EXPLAINER: Why Power Bills Don’t Change Even After Cutting Off Heavy Appliances
Chances are that you have at one point noticed your electricity tokens running out faster than expected, even after deliberately cutting down on appliance use at home.
For many, this often raises suspicion about possible overbilling or system errors by Kenya Power.
But that is not always the case. In some instances, the explanation lies much closer to home, literally inside your sockets.
Even when switched off, certain electrical appliances can continue consuming power as long as they remain plugged in.
This phenomenon is commonly referred to as phantom loading, also known as ‘vampire power’, and it is one of the hidden contributors to rising electricity bills in many households.
Phantom loading describes a situation where electronic devices continue to draw small amounts of electricity even when they are not actively in use.
This typically happens in appliances that have standby modes, internal clocks, remote control sensors, or indicator lights.
Common culprits include televisions, decoders, microwaves, phone chargers, and desktop computers.
While each device may consume only a small amount of power, the cumulative effect across multiple appliances over time can be significant.
In simple terms, as long as an appliance is plugged into a power source, there is a continuous flow of electricity, even if the device appears to be off.
This silent consumption is what gradually reflects on your meter readings and ultimately your bill.
According to Kenya Power CEO Joseph Siror, electricity costs in Kenya are influenced by several factors beyond just visible usage.
He explains that consumer perception of high bills often depends on usage patterns and the type of appliances in a household.
Households that consume minimal electricity typically fall under the lifeline tariff, which offers subsidised rates.
However, once consumption exceeds 100 kilowatt-hours (kWh), users are automatically moved to higher tariff bands, where each unit costs more.
This means that even small, unnoticed consumption, such as phantom loading, can push a household into a more expensive billing category over time, especially when combined with other energy-intensive appliances.
“The perception that electricity is expensive is subjective. If you turn on five or ten bulbs that are 5 watts each, that is about 50 watts,” Siror said in a past interview.

“If you ran them for 20 hours, you would still be within the lifeline category. That would just be about a single unit, which costs roughly Ksh12 and about Ksh16 with taxes.”
Beyond household usage, Siror notes that electricity pricing also reflects the cost of infrastructure.
Kenya has invested heavily in power generation, transmission lines, and distribution networks, all of which contribute to the final cost passed on to consumers.
To reduce unnecessary costs, experts recommend unplugging devices when not in use.
Additionally, one can use power strips to easily switch off multiple appliances, and opting for energy-efficient electronics designed to minimise standby power consumption.
