November started out with some record cold weather, and when the temperature drops, energy usage and bills will go up. Changing how you use energy can help you control the price you pay during the winter. Here’s what you need to know about how what’s happening outside your window affects what goes on inside.


A big influence on the amount of energy you use to heat your home is the weather outside. When temperatures fall, your furnace runs more often and for longer, increasing the amount of energy you use.

You can help reduce the weather’s impact on your bill by sealing air leaks that allow frigid air into your home and let the warm air out. Use caulk or weather stripping to seal leaks around windows and doors and consider installing more energy-efficient windows and doors when remodeling.

Increased usage

An increase in usage will cause your bill to rise as well. When assessing why your usage has increased, here are some things to consider:

  • Did you raise your thermostat setting?
  • Were you or your family home more often? Snow days and working from home will change your usage.
  • Are there more people in your home? Did family come to visit for the holidays?

To keep a handle on your usage, install and set a programmable thermostat to automatically increase the temperature when you’re awake and reduce the temperature when everyone is asleep or while you’re away from home. To stay comfortable around the house, put on an extra layer of clothing or use a blanket to stay warm. With proper use throughout the year, programmable thermostats can save you about $180 annually in energy costs.

Longer bill cycles

Your bill covers a month’s worth of energy usage, but because of several factors, the exact number of days on your bill can vary from month to month. As a result, you may sometimes receive a bill that covers as few as 28 or as many as 35 days of service. This can make your total bill larger even if your usage patterns didn’t change.

Estimated meter readings

Sometimes, especially in ice and snow, it can be difficult or impossible for us to get an actual meter reading of your usage. When that happens, we will estimate your meter reading, which can over- or underestimate your actual usage and can result in a fluctuating bill.

To ensure that your bill reflects your actual usage and not an estimated reading, it’s important to keep your meter clear of ice and snow. It’s also crucial that there is a clear, safe path to and from your meter.
