Maddocks has advised CleanPeak Energy Holdings on its agreement to acquire 100 per cent of Sustainable Energy Infrastructure (SEI), an Australian owner and developer of sub‑5MW solar and battery energy storage assets backed by Australian Retirement Trust and CareSuper.  

SEI’s portfolio comprises 71MW of solar capacity across 16 sites, alongside 42MW of battery energy storage systems across 11 sites, in New South Wales, Victoria and South Australia.  

The transaction represents a significant step in CleanPeak’s national growth strategy and further strengthens its position in the distributed and behind‑the‑meter renewable energy market. 

Maddocks advised CleanPeak throughout the transaction, delivering an integrated and commercially focused approach. Partner Ron Smooker commented, 

“The transaction was another illustration of the constantly evolving commercial dynamics of Australia’s energy transition. CleanPeak, as an established operator of renewable assets, needed advisors that would help to quickly identify the material risks and opportunities. Our history working together meant that Maddocks was able to do that.” 

The transaction further demonstrates Maddocks’ deep experience in advising on complex energy and infrastructure acquisitions, particularly in the renewable energy sector, and builds on our strong transactions history with CleanPeak.  

The Maddocks team advising CleanPeak Energy was led by a Commercial Group team including Partner Ron Smooker, Special Counsel Jacquline Picone and Senior Associate Oliver Wahlstrom, and supported by Partners Elizabeth Lilley, Peter Limbers, Sefton Warner, Meaghan Bare, Chong Ming Goh and Wolfgang Hellmann.
