The Delta generation complex, it noted, successfully ran on island mode at the 132kV sub-transmission level, supplying electricity to Oghara, Amukpe, Benin and Efunrun substations. A total of 114 megawatts was generated from four units at the Delta Thermal Power Station during the period.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">NISO said it activated emergency response measures through its National Control Centre in Osogbo, using dispatch and monitoring tools in line with established operational procedures. The operator added that electricity supply has since been fully restored nationwide and system stability normalised.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">While the DisCos focused on immediate service restoration, NISO said investigations into \u201cthe cause and sequence of events leading to the system disturbance are currently ongoing,\u201d assuring that measures would be put in place to prevent a recurrence.<\/div>\n<div style=\"text-align: justify;\"><\/div>\n<div style=\"text-align: justify;\">The system operator reaffirmed its commitment to proactive grid management and best operational practices, even as the differing accounts from NISO and the distribution companies highlighted ongoing communication gaps during major grid incidents.<\/div>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content --><!-- AddThis Related Posts generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>By Daniel Adaji Nigeria\u2019s power sector operators on Monday offered different explanations for the nationwide electricity outage that followed a grid disturbance in the early afternoon.
