The hidden costs behind your higher electric bill

Your electric bill may be paying for more than the power you used, including fuel costs, storm repairs and upgrades to the grid.

Electric bills are climbing across much of the United States, and a record-hot summer is only part of the reason.

The average U.S. residential electricity price was 18.31 cents per kilowatt-hour in July, up from 17.45 cents a year earlier, according to the U.S. Energy Information Administration. Hawaii paid the highest residential rate, at 48 cents per kWh, while Louisiana paid the lowest, at 12.72 cents — nearly a fourfold difference.

What is causing increasing electric bill costs?

A Grist analysis found that California customers are paying in part for wildfire prevention and grid upgrades; the Southeast and mid-Atlantic are carrying costs from hurricanes and other extreme weather; and the Northeast remains vulnerable to swings in natural gas prices.

Electric bills can be complicated things, and the fine print does not always make the reason for a higher total obvious. But the bill can tell you whether the increase came from using more electricity, paying more for it or both. Start with the total kilowatt-hours used, then compare the supply rate, delivery charges and any riders or adjustments with the same month last year.

Electric bill 101: Start with the kilowatt-hours

A kilowatt-hour, usually written as kWh, is the basic unit of electricity on your bill. It measures how much power your household used during the billing period. If your kWh total is higher than it was during the same month last year, you used more electricity.

A sharp increase in kWh often points to weather. Long hot stretches make air conditioners run more often, but hot nights can be particularly expensive. When a home does not get a chance to shed the day’s heat, its cooling system keeps working after sunset.

Summer nighttime temperatures have warmed in 231 of the 241 U.S. locations analyzed since 1970, by 3.1 degrees on average, according to Climate Central. The Southwest saw the largest increase, with summer nights warming by an average of 4.5 degrees, although the top five cities with the largest increases in climate change-fueled warm summer nights are all in Florida.

On average, these cities currently experience about 27 warmer-than-normal summer nights with a strong climate change fingerprint each year, compared to one such day annually during the 1970s.

Urban heat can make that demand worse. Pavement and buildings absorb heat during the day and release it slowly after sunset, leaving cities warmer than nearby rural areas overnight. “So yes, cities are effectively adding their own layer of heat,” AccuWeather Meteorologist Brett Anderson said.

Hot summer nights limit our ability to cool off and recover from extremely hot summer days. This can lead to greater heat stress and related health risks.

But if your household used about the same number of kWh as last year and the bill still jumped, the answer is probably not your thermostat. It is time to look at the other charges.

What else is on your bill?

Most electric bills include a charge for the electricity itself, another for getting it to your home and a handful of additional fees. The labels vary by utility, but the biggest ones are usually supply or generation, delivery, customer charges and riders or adjustments.

Supply or generation is the cost of making or buying the electricity that enters the grid. Utilities may generate it themselves or buy it from power plants and wholesale markets. That cost can rise when fuel prices rise, especially natural gas, which remains a major source of U.S. electricity.

That helps explain why winter weather can affect electricity costs in the Northeast. Homes and businesses use more natural gas for heat during a cold snap while gas-fired power plants need it to produce electricity. When there is not enough gas moving through the pipelines to meet both needs cheaply, power plants pay more, and customers can see the increase in the supply part of the bill.

Delivery, sometimes called distribution or transmission, pays for the physical system that moves power to a home: long-distance lines, local wires, poles, substations, transformers, maintenance crews and repairs.

The delivery charge can also include the cost of keeping the grid from failing. Utilities can pass along regulator-approved spending to replace old poles and wires, repair storm damage, trim trees away from power lines, reduce wildfire risk and build new substations or transmission lines.

Those costs can outlast the event that created them. Florida customers saw residential price increases after damage from Hurricanes Debby, Helene and Milton in 2024, Grist reported. Texas has also poured money into its grid since the 2021 winter storm exposed major weaknesses in the state’s isolated system.

Unlike most of the country, Texas operates largely on its own power grid. Most of the state is served by the Electric Reliability Council of Texas, or ERCOT. Because the Lone Star State isn’t fully connected to the major U.S. power interconnections, it cannot easily pull electricity from other states when demand spikes or equipment fails.

Customer charges are usually fixed monthly fees for maintaining an active account and connection to the grid. You pay them even in a month when you use very little electricity.

Riders, adjustments and surcharges are the smaller line items that can be hardest to figure out. A fuel rider, for example, can pass along what a utility paid power producers or wholesale markets for the natural gas, coal, oil or other fuel used to generate electricity. Other riders may cover storm restoration, energy-efficiency programs, renewable-energy projects or a specific grid upgrade.

The exact names differ, but the comparison is simple: Pull up the same bill from last year. Did the supply rate rise? Did delivery charges increase? Is there a new rider?

If your kWh use is high, look inside the house

A higher bill can also be an inside-the-house problem. Heating and cooling account for about half of home energy use. Electric water heaters, clothes dryers and older refrigerators can also add to monthly use. A refrigerator runs around the clock; a water heater works harder as household demand rises; and a dryer draws a lot of electricity in a short time.

Drafty doors and windows, poor insulation and aging heating-and-cooling equipment can make those costs worse by forcing a system to run longer. Electronics that appear to be off can still draw standby power, which is the electricity consumed by devices when they are switched off or not performing their primary functions.  Lawrence Berkeley National Laboratory estimates that standby power accounts for 5% to 10% of household electricity use.

If your kWh use rose during mild weather, check whether the bill was based on an actual meter reading or an estimate. Your utility’s online portal or smart-meter data may reveal unusually heavy overnight use, a new appliance drawing more power than expected or a heating-and-cooling system running when it should not be.

The grid is changing, but not overnight

More renewable power is coming online, though that does not mean the next bill will automatically fall. Solar produced more U.S. electricity than coal for the first time on record in May, according to an Ember analysis reported by Grist. In Utah, solar became the state’s largest electricity source for the first time that same month.

Unlike a natural-gas or coal plant, solar panels and wind turbines do not need to buy fuel once they are running, every time they generate electricity. That can reduce exposure to sudden swings in fossil-fuel prices, but building solar farms, wind projects, batteries and the power lines that connect them requires major upfront investment.

Utilities often recover those costs through customer bills over time. Whether the change ultimately lowers bills depends on how much the projects cost, what fuel expenses they replace and how regulators spread the costs among customers.

For now, the clearest way to read a high bill is to separate use from price. If your kWh total climbed, weather or an appliance may be the culprit. If the supply rate, delivery charges or riders went up, the bill is reflecting the cost of electricity, and the system that keeps it moving.
