A viral Nigerian post cited the Rural Electrification Agency: tens of thousands of communities have no pole or transformer. Roughly 85 million Nigerians lack grid power — the world's largest access gap. Here's the actual engineering decision, village by village.
Drag to rotate the village. Pick a solution and watch the infrastructure — and the lit homes — change.
String poles and wire from the nearest line, add a transformer. Unbeatable power quality — but cost scales with distance (~$15–25K per km of medium-voltage line), so remote villages price out fast.
A village-scale solar array + battery bank + local distribution. Nigeria's REA and the World Bank have funded hundreds. Typically $500–1,000 per connection; powers fridges, mills, welders.
Per-house panel + battery kits (often pay-as-you-go by phone). Cheapest entry (~$100–300) and instant — but runs lights, phones and a TV, not machines. A bridge, not a destination.
