Why Your Energy Bill Fluctuates
Weather plays a major role in energy use. As the weather gets hotter or colder, your home energy systems work harder to maintain your thermostat setting. Seasonal changes can result in higher energy usage.
Your billing period can vary from 28 to 34 days, depending on when your meter is read. Consider this when comparing monthly bills because the number of days in the billing period impact the amount of energy used.
Customers receive estimated bills because their meter could not be read for a variety of reasons. If a meter is estimated, it will be indicated in the Usage Profile box at the top right of your bill.
Your energy costs could fluctuate from conditions in your home such as door traffic, use of curtains and even appliance usage.
Adding or changing appliances will impact your bill. For example, buying a new refrigerator while keeping the old one running in the basement or installing a larger capacity washing machine will increase usage. Even temporary use of appliances can add up.
