Why Is My Electric Bill So High?

Data through May 2026 (the latest month EIA has published) · Updated August 14, 2026

As of May 2026, the average U.S. residential electricity rate is 18.44¢/kWh, up +6.2% in one year and +40.8% since May 2020, per EIA data. The average monthly bill is $135.70. A high bill has three immediate causes: you used more electricity, your rate went up, or the structure of your bill changed. Behind the rate increases sits a structural shift: U.S. electricity demand is growing again, led by data centers, while spending on the grid itself keeps climbing.

First, diagnose your own bill: the three drivers

Before the big picture, check which of these applies to you. Compare this month's bill to the same month last year, not to last month.

1. You used more electricity. Usage is strongly seasonal. In 2025, the average U.S. home used as little as 678 kWh in April and as much as 1166 kWh in July, per EIA data. That swing alone can move a bill by $90 at the current average rate. Your bill prints the kWh you used; compare it to the same month a year ago before blaming the rate.
2. Your rate went up. The U.S. average residential rate rose +6.2% over the past year, and some states rose far more. Look up your state's trend on our rates-by-state hub; every state page charts the last three years against the national average.
3. The bill itself changed. A higher fixed monthly charge, a new rider approved in a rate case, an expired fixed-rate supply contract (in states with retail choice), or a switch to time-of-use billing can all raise a bill even when usage and the headline rate are flat. Compare the fixed charges and the per-kWh line items against an old bill.

The U.S. rate trend since 2020

Why rates keep rising: demand is back, led by data centers

For roughly 15 years, U.S. electricity demand was close to flat, and utilities competed to serve the same load. That era is over, and the clearest driver is data centers.

• Data centers used 176 TWh of electricity in 2023, 4.4% of all U.S. consumption, up from 58 TWh in 2014, according to the 2024 U.S. Data Center Energy Usage Report Lawrence Berkeley National Laboratory prepared for the Department of Energy. The same report projects 325 to 580 TWh by 2028, or 6.7% to 12% of U.S. electricity.
• Scarcity is now priced into wholesale markets. In PJM, the grid operator for 67 million people across 13 states and DC, the price generators are paid just to be available (the "capacity" price) cleared at $28.92/MW-day for 2024/25, $269.92 for 2025/26, $329.17 for 2026/27, and $333.44 for 2027/28, the last two at a FERC-approved price cap, per PJM's December 2025 auction results and IEEFA's summary of prior auctions. That December 2025 auction was the first in PJM history to fall short of the region's reliability requirement, by 6,623 MW.
• PJM attributes the demand growth directly to data centers. Forecast peak load rose about 5,250 MW between the last two auctions, and PJM states that "nearly 5,100 MW of that increase is attributable to data center demand." In PJM's own words: "this auction leaves no doubt that data centers' demand for electricity continues to far outstrip new supply."
• Those costs reach household bills. Monitoring Analytics, PJM's independent market monitor, estimated that data centers were responsible for 63% of the 2025/26 capacity-price increase, roughly $9.3 billion in one delivery year recovered from customers across PJM in rates. Under today's rate designs, capacity costs and grid upgrades are recovered from all customers on the system.
• Grid spending is rising at the same time. EIA reported in May 2025 that retail electricity prices have risen faster than inflation since 2022 as utilities increased capital investment to replace and upgrade aging generation and delivery infrastructure, with spending on distribution now exceeding spending on transmission or generation.

Where rates are rising fastest

From our EIA-derived state tracker: the eight states with the largest residential rate increases over the past five years (May 2021 to May 2026).

5 of the eight are served wholly or partly by PJM, the grid region where data-center demand growth has been most concentrated. Rate changes also reflect state-specific factors (fuel mix, policy, storm hardening, infrastructure programs), so territory overlap by itself does not establish cause; it is consistent with the capacity-cost story above.

What you can actually do

• Find the driver first. Same-month kWh comparison for usage; your state page for the rate trend; the bill's fixed charges and line items for structural changes.
• If usage is the driver, the seasonal swing (678 to 1166 kWh for the average home in 2025) points at heating and cooling months; that is where the month-to-month dollars are.
• If you live in a retail-choice state, check the supply rate you are actually paying against your utility's current default offer; expired promotional contracts commonly reset to much higher rates.
• Run the numbers with the bill estimator at your state's current average rate.

Frequently asked questions

How much of U.S. electricity do data centers use?

About 4.4% in 2023 (176 TWh), per the LBNL report prepared for the U.S. Department of Energy. LBNL projects that share reaches 6.7% to 12% by 2028.

Do data centers raise residential electric bills?

In the PJM region, the independent market monitor estimated data centers were responsible for 63% of the 2025/26 capacity-price increase, roughly $9.3 billion recovered from customers in rates. The effect varies by region; areas with little data-center growth see less of it.

Why did my bill go up if my usage didn't?

Then the rate or the bill structure changed: a higher per-kWh rate, a higher fixed charge, a new rider, an expired supply contract, or a time-of-use plan. Compare the per-kWh price and fixed charges on this bill to the same month last year.

Will electricity prices go down in 2026?

We track published data rather than forecast. As of May 2026, the U.S. average rate was up +6.2% year over year, and EIA's May 2025 analysis expected retail prices to keep rising through 2026.
