The Nigerian Electricity Supply Industry (NESI) on Tuesday
recorded 0Mega Watts spinning reserve, which made the grid unstable.
According to a source from the industry, “there was zero MW spinning reserve on Tuesday, and it made the grid extremely unstable. It was a difficult decision to take but there was no point building up a back-up when there was no energy to send out.”
In its data on daily summary system performance, NESI however said that on Monday, the electricity market lowest generation was 2,482.90MW while it sent out an average of 2,530MW.
The market lost 3,667MW to gas constraint, 136MW to management constraint and 380MW to water management constraint, which culminated in a financial loss of N2,008, 000, 000.
The daily summary said : “On May 30 2016, average energy sent out was 2530MWh/hour (up by 552Mwh/h), The reported gas constraint was 3,667MW. The reported line constraint was 136MW. The water management constraint was 380MW.
The power sector lost the estimated equivalent of N2,008, 000, 000 on May 30 2016 due to constraints.”
Prior to the attacks on the pipelines spinning reserves was about 72MW but it was 9MW on May 27, rose to 32MW on May 28, and dipped to 9MW on May 29 and on Monday it reduced to 9.8MW. But yesterday it was 0MW, according to our reliable. The Transmission Company of Nigeria (TCN) is presently capable of transmitting between 5,500MW and 6,000MW.
