A new report shows that more renewable generation capacity – led predominantly by solar farms and hybrid solar-and-battery projects – reached financial close, and more large-scale battery energy storage was switched on across Australia in the first half of the year than across all of 2025.
The Clean Energy Council’s (CEC) “Bi-annual investment report: Large-scale renewable generation and storage (January-June 2026)” ” also shows that five generation projects totalling 1.4 GW of new capacity and worth more than AUD 2.8 billion ($1.97 billion) were commissioned and started operations during the first half of this year.
The CEC said the rolling 12-month quarterly average for newly commissioned capacity has now reached 912 MW, up 56% compared to the same period 12 months ago, and the highest rolling average seen since the first quarter of 2022. A further eight generation projects totaling about 1.9 GW began construction in the first half of 2026.
In addition to the new generation projects, nine battery energy storage projects worth $4.3 billion and representing 2.3 GW/7.1 GWh of storage capacity were also switched on in the first six months of the year, surpassing the 2 GW/5.1 GWh added during 2025.
3 GW across all of last year. Utility-scale solar drove the new commitments with 11 of the 12 projects solar or solar hybrids with one onshore wind project also reaching financial close.
