Seasonal Changes
Is there a seasonal aspect to your business, where for example you're using more air conditioning than usual or processes change by season?
More Occupants
Did your company change in size? More people means more equipment, computers and air conditioning.
Equipment Left Running That's Not Being Used
Do you have equipment that's in an "always on" mode, similar to televisions that start up the minute you turn them on? This type of equipment continues to use energy if it's switched off. Unplug it to save energy.
Additional Equipment
Did you purchase more equipment? More computers?
Aging or Faulty Equipment
A faulty thermostat, a motor that needs a tune-up, or refrigerator with a poor door seal can lead to a surprisingly high electricity bill.
Previous Estimated Bill
If your past bills have been estimated, your current bill may be adjusted to reflect the actual usage. Examine your previous bill to see if they say "estimated".
Variation in Billing Days
In a bi-monthly billing cycle, the number of days may typically range anywhere from 57 to 63. That's a possible difference of six days from one billing period to the next and the billing cycle may include eight weekends, a time of increased electrical use for some types of businesses.
