Australia’s clean energy transition is accelerating with record renewable electricity generation, rapid growth in battery storage, stronger climate targets, and major government investment in clean manufacturing.
However, new analysis from the Clean Energy Council (CEC), the Clean Energy Regulator (CER), and the Institute for Energy Economics and Financial Analysis (IEEFA) indicates that slower utility-scale renewable investment, transmission bottlenecks, and heavy reliance on imported fuels continue to challenge the country’s path toward its 2030 and 2050 climate goals.
The Australian Government has reinforced its industrial strategy through the AUD 22.7 billion Future Made in Australia Act, which aims to expand domestic manufacturing of renewable energy technologies, batteries, hydrogen, and critical minerals while strengthening local supply chains and attracting private investment, IEEFA report said.
Despite long-term policy support, investment in utility-scale renewable energy slowed significantly during the latest reporting period. Only 2.3 GW of renewable energy projects reached Final Investment Decision (FID), representing a 46 percent decline from the previous year. Investment in onshore wind projects fell 59 percent, while utility-scale solar investment declined 29 percent. The slowdown is not due to a lack of available capital. According to the Investors Group on Climate Change, Australian institutional investors manage approximately AUD 3.5 trillion under net-zero commitments, yet nearly three-quarters of investment managers report an insufficient pipeline of commercially mature renewable energy projects because of transmission delays, planning approvals, grid congestion, and lengthy permitting processes.
Australia continues to achieve record renewable electricity generation. Renewable energy supplied 42.7 percent of the nation’s electricity, up from 39 percent a year earlier, marking the first time renewable generation exceeded fossil fuel generation during a peak quarter.
Solar energy remains Australia’s fastest-growing renewable resource. The country has installed 45.1 GW of cumulative solar capacity, including 28.3 GW generated by more than 4.3 million rooftop solar systems. Rooftop solar capacity now exceeds the country’s remaining coal-fired generation fleet, highlighting the rapid transformation of Australia’s electricity sector. The average residential rooftop solar installation has increased to 10.9 kW, and with support from initiatives such as the Cheaper Home Batteries Program, many households are estimated to save around AUD 1,500 annually on electricity costs.
Wind energy also continues to expand. Australia has approximately 18.8 GW of installed wind capacity, producing 61 percent of all Large-scale Generation Certificates. More than 12 GW of additional wind generation remains under development, supporting the gradual retirement of coal-fired power stations.
Battery energy storage has become one of Australia’s fastest-growing renewable energy segments. During the latest investment cycle, 4.3 GW of battery storage projects worth approximately AUD 4.8 billion secured financial commitments, making Australia the world’s third-largest utility-scale battery market after China and the United States. Residential battery adoption has also surged, with installations increasing 260 percent year over year, adding more than 268,000 home battery systems that improve energy resilience, increase rooftop solar self-consumption, and reduce pressure on electricity networks during peak demand.
Australia is also investing in next-generation storage technologies. The State Electricity Commission of Victoria has partnered with Energy Dome to develop the state’s first carbon dioxide-based long-duration energy storage facility, supporting greater renewable energy integration into the electricity grid.
Climate policy continues to strengthen under the Climate Change Act. Australia aims to reduce greenhouse gas emissions by 43 percent below 2005 levels by 2030 while increasing renewable electricity generation to 82 percent of the national grid. The Capacity Investment Scheme will support approximately 40 GW of new renewable generation and dispatchable energy capacity.
Looking beyond 2030, Australia’s updated Nationally Determined Contribution targets emissions reductions of 62 percent to 70 percent below 2005 levels by 2035, while improving national energy efficiency by 25 percent. The country continues to target net zero emissions by 2050, with renewable electricity expected to supply approximately 97 percent of the national electricity grid.
Corporate climate reporting is also becoming more comprehensive. Under the Australian Sustainability Reporting Standards (AASB S2), large companies will begin reporting Scope 3 value chain emissions from their second reporting year beginning in 2027, extending mandatory climate disclosure requirements beyond listed companies to many large private businesses.
While renewable electricity continues to expand, Australia remains heavily dependent on imported liquid fuels. IEEFA estimates that approximately 80 percent of Australia’s refined petroleum products are imported following the closure of much of the country’s refining capacity over the past two decades. National strategic fuel reserves currently cover only around 50 days of net fuel imports, well below the International Energy Agency’s 90-day stockholding recommendation, leaving the country vulnerable to shipping disruptions and geopolitical tensions.
Industry investment in flexible generation is also supporting grid reliability. Renewable Energy Partners is advancing the proposed 850 MW Allawah Gas Power Generator in Queensland alongside the 1,000 MW Lake Dalrymple Wind Farm and the Bogunda Energy Hub. Squadron Energy is constructing the 64 MW Dubbo Firming Power Station, a hydrogen-ready facility, while also progressing a larger 300 MW to 400 MW gas firming project in New South Wales. Meanwhile, Elements Green has redesigned its Eurimbula solar project, reducing the planned solar footprint from 1,173 hectares to 545 hectares to align with changing electricity demand, environmental requirements, and evolving corporate power purchase agreements.
Australia’s renewable energy sector continues to deliver record generation, expanding battery storage, and stronger climate policies, but achieving its 2030 renewable electricity target and 2050 net zero ambition will depend on accelerating project approvals, expanding transmission infrastructure, overcoming investment bottlenecks, and strengthening long-term energy security alongside clean energy growth.
