The blackout in some parts of the country resulted from the shutting down of six thermal power generating stations in the country by the Transmission Company of Nigeria, TCN.
The decision is to enable the Nigeria Gas Compnay, NGC, to carry out repair work on a ruptured gas pipeline.
The damaged pipeline, the TCN said was responsible for the reduction in electricity supply across the country.
The rupture of the gas pipeline and other technical issues at Shell gas wells occurred on June 15 and June 16 respectively.
The affected stations are Ihovbor, Azura, Omotosho gas, Geregu gas, Olorunsogo gas, Sapele and the Egbin power stations.
According to a statement issued by the General Manager, Public Affairs, TCN, Mrs Ndidi Mbah, in Abuja on Sunday, the drop in electricity affected a total of 1,087.6Mega Watts of Power nationwide.

Her words: “With a total loss of 1,087.6MW into the grid, the transmission system has become quite fragile and TCN is working hard to avert a collapse of the system, by engaging in load-shedding.
“Load-shedding, is to ensure that available generation is commensurate with what is allocated to DisCos nationwide, to create a balance and avert grid instability.”
She said the problem which led to the adoption of load-shedding strategy also affected the Federal Capital Territory as well as other states of the country.
Mbah, however, said NGC was working hard to restore normal gas supply to the affected stations in order to ensure power supply.
She said Shell had already resolved its gas well issues and gas supply partially restored to Afam VI power station.
Mbah called for the understanding of Nigerians, promising that the problem would soon be over.
