As a result of this, the nation’s total electricity generation dropped to 3,402.5MW on Sunday from 3,940.5MW on Wednesday, according to industry data. The generation from Egbin, the nation’s biggest power station also dropped to 451MW from 465MW on Wednesday.

Olorunsogo II could not generate any megawatt of electricity because its units GT1, 2, 3 and 4 and ST2 were out due to gas constraints, and the ST1 out on maintenance. The plant produced 130.9MW on Wednesday.

Units GT1 and 2 of Trans-Amadi were said to be out on undisclosed reasons, while the GT4 was out due to gas constraints. It generated 15MW of electricity on Wednesday.

Other plants that did not produce electricity on Sunday were Alaoji II with an installed capacity of 250MW; Ihovbor II, 337.5MW; Afam VI, 650MW; Rivers, 160MW; Afam IV & V, AES and ASCO, whose capacities were put at zero.

The nation’s unutilised generation capacity rose to 4120.1MW on Sunday from 3,473.8MW on Wednesday, with gas constraints responsible for about 80 per cent of the stranded capacity at 3,269MW.

Other factors were line constraints and high frequency occasioned by rainfall/loss of distribution companies’ feeder. This led to the shut in of 371.7MW and 479.4MW, respectively on Sunday, up from 368.8MW and 85MW on Wednesday.

The nation achieved its highest power generation of 5,074.70MW on February 2, 2016, according to the Transmission Company of Nigeria.
