Australia Adds Record 9.1 GW of Renewables, Pipeline Is Growing Faster Than Completions

The Australian Energy Market Operator (AEMO) has reported that 9.1 GW and 12.9 GWh of new solar, wind and battery storage capacity across 34 projects reached full output in the National Electricity Market during the 2025/26 financial year, according to AEMO's latest Connections Scorecard. That is more than double the 4.4 GW delivered the previous financial year, marking the strongest year yet for large-scale renewable project completions in the NEM.

Batteries Are Doing Most of the Work

Of the June quarter's 3.9 GW of capacity reaching full output, standalone battery storage accounted for 2.7 GW, well ahead of the quarter's 400 MW of standalone solar, 500 MW of co-located solar-and-battery capacity, and 200 MW of wind. Battery projects represent 52% of total capacity in AEMO's broader connections pipeline, and 2.4 GW of previously solar-only projects added battery storage systems during the year, on top of new hybrid solar-plus-battery applications making up 4.3 GW, or 18%, of the year's applications. Storage has moved from a secondary feature to the dominant category shaping what actually gets built.

The Pipeline Is Growing Faster Than Completions

AEMO's overall connections pipeline expanded 42% over the year, from 53 GW to 75.4 GW, and capacity in the application stage more than doubled. That gap, a pipeline growing faster than the rate of projects actually reaching full output, is a detail worth reading carefully rather than only citing the headline completion figure, since it points to where the bottleneck in Australia's build-out actually sits.

Where Projects Are Actually Getting Stuck

AEMO's own data identifies the proponent implementation stage, the developer-led phase between application approval and construction reaching completion, as the specific point where delays are concentrated. The median duration of this stage rose from 14 to 18 months over the year, and roughly a third of projects have now spent more than two years in it. AEMO cites design changes, equipment substitutions, project sales and extended financing processes as contributing factors, rather than grid connection approval itself, which is the stage AEMO more directly controls.

Reading the Record Figure in Context

AEMO's own characterization is that the year demonstrated strong end-to-end pipeline performance despite these delays, a view consistent with the completion figure more than doubling year on year even as the implementation-stage bottleneck lengthened. Both things can be true simultaneously: completions reaching a record high, and the specific stage most exposed to project-level risk, financing, equipment sourcing, ownership changes, taking longer to clear than it did the year before.

Why This Matters Beyond Domestic Power Supply

Abundant, low-cost renewable electricity is a precondition for the green hydrogen, ammonia and e-fuel production Australia has separately positioned itself to supply, including the Pilbara ammonia bunkering trials and CCUS hub studies this series has referenced. Electrolysis-based fuel production is electricity-intensive, and its cost is directly tied to the price and availability of the renewable power feeding it. A domestic grid adding record renewable and storage capacity strengthens the underlying case for Australia's fuel export ambitions.
