Northampton is the Golden Triangle's most active DC solar market — Amazon, ASOS, TK Maxx and major 3PLs all operate large DCs with active Scope 3 mandates.
Northampton solar economics
Irradiance 970-1,000 kWh/kWp/yr. Grid retail 22p/kWh. WPD G99: 5-7 months NN postcodes. DC payback: 5-6yr. FC payback: 4.5-5.5yr. Self-consumption logistics: 76-82%.
Golden Triangle DC campus
Amazon FCs at NN4 and NN10 (Amazon Climate Pledge active — on-site verified generation required). ASOS NN10 (Fashion with Integrity). TK Maxx NDC (NN5). Wincanton, DHL Northampton hubs. NN10 A45/A6 corridor is the highest-density PV opportunity.
Amazon Climate Pledge requirement
Since 2024, Amazon requires on-site verified solar generation (not just PPA) at Prime FC locations. Scope 3 mandate flows through 3PL supply chains operating at Northampton. We deliver Amazon audit packs as standard.
WPD G99 at Brackmills
Brackmills (NN4) — pre-application engagement with WPD recommended for systems above 1.5 MW. NN10 (East Northants): standard 5-7 month G99. G99 submitted same-week as structural survey.
