Nigeria Grid & Transmission

Focus: Economic Perspective | Kuje/Wumba/Lokogoma Substations, FCT Abuja | $48,624,245 | 5x60MVA = 300MVA | TCN + ICC | Certified 24 June 2022 Electricity cannot power an economy if it cannot reach it. A $48.6 million transmission project in the Federal Capital Territory tackles one of the most overlooked bottlenecks in Nigeria's power sector. When Nigerians talk about electricity, the conversation usually turns to generation: how many megawatts power stations can produce. But generation is only part of story. Power must be transmitted, transformed and distributed before it reaches a home, office or factory. When any link is too weak, electricity that could have been used is lost to economy. The Kuje / Wumba / Lokogoma Substations Project , delivered for the Transmission Company of Nigeria by International Consolidated Contractors, was designed to strengthen that chain in one of country's fastest-growing regions. Awarded in May 2020 at $48,624,245 , certified complete on ...

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: Technical Perspective | Kuje/Wumba/Lokogoma 132/33kV Substations, FCT | 5x60MVA =300MVA | 11x 132kV AIS Bays | 5km XLPE Underground | Certified 24 June 2022 From 60MVA transformers to 5 km of underground high-voltage cable, the Kuje / Wumba / Lokogoma project was a complete engineering, procurement and construction undertaking. Here is what it involved. A transmission substation is where the grid changes gear. Power arriving at high voltage is stepped down, switched, protected and sent out to distribution networks. Designing and building one from scratch involves civil engineering, heavy electrical equipment, sophisticated protection systems and digital control, all integrated into a single functioning system. The Kuje / Wumba / Lokogoma Substations Project, awarded by Transmission Company of Nigeria to International Consolidated Contractors in May 2020, delivered two such substations and an underground cable connection. TCN's certificate confirms full scope was comple...

Focus: Social Perspective | Kuje/Wumba/Lokogoma Substations, FCT Abuja | TCN Certified Complete June 2022 | 5km Underground Cable | 24-Month On-Time For the residents of Kuje, Lokogoma and Wumba, two new substations are about more than infrastructure. They are about the everyday experience of living in a fast-growing city. Abuja's growth has been one of Nigeria's great urban stories. Over the past two decades, population expanded rapidly, new neighbourhoods spread across what was once open land. For families who moved into these communities, promise of modern city life has sometimes been undercut by infrastructure that arrived later than residents. Electricity has been one of the most visible gaps. Overloaded substations and weak supply mean frequent outages, low voltage and heavy generator dependence. The Kuje/Wumba/Lokogoma Substations Project, certified complete and fully operational by Transmission Company of Nigeria in June 2022 , was built to change that experience....

Focus: Governance & Procurement | Kabba 30MWp, Kogi State | REA-NEP/C/GO/RFP/47/25E | $41,144,857.96 | Proposal 8 Jan 2020 → Award 3 Mar 2020 A two-page notification of award for a $41 million solar contract offers a revealing look at how accountability is being built into Nigeria's energy investments. Public infrastructure in Nigeria has too often been associated with inflated contracts, opaque ownership and projects that never reach completion. Against that background, the procurement process behind the 30MWp Solarization of the 2x60MVA Transmission Substation at Kabba, Kogi State , is worth examining. On 3 March 2020 , the Rural Electrification Agency, acting through its Nigeria Electrification Project, notified International Consolidated Contractors Offshore SAL (Beirut) that its proposal had been accepted. The contract, numbered REA-NEP/C/GO/RFP/47/25E , carries $41,144,857.96 inclusive of all indirect taxes . A Structured, Competitive Process The award reflects a ...

Focus: Technical Perspective | 30MWp into 2x60MVA Transmission Substation | Grid Engineering | Kabba, Kogi State Integrating 30MWp of photovoltaic generation into a 2x60MVA transmission substation is a demanding exercise in grid engineering. Here is why it matters and what it involves. Most solar projects in rural Nigeria have been mini-grids: self-contained systems serving a defined community. The 30MWp Solarization of the 2x60MVA Transmission Substation at Kabba, Kogi State , awarded by REA to ICC Offshore SAL in March 2020, belongs to a different category. It connects utility-scale solar to high-voltage grid infrastructure. 120MVA substation — 2x60MVA transformers. (1k/low) Understanding the Substation: 120MVA Capacity A transmission substation is a node where power arriving over high-voltage lines is transformed down to lower voltages for distribution. Kabba's two 60MVA transformers give combined capacity of 120MVA . A 30MWp solar plant therefore represents substantial ...
