What Infinis Energy does
Infinis Energy is a UK low-carbon power generator that captures methane from landfill sites and disused coal mines and converts it into renewable electricity via gas engines. The company operates the largest fleet of landfill-gas and mineral-methane generation assets in the UK, spanning more than 100 baseload sites that together generate over 1 million MWh per year and prevent more than 5 million tonnes CO2-equivalent annually. In addition to its baseload methane business, Infinis has built a portfolio of flexible power response assets under STOR and capacity market contracts with National Grid, and is actively scaling a solar PV and battery energy storage system (BESS) pipeline, with 257MW of solar under construction and a stated 1GW target for new solar and battery projects.
Infinis monetises generation through four channels: long-dated 10-15 year Corporate PPAs and behind-the-meter private wire connections to enterprise buyers (including Arla Foods, Tata Chemicals Europe, and ENGIE); Contracts for Difference (CfD) allocations secured via UK government auctions; revenue from National Grid capacity market and STOR contracts; and wholesale electricity sales into the grid. Land leasing partnerships with landfill operators (e.g., FCC Environment) and landowners underpin development access. An in-house development team of 20+ professionals and a Centre of Excellence in Morecambe employing 25 specialist engineers support end-to-end project delivery and engine overhaul capability.
The company is a private subsidiary wholly owned by 3i Infrastructure plc, a UK-listed infrastructure investor. In October 2025 it secured a £391 million expanded debt financing package from nine lenders to fund continued growth. Recent strategic priorities include green hydrogen production via electrolysis and battery storage co-located with solar, positioning Infinis as a multi-technology renewable platform built on long-term contracted cash flows.

Infinis Energy product offering
Product offeringCore offering
Infinis is a UK low-carbon renewable power generator that captures methane from over 110 landfill sites and disused coal mines and converts it into baseload electricity through engine combustion. The portfolio also spans utility-scale solar PV, lithium-ion battery energy storage systems (BESS), and emerging green hydrogen production, with all output sold through long-term Power Purchase Agreements (PPAs), Contracts for Difference (CfD), and National Grid capacity market contracts to corporate, industrial and utility buyers.
Product overview
Infinis Energy is a low-carbon energy generator operating as a portfolio of interconnected renewable energy products rather than a single unified platform. The core offering centers on captured methane from landfill gas and disused mines (representing baseload renewable generation), supplemented by flexible power response services for grid support. The company has expanded into utility-scale solar power and battery energy storage systems (BESS), with emerging green hydrogen projects in development. These generation assets are bundled with Power Purchase Agreement (PPA) services—including corporate PPAs and behind-the-meter private wire connections—to offer complete renewable energy supply solutions to corporate and industrial buyers. Land leasing partnerships enable development on challenging sites. The portfolio spans baseload (methane capture), intermittent (solar), flexible (power response, battery storage), and emerging (hydrogen) technologies, all tied together through long-term energy offtake agreements.

Products and services
- Captured Methane from Landfill Gas Baseload renewable electricity generated by capturing methane from landfill sites and combusting it through gas engines; deployed across more than 100 UK landfill sites, processing over 250,000 tonnes of methane annually. Customers are UK electricity buyers procuring renewable power via PPAs and the national grid.
- Captured Mineral Methane Baseload or seasonal renewable electricity generated by capturing methane from disused coal mines through gas wells and piping the gas into engine generators. Suitable for utility PPAs and capacity market contracts.
- Solar Power Utility-scale solar PV generation using ground-mounted panels on fixed-tilt or tracker structures, developed on landfill, brownfield and agricultural land across the UK. Sold under long-term PPAs to corporate and utility buyers, with 257MW under construction as of 2025 and a 1GW strategic target.
- Battery Energy Storage Systems (BESS) Grid-scale lithium-ion battery storage systems ranging from 5MW to 100MW per site with 1.5 to 2 hour duration, available as standalone assets or co-located with solar. Provides flexibility services to National Grid and stores low-cost renewable energy for later discharge.
- Power Response Services Flexible standby power generation assets kept on standby to provide backup electricity to the National Grid during peak demand or low generation events. All sites have contracts under the Capacity Market and STOR schemes with National Grid Electricity System Operator.
- Green Hydrogen Production Green hydrogen produced via renewable-powered electrolysis for industrial and transport applications, intended to displace natural gas use. Emerging capability being explored within Infinis's renewable portfolio.
- Power Purchase Agreements (PPAs) Long-term 10-15 year electricity supply contracts providing baseload or intermittent renewable power to corporate, industrial and utility buyers at fixed or wholesale-indexed prices, including Renewable Energy Certificates and ESG/sustainability reporting benefits.
- Behind-the-Meter PPAs Private wire connections from Infinis generation assets to nearby businesses, bypassing the national grid and avoiding transmission network charges.
