The Transmission Company of Nigeria (TCN) managed grid went down at approximately 11:51 AM on Sunday, reducing the system’s capacity from 2,407 megawatts to a mere 31MW by noon and reaching zero by 1 PM.
Despite the Federal Government privatizing the sector over eleven years ago, the grid remains unreliable, failing consumers on more than 141 occasions.
