Food manufacturing IETF eligibility and rates
IETF Phase 3/4 covers a wide range of food manufacturing processes. Key rates by sector: Bakery (large industrial — Allied Bakeries, Hovis, Warburtons scale): 20-25%. Beverage (carbonated, brewing, distilling — Diageo, Heineken, Coca-Cola supply scale): 25-35%. Dairy processing (pasteurisation, homogenisation, UHT — Arla, Müller, Yeo Valley scale): 25-30%. Frozen food (blanching, IQF freezing, cold chain manufacturing — Birds Eye, McCain scale): 30-40%. Fresh produce packing (MAP packing, washing, chilling): 20-25%. Poultry processing (Moy Park, 2 Sisters scale): 25-30%. Eligibility requires: significant on-site energy-intensive processing; capital investment decision; 5+ year commitment to the site. We assess eligibility at free desk feasibility.
Self-consumption economics: why food manufacturing solar is outstanding
Food manufacturing sites have continuous high-power electrical loads: refrigeration and cold chain plant (24/7); processing machinery (mixing, extrusion, forming, slicing — 16-24 hours/day); compressed air (continuous); HVAC (year-round); conveyor and automation systems. Self-consumption: frozen food manufacturing: 90-96%; dairy: 88-94%; bakery: 82-88%; beverage: 80-87%; fresh produce: 85-92%. At 90%+ self-consumption, every kWh of solar generation directly displaces grid electricity at retail rate — maximising the cash saving and minimising the payback period. With IETF, bakery paybacks can reach 2-3 years; frozen food 1.5-2.5 years.
BRC and GFSI hygiene-compliant solar installation
Food manufacturing warehouses holding BRC Global Standard for Storage and Distribution (v9) or GFSI-benchmarked accreditation (SQF, IFS, FSSC 22000) require that any structural or roof works are conducted without compromising product safety or food hygiene. Our food manufacturing installation methodology: sealed access with positive-pressure airlock where required; HEPA-filtered work zones for allergen-sensitive sites; contractor food hygiene training (BRC Global Standard clause 2.9.1 compliance); installation phased around production schedules; no overhead work above open product lines during installation; MCS documentation cross-referenced to BRC audit trail. We have installed on active BRC AA* sites without any audit findings.
EV refrigerated fleet charging: the food logistics solar opportunity
Major grocery logistics operators (Wincanton, XPO, CEVA, Tesco Distribution) are deploying electric refrigerated vehicles (Volta Zero, Tevva, DAF CF Electric) from 2024-2027. Refrigerated EV charging has an extraordinary self-consumption profile — daytime charging (depot returns between routes) combined with continuous cold chain baseload can push self-consumption above 95%. We design EV charging infrastructure alongside PV for food logistics depots. Typical food logistics depot: 200-800 kW PV + 6-24 EV charge points.
Common questions
What IETF rate applies to bakery manufacturing?
Large industrial bakery operations (Allied Bakeries, Hovis, Warburtons, Roberts Bakery scale) qualify for IETF Phase 3/4 at 20-25%. Smaller craft bakeries may also qualify if energy-intensive process equipment (deck ovens, spiral mixers, proving chambers) is in use and capital investment criteria are met. We assess IETF eligibility at free desk feasibility for all food manufacturing enquiries.
Can solar be installed on an active BRC-accredited food site?
Yes — we have installed on active BRC AA* and SQF-certified food manufacturing sites without any audit findings. Our food hygiene-compliant installation methodology covers sealed access, HEPA filtration, contractor food training, and MCS documentation cross-referenced to BRC clause 2.9.1. We provide a pre-install site safety plan for QA/Technical director sign-off.
