The Transmission Company of Nigeria (TCN) has said it restored the partially collapsed grid and sent out 64,467.24MWH an average of 2,686.135W to the 11 electricity Distribution Companies (DisCos) on Sunday, February 4.
Besides, the TCN also noted that the total energy generated on the day under review was 65,604.49MWH, an average of 2,733.52MW.
Meanwhile, a document The Nation obtained from the TCN indicated that it sent out 2,651MW to the 11 DisCos at 4:38 pm.
Owing to the low energy generation on Sunday, about four DisCos got zero energy allocation from the TCN.
The company’s Public Affairs, General Manager, Ndidi Mbah issues a press statement at 9:26 pm on Sunday describing the situation as a “partial system disturbance.”
The statement blamed the matter on lingering gas supply constraints.
Her statement noted that the grid had been fully restored.
The statement reads in part: “The Transmission Company of Nigeria, TCN hereby states that the grid experienced a partial disturbance at about 11:21Hours today with Ibom power islanded, feeding Eket, Ekim, Itu & Uyo transmission substations, during the period of partial disturbance. TCN initiated immediate restoration of the affected part of the grid, and presently, the grid is fully restored.
“Prior to the incident, total generation on the grid was 3,901.25 MW at 08:00 hours, a little over three hours before the time of the partial collapse. It is important to note that low power generation has persisted since January 2024, to date, exacerbating daily due to the lingering gas constraint.
“According to the National Control Center (NCC), the Internet of Things (IoT) revealed that just before the partial disturbance, which occurred at 11:21Hrs today, Sapele Steam & Egbin Substations lost a total of 29.32MW & 343.84MW at 11:20:14Hrs & 11:20:17Hrs respectively, totalling 373.16MW.
“This, combined with the current low power generation due to gas constraints, caused the imbalance leading to the partial system disturbance.
“Gas constraints continue to impact grid flexibility and stability. Ensuring sufficient gas supply to power generating stations is crucial for grid stability as sufficient generation allows for better grid management in the event of sudden generation losses like this. TCN will investigate the cause of tripping of Sapele Steam & Egbin power generating units.”
