Battery Energy Storage Systems (BESS)
Reliable Battery Energy Storage Systems for solar, storage, and grid connection projects.
Delivering Utility-Scale Battery Energy Storage Solutions
Battery Energy Storage Systems (BESS) are a critical enabler of the UK’s transition to renewable energy. They store electricity when generation is high and release it when demand peaks, balancing the grid, improving resilience, and unlocking greater value from renewable generation assets.
Shawton Utilities specialises in delivering utility-scale BESS projects, providing end-to-end services from design and engineering to installation, grid connection, and commissioning.
