to manage their carbon footprint and ensure reliable power supply in an increasingly renewable-dominated grid.
Carlo Frigerio, Anza Chief Executive Officer, highlighted the significance of the agreement, stating, “Bairnsdale demonstrates our ability to deliver flexible energy infrastructure that respond to the evolving needs of both the market and our customers.”
Amazon’s Growing Australian Clean Energy Footprint
The Bairnsdale BESS deal is part of Amazon’s broader and aggressive clean energy strategy in Australia. Since 2020, the company has reportedly invested approximately A$2.8 billion in carbon-free energy projects across the country. This expansive portfolio includes solar, wind, and battery storage initiatives. Once completed, Amazon’s 20 Australian carbon-free energy projects are expected to provide nearly 1 gigawatt (GW) of new renewable capacity, equivalent to the annual consumption of over half a million Australian households.
Specifically for battery storage, Amazon has invested in seven battery projects in Victoria and a total of ten across Australia, which are projected to deliver a combined 368 MW of battery capacity. This substantial commitment reflects a strategic shift from merely adding renewable generation to actively investing in infrastructure that can manage the intermittency of solar and wind, ensuring electricity is available when and where it is needed.
Impact on Victoria’s Grid and the Broader Market
The addition of 200 MWh of flexible storage capacity from the Bairnsdale BESS will contribute directly to enhancing the stability and resilience of Victoria’s electricity grid. Battery energy storage systems play a critical role in firming renewable energy, absorbing surplus generation during periods of high solar or wind output, and discharging power back into the grid during peak demand or when renewable generation is low. This capability helps to smooth out supply fluctuations, prevent curtailment of renewable energy, and reduce reliance on fossil fuel generators for grid stability services.
“The agreement grants Amazon access to energy stored in the Bairnsdale BESS, as well as rights to control charging and discharging and use grid arbitrage.”
The ability for Amazon to engage in “grid arbitrage” through this tolling agreement indicates a sophisticated approach to energy management, where the battery can be charged during low-price periods and discharged when electricity prices are high, generating economic value while supporting grid balance. This kind of market participation is increasingly vital as Australia transitions towards a high-renewables grid. For homeowners and businesses, a more stable grid can translate to greater reliability and potentially more stable electricity prices. For those considering home battery storage, understanding the broader grid’s evolution, including the role of large-scale batteries, is key to maximising personal energy independence and savings.

This landmark deal also signals a potential evolution in how businesses interact with the energy market. Traditionally, corporate renewable energy procurement has focused on Power Purchase Agreements (PPAs) for generation assets. The Bairnsdale agreement suggests that direct investment in, or access to, storage capacity is becoming an equally important component of a comprehensive corporate energy strategy. This could pave the way for more non-energy companies to directly participate in the energy market, fostering further investment in battery storage and accelerating Australia’s clean energy transition. The sophistication of such arrangements highlights the increasing opportunities for dynamic energy management, echoing the principles behind residential Virtual Power Plants (VPPs) that allow aggregated home batteries to support the grid.

As Australia’s energy landscape continues to evolve, agreements like the Amazon-Anza Power deal demonstrate the diverse and innovative financial models emerging to support the deployment of critical energy storage infrastructure. This strategic move by Amazon in Victoria is a clear indicator of the growing maturity and attractiveness of Australia’s battery storage market for significant global players.
