National Grid Trips Multiple Times, Now Stabilised, Says NISO
The national grid tripped multiple times on the 330kV transmission network on Monday but has been stabilised and returned to normal operation, the Nigerian Independent System Operator (NISO) has said. NISO’s management…
Nigeria's national grid, operated by the Nigerian Independent System Operator (NISO) — the successor to the Transmission Company of Nigeria's system operations arm following the power sector's recent restructuring — has a long history of collapses and trippings that leave swathes of the country in darkness. These disruptions are often blamed on an ageing and fragile 330kV transmission network, inadequate generation to match demand, and poor coordination between generation, transmission and distribution companies, which operate as separate entities since the sector's privatisation.
Grid instability remains one of the most persistent complaints against Nigeria's electricity industry, with businesses and households routinely bearing the cost of outages through reliance on generators and other backup power sources. Both Leadership and Vanguard report that NISO confirmed Monday's multiple trippings and says it has since applied corrective measures to restore stability, though neither account yet details the specific cause of the trippings, the extent of the blackout they caused, or how long restoration took.
