FG approves East, West super grids to raise transmission capacity to 19,000MW

The Federal Government approved the start of procurement for the proposed East and West Super Grids. These are major transmission projects, not new power plants. Their purpose is to strengthen the national electricity backbone and move electricity from generation points to consumers more reliably.

The planned network would connect important parts of Nigeria, including corridors running from Sokoto through Abuja and into southern areas. The government also approved a 33kV line linked to Katampe, three large transformers for Ikeja West, and an upgrade of the Itumola–Mapasin–Shagamu line.

The intended change is substantial. Reliable transmission capacity is expected to rise from about 5,000MW to 19,000MW within two years. That would help reduce stranded generation, improve grid resilience, and deliver more electricity to homes, businesses, and industries.

A super grid is a large, high-capacity network of transmission lines that connects major generation areas with distant demand centres. It allows electricity to travel across regions instead of remaining trapped near where it is produced. That matters when one part of the country has available power but another needs more.

Nigeria’s proposed East and West Super Grids would strengthen links across the north and south. The article describes corridors running from Sokoto through Abuja and other locations into southern Nigeria. They would work alongside substations, transformers, and upgraded lines serving Abuja and Lagos.

Existing transmission infrastructure can reliably carry only about 5,000MW, even though more than 13,000MW is available for generation. The super grids would provide stronger, higher-capacity routes. Their goal is to reduce instability and evacuate power that currently remains stranded before reaching consumers.

Nigeria’s capacity gap is larger than 8,000MW when available generation is compared with reliable transmission. The country has more than 13,000MW of available generation capacity, but the existing transmission network can reliably wheel only about 5,000MW.

The government’s proposed solution is to raise transmission capacity to 19,000MW within two years. That target is more than three times the present reliable level. It focuses on the network that carries electricity, rather than simply adding more generating capacity.

This difference explains why additional power does not automatically reach consumers. Generation can remain stranded when lines, substations, or transformers cannot carry it onward. The East and West Super Grids, alongside other approved upgrades, are intended to close that bottleneck and support more dependable electricity delivery.

Generation capacity and transmission capacity are different parts of the electricity system. A power plant may be able to produce electricity, but that power still needs strong lines, substations, and transformers to travel to consumers. Nigeria has more than 13,000MW of available generation capacity, yet its network reliably carries only about 5,000MW.

That bottleneck means electricity can be available at the source but unable to move where it is needed. Ageing or weak assets, limited transmission routes, and grid instability can restrict how much power is safely delivered. The result is stranded generation alongside insufficient supply for consumers.

The government’s audit is examining infrastructure in three major energy zones to find assets needing replacement or rehabilitation. The proposed super grids and related upgrades are meant to expand the network’s carrying ability, improve resilience, and connect supply with homes, businesses, and industries.

If the projects are completed, more electricity should move from generation points to consumers. The government expects stronger transmission to improve grid resilience, reduce instability, and help homes, businesses, and industries receive more dependable power.

The upgrades include a 33kV double-circuit line connected to Katampe, three 300MVA transformers for Ikeja West, and reconstruction of the 35.6-kilometre Itumola–Mapasin–Shagamu line into a double-circuit route. These assets would strengthen supply around Abuja and the Lagos–Shagamu corridor.

The wider benefit would be better use of existing generation. Nigeria has more than 13,000MW available, but only about 5,000MW can be reliably transmitted today. Raising the target to 19,000MW could reduce stranded power and support rising demand, although the article says equipment, debt, and infrastructure weaknesses still need attention.

Transmission investment is prioritised where electricity demand is especially high or where stronger links can support major economic activity. The government identified Lagos–Ogun, Benin–Edo–Port Harcourt, and Abuja–Kaduna–Kano as priority corridors. These routes connect important demand centres and industrial areas.

Lagos–Ogun is particularly significant because it accounts for about half of national energy demand. The government also approved equipment for Ikeja West, a critical transmission node supplying Lagos, and an upgrade along the Lagos–Shagamu corridor. Abuja received a separate Katampe-connected line intervention.

Demand centres influence investment because power must reach the places using the most electricity. Strengthening these routes can ease pressure where shortages affect many homes, businesses, and industries. The nationwide technical audit is intended to identify where replacement or rehabilitation will produce measurable impact instead of funding the wrong projects.

Electricity normally leaves a power plant at a voltage suited to transmission, then travels long distances on high-voltage lines. Substations manage the flow and change voltage levels. Transformers step voltage down for regional networks and, later, for local distribution to homes, businesses, and industries.

The article highlights this chain through specific projects. A 33kV line will connect to the Katampe Transmission Substation. Three 300MVA, 330/132/33kV transformers will be supplied to Ikeja West. The Itumola–Mapasin–Shagamu 132kV line will be rebuilt as a double-circuit route, providing another transmission path.

These components matter because a failure or capacity limit at any stage can restrict delivery. The article says Nigeria can generate over 13,000MW but reliably transmit only about 5,000MW. The planned upgrades aim to carry more power safely and consistently to consumers.
