Yes, low voltage can increase your electricity bill, but not directly. You know electricity meters measure energy in units (kWh). When the voltage decreases, many appliances compensate by drawing more current or running for longer periods to do the same task. It finally leads to higher overall electricity consumption.
How does Low Voltage Increase Electricity Bill?
You know the following formula:
Power (Watts) = Voltage (Volts) x Current (Amps).
To keep the same power output (Watts), the current must rise as the voltage decreases.

Under low voltage, appliances such as washing machines, air conditioners, refrigerators, and water pumps may operate longer and eventually consume more units.
To maintain power output, some appliances require more current at lower voltages. In addition to increasing energy consumption, this additional current may result in heat losses.
Low voltage causes motors to become inefficient, which ultimately results in high unit consumption. Additionally, it lowers appliance efficiency, which eventually raises power costs.
When stabilisers are used during frequent voltage changes, there is a modest increase in power consumption.
Let’s understand this with an example. A refrigerator with a 300W rating at 250V uses 1.2 amps (300/250). More energy is wasted if the voltage lowers to 180V since it requires 1.6 Amps (300/180) to provide the same power.
How to Reduce the Impact of Low Voltage?
For delicate appliances, you must use voltage stabilisers.
Steer clear of using heavy-load appliances during low-voltage peak hours.
Reach out to your electrical provider if the voltage is consistently low.
Ultimately, low voltage does not directly affect electricity bills, but it might indirectly raise usage by lowering appliance efficiency. Hope you found this helpful.
