Local context — Thurrock
Thurrock's Thames Freeport designation provides a unique commercial solar opportunity. For a typical £1.5m PV project within the Freeport zone, the additional ECA provides £375,000 of further year-one tax relief on top of standard AIA — bringing net cash payback under 3 years. The combination of port logistics scale (typical 300,000-1,000,000 sqft buildings) plus Freeport tax treatment plus customer Scope 3 mandates produces the strongest economic case in UK warehouse PV.
