Home Our Services Electricity Tariffs


Measuring your consumption

Your electricity consumption is measured in kilo watt hours (kWh). One kilo watt hour is the amount of electrical energy consumed when switching on electrical equipment rated at 1,000 watts for one hour. In your bill, one kilo watt hour is represented as one unit.
Customers with high electricity consumption levels connected through dedicated electricity supply cables receive readings in kilo volt-ampere hours (kVAh). This unit represents an electrical power of 1,000 volt-amperes dissipated continuously for a period of one hour. 
Your electricity consumption is measured through the electricity meters installed in your property. We measure electricity consumption through smart meters that are capable of transmitting your electricity consumption data to us remotely. Smart meters also provide you with additional information, including daily consumption readings, at the press of a button, to help you monitor and control of your energy use. In some cases, ARMS might still need to send its meter reader to take note of your smart meter readings for billing purposes.
