Nationwide blackout will proceed as GenCos generate little or no electrical energy: TCN

POWER GENERATION AND ONGOING LOAD SHEDDING NATIONWIDE

The Transmission Firm of Nigeria needs to inform customers of electrical energy that the present load shedding being skilled nationwide is because of very low energy technology by the Era Corporations (GENCOs) for TCN to wheel via the transmission grid to distribution corporations nationwide.

The media has been awash with studies that TCN has lowered the load allocation to distribution corporations. That data is wrong. The proper place is that TCN can solely transmit the quantum of energy generated by GenCos via the nationwide grid to distribution load centres nationwide.

For readability, TCN doesn’t generate electrical energy and due to this fact can solely transport cumulative technology from all of the technology corporations nationwide to distribution load centres. The distribution corporations are answerable for end-users consumption. TCN allocates energy to distribution corporations based mostly on authorised proportion (components authorised by NERC), of the overall technology accessible per hour or on day-ahead nomination.

Presently, the cumulative technology nationwide is low and technology corporations have attributed this to a number of components together with poor fuel provide, fault in producing items of producing corporations, scheduled and unscheduled upkeep, all of which have brought on most energy producing corporations to restrict their technology, and generally not generate in any respect.

A abstract of the facility producing profiles within the final two months, for example, clearly exhibits that fourteen (14) fuel powered producing stations have been both not producing in any respect or had restricted technology at numerous instances throughout the interval, additional depleting the quantum of energy technology accessible for transmission into the grid every day. Energy producing stations on this class embody; Omotosho items 5 & 6, Olorunsogo items 3, 4 & 6, Omoku items 3 & 6, Omotosho NIPP items 3 & 4, Delta items 15, 17, and 18, Afam VI items 11 & 12, Olorunsogo NIPP unit 3, Ihovbor NIPP unit 2, Sapele Steam unit 3, Sapele NIPP unit 1, Odukpani NIPP items 1 & 3, and Okpai items 11, 12 & 18.

Additionally, throughout the similar interval, Jebba Hydro and Shiroro Energy Producing Stations have been both out or had restricted technology, inflicting further lack of 232MW from the grid, whereas different energy producing vegetation comparable to Omotosho items 3&4, Olorunsogo items 1, Delta items 10 &20, Afam VI unit 13, Ihovbor NIPP items 4, Geregu NIPP items 22&23 and Odukpani NIPP items 2, 4 & 5, have additionally been out both on fault or for scheduled upkeep, inflicting an additional lack of about 3,180MW from the grid.

A mixture of the above situations have continued and the overall impact on the grid is persistent low technology, which TCN Operators have needed to attempt to dispatch in a approach that won’t jeopardize the soundness of the grid.

Extra not too long ago, from the first to 4th of March, 2022, there was technology shortfall attributable to water administration in Shiroro and Jebba hydro with the lack of 307MW and 125MW respectively from each stations. Throughout the similar interval, there have been fault and technical issues in Egbin, inflicting 514MW shortfall and in Geregu inflicting 230MW shortfall, whereas reported fault at Alaoji NIPP lowered technology from the substation by 263MW.

Gasoline constraint alone in Olorunsogo fuel producing plant lowered technology from the station by 104MW, in the identical vein, Omotosho fuel misplaced 102MW and Sapele NIPP misplaced 263MW. In Omotosho NIPP, there was technology shortfall of 233MW and in Omoku a shortfall of 112MW. Two items in Okpai have restricted technology attributable to technical issues inflicting a 204MW drop in technology and in Afam VI 511MW drop in technology.
Gasoline constraint and fault in Olorunsogo NIPP lowered technology by 240MW, Geregu NIPP by 435MW, and Ihovbor by 142MW. Additionally, attributable to fuel pipeline pigging, Odukpani NIPP was SHUT DOWN which brought on a discount of technology by 575MW.

TCN additional reiterates {that a} mixture of points starting from fuel constraints, fault, and technical issues inside producing vegetation brought on persistent low technology and consequently low load allocation to Distribution Corporations nationwide. That is based mostly on the truth that TCN can solely transmit what’s being generated by GenCos and presently they’re all producing under capability.

You will need to observe that besides cumulative energy technology will increase significantly for TCN to transmit to distribution corporations nationwide, TCN will probably be left with no selection than to proceed to load shed. We are going to nonetheless proceed to work onerous to make sure the environment friendly allocation of the overall load generated by energy producing stations into the grid, making an allowance for the necessity to make sure that the nationwide grid is steady regardless of the challenges posed by inadequate load on the transmission grid.
