You probably don’t spend a lot of time thinking about your energy use until you receive your monthly bill. Many factors can affect your bill. Check out the resources below to understand why your bill may have changed and how to avoid surprises in the future.​​
 
 

​​​​​​
seasonal rates
As the need for energy to run air conditioning units and other equipment in the summer increases, so does the cost to deliver it. All non-residential service plans have a higher $/kWh charge in the summer than they do in the winter. A change in your bill may not be that you used more energy but rather the new $/kWh has gone into effect.​
​You can determine if this is the case by logging into your account and comparing your usage this month to the same time last year or referencing the “Comparing your monthly use” section of your printed bill.​
 
You can find the seasonal $/kWh rates specific to your plan by viewing your service plan details.​

monthly factors
​Local weather and the number of days included in your bill changes every month which has a direct impact on your total energy use.
Number of billing days – The number of days included in your bill can change each month. If last month only had 29 days and this month included 31, you may see a higher bill.
 
Weather – When there is a heat wave or cold spell, your cooling or heating system has to run more to maintain the desired temperature which results in more energy use.
 
You can quickly determine the impact of these on your bill by logging into your account or referencing the “Comparing your monthly use” section of your printed bill.

other reasons bills change
While you are busy running your business, you may not realize the impact that operational changes can have on your energy use. Consider the following:​
  • Did you recently install new equipment? New equipment may use more energy, and depending on when it turns on, can also impact your demand.
  • Was it specifically your demand charge that went up? Check your bill to see if the billed demand increased. If it has, and you did not install any new equipment, conduct a walk-through of your facility. Someone may have changed when certain pieces of equipment are turning on which has created an unnecessary spike in demand.
  • Was there a change to your operating hours? Perhaps you had a deadline to meet and worked extra hours or hosted an after-hours event. Those hours can equate to additional energy use.
  • Did the building occupancy increase? If you hired additional employees or a space that was previously vacant is now occupied, you will see an increase in energy use. People naturally emit heat which makes air conditioning units work harder and most likely require you to power an additional computer or other equipment to support their work function.
  • Are your thermostat set points appropriate? When it’s 110 degrees outside in the summer, 78 degrees seems cool but when winter sets in, 76 might feel warm enough and you can take some pressure off your system. Also make sure that your thermostat settings reflect your facility’s occupancy and you aren’t unnecessarily cooling or heating the space when no one is there to benefit from it.
  • Was there any maintenance or construction? If you expanded, that is additional space that needs to be cooled or heated, extra lights to power and more. Additionally, if you had any maintenance work done, those crews were probably coming and going, propping doors open and plugging in their tools. All of these things can add up to additional energy use. ​
