Why Is My Electric Bill So High This Month?
Concerned about your high electric bill? Learn how to systematically investigate and pinpoint the reasons for increased energy costs.
An unexpectedly high electric bill can be frustrating. Many factors, both within and outside your control, can contribute to increased electricity costs. Understanding these potential causes is the first step toward identifying the reasons behind your higher energy expenses.
Understanding Your Energy Consumption Patterns
Changes in daily routines and appliance use directly influence electricity consumption. Heating and cooling systems are the largest energy consumers. Increased reliance on them due to extreme seasonal temperatures drives up energy use. Adjusting thermostat settings to cooler temperatures in summer or warmer temperatures in winter increases HVAC workload and bills.
Increased occupancy or more time spent at home leads to greater electricity usage. When more people are present for longer periods, such as due to remote work, holidays, or extended guest stays, lights, electronics, and cooking appliances are used more frequently. This translates into higher electricity demand.
Adding new, high-wattage devices or increasing use of existing large appliances can boost consumption. For instance, installing a second refrigerator, frequently using gaming consoles, or charging an electric vehicle adds to the energy load. Even simple lifestyle shifts, like cooking more often or increasing screen time, contribute to higher electricity costs. Reflecting on recent changes in household routines and appliance usage can reveal consumption drivers.
Impact of External Factors and Utility Changes
Factors beyond direct household consumption can also cause an electric bill to rise. Sustained periods of unusually hot or cold weather force heating and cooling systems to operate more intensely and for longer durations. This increased operational time translates into higher electricity usage.
The per-kilowatt-hour (kWh) cost of electricity may have increased due to utility rate adjustments. Utility companies modify rates to account for fluctuating fuel costs, investments in infrastructure, or regulatory changes. These adjustments are typically reviewed and approved by state public utility commissions. Consumers should check their utility’s official communications for notices regarding such rate increases.
Some billing plans incorporate Time-of-Use (TOU) rates, which charge different prices for electricity based on the time of day. Under TOU plans, electricity is more expensive during “peak” hours when demand is high, such as late afternoons and evenings, and less expensive during “off-peak” hours. Shifting significant energy consumption to peak hours can increase the overall bill, even if total kWh usage remains consistent. Additionally, new fixed charges, delivery fees, or other surcharges might have been added, contributing to a higher total.
Identifying Inefficient Appliances and Home Issues
Electricity can be wasted within a home due to inefficient appliances or structural issues. Older appliances, particularly large ones like refrigerators, freezers, or water heaters, become less energy-efficient over time. A malfunctioning appliance, such as a refrigerator compressor that runs constantly, can consume more power than usual. Upgrading to ENERGY STAR-certified models can lead to substantial energy savings, with some older refrigerators consuming 35% more energy than newer models.
Many modern electronics and appliances continue to draw a small amount of power even when turned off or in standby mode, known as phantom load or vampire draw. Devices like televisions, device chargers, computers, and game consoles contribute to this continuous power drain. This standby power can account for a notable percentage of a household’s electricity usage, with some estimates suggesting it could be 5-10% of total consumption. Simple mitigation strategies include unplugging devices when not in use or employing smart power strips that cut power to idle electronics.
Poor home insulation and air leaks also force heating and cooling systems to work harder, leading to increased energy consumption. Drafts from poorly sealed windows and doors, gaps in the building envelope, or inadequate attic or wall insulation allow conditioned air to escape, making HVAC systems run longer to maintain desired temperatures. Proper insulation can reduce heating and cooling costs. Leaks in HVAC air ducts can cause conditioned air to escape, wasting energy.
Verifying Billing Accuracy and Meter Readings
Investigating potential errors in utility billing or issues with the electric meter is important when faced with a high bill. Begin by carefully comparing the current bill with previous months’ bills to identify any unusual spikes or inconsistencies. Look for indicators such as “estimated” versus “actual” meter readings, verify account information, and check for duplicate charges or incorrect meter numbers listed. Utility companies may estimate usage when actual readings are not obtained.
Understanding how to read your electric meter allows for verification of the utility’s reported consumption. For digital meters, the kilowatt-hour (kWh) reading is displayed on the screen. For analog meters with dials, readings are taken from left to right, noting the number the pointer has most recently passed. Comparing your physical meter reading to the one stated on your bill helps determine if the recorded usage is accurate.
If discrepancies are found or the cause of the high bill remains unclear after initial checks, contact the utility company. When reaching out, have information ready, such as your account number, specific bill details, and any personal meter readings you have taken. Common billing issues to inquire about include prolonged estimated bills, transposed numbers in meter readings, or misapplied payments. Investigating these potential errors empowers consumers to challenge incorrect charges.
