Transmission Company of Nigeria (TCN) regrets to report another System Collapse at 14.19 Hours. Preliminary information from NCC indicated that the tripping of Odukpani-Ikot Ekpene 330kV line, cut off generation from Odukpani Power Station to the grid. Restoration of the grid has reached advanced stage. TCN has also commenced investigations to determine the exact cause of the system disturbance and the outcome will be made public.

The system disturbance happened at a time when work on the Western Gas Pipeline by NGC which caused system collapse at about 21.17Hours yesterday, is yet to be completed. The Grid would have withstood the Odukpani infraction, if generation along Lagos Region were available.

According to General Manager Public Affairs Mrs. Ndidi Mbah, it may not be advisable to put higher loads on the Lagos-Benin and Lagos-Osogbo 330kV lines because of its impact on grid stability. A 330kV line carrying high load could trip and cause system collapse. TCN therefore may not carry enough load to Lagos.

NGC indicated that a contractor has been mobilised to reconstruct the affected segment of the Western Gas Pipeline, so that gas supply to Omotosho, Egbin, and Olorunsogo I and II can be restored. According to NGC the work would be carried out day and night and is expected to be completed within 24 hours.

TCN noted that with the support of the Federal Ministries of Power and Finance, it has embarked on the implementation of Transmission Rehabilitation and Expansion Program that seeks to expand, rehabilitate and stabilize the Grid. TCN appealed for patience and understanding.
