Norfolk and Suffolk are home to one of the UK's most IETF-eligible cold storage and food processing clusters. Key operations: Bernard Matthews (Halesworth, Holton — the UK's largest turkey producer, blast freeze, chilled processing, IETF-eligible); Cranswick Norfolk (Watton — pork and poultry processing, IETF-eligible); Greencore (East Anglian ready meals — IETF-eligible); and a network of chilled produce 3PL operators serving Norwich, Ipswich, and Cambridge markets. East of England irradiance (1,000-1,055 kWh/kWp/yr) and UKPN fast G99 (4-6 months) combine to make Norfolk cold chain solar some of the best-returning in England.
Local context — Norwich
Norfolk cold chain solar economics: (1) East of England irradiance advantage (1,000-1,055 kWh/kWp/yr versus 940-975 kWh/kWp/yr in the Midlands); (2) UKPN fast G99 (4-6 months); (3) IETF 30-50% capital grants for food processing cold chain; (4) 24/7 food processing baseload (Bernard Matthews, Cranswick): 90-96% self-consumption. Combined after-grant, after-tax payback: 2.5-3.5 years for IETF-eligible Norfolk food processors.
Recent install — Norwich

Self-consumption 94% (24/7 blast freeze and chilled processing). Annual saving £124,000. IETF at 38%: £91k grant. UKPN G99: 5 months. After-grant payback: 3.0 years; 25-year IRR 28%.
Common questions — cold storage in Norwich
Is Bernard Matthews Norfolk IETF-eligible?
Yes. Bernard Matthews turkey processing (blast freeze, chilled further processing, cooked products) is IETF-eligible food processing. We have supported IETF applications for poultry processing operations. Intervention rate for turkey processing: typically 35-45%.
What irradiance advantage does Norfolk have for commercial solar?
Norfolk averages 1,020-1,055 kWh/kWp/yr — among the UK's highest commercial irradiance for inland sites. Norfolk irradiance advantage versus the Midlands: 5-10%, worth approximately £8,000-£15,000/year in additional savings on a 1 MW system versus equivalent Birmingham install.
