For many Kenyan households, buying electricity tokens is now part of everyday life. Just like airtime, power is purchased in advance through prepaid meters that deduct units as electricity is consumed. But despite the convenience, many customers still struggle to understand why the number of units received changes from one purchase to another.
One month, KSh500 may buy several units. Another time, the same amount appears to deliver far less electricity. The difference has sparked debate online, especially as households try to manage rising living costs.
How the Token System Works
The prepaid electricity system operates using a 20-digit token code generated after payment. Customers can purchase tokens using M-Pesa, bank apps, USSD services or the MyPower app.
Once payment is completed, the token is sent via SMS and entered into the prepaid meter keypad. The meter then loads electricity units automatically.
Unlike postpaid systems where customers receive monthly bills after consumption, prepaid meters disconnect power automatically once the purchased units are exhausted. This allows households to control usage and avoid debt accumulation.
The system also uses encrypted security technology to ensure each token is unique and tied to a specific meter.
Why Units Keep Changing
One of the main reasons customers receive different units for the same amount is Kenya’s tiered electricity pricing structure.
Electricity is charged based on monthly consumption levels. Households using lower amounts of power fall under subsidised tariff bands and therefore receive more units at lower rates. However, once consumption increases beyond certain thresholds, the price per unit rises significantly.
The first tariff category, commonly referred to as the lifeline band, offers the cheapest electricity rates for low-consumption households. Customers who exceed that limit move into higher pricing brackets where electricity becomes more expensive.
This explains why KSh500 purchased earlier in the month may provide more units compared to the same amount bought later after consumption rises.
Taxes, Levies and Fixed Charges
Apart from the tariff structure, several deductions also affect the final number of units customers receive.
Electricity purchases include taxes, fuel cost adjustments, inflation-related levies and monthly fixed charges. A standard fixed monthly charge is deducted regardless of how much electricity a household consumes.
Because of these deductions, smaller purchases sometimes appear to provide very few units, especially after taxes and adjustments are applied.
Understanding Key Change Tokens
Some customers occasionally receive two separate 20-digit codes after purchasing tokens. These are known as key change tokens.
The codes are part of security upgrades designed to improve encryption standards and prevent token fraud or duplication. Customers are required to enter the codes in the correct order before loading electricity units.
The prepaid meter system also contains a Token Identifier mechanism, which ensures a token cannot be reused once it has already been loaded.
Tips to Reduce Electricity Costs
Energy experts recommend monitoring household electricity consumption carefully to avoid quickly moving into higher tariff bands.
Using energy-saving bulbs, switching off unused appliances and spreading out heavy electricity usage can help households manage costs more effectively.
Customers are also encouraged to regularly check their token balance, purchase history and deductions using mobile apps or USSD services to better understand their electricity spending patterns.
