There are rolling blackouts in Niger’s capital, Niamey, as well as the other major cities of Maradi and Zinder.
People have power supplies for about an hour at a time and then the power goes off for four or five hours.
The Niger electricity company, Nigelec, says this is a result of Nigeria cutting supplies as part of sanctions imposed by the West African bloc, Ecowas, over the coup.
Nigeria is the major supplier of electricity to Niger. Its Transmission Company of Nigeria has declined to comment.
But an anonymous source says a supply to Niger was cut on Tuesday following presidential directives.
