Stonepeak has announced an equity investment in AMPYR Distributed Energy (ADE). ADE, launched with AGP in 2024, develops, owns and operates onsite renewable energy infrastructure for commercial and industrial customers across the UK and Europe. AGP will retain an interest in ADE following the transaction. Furthermore, ADE has a pipeline of over 1 GW and has contracted 250 MW renewable energy projects across 200 sites till date. The transaction is expected to close in the upcoming days.
In December 2025, Stonepeak acquired a 43.8 per cent stake in Repsol’s Outpost solar project in Texas for $252.5 million. The project, with an installed capacity of 629 MW, began commercial operations in August 2025 and has a valuation of approximately $775 million, including tax equity proceeds. The transaction marks the second US renewables partnership between Repsol and Stonepeak.
In December 2025, AMPYR Distributed Energy (ADE), part of AGP Group, secured a £50 million mezzanine financing facility to support its acquisitions and project funding activities in the UK’s commercial and industrial renewables market. The capital can be utilised across development, construction, and operational stages for both solar and battery energy storage system projects.
