The national electricity grid lost 2,591 megawatts (mw) on Wednesday due to gas shortage, line constraint and low water level across 12 Generation Companies (GenCos), Daily Trust reports.
Daily power generation statistics showed that the peak (highest) generation was 3,932mw on April 5, 2017 from which 87,244 megawatts hour (mwh) energy was sent out through the Transmission Company of Nigeria (TCN) to the 11 Distribution Companies (DisCos) for supply to end users.The industry data also showed that 77 turbines were available and could have produced 6,887mw if the dominant tripartite constraints of gas, line and water level were addressed. However, only 44 worked, producing 3,486mw off peak, while 33 turbines were shutdown.
A breakdown indicates that gas constraints accounted for 2,443mw of the power loss in 10 gas-based power stations. Water management also affected power generation in the mid-week. Jebba Hydro lost 90mw as one turbine was unutilised due to low water levels. For transmission line constraints, Ibom Power was affected as one of its turbines did not produce, hence, losing 57.6mw.
