Solar and Battery Projects Surge, Wind Plans Accumulate
Recently, there has been a significant influx of solar and battery initiatives entering the energy market operator’s grid management system, emphasising the growing interest among investors in these technologies, including the emerging solar-battery hybrids.
The most notable development occurred last week with Acen Australia unveiling its 200-megawatt (MW), 400 megawatt-hour New England battery energy storage system (BESS), strategically located alongside one of the largest photovoltaic projects in the country, the 720MW New England solar farm.
Support from Government Initiatives
As reported by Renew Economy, the New England BESS received backing from the NSW government’s Emerging Energy Program, which features a $75 million fund aimed at accelerating the deployment of reliable renewable energy sources in anticipation of a shift away from coal.
The solar segment of the project, which saw the completion of its first 400 MW phase by the beginning of last year, has also been secured by a 20-year underwriting agreement from the NSW state government.
Detailed Insights on BESS Configuration
Geoff Eldridge from Global Power Energy clarified that the New England BESS is represented in the AEMO’s Market Management System (MMS) as two battery units, each registered under distinct Dispatchable Unit Identifiers (DUIDs).
“The division of the New England BESS into two DUIDs serves as a reminder that larger battery energy storage system projects can be listed in the MMS as multiple unit configurations rather than a single entity,” Eldridge elaborated.
New Solar Ventures Under AEMO Oversight
Additionally, towards the end of last week, two new solar farms joined the AEMO dashboard: Global Power Generation’s 100 MW Bundaberg Solar Farm in Queensland and European Energy’s 80 MW Lancaster Solar Farm in Victoria.
Notably, both projects are underpinned by power purchase agreements with prominent corporate clients, namely Telstra for the Bundaberg initiative and Apple for the Lancaster site. As noted by Eldridge, this results in both solar farms being categorised as semi-scheduled generating units within AEMO’s framework.
Wind Energy Projects Gaining Momentum
While solar and battery technologies are making strides in the grid management system this month, the most recent new projects entering the federal Environment Protection and Biodiversity Conservation (EPBC) queue are primarily wind initiatives. This trend may indicate a potential resurgence for wind power in 2026.
The latest to join the queue for federal environmental evaluation is the Twin Hills wind farm, which is projected to feature up to 110 turbines along with a battery, proposed by Wind Prospect located 30 km north-east of Eneabba and approximately 260 km north of Perth, Western Australia.
In addition, Equis Wind Australia has put forth a proposal for a substantial 600 MW wind farm coupled with “associated ancillary infrastructure” at Jackson North, around 35 km south-west of Wandoan in Queensland.
