TCN blames low generation for nationwide incessant outages

THE Transmission Company of Nigeria says the current load shedding being experienced nationwide is as a result of very low power generation by the electricity generation companies for the TCN to wheel through the transmission grid to distribution companies nationwide.

For close to three weeks now, power consumers in various locations across the country have been complaining of incessant outages amidst the over one month scarcity of Premium Motor Spirit, popularly called petrol, in Nigeria.

Reacting to the outages in a statement issued in Abuja, the transmission company said, “The media has been awash with reports that TCN has reduced the load allocation to distribution companies. That information is incorrect.

“The correct position is that TCN can only transmit the quantum of power generated by Gencos through the national grid to distribution load centres nationwide.

“For clarity, TCN does not generate electricity and therefore can only transport cumulative generation from all the generation companies nationwide to distribution load centres.”

It stated that the distribution companies were responsible for end-user consumption, while TCN allocated power to Discos based on approved percentage of the total generation available per hour or on day-ahead nomination.

TCN stated that currently, the cumulative generation nationwide was low and Gencos had attributed this to several factors including poor gas supply, fault in generating units, scheduled and unscheduled maintenance.

It said all of these issues had caused most power generating companies to limit their generation, and sometimes not generate at all.

“A summary of the power generating profiles in the last two months, for instance, clearly shows that 14 gas-powered generating stations were either not generating at all or had limited generation at various times within the period, further depleting the quantum of power generation available for transmission into the grid on a daily basis,” TCN stated.

It added, “Power generating stations in this category include Omotosho units 5 & 6, Olorunsogo units 3, 4 & 6, Omoku Units 3 & 6, Omotosho NIPP units 3 & 4, Delta units 15, 17, and 18, Afam VI units 11 & 12, Olorunsogo NIPP unit 3, Ihovbor NIPP unit 2, Sapele Steam unit 3, Sapele NIPP unit 1, Odukpani NIPP units 1 & 3, and Okpai units 11, 12 & 18.

“Also, within the same period, Jebba Hydro and Shiroro Power Generating Stations were either out or had limited generation, causing additional loss of 232MW from the grid.

“Other power generating plants such as  Omotosho units 3&4, Olorunsogo units 1, Delta units 10 &20, Afam VI  unit 13, Ihovbor NIPP units 4, Geregu NIPP units 22&23 and Odukpani NIPP units 2, 4 & 5, have also been out either on fault or for scheduled maintenance, causing a further loss of about 3,180MW from the grid.”

TCN stated that a combination of the above scenarios had persisted and the total effect on the grid was persistent low generation, which operators of the transmission company had strived to dispatch in a way that would not jeopardise the stability of the grid.
