Coryton BESS

11MW/22MWh Coryton BESS

Coryton Battery Energy Storage System (BESS) is an 11MW/22MWh energy storage project located at Coryton Energy Park in Corringham, Essex, UK. Developed by Root-Power, a subsidiary of the YLEM Group, the project commenced construction in May 2024 and is expected to become operational in mid-2025. The system utilises SolBank energy storage solutions supplied by Canadian Solar's e-STORAGE division. SolBank features high-density lithium-iron-phosphate (LFP) cells, an active Battery Management System (BMS), and an innovative liquid cooling Thermal Management System (TMS).

Coryton BESS is designed to store and release energy as needed, enhancing grid stability and supporting the integration of renewable energy sources. The site is located at London Gateway, a deep-water port on the River Thames’ North Bank. It was strategically chosen for its proximity to the UK Power Networks' Coryton South substation, facilitating a cost-effective and straightforward grid connection.

Wilson Power Solutions contributed to this project by delivering and installing a 10MVA 33/11.5kV Wilson Power Transformer and two 500kVA 11500/433V Wilson Auxiliary Transformers. The grid transformer is fitted with a number of ancillaries for monitoring, an HV on-load tap changer (OLTC) for voltage regulation, and an AVR wall-mounted panel for automated and remote operation.

These transformers provide a stable grid connection while ensuring a reliable and efficient power conversion. As the demand for energy storage grows, our advanced transformer technology continues to support the expansion of grid-scale renewable projects across the UK.
