Australia’s energy grid has experienced its most significant expansion of renewable generation and storage to date, with a record 9.1 GW of new capacity reaching full operational output in the National Electricity Market (NEM) during the 2025/26 financial year. This landmark achievement, detailed in the Australian Energy Market Operator’s (AEMO) latest Connections Scorecard released on 20 July 2026, represents more than double the 4.4 GW delivered in the previous financial year.
The surge in new connections underscores Australia’s rapid transition towards a cleaner energy future, with solar and battery projects playing a critical role in bolstering grid stability and increasing the supply of dispatchable power. The June quarter alone saw 3.9 GW of new capacity come online, contributing significantly to the annual total.
Battery Storage Dominates New Capacity
The AEMO report highlights a substantial increase in battery energy storage systems (BESS) coming online, reflecting the growing imperative to firm up intermittent renewable generation. Of the 9.1 GW total, standalone battery storage accounted for a remarkable 2.7 GW. Co-located solar and battery projects added another 500 MW, demonstrating an increasing trend among developers to integrate storage directly with new solar farms. Standalone solar capacity contributed 400 MW, alongside 200 MW of wind generation.
“A record 9.1 GW of new generation and storage capacity reached full output in the last financial year, more than double the result achieved in FY25,” stated Margarida Pimentel, AEMO’s Group Manager for Onboarding and Connections.
This robust influx of new assets is crucial for managing the grid’s stability as older, coal-fired power stations continue to retire. The ability of battery systems to rapidly respond to fluctuations in supply and demand is proving invaluable, shifting energy from periods of high solar generation to evening peaks. For homeowners considering how to leverage their own rooftop solar, understanding the broader grid’s evolution towards flexible capacity is key.

Expanding Pipeline Faces Implementation Hurdles
While the operational capacity additions are positive, AEMO’s scorecard also pointed to a continually expanding connections pipeline, which grew by 42% over the year to 75.4 GW. Battery projects continue to dominate this pipeline, representing 52% of the total capacity.
However, the report also flagged increasing challenges within the proponent implementation stage—the developer-led phase before a project formally registers with AEMO. The median duration for projects in this stage increased from 14 to 18 months in FY26, with a third of projects remaining there for over two years. AEMO attributes these delays to factors such as design changes, equipment substitutions, project sales, and extended financing activities.
This bottleneck highlights the complexity of delivering large-scale energy projects and the need for streamlined processes to ensure that proposed capacity translates into operational assets more efficiently. Despite these challenges, the overall performance demonstrates a strong commitment to Australia’s renewable energy targets.
New Capacity Added to NEM (FY26)
| Technology | Capacity Added (GW) |
|---|---|
| Standalone Battery | 2.7 |
| Co-located Solar+Battery | 0.5 |
| Standalone Solar | 0.4 |
| Wind | 0.2 |
| Total (Select) | 3.8 |
Note: The 9.1 GW total includes a broader range of generation and storage types across 34 projects. The table above highlights key solar and battery components mentioned explicitly in the report for the June quarter contributions to the annual total.
Implications for Australia’s Energy Future
The record 9.1 GW of new generation and storage capacity provides a strong foundation for Australia to meet its long-term energy goals. AEMO’s 2026 Integrated System Plan (ISP) calls for 35 GW of short and medium-duration storage and 5 GW of long-duration storage by 2050 to support a grid predominantly powered by solar and wind. The pace set in FY26 indicates that the near-term pipeline is capable of meeting the initial targets of this ambitious plan.
For households, this continued investment in large-scale renewables, particularly solar and batteries, contributes to a more resilient and eventually more affordable electricity supply. As more clean energy enters the grid, it helps to displace higher-cost fossil fuel generation, influencing wholesale electricity prices. This shift reinforces the value of residential solar installations and smart energy management.
