US Electricity Rates Up 11.8% Since 2024 — State-by-State Breakdown

Yes — US electricity rates are going up, and faster than most homeowners realize. The national average residential price of electricity climbed from 16.6¢/kWh in 2024 to 18.56¢/kWh in March 2026, an 11.8% increase in roughly two years. For a household using 1,000 kWh a month, that is an extra ~$20 every month for the exact same energy — before this summer's air-conditioning season even starts. Every percentage point of rate inflation makes rooftop solar more valuable, because solar lets you lock in your cost of energy against a utility bill that keeps climbing.

The Data: What Happened to Electricity Rates

According to the U.S. Energy Information Administration's Electric Power Monthly (Table 5.6.A), the average residential retail price of electricity in the United States was about 16.6¢ per kilowatt-hour (kWh) in 2024. By March 2026, that same figure reached 18.56¢/kWh — a 11.8% increase in under 24 months. For context, the prior decade averaged roughly 3% annual rate growth. The last two years have run roughly double that pace.

Translated into a bill: a home consuming 1,000 kWh/month paid about $166 for energy in 2024 and about $186 at March 2026 prices — before fixed charges and fees. Add in the larger fixed fees many utilities have introduced, and the real increase households feel is even steeper.

Why Rates Keep Rising

Several structural forces are pushing prices up simultaneously, and none of them look likely to reverse soon:

• Grid & transmission investment. Utilities are spending tens of billions hardening poles, wires, and substations after a string of wildfire and winter-storm blackouts. Regulators let them recover those costs through rates.
• Fuel cost volatility. Natural gas still sets the marginal price of power in most of the country. Gas price spikes flow straight through to residential bills within a billing cycle or two.
• Data centers & AI demand. Explosive growth in computing load — concentrated in states like Virginia, Texas, and Arizona — is straining local grids and triggering expensive new generation and transmission builds that all ratepayers help fund.
• Extreme weather. Hotter summers (more AC run-time) and deeper winter freezes drive peak demand spikes. Meeting those peaks requires costly "peaker" plants and capacity payments.
• Electrification. As more homes adopt EVs, heat pumps, and induction cooking, total demand rises. Without matching supply and wiring upgrades, that pushes up the per-unit cost of delivering reliable power.

The net effect is a utility bill that ratchets up a little every six months — quietly, until you compare this year's statement to last year's.

What This Means for Homeowners

Rate increases compound. At the recent pace, a bill that is $150 today could be over $185 in three years even if your usage stays flat — and most households' usage is rising as they add EVs and electric heat. Unlike almost any other household expense, your electricity cost is something you can effectively freeze by generating your own power. Want to see exactly what your current bill breaks down into?

The Solar Offset: Locking In Your Energy Cost

The single biggest driver of solar payback is your electricity rate — bigger than panel price, bigger than sun hours. When the utility raises its rate, every kWh your panels produce offsets a more expensive kWh. A system that saves you $1,500/year at 16.6¢/kWh saves closer to $1,675/year at 18.56¢/kWh, with zero extra equipment. That is why rising rates shorten solar payback periods even as the federal residential tax credit has expired.

Think of rooftop solar (and especially solar plus a battery) as a 25-year hedge against utility inflation. You pay a known upfront cost and thereafter your marginal cost of energy is essentially fixed, while your neighbors absorb each new rate hike. The higher rates climb, the shorter that break-even becomes — and rates have been climbing fast.

State-by-State Impact

Rate increases are not evenly distributed. Hawaii residents face the highest March 2026 rate at 42.86¢/kWh, while North Dakota pays the least at 11.7¢/kWh. The steepest two-year jump belongs to Maine (+15.5%); the mildest is Washington (+8%). Use the table below to sort, search, and find your state — higher current rates and bigger increases both translate directly into stronger solar savings.

What Higher Rates Do to Solar Payback

Because solar savings scale 1:1 with your avoided retail rate, the same rooftop system becomes more valuable in every rate-hike cycle. A state stuck paying 42.86¢/kWh offsets nearly four times as much bill value per panel as one paying 11.7¢/kWh. And in states where rates jumped the most — like Maine at +15.5% — the payback math improves every single time the utility refiles its tariffs.

Methodology & Data Sources

National anchor figures are the U.S. Energy Information Administration Electric Power Monthly, Table 5.6.A (Average Retail Price of Electricity to Ultimate Customers): the 2024 annual residential average (16.6¢/kWh) compared with the March 2026 residential average (18.56¢/kWh), a 11.8% change. The state-level values in the table above are EnergyTools estimates: we started from reported state residential rate ratios and scaled them so the simple state mean reproduces the EIA national averages for each period, then computed each state's percentage change from its displayed rounded rates. Figures are rounded to two decimals (rates) and one decimal (percent). Treat the state numbers as indicative comparisons, not as an exact utility tariff — always verify your actual rate on your utility bill. NREL PVWatts is used elsewhere on this site for production estimates and is independent of this rate dataset.

The Bottom Line

Electricity rates are up 11.8% nationally since 2024 and the forces driving them — grid spending, data-center load, extreme weather — are not going away. Every increase makes the energy you generate yourself worth more. If you have not run the numbers on your roof lately, the math has changed in solar's favor. The fastest way to find out is to model it with your own rate and usage.
