TCN LAGOS REGION TAKES DELIVERY OF A BRAND NEW 300MVA POWER TRANSFORMER . . . Boosts Transmission Capacity

The Transmission Company of Nigeria (TCN) took delivery of a brand new 300MVA 330/132/33kV power transformer at its Lekki 330/132/33kV Transmission Substation on

April 30, 2023, the latest addition of new transformers delivered to the substation. Earlier, the substation received two brand new 60/75MVA power transformers in February and three heavy-duty truckloads of transformer components in January, 2023, among others.

TCN Management through its Lagos Region has continued to ensure prompt execution of transmission projects within the Region. This entails the upgrade or total overhaul of its equipment where needed to achieve a more effective and efficient bulk transmission of electricity to the

distribution load centers of the Ikeja and Eko DisCos and reduce to minimal, downtime that would have resulted from equipment failure. The Region equally undertakes the prompt maintenance of equipment to further preserve its lifespan.
On installation, the 300MVA 330/132/33kV

power transformer will add 240MW to the Lekki Substation capacity. Presently, arrangements are being made to put the transformer on the plinth to enable its installation.
Meanwhile, under Lagos Region, several substations and line projects have been completed in the last one

year, some of these include:
- Reconductoring and commissioning of the New Ikorodu/Shagamu 132kV line
- Installation of 1x60MVA transformer at Egbin 132kV Substation
- Installation of new 60MVA 132/33kV transformer at Itire 132kV Substation
- Diversion of Aja/Egbin 330kV

lines 3 & 4 to Aja/Omotosho/Epe 330kV lines 1&2
- Replacement of 3nos defective circuit breaker interrupter of T1 45MVA transformer secondary circuit breaker.

The Region has equally changed several other circuit breakers in different areas of the transmission region.

The Lagos Region is also undertaking several transmission projects, which are at various stages of completion. Some of them are as follows:
- Construction of 2x60MVA 132/33kV Eko Atlantic Transmission Substation
