Fund Exceeds Target as Investor Demand Strengthens
Energy transition-focused investor Quinbrook Infrastructure Partners has completed the final close of its Quinbrook Renewables Impact Fund II (QRIF II), securing £587 million (USD$784 million) in investor commitments, significantly exceeding its original £500 million target.
The successful fundraising reflects growing institutional investor appetite for renewable energy infrastructure that combines stable long-term financial returns with measurable climate impact. According to Quinbrook, the strong response also highlights increasing confidence in clean energy assets across the United Kingdom and Ireland, where governments continue accelerating the transition toward lower-carbon electricity systems.
The company noted that investor demand was particularly strong because the portfolio consists primarily of infrastructure projects backed by long-term, inflation-linked contracts, providing predictable revenues alongside environmental benefits.
Supporting the UK’s Clean Energy Transition

QRIF II has been established to finance renewable energy generation, battery storage systems, electricity grid support infrastructure, and other clean energy assets across the United Kingdom and Ireland.
The investment strategy is designed to help deliver the infrastructure needed to support the UK Clean Power 2030 ambitions while contributing to Ireland’s 80% renewable electricity target.
Beyond expanding renewable electricity generation, the fund seeks to strengthen energy security by investing in technologies that improve grid flexibility and reliability as renewable energy penetration increases.
According to Quinbrook, these investments are expected to play an increasingly important role as electricity systems accommodate larger volumes of intermittent wind and solar generation.
Growing Demand for Renewable Infrastructure
Commenting on the successful fundraising, Mark Burrows, Managing Director and Head of Relationships and Fundraising for Europe at Quinbrook, said investor demand demonstrates growing confidence in high-quality clean energy infrastructure assets.
He noted that both the speed at which the fund reached its target and the level of investor participation illustrate the continued attractiveness of contracted renewable infrastructure investments that offer stable cash flows while supporting long-term decarbonisation objectives.
Institutional investors are increasingly allocating capital toward infrastructure that combines predictable returns with environmental, social, and governance (ESG) objectives as demand for sustainable investments continues expanding globally.
Portfolio Already Includes Major Projects
Quinbrook said the fund’s investment portfolio is already well advanced, with several large-scale renewable energy projects already under development.
Among the fund’s largest investments is the 373 MW Mallard Pass Solar Project in England’s East Midlands, one of the country’s significant utility-scale solar developments.
QRIF II has also invested in Aegis Energy, a clean energy refuelling platform supporting low-carbon transport infrastructure, and Project Norton, a renewable energy project in Stockton-on-Tees combining 65 megawatts of solar power with 41 megawatts of battery storage.
Together, these investments are expected to increase renewable electricity generation while strengthening electricity grid reliability through expanded energy storage capacity.

Expanding into New Energy Transition Sectors
Quinbrook said the second fund broadens its investment strategy beyond renewable power generation into sectors expected to play a growing role in the energy transition.
In addition to solar and battery storage, QRIF II will target investments supporting grid stability infrastructure in Ireland and the decarbonisation of commercial transport across the UK.
According to Keith Gains, Managing Director and UK Regional Lead at Quinbrook, investor demand continues growing for infrastructure capable of simultaneously improving energy resilience and reducing greenhouse gas emissions.
He said supportive government policies across both countries continue creating attractive long-term investment opportunities in renewable energy infrastructure.
Building on Previous Fund Success
QRIF II follows the successful launch of Quinbrook Renewables Impact Fund I (QRIF I), which closed in October 2023 after raising €620 million.
The strong performance of the second fund demonstrates continued investor confidence in Quinbrook’s renewable infrastructure strategy and reflects broader market demand for assets supporting energy transition and climate objectives.
As governments accelerate investments in clean electricity systems, renewable infrastructure funds are increasingly becoming an important source of capital for large-scale energy projects that contribute to emissions reductions while improving long-term energy security.
Outlook
Quinbrook’s successful fundraising highlights the growing role of private capital in financing Europe’s energy transition. As the UK and Ireland continue investing in renewable electricity generation, battery storage, grid modernisation, and transport decarbonisation, institutional investors are expected to increase allocations toward infrastructure assets offering stable long-term returns and measurable environmental impact. With QRIF II already deploying capital into major renewable energy projects, the fund is well positioned to support regional decarbonisation goals while strengthening energy resilience and expanding clean infrastructure across both markets.
