Common questions — cold storage in Grimsby
Why is Grimsby cold storage the best commercial solar economics in the UK?
Five factors stack uniquely at Grimsby: (1) Humber Freeport ECA — 100% ECA on qualifying capex; (2) IETF 30-50% capital grants for seafood and frozen food processing; (3) Northern Powergrid fastest UK G99 at 4-6 months; (4) East coast irradiance 1,000-1,050 kWh/kWp/yr; (5) 94-98% self-consumption from blast freeze 24/7 compressor load. Each factor alone improves payback. Combined, they produce paybacks unmatched anywhere in the UK.
