Nigerians face soaring electricity bills if the government goes ahead with plans to scrap its subsidy for 15% of consumers.
Doing so would save the public purse $2.6bn (£2bn) but only heap more pressure on millions of people struggling under a cost-of-living crisis.
The move was announced by presidential spokesperson Bayo Onanuga on Tuesday, as a way to ease pressure on public finances.
He did not say when the rate would go up, but said rates had last been reviewed in 2020.
