On July 1, 2025, Gelion announced the completion of installation for two 1 MW/2 MWh battery energy storage systems (BESS) at Borg Group sites in Somersby and Charmhaven near Sydney, Australia. The systems have entered advanced commissioning and are expected to begin live operations shortly. This update follows an earlier announcement in April 2025.
Financially, Gelion recognized approximately £900,000 (92.5%) of the contract revenue in its FY2025 results, with the remaining £65,000 deferred to July 2025 (FY2026). Revenue recognition across FY25 and FY26 remains subject to Gelion management’s audit review.
Gelion and Group Energy, the Borg Group’s energy services division, have commenced business case development for larger-scale BESS deployments across additional Borg sites. Meanwhile, Gelion’s overall project pipeline is expanding across multiple sectors, including industrial, consumer, education, and utility companies within the Australian market.
The containerized BESS units are designed to charge during periods of high solar generation and discharge when electricity demand peaks, lowering Borg Group’s energy costs and reducing its peak grid draw. In addition to cost savings, the systems will contribute to grid stability by providing frequency response services, including Very Fast Frequency Control Ancillary Services (VF-FCAS).
John Wood, CEO of Gelion, said “It’s fantastic to see Gelion’s BESS in the final stages of commissioning at Borg’s sites. Our teams have worked very closely together to rapidly progress this important project. It is also exciting for Gelion to be working closely with Group Energy to define their next potential scaled up BESS for the Group while in parallel, our Integration team are growing a healthy pipeline of BESS opportunities in the Australian market.”
John Borg, Managing Director of Borg Group, “Gelion has demonstrated strong integration expertise and capability during the project. Group Energy is looking forward to operating the BESS units which will start delivering the projected electricity cost and sustainability benefits in the near term. As we review and assess the BESS’s operational performance and commercial returns, we will then shore up our plans for additional BESS units to be deployed across our business.”
The Somersby and Charmhaven installations showcase Gelion’s modular, 20-foot containerized approach, which integrates cells, power electronics, and control systems within a single enclosure. This project underscores the increasing role of battery energy storage in managing renewable generation and optimizing energy expenditure for large-scale end users.
