Critical pieces of transmission equipment which the Transmission Company of Nigeria says are responsible for massive transmission handling are currently out of service across the country due to fault, fire incidents and vandalism, thus worsening the already precarious power supply situation nationwide.

The 162MVA 330/132/33kV transformer at the Ajaokuta Transmission Sta¬tion is out due to unavailable secondary lightning arrester, while the 90MVA 330/132/33kV transformer at the Brinin Kebbi Transmission Station is also said to be out due to yellow and blue phases’ bushing problem. The 45MVA 132/33/11kV and 40MVA 132/33kV transformers at the Akoka Transmission Station are down due to a fire outbreak that affected the blue and yellow-phase CVT and the lightning arrester. The other non-functional transmission lines in the La¬gos region include the 132kV Akangba/Itire line 1, which is affected by a faulty line isola¬tor at the Akangba Transmis¬sion Station; the 132kV Ikeja West-Ilupeju line 2, which is out due to a cut red phase conductor; and the 330kV Egbin/Aja line 4.

A 60MVA 132/33kV transformer at the Onitsha Transmission Station was said to have been isolated due to oil leakage on the same day. Thirty other transmission lines are currently out due to missing sky wires. Records showed that the Omotosho/Ikeja West line, Egbin/Ikeja West line 3; Ikeja West/Olorunsogo line; 330kV Ikeja West/Osogbo line; Ikeja West/Alimosho/Ogba 132kV lines 1 and 2; and the Ikeja West/Akangba 330kV line 2 are all out due to missing sky wire.
