Why Does My Bill Change?

Have you wondered why your electric bill may vary month-to-month, even when you feel your usage habits haven’t changed? You’re not alone! The energy you use, and thus your bill, is influenced by many factors.

Weather

Heating and cooling account for the majority of the average home’s energy use. Most homeowners keep their thermostat set to a specific temperature, sometimes varying it by season. However, this does not mean it’s always using the same amount of power. When outside temperatures hit extremes, your heating and cooling systems will need to work harder to maintain that selected temperature. The larger the difference from outside’s temperature, the more energy will be needed.

Rates

Your monthly bill is created using kWh usage recorded by your meter in conjunction with our kWh rate, which for residential members is currently $0.15 per kWh. After a rate adjustment goes into effect, a slightly higher kWh rate means that your routine usage will cost a little more. Our current rate was implemented at the end of 2025 to help cover the rising costs of providing reliable electric service. We always provide notice of planned rate adjustments in advance, so our members understand the reasons behind the change.

Longer Billing Cycles

Our billing system will show your usage for a specific period of time. That period of time may be a few days longer or shorter, depending on the number of days in the month, affecting how much kWh usage is factored in.

Lifestyle Changes

Even if you think your energy habits are mostly consistent, consider things you may have done differently during a billing period. If you had guests visiting, had seasonal decorations up, or even cooked at home more than usual, those activities will be reflected on your energy bill.

Aging Appliances

Appliances can become less efficient over time and use more energy to accomplish the same task. Make note of the age of your appliances and consider when may be the best time to replace them with more efficient models. When it’s time to upgrade, you should know that ENERGY STAR-certified clothes washers, clothes, dryers, and refrigerators qualify for a $50 rebate through your Co-op!
