Australia's grid connection pipeline jumps 43% to 80.9 GW, overtaking existing capacity, led by batteries

Australia's National Electricity Market connection pipeline grew 43% in a year to 80.9 GW, exceeding the grid's 77 GW of operating capacity for the first time, according to the Australian Energy Market Operator's third-quarter connections scorecard. Grid-scale battery storage accounts for 55% of proposed capacity as solar output reshapes wholesale prices.

Solar and battery storage projects have pushed Australia's National Electricity Market (NEM) connection pipeline up 43% in a year to 80.9 GW, overtaking the grid's existing 77 GW of operating capacity for the first time, PV Tech reported, citing the Australian Energy Market Operator's (AEMO) third-quarter connections scorecard.

Grid-scale battery storage accounts for 55% of pipeline capacity, with wind at 15%, hybrid solar-plus-storage at 19%, standalone solar at 5%, hydro at 5% and gas at 1%. In the third quarter of 2026 alone, battery storage made up 19 new connection applications totalling 5.8 GW, or 76% of newly submitted capacity, and nearly 40% of battery projects in the pipeline can deliver between three and ten hours of storage.

The connection rush coincides with record solar output that is reshaping wholesale market economics. Combined utility-scale and rooftop solar generation in the NEM reached 4,780 GWh in September, the strongest September in the dataset, with utility-scale plants generating 1,805 GWh, up 36.9% year over year. Wholesale price pressure followed: rooftop solar recorded a negative daily average price on 10 of the month's 30 days, while utility-scale solar averaged about AU$23.90 per MWh.

AEMO noted that around 15 GW of existing generation is scheduled to retire over the coming decade while electricity consumption is forecast to rise by more than 40%, making timely delivery of flexible storage capacity central to system reliability as legacy coal and gas plants exit.
