Australia’s Biggest Wind Project and 8 Battery Hybrids Among 19 Winners of Largest CIS Renewable Auction

Why It Matters

The expanded CIS awards accelerate Australia’s transition to cheap, clean energy, reinforcing grid reliability and pressuring power prices downward. By securing billions in investment and thousands of jobs, the auction strengthens regional economies and supports the country’s 2030 renewable target.

Key Takeaways

• Origin Energy’s 1.45 GW Yanco Delta wind wins CIS, unlocking $17 bn.
• Eight hybrid projects combine wind/solar with battery storage, boosting firm capacity.
• Queensland’s Bungaban wind‑battery project secures Rio Tinto PPA for smelters.
• Tender 7 awarded 7.8 GW, exceeding 5 GW target, creating 19,000 jobs.
• NSW fills CIS quota; next tender will exclude the state.

Pulse Analysis

The federal Capacity Investment Scheme, introduced in 2022 to fast‑track low‑cost clean power, held its seventh tender in early May. While the auction originally sought 5 GW of new generation, the underwriters committed to 7.8 GW, reflecting strong developer confidence and a competitive pricing environment. Origin Energy’s 1.45 GW Yanco Delta wind farm emerged as the headline project, and the overall package is expected to mobilise roughly $17 billion of private capital and generate 19,000 construction jobs. These figures underscore the CIS’s role as a catalyst for Australia’s 82 percent renewable electricity target by 2030.

A distinctive feature of Tender 7 is the prominence of wind‑solar‑battery hybrids, with eight projects blending intermittent generation with storage. Queensland’s 1.15 GW Bungaban wind‑battery scheme, already linked to a long‑term power purchase agreement with Rio Tinto, illustrates how industrial PPAs are unlocking financing for hybrid assets that can supply smelters and refineries around the clock. Similarly, the 600 MW Birriwa solar‑battery hybrid in New South Wales adds 2.4 GWh of storage, enhancing firm capacity and reducing reliance on fossil‑fuel peakers. These configurations are critical for stabilising the National Electricity Market as coal and gas retire.

The next round, Tender 9, slated for May 25, will again target 5 GW but will exclude New South Wales, which has already met its quota and is running a state‑level auction focused on wind‑solar hybrids. Analysts caution that while the CIS has accelerated project pipelines, only a fraction of earlier winners have reached financial close, raising questions about execution risk. Nevertheless, the infusion of $1.2 billion in social‑license commitments and $257 million of domestic steel use signals broader economic benefits, positioning the scheme as a template for future clean‑energy financing worldwide.
