The Transmission Company of Nigeria stated that the Nigerian power grid has been stable for 400 days without interruptions or system failures, totaling 13.3 months.
TCN’s general manager, Mrs Ndidi Mbah, hailed the milestone achievement in a statement on Tuesday.
According to the firm, the milestone represents a significant advancement in the country’s efforts to strengthen its power infrastructure and ensure a stable electricity supply to distribution load centers for onward distribution to electricity users nationwide.
It stated that the ongoing stability and reliability of the Nigerian power grid may be due to a mix of strategic measures and TCN management investments in the power system.
The GM noted some of the main factors that led to the extraordinary achievement, such as Configuration and Enforcement of Free Governor Control, as well as an excellent Under-frequency Relay Scheme.
“TCN formed a three-person committee to go around the country for the configuration and activation of Primary Reserve in coordination with power stations and in accordance with the provisions in the Grid code,” she said.
“After activating the unit governor control, this committee devised a robust monitoring and enforcement mechanism for generating station compliance.”
The Free Governor Mode of Operation is a unique approach that automatically adjusts generation in response to frequency changes, assuring stability, reliability, and decreased transmission losses.
“Under Frequency Relay Scheme, TCN implemented a strategic deployment of under frequency relay scheme to counter the challenges posed by occasional generation shortfalls and resulting frequency declines.
This technique works in stages to prevent frequency-related interruptions by tripping circuit breakers or alerting network operators, preventing system collapse.”
“TCN in-house engineers deployed the IoT/VPN for Enhanced Grid Visibility by creating an interim solution using loT sensors and devices,” she said.
She also added that efforts are currently underway to increase this visibility by adding additional transmission stations via loT integration.
To safeguard the integrity of power plants, transmission lines, and substations, she stated that the firm focused on implementing an expanded maintenance regime that included frequent inspections, timely repairs, and proactive preventive maintenance measures.
She also stated that the dedicated teams of trained staff have consistently demonstrated proactive response during emergencies, contributing to rapid crisis resolution and minimal disruptions and that their collaboration, clear communication, and continuous training demonstrate their commitment to grid management and resilience.
According to her, TCN’s engagement with stakeholders in the Nigerian Electricity Supply Industry has resulted in joint efforts such as Power Purchase Agreements, Service Level Agreements, Power Evacuation Agreements, and NESI situation room reports. Regular assessments improve real-time monitoring and adjustment, resulting in a more resilient power landscape.
“The achievement of over 400 days of uninterrupted stability by the Nigerian power grid demonstrates the country’s commitment to advancing its power infrastructure.”
“This success has been achieved through increased efficiency, technology, dedicated personnel, strategic measures, and collaborative partnerships.” This accomplishment exemplifies the energy sector’s potential for good reform. The country is ready for a stronger and more reliable power system with steadfast determination, continued investments, and collaborative efforts,” she added.
