Bilston sits at the heart of the Black Country automotive supply chain serving JLR Solihull, BMW and Stellantis. Two-shift press shops, heat treatment, casting and injection moulding operations achieve self-consumption above 85% — compressing solar paybacks to 4-5 years. IETF Phase 3 grants of 30-50% are available for manufacturers above 1 GWh/year. WMCA net zero 2041 and JLR Scope 3 requirements by 2030 make solar adoption urgent for Black Country Tier 1-2 suppliers.
Local context — Bilston
The Bilston and Wednesbury area industrial estate network hosts precision engineering, pressings, castings and automotive components with electricity bills of £300,000-£1.5m/year. WPD/NGED Bilston (WV14) substation has benefited from grid investment associated with JLR EV expansion. The West Midlands Combined Authority (WMCA) Business Growth Programme provides additional co-investment for qualifying Black Country SME decarbonisation projects.

Modelled scenario — Bilston
A 500 kW solar PV install on a 120,000 sqft press shop at Bilston, supplying body pressings to a JLR Tier 1 assembler. Two-shift Monday-Saturday operation achieves 88% self-consumption. Annual generation 435,000-460,000 kWh. Annual savings: £96,000-£115,000. IETF grant (38% of £400,000 capex): £152,000. Effective post-grant cost: £248,000. AIA relief (25% corp tax on £248,000 net): additional £62,000 year-one. Net effective investment: £186,000. Payback: 2.3-2.8 years on net basis.
Common questions — manufacturing in Bilston
Can Bilston automotive manufacturers get IETF grants for solar?
Yes — most medium-large Black Country press shops, heat treatment and casting businesses consume more than 1 GWh/year and qualify for IETF Phase 3 grants of 30-50%. Combined with 100% AIA, net effective project cost can be reduced to 25-40% of gross cost.
What self-consumption ratio do Black Country automotive manufacturers achieve?
Two-shift operations (6am-10pm) typically achieve 82-90% self-consumption. Continuous three-shift operations (press shops, heat treatment) achieve 88-93%. Single-shift operations achieve 60-70%. Higher self-consumption = faster payback.
