A multiplier (sometimes referred to as a k-factor) on your invoice indicates that you are a high usage tenant and that your actual consumption is too high for your meter to record. Multipliers help to prevent the meter from rolling over too often.
Commercial tenancies that are likely to require a lot of electricity are typically set up with multipliers of 40, 160, or 300.
For instance, if your multiplier is 40, the meter will record 1/40th of the actual usage between the start and end read dates. To determine the actual usage, we must multiply this by 40.
