Overview

Infinis is the largest generator of baseload low-carbon electricity from captured methane in the UK and is rapidly transforming through an active solar and battery development pipeline. 

Why we invested

The investment in Infinis is foremost a yield play. Its front-ended cashflows balance other recent investments by the Company in more growth-oriented businesses. Revenues are underpinned by the inflation-linked UK Renewables Obligation Certificate (“ROC”) regime until 2027. 3iN also believed Infinis could become a platform to make new investments in activities such as distributed power generation from other gas sources, distributed energy storage by exploiting the business’s spare engine and grid connection capacity, and additional landfill gas sites. 

Recent developments

Infinis performed ahead of expectations during the year, supported by higher-than-forecast electricity exports from its landfill gas operations. Although gas and power prices moderated through 2025, this trend has since reversed with the supply disruption caused by the conflict in the Middle East expected to benefit the business in the medium term.

Strategically, Infinis is well positioned to scale and diversify its generation portfolio through the development of solar and battery storage projects across its brownfield and landfill estate. These sites benefit from attractive fundamentals, including existing grid connections and relatively short development timelines. Good progress was made during the year, with 20MW of new solar and battery capacity coming online and a further 280MW currently under construction.

The business continues to engage with policymakers regarding potential support for landfill gas beyond the expiry of the Renewable Obligation Certificate subsidy support in April 2027.
