Loading a prepaid meter in Nigeria means entering a 20-digit token — purchased for as little as ₦ 500 — directly on the keypad of your meter to credit it with electricity units (kWh). Whether your meter belongs to IKEDC, EKEDC, AEDC, PHED, KEDCO, or any other DisCo, the loading process follows the same standard. This guide covers every household type: single tenants, NYSC corpers in rented rooms, parents managing a family compound, and small-business owners who cannot afford a blackout during business hours.

What You Need Before You Load

Before you punch a single digit, make sure you have the following ready:

• Your meter number (MSN): printed on the front panel of the meter, usually 11–13 digits long. You need this to purchase a token.
• A valid 20-digit token: received via SMS, email, WhatsApp, or printed receipt after purchase.
• Power supply to the meter: the keypad backlight and display must be active. If your meter is completely dead (tamper or credit exhausted), you may need an emergency/tamper token first — contact your DisCo.
• Reading glasses or phone torch if needed: meter keypads are often in dark corridors or outside walls.

How to Load a Prepaid Meter: Step-by-Step

The process is the same across nearly all STS-compliant prepaid meters in Nigeria (Conlog, Hexing, Itron, Landis+Gyr, Inhemeter, etc.).

Step 1 — Wake the Meter Display

Press any key on the keypad once. The LCD screen should light up and show your current unit balance. If the display reads 0.0 kWh or shows a low-credit warning, that confirms you need to load immediately.

Step 2 — Enter the 20-Digit Token

Type the 20 digits exactly as they appear on your receipt or SMS — no spaces, no dashes. Most meters accept input in one continuous sequence. Example format: 1234 5678 9012 3456 7890 entered as 12345678901234567890.

• If you make a typing error, look for a backspace / clear (C) key on the keypad and delete the wrong digit before continuing.
• On some Conlog meters, pressing # clears the entire entry so you can start fresh.

Step 3 — Press Enter (or #)

After the 20 digits are entered, press the Enter or # key (varies by brand). The meter will process the token for 3–10 seconds.

Step 4 — Confirm the Credit

A successful load displays one of the following messages depending on your meter brand:

• ACCEPTED — Conlog, Hexing
• CREDIT kWh followed by the units added — Itron, Landis+Gyr
• NEW CREDIT: XX.X kWh — Inhemeter

Your new balance (old units + newly purchased units) will then display on screen. The meter automatically reconnects power if it had tripped due to zero balance.

Common Prepaid Meter Error Codes and How to Fix Them

Do not panic if the meter rejects your token. These are the most frequent errors and their fixes:

"USED TOKEN" or "ALREADY USED"

This token has already been successfully loaded on this meter. Check your current balance — it may have been loaded earlier without your knowledge (by a landlord or family member). If the balance did not increase, contact your DisCo customer care with the token number and purchase receipt.

"INVALID TOKEN" or "REJECTED"

The token does not match your meter number. This usually happens when:

• You bought a token for a different meter number (double-check the MSN you provided at purchase).
• A digit was misread — the number 0 (zero) is often confused with the letter O on some receipt fonts.
• You purchased from an unofficial vendor who generated a fake token.

Solution: verify your meter number on the device, compare it with the MSN on your purchase receipt, and contact support if they do not match.

"TAMPER" Display

The meter has detected tampering (physical interference or a power surge event). A regular credit token will not work. You must first obtain a tamper clear token from your DisCo office — bring your meter number, national ID, and proof of address.

Meter Displays a Number But Power Doesn't Come On

The token loaded correctly but your main breaker or isolator switch is off. Check the breaker box inside your apartment and flip it back on. Also confirm your DisCo has not flagged your connection for disconnection due to outstanding charges on a previous postpaid account.

How to Buy a Prepaid Meter Token Online (Fastest Method)

Queuing at a DisCo customer-care office or a bank branch to buy electricity units wastes up to two hours of your day. Buying online takes under 60 seconds. Here is exactly how:

1. Visit a licensed vendor platform (such as ABS Vendor at absvendor.com) and log in or create a free account.
2. Select Electricity from the services menu.
3. Choose your DisCo (e.g., IKEDC, EKEDC, AEDC, PHED, KEDCO, JEDC, etc.).
4. Enter your 11–13 digit meter number (MSN) carefully. The platform will auto-fetch the account name registered to that meter — confirm it matches your landlord or account details.
5. Enter the amount in naira you want to purchase (minimum is usually ₦ 500, though some DisCos set their own floor).
6. Pay via card, bank transfer, or your wallet balance on the platform.
7. Your 20-digit token is delivered instantly via SMS and on-screen. Save the SMS — you may need to reload it later if you misplace a digit.

The entire process — from login to token-in-hand — typically takes under two minutes on a decent mobile connection.

Pro Tips to Maximise Your Electricity Units

Buying units is only half the equation. Making them last longer saves real money:

• Check your standing charge: every prepaid meter deducts a fixed daily standing charge (typically ₦ 7–₦ 40 per day depending on your tariff band). Even if you use zero appliances, units deplete. Load regularly in smaller amounts rather than one large lump sum to avoid large idle losses.
• Know your tariff band (A–E): Band A customers (20+ hours of supply) pay higher per-kWh rates than Band D or E. Knowing your band helps you calculate whether ₦ 2,000 should last a week or only three days in your area.
• Unplug idle appliances: phone chargers, TVs on standby, and old fridges are silent unit-drainers. A single 100W incandescent bulb switched to a 9W LED saves roughly 91% on lighting costs.
• Monitor your balance: press 07 then # on most Conlog meters, or 800 on Hexing meters, to display your current kWh balance without loading a token.
• Load at off-peak tariff windows if applicable: some DisCos are piloting time-of-use tariffs — check your DisCo's website to know if night-time loading gets you more units per naira.

Frequently Asked Questions

Can I load a prepaid meter without electricity supply from the DisCo?

Yes. The meter keypad is powered by a small internal capacitor or battery backup on most models. You can enter the token even when there is no grid supply — power will restore automatically once the DisCo restores your area, provided your balance is above zero.

What happens if I enter the wrong meter number when buying a token online?

The token generated is cryptographically tied to the meter number you provided. It will show "INVALID TOKEN" on the wrong meter and cannot be transferred. Contact the vendor immediately with your receipt — most licensed platforms can reverse the transaction if the token has not been used.

How many times can I enter a token before the meter locks?

STS-standard meters allow up to three failed entry attempts before triggering a temporary lockout. Wait about five minutes, then try again slowly and carefully. If the issue persists, contact your DisCo with your meter number and purchase receipt.

Is there a minimum amount I can load on a prepaid meter?

Yes. Most DisCos set a minimum vend amount of ₦ 500, though some set it as low as ₦ 200 for residential customers. The minimum is set by the DisCo, not the vendor platform you use to purchase.

Can one token be loaded on two different meters?

No. Each 20-digit token is mathematically generated for one specific meter serial number (MSN). Attempting to load the same token on a different meter will always return "INVALID TOKEN."

Why did my units reduce overnight even though I used nothing?

Your meter is deducting the daily fixed charge (service charge) mandated by NERC. This is separate from your energy consumption and is charged regardless of usage. It is displayed as a line item on your DisCo statement if you request one.

Loading a prepaid meter is straightforward once you understand the steps, but the real time-saver is buying your token online instead of queuing at a DisCo office or third-party kiosk.
