TCN’s general manager, Mrs Ndidi Mbah, announced the milestone achievement in a statement last week.

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

It said the sustained stability and reliability of the Nigerian power grid could be attributed to a combination of strategic measures and investments in the power system by the Management of the TCN.

The GM listed some of the key elements that have contributed to the remarkable accomplishment, including Configuration and Enforcement of Free Governor Control, effective Under-frequency Relay Scheme, among others.

She said that, “TCN constituted a three-person committee that was formed 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.
