Predictions for 2026: What’s Next in Australia’s Renewable Journey
As Australia continues its transition towards renewable energy, 2026 is poised to be a pivotal year. Key developments are anticipated in renewable energy capacity expansion, advancements in energy storage solutions, and the integration of virtual power plants (VPPs) into the national grid.
Expansion of Renewable Energy Capacity
Australia's renewable energy sector is set for significant growth by 2026. The Australian government has launched its Capacity Investment Scheme (CIS) Tender 4, aiming to allocate an indicative target of 6 GW of renewable energy generation across the National Electricity Market (NEM). This auction plans to distribute 2.2 GW in New South Wales, 1.4 GW in Victoria, and 300 MW each in South Australia and Tasmania, with the remaining capacity open to eligible projects from all NEM jurisdictions.
The International Energy Agency (IEA) forecasts that Australia's renewable energy capacity additions will gradually rise in the coming years, from 5.4 GW in 2024 and 5.5 GW in 2025 to 6 GW in 2026, 6.9 GW in 2027, and 8 GW in 2028. Additions are expected to peak in 2029 at 11.5 GW before slightly decreasing to 9 GW in 2030.
This expansion is expected to drive a construction boom, with renewable energy development forecasted to reach $20 billion annually by 2026/27, leading to unprecedented growth in Australia's utilities construction sector.
Advancements in Energy Storage Solutions
To support the increasing share of renewables, significant investments in energy storage are underway. Companies like Akaysha Energy, backed by BlackRock, are developing large-scale battery storage projects across Australia. One notable project is the $200 million Brendale battery in Queensland, capable of powering 300,000 homes, set to commence operations in 2026 using Tesla technology.
EnergyAustralia is also advancing two battery projects in Victoria and South Australia after securing government support through the Capacity Investment Scheme. These projects, Wooreen in Victoria and Hallett in South Australia, will utilize existing infrastructure to supply additional capacity to the market and are expected to be operational by 2026 and 2027, respectively.
These developments are crucial as Australia aims to maintain grid reliability during the transition from coal to renewable energy. The Australian Energy Market Operator (AEMO) emphasizes the importance of timely delivery of new energy projects, including solar, wind, batteries, pumped hydro, and transmission links, to ensure a stable electricity supply.
Integration of Virtual Power Plants
The integration of Virtual Power Plants (VPPs) is set to revolutionize Australia's energy market by 2026. The Australian Energy Market Commission (AEMC) has released a final determination to enable VPPs to compete directly with large-scale generators. This reform, taking effect from May 2027, aims to create efficiencies by allowing VPPs, commercial and industrial demand response, and aggregated batteries to compete directly with traditional power stations. An incentive scheme will be available to early participants from April 2026.
VPPs aggregate distributed energy resources, such as rooftop solar panels and home batteries, to operate as a single power plant. This approach enhances grid stability and allows for more efficient use of renewable energy. The AEMC's reform is expected to benefit consumers through significant cost savings, lower emissions, and reduced energy prices.
As these developments unfold, Australia's renewable energy landscape in 2026 is set to be characterized by substantial capacity expansions, advanced energy storage solutions, and innovative grid integration strategies, all contributing to a more sustainable and reliable energy future.
