Solar and Battery Projects Surge, Wind Plans Increase
In the past fortnight, a significant influx of solar and battery initiatives has emerged in the energy market operator’s grid management system, showcasing the strong interest from investors in both technologies, individually and as integrated solar-battery hybrids.
The initial addition was Acen Australia’s substantial 200 megawatt (MW), 400 megawatt-hour New England battery energy storage system (BESS), which has been strategically positioned alongside one of Australia’s largest photovoltaic projects, the 720MW New England solar farm.
Backing from the NSW Government
According to Renew Economy, the New England BESS has received support from the New South Wales government’s Emerging Energy Program, a $75 million initiative aimed at accelerating the development of new firm renewable sources as the state shifts away from coal reliance.
The solar element, with its first 400 MW stage completed at the beginning of last year, is also reinforced by a 20-year underwriting agreement from the NSW government.
Understanding the New England BESS
Geoff Eldridge from Global Power Energy clarifies that the New England BESS appears on the AEMO’s Market Management System (MMS) as two bidirectional battery units, each identified by distinct Dispatchable Unit Identifiers (DUIDs). Eldridge notes, “The New England BESS split across two DUIDs is a useful reminder that larger BESS projects can be recorded in MMS as multiple unit groupings rather than a singular line item.”
New Solar Farms on the Horizon
Also making their debut on the AEMO dashboard towards the end of last week were two solar farms: Global Power Generation’s 100 MW Bundaberg Solar Farm located in Queensland, and European Energy’s 80 MW Lancaster Solar Farm positioned in Victoria.
Interestingly, both projects have secured power purchase agreements with notable corporate clients: Telstra for the Bundaberg initiative and Apple for the Lancaster installation. Consequently, as Eldridge points out, these projects are categorized by AEMO as semi-scheduled generating units.
Wind Projects Gaining Momentum
While solar and battery projects dominate the grid management updates this month, new wind initiatives have taken the lead in the federal EPBC assessment queue, indicating a potential resurgence for wind power in 2026.
Recent additions to the federal environmental assessment queue include the Twin Hills wind farm, which proposes up to 110 turbines and a battery, located 30 km north-east of Eneabba and 260 km north of Perth in Western Australia. Another proposal from Equis Wind Australia seeks to establish a 600 MW wind farm along with “associated ancillary infrastructure” in Jackson North, approximately 35 km south-west of Wandoan in Queensland.
