TCN Adds 672MW Transmission Capacity to Lagos Power Network
By Peace Erewunmi
The Transmission Company of Nigeria (TCN) has increased the transmission capacity of the Lagos electricity network by 672 megawatts (MW) following upgrades at major transmission substations across the state.
The projects, commissioned as part of efforts to strengthen Lagos’ power infrastructure, are expected to improve the supply of bulk electricity to the Eko Electricity Distribution Company (EKEDC) and Ikeja Electric Distribution Company (IKEDC).
At the Lekki Transmission Substation, TCN commissioned a 300MVA, 330/132/33kV transformer and two 60MVA, 132/33kV transformers.
The intervention doubled the substation’s 330/132kV transformation capacity from 300MVA to 600MVA, equivalent to about 480MW. Its 132/33kV capacity also increased from 120MVA to 240MVA, equivalent to approximately 192MW.
Nine new 33kV feeders were also installed to facilitate the evacuation of bulk electricity into the EKEDC distribution network.
At the Alausa transmission substation, a new 100MVA, 132/33kV transformer increased transformation capacity from 135MVA to 205MVA, equivalent to about 164MW.
TCN said the Alausa upgrade would provide an additional 80MW of bulk power to IKEDC and improve electricity supply to at least 70,000 residents in Alausa and surrounding communities.
The project, executed by Shanghai Electric under a World Bank-funded initiative, involved replacing an existing 30MVA transformer with the new 100MVA unit.
At the Ijora transmission substation, two ageing 30MVA transformers were replaced with two modern 100MVA transformers. The upgrade increased the station’s installed transformation capacity from 90MVA to 230MVA, adding 140MVA to the network.
TCN Managing Director and Chief Executive Officer, Sule Ahmed Abdulaziz, said the projects would help reduce network constraints, accommodate growing electricity demand and improve supply reliability across key commercial and industrial areas of Lagos.
The TCN chief executive said the company would continue investing in transmission lines, substations, transformers and modern grid technologies to ensure that transmission capacity remains ahead of electricity generation.
The latest upgrades are expected to strengthen electricity delivery to homes, businesses and industries across Lagos, although the actual improvement in supply to consumers will also depend on available generation and the capacity of the distribution networks.
