Building measurable, cost-reflective tariffs in state electricity markets (2) Consumers cannot be protected from what regulators cannot measure

One of the primary responsibilities assigned to electricity regulators is consumer protection. Regulatory commissions at both federal and state levels routinely speak of safeguarding consumers from unfair tariffs, poor service quality, estimated billing, arbitrary disconnections, and utility operational inefficiencies.

Yet a fundamental question is rarely asked: How can a regulator protect consumers from problems it cannot accurately measure? 

For years, electricity regulation in Nigeria has focused heavily on tariffs, licensing, compliance directives, and dispute resolution. While important, these functions address the symptoms of market failure rather than its root cause: information asymmetry. 

Utilities possess far more information about network performance than regulators. Regulators possess more information than consumers. Consumers possess the least information of all. In such an environment, consumer protection remains purely reactive. The solution is simple in principle: Consumer protection must begin with measurement.

The myth of regulation without verification
Regulations do not protect consumers by their mere existence; they protect consumers only when compliance can be independently verified. 

A rule requiring reliable supply is meaningless if supply duration is not measured. 

A rule requiring fair billing is meaningless if energy consumption is not measured. 

A rule requiring loss reduction is meaningless if network losses are not measured. Without measurement, regulation remains little more than aspiration.

The estimated billing problem
Few issues have damaged consumer trust in Nigeria’s power sector as deeply as estimated billing. Consumers complain that bills bear little relation to actual consumption, while utilities argue that estimated billing is unavoidable due to metering gaps. 

Where there is no measurement, there can be no trust. A meter is not merely a billing instrument; it is a consumer protection device. It protects utilities from underpayment, protects consumers from arbitrary over-billing, and establishes a transparent baseline for both parties.  However, customer metering alone is only part of the solution. 

Why customer metering alone is not enough

An effective regulator must measure what happens before electricity reaches the end user. Regulators must be able to track:

• How much energy entered a specific feeder?
• How much reached distribution transformers?
• How much was delivered to customers versus billed and collected?

Without answers to these questions, regulators cannot pinpoint where losses occur or who should be held accountable. This is why modern power markets rely on comprehensive energy accounting rather than customer meters alone. 

The case for feeder-level measurement
Electricity is delivered—and experienced—at the feeder level. Losses occur on feeders, and revenues are generated on feeders. Yet regulatory decisions continue to rely on utility-wide averages.

Aggregating performance hides critical realities:
One feeder may receive 20 hours of daily supply with a 95 percent collection efficiency and minimal losses. Another feeder under the same utility may receive under eight hours of supply, with rampant losses and dismal collection rates.

Averaging these figures masks both excellence and operational failure. State regulators must make feeder-level energy accounting a foundational obligation, transforming every feeder into an audit-able business unit.

A comprehensive protection architecture
To deliver genuine consumer protection, emerging state regulators must establish a multi-tiered measurement architecture:

• Customer metering: Functional meters for all end users.

• Distribution transformer metering: Metering at localised step-down points.

• Feeder metering: Boundary metering across critical supply points.

• Injection substation metering: Independent measurement of bulk energy entering the local grid.

• Regulatory audit meters: Independent meters deployed strategically by regulators to audit utility-supplied data. Trust is important, but verification is indispensable. 

Transparency as active protection
Measurement must be paired with visibility. Regulators should mandate public dashboards displaying feeder-specific metrics: supply hours, outage frequencies, collection rates, technical and commercial losses, and maintenance schedules.

When performance data is published transparently, consumer protection becomes proactive. Consumers can verify service levels themselves, forcing utilities to remain accountable to the public as well as the regulator. Transparency often accomplishes what enforcement struggles to achieve.

The first investment state regulators must make
Newly established state electricity regulatory commissions will face immediate political pressure to conduct tariff reviews. That pressure should be resisted.

 
The first major investment should not be a tariff study; it should be a measurement system. The first regulatory directives should not focus on pricing, but on data collection standards, feeder accounting, metering mandates, and performance reporting.

Once accurate measurement exists:

• Consumer protection becomes enforceable. 

• Utility oversight becomes straightforward.

• Investment risk is mitigated.

• Tariff determination becomes objective.

Conclusion
Consumer protection is often framed as a legal or administrative responsibility. In reality, it is fundamentally a measurement responsibility.

Consumers cannot be protected from over-billing, poor service, or utility waste if those elements are not accurately quantified. For Nigeria’s emerging state regulators, the strongest consumer protection framework is not a complex rule book—it is an unassailable measurement system.

Because regulators cannot protect consumers from what they cannot measure. And they cannot regulate what they cannot see.
