Electricity Tariff in Nigeria: Number of Hours To Consume 1 Kilowatt


There is so much fuss about the recent announcement about the hike in electricity tariff for areas that enjoy a minimum of 20 hours of power supply per day (BAND A) while other areas struggle to get two hours of interrupted power supply in 24 hours.

The old tariff for BAND A was N68, they will now be charged N225 per unit. The jack-up in the tariff is backed by the Nigerian Electricity Regulatory Commission (NERC) and was made public on Wednesday, April 3, 2024

Here is everything you need to know about the new tariff, including the consumption rate of your appliances and the minimum number of hours based on your service band.

Factors that affect energy consumption

Alleged manipulation by pre-paid meter:

There are allegations of manipulation of the reading of the prepaid meter among officials of the distribution companies.

So, the consumption rate may be higher in a meter that disco has adjusted to suit its profit margin. For instance, a medium refrigerator that ordinarily consumes 1 unit for 10 hours, may finish within five hours.


Some users on the band A service complain that they rarely have 20 hours of power per day. For instance, Jabi area of Abuja, which is in band A doesn’t get up to 12 hours of power per day. If you fall in this category, the rate of energy consumption may be lower.

The energy consumption rate of appliances

If you use the old fashioned bulb that is 120 watts, your unit will deplete higher than the 15watts electric bulb.
