The national mightiness grid has suffered a full organisation collapse, resulting inwards temporary loss of electricity generation.
The Transmission Company of Nigeria (TCN), which announced the grid collapse, said inwards a contestation on Fri that the grid “recorded the full organisation collapse on September 28, 2017 at 20:03Hrs.”
TCN said that reports obtained from mightiness stations as well as the sequence of events generated yesteryear the Supervisory Control as well as Data Acquisition (SCADA) had revealed the campaign of the collapse.

“By this incident, the Nigerian electrical mightiness grid lost generation completely earlier restoration commenced at 20:22Hrs.
“A post-mortem analysis of the lawsuit indicated that grid generation was curtailed (to near 4,262.7MW) prior to the inception of the disturbance due to capacity under-utilization as well as the operational capability required to keep grid stability had waned, leaving the organisation vulnerable to the extent that perturbations of this magnitude resulted inwards severe organisation frequency dip that culminated inwards organisation collapse.
“The analysis clearly indicated that in that place was an insufficient score of spinning reserve provided yesteryear grid-connected generation companies arising from depression tariffs for providing ancillary services.
“In lodge to avert such incidence on a sustainable basis, the Transmission Company of Nigeria Plc has filed an application to the Nigerian Electricity Regulatory Commission for an extraordinary tariff review equally a way of ensuring that generation companies are incentivized to render sufficient spinning reserves as well as other ancillary services that are critical for managing the national grid.

On our part, nosotros volition strive to ensure that the measuring attained lately inwards frequency command is sustained inwards draw of piece of job amongst Blue Planet manufacture standards as well as codes.,“ the contestation farther stated.
