When discussions about Nigeria’s electricity sector arise, attention is often focused on generation. How many megawatts are available? How many new power plants are being built? How much additional capacity can be connected to the grid?
Yet history has repeatedly shown that generation is rarely the primary reason power projects fail.
Across Nigeria, billions of naira have been invested in generation assets capable of producing electricity. However, much of that power never reaches customers efficiently because the weakest part of the value chain remains distribution. For emerging state electricity markets, this lesson may be one of the most important of all.
Power projects do not fail because electricity cannot be generated. They often fail because electricity cannot be delivered due to inadequate and inefficient networks.
The last mile problem
Electricity only creates value when it reaches a paying customer. A power plant may be operating perfectly. Transmission infrastructure may be available. Financing may have been secured. Yet if the distribution network cannot deliver electricity reliably to homes, businesses, industries, and institutions, the entire value chain begins to break down.
The distribution network is the final link between infrastructure investment and economic impact. When that link is weak, everything upstream suffers. Generation becomes stranded. Transmission assets become underutilised. Investors lose confidence. Consumers resort to self-generation. Economic growth slows. The result is a system where capacity exists on paper but reliability remains elusive in practice.
Why distribution networks fail
Many distribution systems across Nigeria were designed for a different era. Urban populations have expanded dramatically. Industrial activity has increased. Commercial centres have grown. Yet in many areas, network infrastructure has not kept pace.
Common challenges with grid electricity distribution networks include:
- Aging transformers operating beyond design capacity.
- Overloaded feeders serving expanding communities.
- Inadequate substations.
- Poor network maintenance.
- High technical losses.
- Limited network automation.
- Weak fault detection and response systems.
These challenges create a situation where even available electricity cannot be distributed effectively. The consequence is frequent outages, voltage instability, equipment failures, and customer dissatisfaction.
The hidden cost of technical and commercial losses
One of the most damaging consequences of weak distribution networks is the accumulation of losses.
Technical losses occur when electricity is lost through inefficient infrastructure. Commercial losses occur when electricity delivered is not properly billed or collected. Together, these losses can consume a substantial portion of sector revenues.
Every unit of electricity lost creates a chain reaction:
- Distribution companies collect less revenue.
- Maintenance budgets shrink.
- Infrastructure upgrades are delayed.
- Service quality deteriorates.
- Customer willingness to pay declines.
The cycle then repeats itself. What begins as a network problem eventually becomes a financial problem. And financial problems are often what ultimately destroy otherwise viable power projects.
Why investors pay attention to distribution
Investors do not finance megawatts. They finance cash flows. A power project can only generate sustainable returns when electricity reaches customers and revenues are collected efficiently. For this reason, sophisticated investors often spend as much time evaluating distribution infrastructure as they do evaluating generation assets.
A state may possess abundant fuel resources. It may have strong demand growth. It may even have supportive regulation. But if the distribution network cannot reliably deliver electricity and collect revenues, investment risks increase significantly. Strong distribution networks create confidence. Weak networks create uncertainty. Capital naturally follows confidence.
The self-generation economy
Perhaps the clearest evidence of distribution failure is the widespread reliance on self-generation. Across Nigeria, households, businesses, hospitals, schools, and manufacturers spend enormous sums operating diesel and petrol generators.
This parallel electricity economy exists because customers value reliability more than almost any other characteristic of power supply. In many cases, consumers willingly pay significantly higher costs for self-generated electricity simply because it is dependable.
This reveals an important truth: The demand for electricity is not the problem. The challenge is delivering reliable service through sustainable networks.
Lessons for state governments
As states begin building independent electricity markets, distribution must be treated as a strategic priority rather than an afterthought.
The temptation to focus on generation projects is understandable. Power plants are highly visible investments that attract attention and political recognition. However, history demonstrates that generation without distribution creates stranded assets.
States should therefore prioritise:
- Comprehensive network assessments before committing to large generation projects.
- Modernisation of feeders, substations, and transformers.
- Investment in smart metering and revenue assurance systems.
- Network automation and monitoring technologies.
- Electricity planning based on identified demand clusters.
- Infrastructure upgrades that support industrial and commercial growth zones.
Most importantly, states should view generation, transmission, and distribution as a single integrated system rather than separate investments. Electricity markets succeed when every link in the chain functions effectively.
Looking ahead
The future winners in Nigeria’s evolving electricity sector may not be the states that build the largest power plants. They may be the states that build the most reliable distribution networks.
This is precisely because customers do not purchase generation capacity. They purchase delivered electricity.
And in every successful electricity market, one principle remains constant:
Power projects succeed when electricity reaches customers reliably, affordably, and consistently. Everything else is secondary.
