Nigeria Grid & Transmission

Focus: Environmental & Safety Perspective | Kuje/Wumba/Lokogoma, FCT Abuja | 5km 132kV Underground XLPE | Oil Containment + Fire Safety | TCN June 2022 High-voltage substations are rarely thought of as environmental projects. But the design choices made at Kuje and Wumba/Lokogoma show how grid infrastructure can reduce its footprint and support a cleaner energy future. Substations are the unglamorous workhorses of the power system. They do not generate electricity, yet way they are designed and built has real environmental and safety consequences. The Kuje/Wumba/Lokogoma Substations Project, delivered by ICC for Transmission Company of Nigeria and certified complete in June 2022, offers useful case study. Going underground — 5km XLPE avoids towers and cleared corridors. (1k/low) Going Underground: 5km of 132kV XLPE Cable One of project's most significant environmental features is approximately 5 km of 132kV underground XLPE cable connecting New Apo Substation to new Wu...

Focus: Environmental Perspective | 30MWp Kabba 2x60MVA Substation, Kogi | ~40 GWh/year Clean Energy | Grid-Integrated Solar A 30MWp solar plant feeding a major substation in Kogi State shows how renewable energy can be woven into Nigeria's existing grid, not just built beside it. Much of the conversation about renewable energy in Nigeria has focused on off-grid systems: solar home kits, mini-grids and standalone installations. The contract awarded in March 2020 for the 30MWp Solarization of the 2x60MVA Transmission Substation at Kabba, Kogi State , takes a different approach. It brings utility-scale solar generation directly into the national grid infrastructure. The contract, awarded by the Rural Electrification Agency to International Consolidated Contractors Offshore SAL under the Nigeria Electrification Project, reflects that the grid itself must become cleaner. Clean power at grid edge — 30MWp woven into existing grid. (1k/low) How Much Clean Energy? ~40 GWh/Year Kogi...
