NERC Service Based Tariff Bands
Domestic grid supply in Nigeria is classified into service bands based on daily power availability metrics.
Band A Framework
Guarantees a minimum of 20 hours of daily supply. While offering high stability, it carries the highest tariff per kilowatt-hour, demanding strict consumption audits.
Band B & C Ratios
Band B (16+ hours) and Band C (12+ hours) feature moderate tariffs but exhibit regular price fluctuations, requiring optimized appliance schedules.
Standby Generator Offsets
Low-tier bands (D & E) require standby thermal generation. Factoring in diesel or fuel consumption costs significantly inflates total monthly household overheads.

Domestic Water Conservation & Pumping Costs
Pumping private borehole water draws heavy starting currents from generators or grid meters.
Borehole Start-Stop Load
Electric submersible pumps draw high surge currents during startup. Consolidating pumping schedules (pumping once to fill the tank fully rather than multiple short cycles) reduces starting currents and lowers bills.
Gravity-Fed Systems
Utilizing high-elevation overhead tanks allows gravity to distribute water to household plumbing grid points without drawing constant pressure pump power, capping energy waste.
