How to Upgrade Your STS Meter Before the TID Rollover


All prepaid electricity meters around the world, including those in Nigeria, currently operate on software that has a scheduled expiration date of November 24, 2024. This is known as the TID Rollover.

When this happens, the current software on all prepaid meters will no longer be supported. All STS model prepaid meters on the Ikeja Electric (IE) network need to be upgraded before this date, otherwise, they will lose the functionality to add credit and maintain electricity supply after November 1, 2023, when IE will initiate its TID Rollover process.

This article provides comprehensive information on how IE customers with STS prepaid meters can complete the required upgrade before the TID Rollover occurs.

Identifying If You Have an STS Prepaid Meter

To identify if you have an STS model meter that requires upgrading, check if 20-digit token numbers are generated each time you purchase and add credit to your meter.

If your meter does generate these 20-digit tokens, then it is an STS model that needs to be upgraded before the November 2024 TID Rollover.

Overview of the STS Meter Upgrade Process

The upgrade process consists of two key steps that all STS prepaid meter customers must complete:

  1. Validate your National Identification Number (NIN)
  2. Initiate the STS meter upgrade process

Both of these steps must be completed before November 1, 2023 in order to maintain electricity supply. Details on each step are provided below.

Step 1: Validating Your NIN

To begin, you need to validate and link your National Identification Number (NIN) to your STS meter number. This provides the verification required to generate the necessary tokens for upgrading your meter.

Follow these instructions to validate your NIN:

  • Go to the IE NIN validation website:
  • Click on the button “Link Your NIN and Meter”
  • Input your phone number, NIN, and email address into the required fields.
  • Carefully verify that the NIN details returned are correct, then click “Next” to proceed.
  • Input your meter number and the verification code sent to your email address.
  • Click the “Submit” button to complete linking your NIN to your meter.

Please note the following important points about NIN validation:

  • Each meter can only have one NIN linked to it. The exception is landlords who have multiple meters, as they can use their individual NIN for all meters.
  • Your personal information is kept completely confidential by IE throughout this process.

Once you have successfully validated your NIN, you can proceed to Step 2.

Step 2: Upgrading Your STS Meter

Upon completion of Step 1, you are now eligible to initiate the upgrade process for your STS meter.

Beginning November 1, 2023, when you purchase and add credit to your meter, you will receive three separate sets of 20-digit token numbers:

  1. Key Change Token 1 (KCT 1): This token resets and wipes your meter’s current software.
  2. Key Change Token 2 (KCT 2): This token upgrades your meter to the new STS software platform.
  3. Energy Token: This token adds the credit you have purchased to your meter.

Pls note if you didn’t get 3 codes the first time you want to recharge- visit to generate the first 2 codes

To successfully upgrade your STS meter, you must input these tokens in the proper sequence:

A) Enter Key Change Token 1 FIRST. This will reset and wipe the old software from your meter.

B) Enter Key Change Token 2 SECOND. This will upgrade your meter to the new STS software.

C) Enter the Energy Token LAST. This adds and applies the credit you have purchased to your upgraded meter.

It is crucial to input the tokens in the proper order of KCT 1, KCT 2, and then the Energy Token for the upgrade to complete successfully.

Please note that only customers who have completed the NIN validation in Step 1 will receive the Key Change Tokens (KCT 1 and KCT 2) required to initiate the upgrade. The Energy Token to add credit is provided to all customers as usual.

Failure to upgrade your STS meter before November 1, 2023 will result in disruption of electricity service and inability to add further credit.
