The Transmission Company of Nigeria, TCN, has disclosed that a sudden collapse in power generation across six thermal stations has led to the loss of 1,087.6 megawatts, MW, and is responsible for the epileptic electricity supply which started 24 hours ago in parts of the country.

The TCN stated this in reaction to the development stated that the gas pipeline rupture on June 15, 2018, as well as technical issues at the Shell gas wells on June 16, caused there has been a sharp drop in generation from the grid by averaging a total of 1,087.6MW, resulting in load-shedding nationwide, necessary to maintain stability of the grid.

Due to the Nigerian Gas Company, NGC, pipeline incident, TCN said that the six (6) thermal power generating stations are currently generating zero megawatts of electricity and have therefore been shut down.

The affected power stations included; Ihovbor, Azura, Omotosho gas, Geregu gas, Olorunsogo gas, Sapele and the Egbin Power Station which managed to generate 60MW only on each of its units, losing a total of 211MW.

This was made known by the TCN General Manager, Public Affairs, Mrs. Ndidi Mbah, who said the transmission system has become quite fragile with a total loss of 1,087.6MW into the grid, but assured that TCN was working hard to avert a collapse of the system by engaging in load-shedding.

Load-shedding, she explained in a statement issued on Sunday, is to ensure that available generation is commensurate with what is allocated to discos nationwide, to create a balance and avert grid instability.

Mbah explained further that NGC was making efforts to ensure that the gas pipeline issues are resolved in order to restore normal gas supply to the affected power generating stations, to enable them generate into the grid.

TCN noted that there has been no collapse of the grid as being reported, adding that, the company was appealing for understanding while assuring that its engineers are working hard to continue to maintain the stability of the grid, pending completion of repairs of the gas pipeline by NGC and restoration of full gas supply to the affected generating stations.

The statement read in part: “Due to the NGC pipeline incident, six (6) thermal power generating stations are currently unable to generate electricity and have therefore been shut down.

The affected power stations include the Ihovbor, Azura, Omotosho gas, Geregu gas, Olorunsogo gas, Sapele and the Egbin Power Station which has managed to generate 60MW only on each of its units, losing a total of 211MW.

“Also, Afam VI power station was shut down so that Shell Oil Company can resolve its gas well issues to enable it commence gas supply to Afam VI power station.

“With a total loss of 1,087.6MW into the grid, the transmission system has become quite fragile and that TCN is working hard to avert a collapse of the system by engaging in load-shedding.

“NGC is making efforts to ensure that the gas pipeline issues are resolved in order to restore normal gas supply to the affected power generating stations, to enable them generate into the grid. Meanwhile, Shell has resolved its gas well issue this morning and gas supply partially restored to Afam VI.

“The company appeals for understanding and assures that its engineers are working hard to continue to maintain the stability of the grid, pending completion of repairs of the gas pipeline by NGC and restoration of full gas supply to the affected generating stations.”

Meanwhile, data from the Federal Ministry of Power, Works and Housing on Friday showed that the grid collapsed on June 8, bringing the number of total collapses recorded so far this year to seven.
Following the collapse of the grid, total electricity generation plunged to 2,202.40MW as of 6am on June 9, down from 3,669.20MW on June 8.

Fifteen out of the nation’s 27 power plants were not generating any megawatts as of 6am on June 9, as the collapse led to the shutdown of five additional plants, including Egbin in Lagos.

The other affected plants were Sapele I, Geregu I, Sapele II and Alaoji, joining Afam IV & V, Geregu II, Olorunsogo II, Odukpani II, Gbarain, AES, ASCO, Omoku, Trans-Amadi and Rivers on the list of idle plants.

As of June 12, generation rose to 3,720.60MW as Egbin, Geregu, Alaoji and Omoku came back on stream, while 10 plants remained idle, according to the latest data from the ministry.
Electricity on the grid increased to 3,992.60MW on Friday, June 15, according to generation figures obtained from the Nigeria Electricity System Operator, an arm of the Transmission Company of Nigeria.

The system operator put the nation’s installed generation capacity at 11,165.40MW; available capacity at 7,139.60MW; current transmission capacity at 7,000MW; network operational capacity at 5,500MW and the peak generation ever attained at 5,222.3MW.
