According to Punch, Nigeria’s electricity system recovered after a partial national grid collapse triggered by a mid‑afternoon system disturbance that disrupted supply across multiple areas.
The report said the disturbance occurred around 2:01pm on Monday, December 29, with generation slipping after earlier peaking near the day’s highs. NISO attributed the disruption to tripping events affecting multiple generating units and key 330kV transmission lines.
Punch added that gas constraints—linked to the earlier Escravos–Lagos gas pipeline vandalism—left the grid more fragile, worsening the impact once the disturbance hit. NISO also pointed to “island mode” interventions that helped keep supply flowing to some substations during the incident.
Premium Times separately reported that distribution companies issued customer updates during the outage and said restoration would follow once the grid was stabilised, noting work to bring supply back “as soon as the grid is stabilised.” TVC News also reported that the national grid was back online, citing NISO’s account that the disturbance had been addressed.
Echotitbits take: Nigeria’s grid is behaving like a stressed network—any gas disruption or transmission trip can cascade into wide outages. Watch for (1) clearer post‑incident diagnostics from the system operator, and (2) stronger pipeline security and gas supply stability going into 2026.
