Portsmouth and South Hampshire host a distinct commercial solar market anchored by: Portsmouth Port (the UK's second-busiest passenger port — QinetiQ, BAE Systems, Babcock International defence operations); Solent Freeport (Portsmouth Port and Tipner Lake designated sites — 100% ECA on qualifying capex); and the M27 logistics corridor (Amazon Havant, DHL Portsmouth, logistics serving the South Coast consumer market). SSEN DNO — G99 5-8 months for Portsmouth and Fareham commercial sites. South Coast irradiance: 1,000-1,060 kWh/kWp/yr.
Solent Freeport Portsmouth — designated sites
Solent Freeport has two Portsmouth-area designated tax sites: Portsmouth Port (HM Naval Base perimeter — commercial port operations, Brittany Ferries terminal, continental goods import/export) and Tipner Lake (planned logistics and marine campus north of M275). Note: the primary Solent Freeport logistics sites (Nursling, Marchwood) are in Southampton — Portsmouth-area designated sites are smaller but still provide 100% ECA on qualifying plant and machinery. We confirm building-level ECA eligibility at desk feasibility.
Defence and maritime manufacturing solar
BAE Systems Portsmouth (Queen Elizabeth carrier support, destroyer maintenance — HMNB Portsmouth). Babcock International (Devonport-adjacent supply chain, Portsmouth naval support). QinetiQ (defence technology, Portsdown Hill). These defence and maritime operators have: (1) Ministry of Defence (MoD) sustainability requirements (MoD operates a net zero programme requiring Scope 3 reduction from defence contractors); (2) IETF eligibility for eligible manufacturing processes; (3) Large industrial buildings on the Portsmouth waterfront. MoD-connected commercial buildings require additional security review for solar installations — we have experience with MoD-adjacent and defence contractor solar.
Portsmouth M27 logistics corridor
The M27/A27 corridor (Portsmouth-Fareham-Eastleigh-Southampton) is the South Coast's primary logistics spine. Key locations: Amazon Havant (M27 J9 — large parcel DC), DHL Portsmouth (Hilsea Industrial Estate), Royal Mail Portsmouth (Quartremaine Road), Tesco South Coast DC (Fareham). SSEN DNO for all M27 corridor sites: 5-8 months G99. South Coast irradiance advantage: 1,000-1,060 kWh/kWp/yr.
