Pharmaceutical warehouses have among the highest self-consumption rates of any UK commercial property — 24/7 refrigeration plant (2-8°C licensed cold chain), clean room HVAC, and serialisation create a continuous electricity baseload that absorbs 90-96% of daytime PV generation. This makes pharmaceutical warehouse solar one of the strongest commercial PV investments available, with paybacks of 4-4.5 years before IETF grants.
GDP compliance: the key questions answered
GDP (Good Distribution Practice) covers pharmaceutical wholesale and distribution of medicinal products. Solar PV is fully GDP-compatible because: (1) solar PV supplements mains power — cold chain continues on mains supply and solar reduces import costs; (2) installation methodology can be designed for zero contamination risk (sealed access protocols, no roof penetrations over product zones, HEPA filtering); (3) solar monitoring is a separate system from GDP environmental monitoring — no cross-system dependency.
We provide GDP installation documentation at handover: installation qualification (IQ), operational qualification (OQ), and post-installation QC documentation for your GDP audit file.
Cold chain self-consumption: why 90-96% matters
24/7 refrigeration from 2-8°C licensed cold rooms creates a continuous electricity baseload of 200-400 kW for a typical 10,000-pallet WDA facility. PV sizing: 400-600 kW optimal for 90-96% self-consumption. At 94% self-consumption: a 500 kW system displaces 470 kW of grid import — worth £131,600/year at 28p/kWh. Simple payback: 4-4.5 years. After-tax (100% AIA): 3-3.5 years.
IETF for pharmaceutical manufacturers
IETF covers pharmaceutical manufacturing (sterile fill-and-finish, solid-dose, API synthesis, lyophilisation). Pharmaceutical manufacturer warehouses connected to manufacturing processes are IETF-eligible. Standalone WDA-only licensed wholesalers (no manufacturing) are not IETF-eligible. Intervention rate: 30-50%. Maximum award £10m. We confirm eligibility and support applications.
