Logistics at the water's edge

Warehousing clustered around a working port rarely operates in isolation. It sits inside a wider estate — quays, cargo handling, cold chain and vehicle movements — that is usually decarbonising as one programme, which is why solar here tends to be wrapped into a corporate PPA spanning several buildings rather than a single roof. Arrays in the 1-3MWp range are common, priced around 9-12 p/kWh, and delivering £140k-£420k in annual savings across the sheds they cover.

A load the port itself amplifies

Port logistics carries demand that inland sites simply don't have. Refrigerated containers plugged into reefer points draw hard and continuously, shore-power and cargo-handling electrification are pushing site loads higher still, and that rising baseload gives daytime generation somewhere to go every hour the sun is up. Where the local grid is already constrained — a frequent story at busy ports — on-site solar also eases the pressure on an import connection that is expensive or slow to upgrade.

• Reefer plug-in points create a heavy, steady daytime load
• Estate-wide programmes suit multi-building corporate offtake
• On-site generation relieves constrained port grid connections

Building for a coastal roof

Exposed waterfront locations bring their own engineering: higher wind loading on the mounting system and marine-grade specification to resist salt corrosion. Neither is a barrier — both simply need designing for from the outset rather than discovering later.
