Analysis
QIC has agreed to buy AGL Energy’s remaining 19.9% stake in Tilt Renewables, a deal that will leave QIC with a near-total holding of the platform at 99.9%. The transaction, announced on 10 November 2025, cements QIC’s control of one of Australia’s largest operating wind businesses and accelerates its ability to deploy capital into development and storage opportunities.
The purchase consolidates a local ownership base that already includes the Australian sovereign investor Future Fund, positioning Tilt to convert a substantial pipeline into construction starts. Tilt currently manages a diversified operating portfolio of approximately 1.9GW across 12 assets and says it has more than 1.6GW of development projects expected to progress to Final Investment Decision over the next 12 months.
Ross Israel, QIC’s Head of Global Infrastructure, described the move as a strategic step to scale up delivery in a market where wind is set to dominate new large-scale generation. He highlighted the structural drivers behind the strategy, including strong policy support, rising corporate and utility offtake demand, and the need for integrated generation-plus-storage solutions.
Patrick Mulholland, QIC Global Infrastructure Partner, framed the deal as the latest chapter in a long-running commitment to Tilt that began in 2016. Under QIC and partner ownership the business has grown from a small seed portfolio to an extensive operating platform, a track record the firm says de-risks near-term construction and supports broader electrification objectives across states.
Tilt’s CEO, Anthony Fowler, welcomed the strengthened local ownership and signalled confidence in near-term milestones: two of Tilt’s projects are targeted to reach Final Investment Decision in 2025, potentially becoming among the first large-scale wind projects to do so in Australia this year. The company also points to recent operational wins including completion of the Rye Park wind farm in New South Wales in 2024 and commissioning of a battery energy storage system in the Latrobe Valley earlier in 2025.
The deal also reinforces existing commercial ties: AGL has previously committed to Power Purchase Agreements with Tilt for the Palmer Wind Farm in South Australia and the Waddi Wind Farm in Western Australia, both still in development. Market participants say consolidation like this can speed delivery of integrated renewables-plus-storage assets — a priority as grid operators manage increasing intermittent generation.
From an industry perspective, the transaction underscores two trends: consolidation by large infrastructure managers seeking scale in build-outs, and widening investor appetite for projects that combine generation with storage. While the move reduces minority liquidity, it gives QIC and its partners greater optionality to turn the 1.6GW pipeline into shovel-ready projects — a crucial pathway as Australia targets deeper decarbonisation of its electricity system.
