Stonepeak-backed ADE buys Eden Sustainable to turbo-charge UK C&I rooftop solar drive

• ADE acquires Eden Sustainable, adding a 65-MWp rooftop solar pipeline and bolstering its UK C&I offering after closing a £170 m debt facility earlier this week.

London-based AMPYR Distributed Energy (ADE) has moved to scale its behind-the-meter business by acquiring Eden Sustainable Ltd, a fast-growing developer of rooftop solar solutions for commercial and industrial (C&I) customers across Britain. The deal, announced on 2 June 2025, transfers Eden’s 50-strong team and its portfolio of funded power-purchase-agreement (PPA) projects to ADE, part of the Singapore-headquartered AGP Group and majority-financed by US infrastructure investor Stonepeak. Financial terms were not disclosed.

Why Eden?

Founded in 2014, Eden has carved out a niche delivering no-capex rooftop arrays for manufacturers, leisure groups and schools. Revenues have soared at a 123% compound rate over the past three years, hitting £13.5 million in 2024, and the company recently secured a £75 million growth facility from Thrive Renewables. Flagship clients include David Lloyd health clubs and Domino’s Pizza, and its live and advanced pipeline now tops 65 MWp spread across more than 90 sites, according to company filings.

Strategic fit for ADE

ADE was launched in January 2024 with an initial £100 million equity line and has since raised a £170 million construction and term-loan facility with Crédit Agricole CIB. The platform has already contracted 50 MW of solar-plus-storage projects at factories, retail centres and sports stadia, and says Eden will “double the depth” of its addressable market while adding seasoned origination and O&M capability.

John Behan, ADE’s CEO, called the purchase “a step-change that lets us offer corporates a full turnkey service from design through 25-year asset management, at a time when power-price volatility and Scope-2 carbon rules are driving record demand for onsite generation.”

Market context

The UK installed a record 2 GW of commercial rooftop PV in 2024, yet C&I systems still account for under 10 % of national solar capacity. Analysts at Cornwall Insight expect the segment to treble by 2030 as grid-connection hurdles steer investors toward behind-the-meter assets with batteries and fixed-price PPAs. Eden’s existing engineering base in Cambridgeshire will become ADE’s national delivery hub; all 35 live PPAs will continue unchanged.

Stonepeak partner Tracy Goh said the transaction “demonstrates our intent to build a multi-gigawatt distributed-energy platform across Europe,” pointing to AGP’s wider 12-GW renewables pipeline on three continents.

Integration work starts immediately, with Eden co-founder Scott Burrows joining ADE’s executive committee. The combined entity targets 500 MWp of financed UK rooftop solar and 1 GWh of co-located storage by 2028, positioning itself as a one-stop shop for businesses pursuing Net-Zero goals under tightening UK corporate-reporting rules.
