Protecting Nigeria's cold chain: powering freezers through outages

Cold-chain losses rarely show up as a power bill — they show up as spoiled stock weeks later. In Nigeria, the risk is multiplied by feeder interruptions, voltage dips, national-grid collapses and the cost of keeping a diesel set warm for every outage.

Size for surge, not just for running load

A compressor can pull three to six times its running current for a second or two. Your generator must absorb that without tripping, which is why peak-power rating matters as much as kilowatt-hours for Lagos depots, Abuja clinics and coastal cold rooms.

Size storage for your worst realistic outage

Take the longest outage you saw in the last twelve months, add a margin, and make sure storage covers the cold rooms alone for that period. Non-critical circuits can be left off the protected side so the battery protects what earns or preserves value.

Watch ambient temperature

Ventilation and shade extend both battery life and compressor efficiency. In Lagos and Port Harcourt humidity, siting the unit well is not cosmetic — it changes the payback and protects battery life.
