CleanPeak Energy agreed to acquire 100% of Sustainable Energy Infrastructure (SEI), expanding its distributed renewable portfolio across Australia. The deal adds 71 MWac of solar capacity and 42 MW of battery storage systems across New South Wales, Victoria and South Australia. The acquisition strengthens CleanPeak’s retail growth strategy, renewable energy footprint and distributed solar-plus-storage capabilities.
PROJECT SNAPSHOT
Project: Distributed solar and battery portfolio (SEI acquisition)
Capacity: 71 MWac solar, 42 MW battery storage
Technology: Solar PV + battery energy storage systems (BESS)
Scale: 16 solar sites, 11 battery locations
Location: New South Wales, Victoria, South Australia, Australia
Application: In-front-of-the-meter, distributed energy systems
Timeline: Within 3–5 year expansion plan
Objective: Portfolio expansion, improved energy management, multi-state grid integration
CleanPeak Energy completes its purchase of Sustainable Energy Infrastructure (SEI), adding a diverse collection of solar and battery storage systems throughout Australia. The acquisition expands CleanPeak’s portfolio in New South Wales, Victoria and South Australia by adding approximately 71 MWac of solar power from 16 sites and 42 MW of battery capacity across 11 locations.
Primarily SEI’s portfolio consists of smaller-scale projects under 5 MW, structured as distributed energy systems connected to local networks. With the integration of these assets, CleanPeak increases its exposure to in-front-of-the-meter operations. Here electricity is supplied directly to the grid or end users rather than confined to on-site consumption. This shift supports broader and active participation in wholesale and retail energy markets.
The inclusion of battery storage systems across the portfolio enables improved energy management and allows stored electricity to be dispatched during periods of higher demand. This supports load balancing and enhances operational control across geographically dispersed assets. The combination of solar generation with battery storage also allows for better alignment between generation profiles and consumption patterns.
The geographic spread of the assets across three states provides diversification in generation and demand conditions. This distribution reduces dependency on a single network or region and enables more consistent performance across varying grid conditions. It also supports energy supply continuity by balancing output fluctuations between locations.
The acquisition aligns with CleanPeak’s 3 to 5year plan to expand its distributed energy and grid-facing portfolio. CleanPeak’s efficient operating model, robust risk management approach, and demonstrated expertise in battery development enable the company to maximise output from its solar and BESS portfolio while creating additional value through future battery expansion.
CleanPeak, established in 2017, has developed a portfolio focused on distributed energy infrastructure, including solar installations, battery systems, and integrated energy solutions for commercial and industrial users. The addition of SEI’s assets extends this portfolio and increases the company’s capacity to deliver electricity across multiple market segments.
The transaction was supported by Gresham Partners as financial advisor and Maddocks as legal counsel. With the acquisition completed, CleanPeak is positioned to scale its operations in response to increasing demand from commercial customers and government-backed energy programs across Australia.
