The Transmission Company of Nigeria Plc (TCN) has demanded for a review of the current electricity tariff, ostensibly cost reflective tariff which will entail more payment by the end users of power.

TCN demand was contained in an application filed to the Nigerian Electricity Regulatory Commission (NERC) for an extraordinary tariff review as a means of ensuring that generation companies are incentivized to provide sufficient spinning reserves and other ancillary services that are critical for managing the national grid.
TCN and NERC are federal government wholly owned agencies in the power sector. Before now, Distribution Companies had been at the forefront of agitation for review and increase of electricity tariff while consumers are opposed to it due to the prevailing power outages.

TCN’s demand follows total System Collapse recorded on September 28, 2017 at 8.03 pm.

A statement by the TCN General Manager, Public Affairs, Ndidi Mbah, explained that reports
obtained from Stations and the sequence of events generated by the SCADA system indicated that the system collapse was triggered by the tripping of Egbin Units ST4, ST6 and ST5 at 20:03:15, 20:03:32 and 20:03:34, respectively.

She said the incident, caused the Nigerian electric power grid to lost generation completely before restoration commenced at 8:22 pm.

According to the statement, ” A post mortem analysis of the event indicated that grid generation was curtailed (to about 4,262.7MW) prior to the inception of the disturbance due to capacity under-utilization and the operational capability required to maintain grid
stability had waned, leaving the system vulnerable to the extent that perturbations of this magnitude resulted in severe system frequency dip that culminated in system collapse.

Mrs Mbah noted that the analysis clearly indicated that there was insufficient level of spinning reserve provided by grid-connected generation companies arising from low tariffs for providing ancillary services.

Further, she said in order to avert such incidence on a sustainable basis, the TCN has filed an application to the Nigerian Electricity Regulatory Commission for an extraordinary tariff review as a means of ensuring that generation companies are incentivized to provide sufficient spinning reserves and
other ancillary services that are critical for managing the national grid.

The Commission solicited for the understanding of all Nigerians as it continued with the efforts to provide the electricity industry with a world class national grid.

She assured that TCN would strive to ensure that the stride attained recently in frequency control is sustained in line with world industry standards and codes.
