Eligible Customer in Nigeria: A Step-by-Step Guide for Businesses (2026)

If your business consumes significant amounts of electricity, you may be paying more than you need to. Nigeria's Eligible Customer regulations allow qualifying businesses to buy power directly from generation companies rather than through distribution companies, often at more competitive rates.

This guide walks you through who qualifies, what documents you need and how the process works step by step under the NERC Eligible Customer Regulations 2024.

What Is an Eligible Customer?

An Eligible Customer is an end-user of electricity approved by the Nigerian Electricity Regulatory Commission (NERC) to purchase power directly from a supplier of their choice, rather than being restricted to the local distribution company (DisCo).

The Eligible Customer regime was introduced under the Electricity Act 2023 to accelerate competition in Nigeria's electricity market. It gives large energy consumers the freedom to negotiate their own supply terms, often securing lower costs and more reliable power.

Who Qualifies?

The NERC Eligible Customer Regulations 2024 set minimum consumption thresholds. Your business qualifies if it falls into one of these categories:

Category 1: Point-to-Point Connection

An end-user whose average or planned consumption is not less than 6 MWh/h over 90 days, directly connected to a generation company's facility via a metered 33kV delivery point.

Category 2: New Connection to 33kV Network

An unconnected end-user whose planned average consumption is not less than 10 MWh/h over 90 days, to be connected to a metered 33kV delivery point on the DisCo's distribution network.

Category 3: Existing DisCo Customer Transitioning

An end-user currently connected to a DisCo whose average consumption is not less than 10 MWh/h over 90 days, connected to a metered 33kV delivery point on the distribution network.

Category 4: Existing Customer on Transmission Network

An end-user whose average consumption is not less than 20 MWh/h over 90 days, connected to a metered 132kV or 330kV delivery point on the transmission network.

Category 5: New Connection to Transmission Network

An unconnected end-user whose planned average consumption is not less than 20 MWh/h over 90 days, to be connected to a metered 132kV or 330kV delivery point on the transmission network.

Key insight: The 6 MWh/h threshold for Category 1 is the most accessible route. This roughly translates to a facility with a connected load of around 6,000 kWh over 24 hours, which many manufacturing plants, hotels, hospitals and large commercial complexes easily exceed.

Documents You Will Need

Before applying, gather the following:

1. Letter of intention to switch supplier (if switching from an existing supplier)
2. Evidence of consumption load profile -- your metered consumption data over one year
3. Evidence of uncontracted capacity from your proposed supplier
4. Utility bills for the preceding six months
5. Letter of introduction from your bankers and other financial support documents
6. Letter of clearance from your current DisCo confirming non-indebtedness
7. Evidence of a minimum 3-month notice to your current supplier
8. Evidence of security deposit or letter of credit covering 3 months of energy delivered and market administration charges

The Step-by-Step Application Process

Step 1: Engage an Energy Advisor

Before filing with NERC, work with an energy advisory firm like Zenithwatts to assess your eligibility, evaluate available suppliers and prepare your application. This upfront investment saves months of back-and-forth with the regulator.

Step 2: Prepare Your Load Profile

NERC requires a detailed load profile confirming your metered consumption over the preceding year. If you do not have consumption history, a connected load analysis of your facility will be conducted and reviewed after six months of operations.

Step 3: Identify a Supplier

Eligible Customers may procure energy from any licensed generator (GenCo) or electricity trader that has tradable capacity beyond its already contracted volumes. Your supplier must provide evidence of excess capacity.

Step 4: File Application with NERC

Submit your application with all required documentation. NERC will review your load profile and the proposed supplier's uncontracted capacity. The Commission must respond within 30 working days from receipt of a complete application.

Step 5: NERC Reviews and Issues Eligibility Status

In the first stage, NERC evaluates your load profile and the supplier's capacity. In the second stage, after confirming eligibility, you submit agreed drafts of transaction documents for review.

Step 6: Negotiate and Execute Agreements

Once NERC grants Eligible Customer status, you execute:

• Power Purchase Agreement (PPA) with your chosen supplier
• Transmission Use of System Agreement (TUoS) if connecting to the transmission network
• Distribution Use of System Agreement (DUoS) if connecting through a DisCo's network
• Supplier of Last Resort Agreement as required by regulation

Step 7: Begin Supply

After all agreements are executed and the Independent System Operator confirms compliance with connection requirements, you begin receiving power from your chosen supplier.

The Cost Transition Charge (CTC)

One important financial consideration is the Cost Transition Charge. When a customer switches from a DisCo to a new supplier, the DisCo may be entitled to a CTC to recover revenue losses.

The CTC is calculated as:

CTC per kWh = Actual tariff payable by the EC applicant minus (Weighted average tariff for Non-MD customers of the DisCo multiplied by collection efficiency for the DisCo's Non-MD customers)

The monthly CTC is computed by multiplying the CTC per kWh by the customer's average monthly energy billed during the 90 days preceding the application.

Important: The CTC methodology means that businesses switching from DisCos with lower collection efficiencies may face higher transition charges. An experienced energy advisor can model this cost for your specific situation.

How Long Does the Process Take?

From initial engagement to first power delivery, the typical timeline is:

Phase	Duration
Preparation and load profiling	2 to 4 weeks
NERC application review	30 working days
Agreement negotiation and execution	4 to 8 weeks
System connection and commissioning	2 to 6 weeks
Total estimated timeline	3 to 6 months

What Businesses Typically Qualify

Based on NERC data and market experience, businesses that commonly qualify include:

• Manufacturing plants with continuous production lines
• Large hotels and hospitality chains with significant air conditioning and kitchen loads
• Hospitals and healthcare facilities requiring reliable 24/7 power
• Data centres with high and consistent power demand
• Commercial real estate complexes with large common area loads
• Breweries and beverage producers with energy-intensive processes
• Cement and heavy industry operations

Why Businesses Choose Eligible Customer Supply

The primary advantages of Eligible Customer status include:

1. Competitive pricing -- negotiate directly with suppliers for rates below standard DisCo tariffs
2. Supply reliability -- contractual guarantees on hours and quality of supply
3. Choice of supplier -- freedom to switch suppliers with 3 months' notice
4. Customised supply terms -- negotiate pricing, quantity and time of supply to match your operations
5. Access to excess generation capacity -- tap into GenCo capacity that would otherwise be curtailed

Common Mistakes to Avoid

• Applying without a proper load profile -- NERC will reject applications without adequate consumption data
• Underestimating the CTC -- factor transition charges into your cost modelling from the start
• Choosing the cheapest supplier without checking capacity -- ensure the GenCo has genuine uncontracted capacity
• Skipping the DisCo clearance -- your current DisCo must confirm non-indebtedness before you can switch
• Not engaging an energy advisor -- the regulatory process is complex and errors cause significant delays

Next Steps

If your business consumes 6 MWh/h or more and you want to explore whether Eligible Customer supply could reduce your energy costs, the first step is an energy assessment.
