TCN Makes Clarification On Onitsha Sub-Region Incident, Faults Enugu Distribution Company’s Claim

The Transmission Company of Nigeria  (TCN) has given explanations on the actual cause of the loss of power in the 330kV switch yard at Onitsha Sub-Region, which occurred on August 21, 2025.

It further faulted claims by the Enugu Electricity Distribution Company PLC (EEDC) which had suggested that there was an explosion regarding the cause of the power outage in Anambra State and Oji River in Enugu State.

According to TCN, “Contrary to EEDC’s claim, there was no explosion at the Transmission Company of Nigeria (TCN) station at Onitsha Sub-Region.

The actual cause of the partial loss of power in the 330kV switch yard at Onitsha Sub-Region, which occurred on August 21, 2025, at about 02:34 hours, was an insulation flashover of porcelain insulator (P1) of the red phase jumper conductor to bus bar 1 due to rainfall.

“The power was later restored at 17:54 hours the same day. Notably, TCN had planned a scheduled outage on August 31, 2025, and September 1, 2025, to replace the stack porcelain insulators.

“We clarify that there was no explosion of equipment or loss of switchgear equipment in the TCN Onitsha region.”

A statement by the TCN General Manager, Public Affairs, Ndidi Mbah urged EEDC to ensure the accuracy of information disseminated to the public,  as deliberate deception or propaganda is unprofessional and unacceptable.
