The Transmission Company of Nigeria (TCN) has said its Tower No. 62, along the Okpai-Onitsha 330kV double circuit transmission line in Delta State was vandalised last Tuesday.
The line which evacuates power from the 480 megawatts (mw) Okpai Power Station in the state was hacked down at Asaba Uchi, Ndokwa East Local Government resulting in the loss of 480mw from the national grid, TCN said.
With the shutdown of Okpai plant, peak power generation reported by the Presidential Taskforce on Power was at 4,330mw last Sunday. Daily average generation was at 4,147mw per hour of which 4,071mw per hour was averagely sent out for delivery.
A statement from its management yesterday said the incidence which took place about 4:51am on November 10, 2015 caused a power trip off along the line with the fault traced to the vandalised tower that had its two legs cut off, causing it to hang.
