Local context — Southampton
Southampton cold storage solar combines three financial stacks: (1) South Coast irradiance (1,000-1,050 kWh/kWp/yr); (2) Solent Freeport ECA (within designated sites — Marchwood, Nursling); (3) IETF grants (30-50% capital intervention for eligible food import cold chain). 24/7 port logistics cold store baseload: 90-95% self-consumption. SSEN DNO G99: 5-7 months for Southampton port area. Port of Southampton climate ambitions provide additional incentive layer.
