Power Grid Has Operated Without System Collapse For Over A Year -TCN

The Transmission Company of Nigeria (TCN) has disclosed that the power grid has maintained uninterrupted stability for over 400 consecutive days.

TCN spokesperson, Ndidi Mbah in a statement on Wednesday, said the power grid operated without any major disruptions or systems collapse within the period.

She said the milestone signifies a remarkable advancement in the nation’s efforts at strengthening its power infrastructure and ensuring a reliable and dependable electricity supply to distribution load centres for onward distribution to customers nationwide.

“The sustained stability and reliability of the Nigerian power grid can be attributed to a combination of strategic measures and investments in the power system by the Management of the Transmission Company of Nigeria (TCN),” she said.

Mbah said some of the key elements that have contributed to the feat include the “configuration and enforcement of free governor control, effective under-frequency relay scheme, among others”.

She said TCN constituted a three-person to go round the country for the “configuration and activation of primary reserve in coordination with power stations and in line with the provisions in the Grid code”.

“This committee devised a robust monitoring and enforcement mechanism for generating station compliance after activating the unit governor control,” the spokesperson said.

“This innovative approach, known as free governor mode of operation (FGMO), automatically adjusts generation in response to frequency changes, ensuring stability, reliability, and reduced transmission losses.

“Under frequency relay scheme, counters the challenges posed by occasional generation shortfalls and resulting frequency declines, TCN implemented a strategic deployment of under frequency relay scheme.”
