Grid restoration suffered a setback but has been addressed – TCN

The Transmission Company of Nigeria (TCN) has said that its attempts to restore the national grid after initial collapse, suffered a setback but the challenge was promptly addressed.

In a September 14 statement signed by Ndidi Mbah, the company’s General Manager for Public Affairs, the company said some parts of the country have now been reconnected to the power supply.  

The statement read as follows: 

The TCN has previously underscored its commitment to preventing future grid collapses through innovative measures. 

One of these measures is the implementation of the Free Governor Mode of Operation (FGMO), a system that autonomously adjusts power generation to counter frequency changes. 

This dynamic adjustment ensures grid stability, reliability, and a reduction in transmission losses. Moreover, to address the challenges posed by occasional generation shortfalls and the subsequent decline in frequency, TCN has strategically deployed an under-frequency relay scheme. 

This scheme operates at critical stages to proactively prevent disruptions caused by frequency issues. It achieves this by either triggering circuit breaker trips or alerting network operators, effectively averting the risk of system collapse.
