First Stage of Australia’s Second-Biggest Battery Starts Commercial Operations in the Sunshine State

Why It Matters

Supernode’s scale and long‑term financing demonstrate accelerating investment in grid‑scale storage, essential for meeting Queensland’s peak‑demand and Australia’s renewable transition. Its partnership model also signals growing confidence from utilities in large‑scale battery tolling as a revenue source.

Key Takeaways

• Stage‑1 Supernode 260 MW/619 MWh now operational
• Project aims for 780 MW/3,074 MWh by 2027
• Origin Energy has 12‑year tolling for Stages 1‑2
• Financing represents Australia’s largest standalone BESS debt deal
• Stage 4 will host Quinbrook’s EnerQB long‑duration storage

Pulse Analysis

Australia’s grid is under increasing pressure to balance rising renewable generation with evening peak demand, and large‑scale battery storage is emerging as a critical solution. The Supernode project, located at the South Pine substation, adds 260 MW of dispatchable capacity that can shave peaks for nearly 190,000 households. By delivering power during high‑price periods, the battery not only stabilises the network but also creates a new revenue stream for energy retailers through tolling agreements, a model that is gaining traction across the National Electricity Market.

The Supernode rollout is notable for its ambitious scale and financing structure. Quinbrook’s investment of over $1.4 billion for the first three stages, coupled with the largest standalone BESS debt financing in Australian history, underscores strong investor confidence. Origin Energy’s 12‑year off‑take contracts for the initial stages guarantee a steady cash flow, while the partnership with Private Energy Partners ensures local procurement and job creation in South‑East Queensland. These elements collectively reduce project risk and set a benchmark for future utility‑scale storage developments.

Looking ahead, Supernode’s planned Stage 4 will introduce Quinbrook’s EnerQB long‑duration storage technology, a partnership with CATL that could extend discharge times well beyond conventional batteries. This capability is pivotal for deep‑renewable integration, providing firming services when solar and wind output wanes. As Supernode and competing projects like the Eraring battery vie for the title of the nation’s largest storage asset, the market is likely to see accelerated deployment, tighter pricing, and broader adoption of tolling models, all of which will shape Australia’s energy transition over the next decade.
