Western Australian households are set to benefit from a significant expansion of community battery infrastructure, with the Albanese and Cook Labor Governments announcing construction is now underway for 18 new community battery energy storage systems (BESS). This initiative, backed by a $9.34 million federal investment, aims to enhance grid stability, reduce emissions, and put downward pressure on electricity bills for thousands of residents across Perth and Bunbury. The new batteries are slated to be online by mid-2027.
This latest deployment will add a combined 6.6 megawatts (MW) of storage capacity to the state’s grid, marking a crucial step in Western Australia’s transition to a cleaner, more resilient energy future. The batteries, installed by Western Power, are strategically located to harness the state’s abundant rooftop solar generation, storing excess energy during the day for redeployment during the evening peak demand periods.
Targeted Deployment Across Perth and Bunbury
The 18 new community batteries comprise 13 low-voltage units distributed across various Perth metropolitan suburbs and five larger medium-voltage batteries destined for Bunbury. These locations were chosen following extensive consultation with local government and residents, targeting areas with high rooftop solar penetration to maximise their impact.
Each metropolitan battery in Perth is designed to connect approximately 130 households, while the five larger Bunbury sites will collectively serve around 3,600 households. This distributed approach allows for localised energy management, preventing solar curtailment and ensuring more residents can benefit from their rooftop solar investments, even when the sun isn’t shining.
“These additional 18 batteries being delivered across metropolitan Perth and Bunbury will help lower emissions, put downward pressure on energy costs and improve local power reliability.” – Amber-Jade Sanderson MLA, WA Minister for Energy and Decarbonisation
Federal Investment and Broader Support
The $9.34 million federal contribution comes from Round 1 of the Australian Renewable Energy Agency (ARENA) Community Battery program, forming part of a larger $25 million total project cost. This funding underscores the Albanese Government’s commitment to supporting decentralised energy solutions that empower communities and bolster the National Electricity Market (NEM) transition.
This isn’t Western Australia’s first foray into community batteries. The Albanese Government has already rolled out five community batteries across Perth in areas including Coogee, Bayswater, Stratton, Kinross, and Port Kennedy, under the broader Community Batteries for Household Solar program. These early deployments have laid the groundwork for the current expansion, demonstrating the tangible benefits of localised energy storage.
Beyond community-scale solutions, Western Australia has seen significant uptake in residential battery storage. More than 45,000 households and small businesses in WA have installed home batteries through the federal ‘Cheaper Home Batteries Program’. For those considering individual home battery systems, understanding available incentives is crucial.

Impact on Energy Bills and Grid Stability
The primary benefit of these community batteries for consumers is the potential for reduced electricity bills. By storing excess solar power, households can draw on this cheaper, cleaner energy during peak times, rather than relying on more expensive grid electricity. This not only directly saves money for connected homes but also helps stabilise the wider grid by reducing demand spikes, which can indirectly benefit all consumers.
Furthermore, these batteries play a vital role in improving grid stability and reliability. As more intermittent renewable energy sources like solar and wind come online, energy storage becomes critical for balancing supply and demand. The ability to charge when generation is high and discharge when demand outstrips immediate supply ensures a more consistent and secure energy flow. This aligns with broader efforts to integrate smart energy solutions into Australian homes and grids, as explored in articles like Smart Home Energy Systems: Slash Your 2026 Australian Electricity Bills by Up To 30%.
The state’s energy transition is also being bolstered by large-scale projects. The latest Capacity Investment Scheme (CIS) tender in Western Australia recently backed 1.9 gigawatts (GW) of new renewable generation and 482 MW of battery storage across 10 new projects in regional WA. This multi-faceted approach, combining utility-scale, community-scale, and household-level batteries, positions Western Australia as a leader in Australia’s energy storage landscape.
The Future of WA’s Energy Grid
The ongoing commitment to battery storage, both at a community and utility scale, reflects a strategic shift towards a more distributed and resilient energy network. These projects are crucial for achieving WA’s ambitious renewable energy targets and ensuring that the benefits of clean energy are accessible and affordable for all. As these 18 new community batteries come online by mid-2027, they will further cement Western Australia’s position at the forefront of Australia’s energy transformation, providing tangible financial and environmental benefits to its residents.
