The Nigerian Electricity Supply Industry (NESI) yesterday announced that following gas, line and frequency constraints, the power sector reduced power supply by 3,844 Mega Watts (MW) on Tuesday.
On the day under review, according to its website report, the Nigerian Electricity System Operator (SO) of the Transmission Company of Nigeria (TCN) sent out 3,169MW to the 11 distribution companies in the sector.
Following the constraints encountered in the generation, distribution and transmission chains, the sector recorded an estimated loss of N1,845, 000, 000 on the day under review.
NESI said : “On September 06 2016, average power sent out was 3169MWh/hour (down by 115MWh/h). The reported gas constraint was 3004MW. The reported line constraint was 415MW according to TCN. The reported high frequency constraint is 425 MW. The water management constraint was 0MW. The power sector lost the estimated equivalent of N1,845, 000, 000 on September 06 2016 due to constraints.”
It had on Monday recorded loss of 3,610MW as gas constraint was 2,932MW, line constraint was 388.4MW, while frequency constrain was 290MW.
Following the challenges in the sector production chains, the Nigerian Electricity System Operator (SO) of the Transmission Company of Nigeria (TCN) could only evacuate 3284MW to the 11 distribution companies (DisCos).
On the day under review, said NESI, there was no record of water management constraint.
It however noted that the various losses or constraints culminated in an estimated loss N1,733, 000, 000.
The NESI said: “On September 5, average power sent out was 3284MWh/hour (down by 34MWh/h). The reported gas constraint was 2932MW.
“The reported line constraint was 388.4MW, according to TCN. The reported high frequency constraint is 290 MW. The water management constraint was 0MW.
“The power sector lost the estimated equivalent of N1,733, 000, 000 on September 5 due to constraints.”
In its September 6 report, the SO said that at 6.00hour of September 7, the NESI generated 3,215.70MW. It added that the total energy sent out on the previous day was 3,169MW, hit a peak generation of 3,710.4MW and 2,834.40MW lowest generation.
According to the report, the sector recorded 51.55Hz highest frequency and 48.78Hz lowest frequency.
From the reports, power generation that was 3,521.90 Mega Watts (MW) on Sunday, Tuesday dipped to 3,228MW, and on Wednesday further dipped to 3,215.70MW.
This resulted in 293MW drop in power on Tuesday and a further dip by 13MW on Wednesday.
resulting in 293MW drop in power produced by the generation companies( GENCO.)
