Nigeria loses N8bn monthly to transmission failures
Legit.ng earlier reported that Nigeria’s electricity sector loses between N5 billion and N8 billion every month due to transmission inefficiencies, according to the Managing Director of the Nigerian Independent System Operator (NISO), Abdu Bello.
Bello disclosed this on Wednesday during NISO’s first anniversary event held in Utako, Abuja, where he outlined key reforms and operational progress recorded since the agency was established.
As reported by PUNCH, Bello stated that the operator inherited significant transmission losses at inception, with the loss factor nearing 10 per cent, resulting in substantial financial setbacks for the sector.
