HENCEFORTH, before any outage, consumers will be told in advance so that they can be prepared for it, according to the Nigerian Electricity Regulatory Commission (NERC).

But there is a proviso: Such a notice will only be given when there are scheduled power supply interruptions which the nation’s distribution companies have control over.

Nigeria and cant take off projects  - we no dey tire at all -

In my area they take electricity so rapid that an advance notification will be useless.
