Quinbrook Infrastructure Partners
Quinbrook Infrastructure Partners was founded in 2014 by Rory Quinlan and David Scaysbrook, both former executives at Babcock & Brown and other infrastructure firms. The firm targets mid-market infrastructure investments in energy transition, renewable power generation, and related technology. Its strategy spans solar, wind, battery storage, hydrogen, and grid-supporting assets, with a focus on high-growth regions. The firm's investment portfolio includes holdings in North American solar and storage platforms such as Intersect Power, as well as Australian renewable hydrogen projects. Quinbrook typically seeks control or co-control equity positions, often partnering with developers and energy companies. Its geographic footprint covers the United States, the United Kingdom, and Australia, with additional operations in Continental Europe. Quinbrook's team includes over 100 professionals across offices in London, Houston, Newport Beach, and Brisbane. In 2023, the firm closed Quinbrook Infrastructure Partners IV at $4.4B, exceeding its target (per Reuters, October 2023). The firm also operates a separate credit arm, Quinbrook Credit Partners, and a dedicated sustainability advisory team. A structural differentiator is Quinbrook's integrated approach: it combines asset management with development and operational expertise, often incubating projects before commercialization. The firm's co-founders retain direct involvement in deal sourcing, and the partnership structure avoids a traditional GP/LP friction. Quinbrook's mandate explicitly avoids consumer-facing assets and fossil-fuel-dependent operations.

Frequently asked questions
Who runs investment decisions at Quinbrook Infrastructure Partners?
Investment decisions are led by co-founders and managing partners Rory Quinlan and David Scaysbrook, who remain active in deal sourcing and portfolio management. The firm uses a sector-specialized investment committee structure. Both principals have backgrounds in infrastructure finance at Babcock & Brown and other firms (per public record).
How does Quinbrook source proprietary deal flow?
Quinbrook sources deals through direct developer relationships, long-term partnerships with energy companies, and its own in-house development team. The firm often incubates projects from early stages, which provides proprietary access. Its network spans regulators, utilities, and technology partners across key markets.
Is Quinbrook structured as a single family office or does it operate more like an asset manager?
Quinbrook is structured as an independent asset manager, not a family office. It operates a traditional fund structure with institutional limited partners, including pension funds, endowments, and sovereign wealth funds. The firm has raised multiple closed-end infrastructure funds.
What investment stages does Quinbrook typically target?
The firm targets mid-market control and co-control investments, typically in operational assets or late-stage development projects. It also engages in greenfield development via its in-house team. Sector focus is exclusively on energy transition and critical infrastructure, avoiding growth equity or venture-stage deals.
Does Quinbrook participate in fund commitments or only direct deals?
Quinbrook primarily makes direct investments, but also manages separate accounts and co-investments alongside limited partners. It does not operate fund-of-funds or primary fund commitment strategies. The firm's credit arm provides debt solutions to infrastructure projects.
Which sectors does Quinbrook explicitly avoid?
Quinbrook avoids fossil fuel extraction, pipeline infrastructure, and consumer-facing assets. Its mandate is strictly focused on energy transition, renewable power, and enabling grid infrastructure. The firm also avoids leveraged buyouts or distressed turnaround situations.
Where does the underlying wealth come from?
Quinbrook is not a family office; its capital base comes from institutional limited partners. The co-founders' personal wealth is derived from their prior careers in infrastructure finance and their equity in the firm. No single-family wealth or dynasty fortune backs the firm.
