Temporis Capital, Clarke Energy, and Trina Storage have announced the start of construction on a 50MW/100MWh Battery Energy Storage System (BESS) in Boat of Garten, Scottish Highlands.

Clarke Energy will act as the EPC contractor, while Trina Storage will supply the BESS system, including its Elementa solution. The project is expected to be operational in Q1 2026 and will provide essential grid balancing and stability services to the Scottish electricity network.

Clarke Energy will also provide a 16-year full O&M agreement, ensuring the long-term performance of the BESS. Trina Storage will offer performance guarantees for the Elementa units throughout the project's lifespan.

The project, developed by Gigabox Developments, is committed to biodiversity net gain and includes a comprehensive landscape planting plan to establish new trees, shrubs, and wildflowers. Gigabox will retain a minority stake in the project.
