Kent’s Cleve Hill Solar Park, expected to become the UK’s largest, comprises 373 MW of solar PV alongside 150 MW of battery storage (with potential for 700 MWh capacity). This hybrid national infrastructure project can shape regional power markets, supplying London and supporting offshore wind balancing via its big 400 kV substation connection.
Cleve Hill demonstrates how solar-plus-storage at scale can deliver dispatchable power and grid support. It also reveals how infrastructure at this scale involves major environmental, planning and community engagement commitments and offers development templates adaptable for commercial sectors.
For Crucial Energy, Cleve Hill acts as a benchmark. While not replicable at the same scale, its integration model (PV + storage + substation-led export) shows pathways for industrial clients with heavy loads or balancing needs.
