In Europe, 2025 can be seen as the year of algorithmic traders and specialist firms providing advanced trading and dispatch capabilities. The three leading players, Entrix, Enspired, and Capalo Al, accounted for approximately 75% ofthe 3.4 GW of third-party standalone BESS merchant optimization agreements disclosed in 2025 across Europe, excluding GB. That said, algorithmic traders are not the only players in this space. Utilities such as Axpo, Engie, and Eneco also offer optimization agreements on a fully merchant basis, often structured over longer tenors. than pursuing rapid expansion, these players have now focused on consolidating their positions and strengthening performance track records. The GB BESS optimization landscape remains highly competitive, with utilities (EDF and Statkraft are leading the pack), commodity traders, and oil majors also active in merchant optimization alongside algo-traders. Competition has intensified further with the presence of Tesla, which combines utility-scale BEsS hardware with proprietary dispatch and Due to limited balance sheet capacity, algorithmic traders are typically unable to offer guaranteed grade counterparties, including utilities and commodity traders, to gain access to the FPA market.
