The Nigerian electricity grid lost 2,424 megawatts (mw) to gas, water and transmission line constraints across the Generation Companies (GenCos) last Friday, Daily Trust reports.

Industry statistics revealed that 1,962mw was lost due to gas supply shortage to nine thermal GenCos; line constraint hindered the transmission of 200mw from Afam VI GenCo while the rest of the 260mw was lost due to water constraint at Shiroro hydro GenCo.

The peak generation for the day was 4,196mw and the off-peak period had 3,393mw. But for the triple constraints, the national grid would have had 6,620mw peak generation, being the highest after a peak of 5,076mw was reached in February 2016.

As at the weekend, the power sector had the capacity to deliver 9,084mw of electricity. However an average of 3,176mw was actually generated using 2,906 metric standard cubic feet per day (mmscf/d) of gas. A generation capacity of 5,908mw was stunted because of inadequate gas supply to the GenCos.
