₦120 Billion in Electricity Losses Under Investigation: Can Better Accountability Improve Nigeria’s Power Sector?

The Federal Government is investigating an estimated ₦120 billion worth of unaccounted-for electricity along the Ikorodu–Sagamu industrial corridor. The outcome could have implications for manufacturers, electricity market revenues and efforts to improve accountability across Nigeria’s power sector.

The Federal Government has ordered a technical and forensic investigation into discrepancies in electricity flows and consumption along the 132kV Ikorodu–Sagamu transmission corridor, where up to 100 megawatts (MW) of electricity reportedly went unaccounted for over a 12-month period.

The Nigerian Independent System Operator (NISO), which monitors electricity flows across the national grid, identified unusual loading and consumption patterns using technology-based monitoring systems. The value of the unaccounted-for energy was estimated at ₦120 billion over the period under review.

Following the findings, the Minister of Power, Joseph Tegbe, directed electricity market participants and relevant stakeholders to cooperate with an investigation designed to establish the source of the discrepancies.

The review is expected to examine whether the gaps resulted from technical losses, operational problems, metering errors, inaccurate energy records or possible electricity theft. These are different issues, and determining the actual cause is essential before responsibility can be assigned.

The government has warned against meter tampering, manipulation of electricity data and interference with energy measurement. However, the investigation is intended to establish the facts through technical evidence and due process rather than presume that any particular company or customer is responsible.

The case raises a broader question for Nigeria’s electricity sector: how can the country improve the measurement, billing and accountability of the power it supplies, particularly to major industrial customers?

What Does ₦120 Billion in Unaccounted Electricity Mean?

To understand the significance of the investigation, it is important to distinguish between electricity that is generated, electricity that is transmitted through the network and electricity that is properly measured and accounted for.

Electricity passes through several stages before reaching consumers. It is generated at power plants, transported through transmission infrastructure and delivered through distribution networks or other authorized arrangements to customers.

At different points in this process, operators must measure how much electricity enters and leaves the system. Those measurements help determine consumption, billing, revenue collection and the financial obligations of the various market participants.

When the electricity recorded as entering a section of the network does not match the amount accounted for at the other end, an unexplained gap can emerge.

Some differences may result from technical losses, which occur naturally when electricity moves through wires and equipment. Other discrepancies can arise from faulty meters, incorrect readings, equipment problems, data errors or weaknesses in billing and collection systems.

In some cases, electricity theft or deliberate interference with metering equipment may also be responsible.

The investigation along the Ikorodu–Sagamu corridor is intended to determine which factors explain the reported discrepancy and how much each may contribute to the estimated financial impact.

The ₦120 billion figure should therefore be treated as an estimate of the value of unaccounted-for energy under investigation, not as a confirmed amount of stolen money or a final finding of financial wrongdoing.

That distinction matters because the outcome will determine what corrective action is appropriate, whether revenue can be recovered and whether any individuals or organisations should face sanctions.

Why the Ikorodu–Sagamu Corridor Matters

The Ikorodu–Sagamu axis, spanning parts of Lagos and Ogun states, is an important industrial corridor. Manufacturing and other large electricity-consuming businesses operating in the area depend on power to run machinery, maintain production and support day-to-day operations.

As industrial activity expands, accurate measurement of electricity consumption becomes increasingly important.

Large electricity users can account for substantial amounts of energy. If the electricity supplied to them is not properly measured and accounted for, the resulting discrepancies can affect billing, revenue collection and confidence in the market.

The corridor is therefore an important test of how monitoring technology, metering infrastructure and enforcement can work together to improve accountability.

NISO has said its monitoring systems have been enhanced since 2024 to provide greater visibility into electricity flows and consumption patterns across the national grid. The anomalies identified along the corridor prompted a more detailed review.

The investigation reportedly includes checks on reference metering infrastructure, physical inspections of industrial substations and electrical installations, and technical assessments of the systems used to measure electricity.

Some facilities have also received formal notices based on preliminary findings, requiring explanations, corrective action or further investigation.

These steps are important because reliable electricity measurement must be supported by verifiable records, properly functioning equipment and procedures that allow discrepancies to be resolved fairly.

If the investigation identifies weaknesses in the way electricity is measured or recorded, correcting them could help improve the management of the corridor and provide lessons for other parts of the power system.

How Electricity Losses Affect the Power Market

Nigeria’s electricity market depends on a chain of organisations that must coordinate to supply power and account for its use. These include generation companies, transmission and system operators, distribution companies, eligible customers and other market participants.

Each has responsibilities within the electricity value chain, and the market needs reliable information about electricity flows to determine the amounts supplied, consumed and billed.

Where substantial quantities of electricity cannot be properly accounted for, it becomes harder to establish whether bills accurately reflect consumption and whether the relevant parties are receiving or paying the correct amounts.

This can create financial uncertainty for market participants and weaken confidence in the integrity of electricity transactions.

The financial consequences depend on the actual cause of the discrepancies. If the investigation establishes that electricity was consumed but not properly billed, the relevant market participants may need to correct records and pursue recovery in accordance with applicable rules. If technical faults or metering errors are responsible, repairs, re calibration and better measurement procedures may be required.

Where deliberate wrongdoing is proven, enforcement may also be necessary.

However, recovering the estimated value of the unaccounted-for energy cannot be assumed until the investigation establishes what happened and which corrective measures are justified.

The broader objective should be to ensure that electricity supplied through the system is measured accurately, attributed to the appropriate parties and billed fairly.

What Does This Mean for Manufacturers and Other Businesses?

For businesses operating in industrial areas, electricity is a major operating consideration. It powers machinery, supports production schedules and affects the cost of manufacturing goods and providing services.

Reliable power supply can help companies plan production, manage expenses and compete more effectively. But electricity reliability must be supported by a market in which consumption is measured correctly and charges are transparent.

The investigation could therefore matter to manufacturers in several ways.

First, accurate metering can help businesses understand their actual consumption and verify that their electricity bills reflect the energy used. This is particularly important for large facilities with significant electricity demand.

Second, a more transparent electricity market can reduce disputes over consumption records and billing. Where discrepancies occur, clear technical evidence and established procedures can help resolve them.

Third, stronger accountability could improve confidence among investors and businesses that depend on reliable electricity arrangements. Investment decisions are easier to make when companies can understand their energy costs and the rules governing supply.

Nevertheless, the investigation should not be interpreted as proof that industrial consumers are collectively responsible for the reported gap. The corridor contains multiple market participants, and the review must determine where the discrepancies originated.

Businesses should be held accountable for any violations established through a fair process, while technical problems and administrative failures should be addressed according to their actual causes.

Fairness is important because the objective is not simply to punish offenders. It is to create an electricity market in which consumers pay appropriately for the power they use and service providers are held to clear standards.

Can Better Monitoring Improve Electricity Accountability?

Technology-based monitoring is central to the investigation because it can help operators identify unusual electricity flows and discrepancies that may be difficult to detect through routine checks alone.

When monitoring systems are supported by accurate meters and reliable data, operators can compare the amount of electricity recorded at different points in the network. Significant differences can then trigger further technical examination.

This can make it easier to identify possible faults, investigate unusual consumption patterns and determine whether records need to be corrected.

However, monitoring technology is not enough on its own.

A system can identify a discrepancy, but investigators still need to determine why it occurred. Metering equipment must be properly installed, maintained and calibrated. Data must be accurate, records must be available for review, and the agencies responsible for enforcement must have clear procedures for responding to confirmed violations.

There must also be a way for affected customers and market participants to challenge findings they believe are incorrect.

The investigation will be more meaningful if it produces verifiable explanations for the reported losses, identifies the specific weaknesses that allowed them to occur and establishes practical measures to prevent a recurrence.

If successful, the approach could demonstrate how better monitoring and energy accounting can strengthen accountability beyond a single industrial corridor.

The Link Between Electricity Accountability and Sustainability

Electricity losses may appear to be a technical issue, but they also have economic and social implications.

A financially sustainable electricity market needs to measure and account for energy accurately. Persistent discrepancies can weaken revenue collection, complicate investment decisions and increase uncertainty across the sector.

When the market struggles to account for the electricity supplied, it becomes harder to determine where improvements are needed and how costs should be allocated fairly.

For businesses, electricity costs and reliability influence productivity, competitiveness and decisions about expansion. For workers and communities, the performance of industrial businesses can affect employment, household income and access to economic opportunities.

There is also an environmental dimension. Improving the efficiency of electricity networks and reducing avoidable losses can help make better use of available power resources. However, the environmental benefit in this particular case cannot be quantified without establishing the source of the discrepancy and the measures required to address it.

From a sustainability perspective, the important issue is whether the electricity sector can deliver services more efficiently while maintaining transparency, fairness and accountability.

This requires more than identifying losses. It requires institutions to explain what happened, correct weaknesses and demonstrate that the improvements are producing measurable results.

What Should Happen After the Investigation?

The next steps will determine whether the probe produces lasting improvements or remains a one-time intervention.

First, the findings should clearly explain the source of the discrepancies. Investigators should distinguish between technical losses, equipment faults, metering errors, operational problems and any deliberate violations established by the evidence.

Second, the relevant market participants should receive clear information about findings that affect them, subject to applicable legal and regulatory requirements. Where disputes arise, there should be procedures for reviewing evidence and resolving them fairly.

Third, any confirmed metering or infrastructure problems should be corrected. That may involve repairing equipment, re-calibrating meters, strengthening inspection procedures or improving how electricity data is recorded and reconciled.

Fourth, proven violations should attract appropriate action under the applicable rules. Enforcement should be based on evidence and applied consistently, regardless of the size or influence of the organization involved.

Finally, the government and electricity sector institutions should communicate what the investigation achieves. The public and market participants need to know whether the discrepancies have been explained, what measures have been introduced and whether the same problems are recurring.

These steps would help turn the investigation into an opportunity to improve electricity market governance.

Measuring Progress Beyond the ₦120 Billion Figure

The estimated financial value of the unaccounted-for energy has drawn attention to the case, but the success of the response should be judged by more than the headline amount.

Important indicators include improvements in metering accuracy, the reduction of unexplained differences between electricity supplied and recorded consumption, the resolution of billing disputes and compliance with established electricity market rules.

Authorities should also assess whether corrective measures prevent similar discrepancies from recurring and whether electricity market participants can access reliable information about their consumption and obligations.

Any revenue recovered should be reported with a clear explanation of how the amount was established and the basis for recovery. This would help distinguish estimated losses from confirmed liabilities and money actually recovered.

Transparent reporting can also help build confidence among businesses, consumers and investors. It gives stakeholders a clearer picture of whether enforcement is working and whether electricity market institutions are addressing the underlying problems.

The lesson is that accountability should not end when an investigation is announced. It should continue through the publication of credible findings, the implementation of corrective measures and the monitoring of results.

Conclusion: Electricity Supply Must Come With Accountability

The Federal Government’s investigation into the estimated ₦120 billion in unaccounted-for electricity along the Ikorodu–Sagamu corridor highlights the importance of accurate measurement and transparency in Nigeria’s power sector.

The reported discrepancy is significant, but its full meaning will depend on the investigation’s findings. Until the causes are established, the amount should not be treated as confirmed theft or attributed to any particular business.

What matters now is whether the process can explain where the discrepancy came from, establish responsibility where evidence supports it and correct the weaknesses that allowed the gap to emerge.

For Nigeria’s industrial sector, a more accountable electricity market could support fairer billing, clearer operating costs and greater confidence in electricity arrangements. For the wider economy, improved energy accounting could help strengthen the financial discipline needed to sustain the power system.

Ultimately, reliable electricity and accountability must go together. The country needs a system in which electricity flows are properly measured, customers are charged fairly, market participants meet their obligations and institutions explain their decisions.

The real measure of success will not simply be the amount investigated, but whether the process leads to better electricity management, stronger public confidence and lasting improvements in the way Nigeria accounts for its power.
