Nigeria has again witnessed a nation-wide blackout as a result of another system collapse, which occurred around 12:21 pm on Wednesday.
However, details of the collapse are sketchy as at press time.
The new development has put the total number of grid collapses recorded to four in the first half of 2021, starting with the February 17 collapse, then followed by March 15, May 12 and July 28 (yesterday) 2021 respectively.
The national grid is controlled and operated by government-owned Transmission Company of Nigeria.
Power system collapse is the process by which the sequence of events accompanying voltage instability leads to an unacceptable voltage drop in a significant part of power system.
Meanwhile, Ikeja Electric Plc on Wednesday in a notice to its customers said, “The current power outage is due to a nationwide system collapse that occurred at about 12:26hrs.
Power supply will be restored gradually to various parts of the network as soon as the Grid is stabilized.”
Abuja Electricity Distribution Company also in a notice to its customers said, “We have been unable to serve our customers in Niger, Kogi and Nasarawa states as well as a significant portion of the entire Federal Capital Territory.”
While Enugu Electricity Distribution Company(EEDC) in its ownstatement released by Emeka Ezeh, Head, Corporate Communications,said, “we lost supply this morning from our sources of power supply at Awada – New Haven and Egbu Transmission Stations, due to a total system collapse.
“This has informed the present power outages being experienced by our customers across our network. Work is on-going by the TCN engineers to identify the fault, clear it and restore supply accordingly and we are on standby to restore our feeders once this is concluded.
Earlier, the Association of Nigerian Electricity Distributors (ANED), the umbrella body of distribution companies, attributed the situation to obsolete, analogue systems being used by the TCN.
