Trina Storage, the energy-storage division of Chinese solar systems manufacturer Trinasolar, has signed a Memorandum of Understanding (MoU) with United Kingdom-based Pacific Green Energy Group to deliver up to 5 GWh of grid-scale battery energy-storage systems (BESS) between 2026 and 2028.
When completed, the projects will store and dispatch up to five billion W/h into the grid, utilising Trina Storage modular battery systems, integrating proprietary cell technology and long-duration performance features.
Pacific Green, which has 7 GWh pipeline in Australia, will oversee project development and delivery across multiple Australian sites, expanding on the two companies’ existing partnership at the Limestone Coast North Energy Park (250 MW / 500 MWh) in South Australia.

Pacific Green Chief Executive Officer Scott Poulter said the partnership enables the company to deliver a growing global pipeline efficiently and at scale.
“Together, we’re accelerating the deployment of projects that support the clean energy transition.”
