National Grid Fully Restored After Disturbance – TCN

 

The Transmission Company of Nigeria (TCN) announced the full restoration of the national power grid following a partial collapse on Saturday. Ndidi Mbah, TCN Public Affairs General Manager, explained that the grid disturbance occurred at approximately 15:09 hrs on July 6, 2024. This marks the third partial grid disturbance and the first total disturbance this year.

Cause of the Collapse

Mbah stated that the collapse was likely triggered by the unexpected tripping of three units at a power-generating station, which suddenly removed 313MW from the grid, causing system instability. The system operator responded by isolating a section of the grid, including the Ibom Power Station, to maintain power supply to specific areas while restoring the affected part of the grid by 21:57 hrs the same day.

Consumer Reactions and Concerns

Electricity consumers have expressed frustration over the recurring grid collapses, particularly following a recent tariff increase approved by the Nigerian Electricity Regulatory Commission. Princewill Okorie, Executive Director of the Electricity Consumer Protection Advocacy Centre, criticized the inefficiency in the power sector despite higher tariffs, calling for better management and transparency in the use of funds.

Calls for Accountability and Restructuring

Adetayo Adegbemle, Executive Director of PowerUp Nigeria, emphasized the need for accountability within the electricity value chain. He suggested that leadership changes might drive more effective collaboration and prevent future grid collapses. Adegbemle highlighted the importance of aligning the value chain, referencing the Siemens deal aimed at improving the sector.

Regional Impact

The Enugu Electricity Distribution Company confirmed that its TCN stations were out of supply, affecting customers in Abia, Anambra, Ebonyi, Enugu, and Imo states.
