What NEPA/DisCo Band Are You On? Nigeria Electricity Tariff Bands Explained

If your neighbour pays a different electricity rate from you, the reason may not be meter fraud or an incorrect bill. In Nigeria, electricity customers are grouped into Band A, Band B, Band C, Band D, or Band E according to the minimum number of supply hours their distribution network is expected to receive.

The Nigerian Electricity Regulatory Commission, or NERC, introduced the Service-Based Tariff system to connect electricity prices with service quality. Under the system, Band A represents a minimum of 20 hours of supply daily, while Band E represents a minimum of four hours. Your actual tariff also depends on your DisCo, customer class, meter status, feeder classification, tariff order, and applicable taxes or charges.

What the NERC bands mean

The phrase “NEPA band” is commonly used in everyday conversation, but NEPA no longer operates as Nigeria’s retail electricity distributor. Your electricity is supplied and billed through a licensed Distribution Company, commonly called a DisCo, while NERC regulates the electricity market.

The band describes the expected service level for the feeder or customer cluster, not simply the street name or the type of house. A feeder is part of the electricity distribution network serving a defined area. Two compounds on the same road can therefore receive power from different feeders and fall into different bands.

NERC states that the band is shown on the electricity bill issued by the DisCo or on the vending receipt for prepaid customers. The band is not determined by whether you live in a self-contained apartment, a duplex, a rented room, or a business premises. It is linked primarily to the network service classification.

Why your neighbour’s bill differs

There are several legitimate reasons two electricity customers may receive different bills even when they live close to one another.

Different feeders

The most common explanation is that the homes are connected to different feeders. One feeder may be classified as Band A and another nearby feeder as Band C or Band D.

For example, a house supplied by a Band A feeder may receive a tariff of ₦200 per kilowatt-hour, while a nearby house supplied by a Band C feeder may receive a lower rate. The precise amount depends on the applicable DisCo tariff order and customer category.

The distance between houses does not determine the band. The network arrangement does.

Different DisCos

Nigeria has several DisCos serving different geographical areas. Examples include:

• Eko Electricity Distribution Plc.
• Ikeja Electric Plc.
• Abuja Electricity Distribution Plc.
• Ibadan Electricity Distribution Plc.
• Enugu Electricity Distribution Plc.
• Benin Electricity Distribution Plc.
• Kaduna Electricity Distribution Plc.
• Kano Electricity Distribution Plc.
• Jos Electricity Distribution Plc.
• Port Harcourt Electricity Distribution Plc.
• Yola Electricity Distribution Plc.

Each DisCo operates under tariff orders and regulatory arrangements applicable to its franchise area. Consequently, two customers in different states—or even different areas served by different DisCos—may not pay the same amount per unit.

Different customer classes

Electricity tariffs may also differ according to customer classification. A household customer is not necessarily billed under the same tariff category as a shop, office, factory, school, or other commercial premises.

The bill or vending receipt may identify the tariff class, band, rate per kilowatt-hour, energy charge, fixed charge where applicable, VAT, debt adjustment, or other approved items.

Metered versus estimated billing

A prepaid customer usually buys electricity in units, while an unmetered customer may receive a monthly bill based on NERC’s approved estimated-billing methodology and applicable energy caps.

These two customers may have different billing experiences even if they use similar appliances. A prepaid customer sees the number of units purchased after payment. An unmetered customer receives a bill calculated using an approved methodology rather than a direct meter reading.

NERC states that unmetered customers should not be billed above the applicable energy cap. The Commission also provides a process for customers to contest estimated bills.

Different consumption levels

A tariff rate is not the same thing as total electricity consumption. One customer may pay ₦100 per kWh and use 300 kWh, while another pays ₦200 per kWh and uses only 100 kWh.

Customer A has the lower unit rate but the higher energy bill because the customer used three times as many units.

How to read your electricity bill

A typical electricity bill or prepaid receipt may contain several important details:

1. Customer account or meter number.
2. DisCo name.
3. Feeder or supply classification.
4. Tariff band.
5. Tariff rate per kWh.
6. Energy units purchased or consumed.
7. VAT or other approved statutory charges.
8. Outstanding balance or debt adjustment.
9. Payment reference.
10. Date of transaction or billing period.

For a prepaid meter, the receipt may show the amount paid, the number of units credited, and the rate used in the calculation. For a postpaid account, the bill may show previous and current meter readings, consumption, tariff rate, total energy charge, and other charges.

NERC explains that you can estimate the effective tariff by dividing the amount paid by the units received, but VAT should be deducted when calculating the basic energy tariff.

How to calculate prepaid electricity units

The basic calculation is:

[ \text{Energy charge} = \text{Units consumed} \times \text{Tariff per kWh} ]

For example, if your home uses 150 kWh in a billing period and your tariff is ₦206.80 per kWh:

[ 150 \times ₦206.80 = ₦31,020 ]

If VAT or another approved charge applies, the final amount paid may be higher than the basic energy charge. Your receipt may also include an outstanding debt recovery, adjustment, or other item authorised under the applicable tariff framework.

Example with VAT

Assume:

• Electricity consumption: 150 kWh.
• Approved energy tariff: ₦206.80 per kWh.
• VAT assumption for illustration: 7.5%.

Basic energy charge:

[ 150 \times ₦206.80 = ₦31,020 ]

Illustrative VAT:

[ ₦31,020 \times 7.5% = ₦2,326.50 ]

Illustrative total:

[ ₦31,020 + ₦2,326.50 = ₦33,346.50 ]

This is a calculation example, not a universal bill format. The exact amount depends on the current tariff order, tax treatment, DisCo billing system, customer category, and any approved adjustments shown on the receipt.

You can use ToolBase’s electricity-bill-units-calculator to estimate units from a naira payment or estimate the cost of a given number of units.

What “units” mean

Electricity units are generally measured in kilowatt-hours, written as kWh. One unit on a prepaid electricity meter normally represents one kilowatt-hour of energy.

The energy used by an appliance can be estimated with:

[ \text{kWh} = \frac{\text{Wattage} \times \text{Hours used}}{1,000} ]

For example, a 100-watt fan running for 10 hours uses approximately:

[ \frac{100 \times 10}{1,000} = 1 \text{ kWh} ]

If electricity costs ₦200 per kWh, the energy component for that use is:

[ 1 \times ₦200 = ₦200 ]

Actual household consumption depends on appliance efficiency, voltage conditions, operating cycles, standby consumption, and the accuracy of the meter.

For a larger household, the combined monthly consumption of refrigerators, freezers, fans, air conditioners, water pumps, televisions, pressing irons, lighting, and cooking appliances can be substantially higher than the consumption of a single occupant using only lights, a phone charger, and a fan.

Why prepaid units can look different

Customers sometimes compare the naira amount paid with the units received and conclude that the tariff rate is inconsistent. Several factors can affect the result:

• VAT may be deducted or included in the transaction calculation.
• An approved debt recovery may reduce the units credited.
• A previous balance may be settled from the payment.
• The customer may have received a tariff adjustment.
• The receipt may include a fixed or service charge.
• The transaction may involve a correction or meter update.
• The customer may have moved between tariff classifications.

The correct starting point is the receipt breakdown, not only the final number of units. If the receipt does not explain the calculation, the customer can request clarification from the DisCo’s customer service unit.

What happens when Band A service falls short?

The band is a service commitment, not a permanent label guaranteeing uninterrupted electricity every hour. NERC’s tariff FAQ states that where a DisCo fails to deliver the minimum service associated with a band, the Commission can evaluate performance over a 60-day period. After verification, rates for customers in the affected cluster may be adjusted in line with the service delivered.

This means a feeder’s classification and tariff can be reviewed when actual supply performance does not meet the required threshold. Customers can keep records of supply interruptions, meter readings, payment receipts, and complaints because these documents help establish the facts of a billing or service dispute.

A practical record may include:

A personal log does not replace NERC’s verification process, but it can provide useful supporting information when communicating with a DisCo.

Estimated billing and energy caps

Estimated billing applies where a customer is not metered or where an approved billing process is used in a particular circumstance. NERC’s billing guidance states that unmetered customers must be billed transparently and that DisCos cannot exceed the energy cap applicable to the relevant feeder or customer category.

Where a meter becomes faulty, NERC says a replacement meter should be installed and a customer should not be placed on estimated billing simply because the DisCo failed to replace the meter. If replacement cannot be completed within a billing period, the average of the previous three months’ billing or vending may be used for determining consumption in the relevant situation.

The treatment of a disputed bill is different from a bill that has not been questioned. NERC’s consumer-rights guidance says an unmetered customer disputing an estimated bill may pay the last undisputed bill while the contested amount goes through the dispute-resolution process.

What to do about an incorrect bill

The ordinary complaint route begins with the DisCo’s Customer Complaints Unit, often called the CCU. A complaint can relate to:

• Incorrect tariff band.
• Wrong meter number or account details.
• Estimated billing above the applicable cap.
• Unexplained debt.
• Faulty meter.
• Failure to provide a meter.
• Incorrect customer classification.
• Disconnection without proper notice.
• Failure to apply an approved tariff adjustment.

Keep copies of:

1. The disputed bill or vending receipt.
2. Proof of payment.
3. Meter photographs and readings.
4. Your account or meter number.
5. Previous bills.
6. Written communication with the DisCo.
7. A record of supply hours where service quality is disputed.

NERC’s published complaint procedure directs customers to begin with the DisCo’s CCU and escalate unresolved matters to the relevant NERC Consumer Forum.

However, the regulatory structure changed in 2026 for states with active state electricity regulators. NERC announced that intrastate electricity oversight had transitioned to state regulators in 15 states: Abia, Anambra, Bayelsa, Edo, Ekiti, Enugu, Imo, Kogi, Lagos, Nasarawa, Niger, Ogun, Ondo, Oyo, and Plateau. Consumers in those states were directed to contact their respective State Electricity Regulator for billing, metering, service-quality, and operational disputes.

Customers outside those jurisdictions should verify the current complaint channel with their DisCo and NERC, because electricity regulation can depend on the applicable state and market arrangement.

How to identify your actual band

Use this checklist:

• Check the tariff band printed on your latest bill.
• Check the tariff band on your prepaid vending receipt.
• Compare the feeder or tariff code with previous receipts.
• Confirm the DisCo serving your premises.
• Ask the DisCo to identify the feeder supplying your meter.
• Compare the stated tariff with the applicable tariff order.
• Record the approximate daily supply hours.
• Report a mismatch through the appropriate complaint channel.

Do not identify your band solely from the number of hours electricity happened to be available on one day. NERC’s classification uses service commitments and performance assessment over time, rather than a single evening or weekend.

How to compare your bill with a neighbour’s

A meaningful comparison requires more than comparing the final naira amount. Compare these fields:

If the two properties have different bands, customer classes, or consumption levels, different bills may be expected. If all fields are identical but the charges differ, the receipts can be submitted to the DisCo for reconciliation.

For broader household budgeting, ToolBase’s electricity-bill-units-calculator can help convert expected usage into an estimated naira amount. You can also use the monthly-budget-planner to place electricity spending alongside rent, transport, food, data, and other household costs.

The legal and regulatory basis

NERC’s consumer-protection responsibilities originated under the Electric Power Sector Reform Act 2005, which was later repealed and replaced by the Electricity Act 2023. NERC identifies the Electricity Act 2023 as the current legal foundation for its regulatory role, including licensing, technical and economic regulation, customer rights, and tariff determination.

Under the current framework, the Commission regulates service standards and tariffs while DisCos provide distribution services to customers in their licensed areas. The Service-Based Tariff framework classifies customers according to minimum supply-hour commitments, while tariff orders specify the rates and conditions applicable to the relevant DisCo and customer category.

For consumers, the practical implication is that a bill should be assessed using the details of the actual customer account—not a general rate circulating on social media.

Conclusion

Your neighbour’s electricity bill can differ from yours because of a different feeder, NERC band, DisCo, customer class, meter status, consumption level, VAT treatment, debt adjustment, or estimated-billing arrangement. Check the band and tariff rate on your bill or prepaid receipt, calculate the energy component using units multiplied by the applicable naira-per-kWh rate, and use the official complaint route when the billing details or service level appear inconsistent.
