Why Electricity Prices Differ So Much by State

Electricity prices differ by state mainly because of four things: the fuels and power plants each region relies on, the cost of building and maintaining transmission and distribution lines, how each state regulates its utilities, and climate, which shapes when and how much power people use. In 2025, average prices ranged from 35.72 cents per kWh in Hawaii to 8.20 cents in North Dakota, according to the U.S. Energy Information Administration.

Below we unpack each factor using EIA data, and explain why the price per kWh and the size of your bill are not the same thing.

How big are the differences?

The EIA reports that the average residential electricity price in 2025 was 17.30 cents per kWh, while the all-sector average was about 13.63 cents. Across states, prices ranged from 35.72 cents per kWh in Hawaii to 8.20 cents in North Dakota. That means some households pay several times as much per kWh as others for the same electricity. You can compare the latest figures on our electricity rates by state page, where the current national residential average is 18.16¢ per kWh.

What goes into the price of electricity

The EIA explains that electricity prices reflect the cost to build, finance, maintain and operate power plants and the grid, and that some for-profit utilities also earn a financial return for owners and shareholders. Generation is the largest component. Those costs fall into three broad buckets:

1. Generation: building and running power plants and buying fuel.
2. Transmission: high-voltage lines that move power from plants to local areas.
3. Distribution: local poles, wires and transformers that deliver power to homes.

Each of these varies by region, which is why prices vary too.

1. Fuel mix and power plants

Where a state's electricity comes from has a big effect on its price. Nationally, the EIA reports that in 2025 about 41% of utility-scale generation came from natural gas, about 18% from nuclear, about 17% from coal and about 24% from renewables, including wind (about 11%), solar (about 7%) and hydropower (about 6%). Petroleum was under 1%. Individual states can look very different from this national mix.

Factor	How it can affect prices	Example from EIA
Imported fuel	Fuels that must be shipped in are costly.	Hawaii's prices are high mainly because most of its electricity comes from imported petroleum.
Fuel price swings	Natural gas and petroleum prices can rise with high demand or supply disruptions.	Delivered coal and natural gas costs fell in 2024, helping Rocky Mountain states.
Water and wind conditions	Droughts reduce hydropower and low wind reduces wind output, so costlier sources fill the gap.	EIA lists weather as a key factor in electricity prices.
Power plant costs	Each plant carries financing, construction, maintenance and operating costs.	These costs are recovered through rates.

Hawaii is the clearest example. The EIA's Hawaii electricity profile lists petroleum as the state's primary energy source for electricity and shows Hawaii ranked first among states for average retail price in 2024. The EIA notes that petroleum matters for electricity prices mainly in Hawaii and some Alaskan villages.

At the other end, EIA's 2024 state bill analysis found that Rocky Mountain states, which rely heavily on coal and natural gas, saw the delivered costs of those fuels fall in 2024 and tend to have lower prices and consumption.

2. Transmission and distribution costs

Getting power from plants to homes is expensive. The EIA says transmission and distribution costs include building, operating and maintaining the system, repairing damage from storms or accidents and improving cybersecurity. These costs differ from one utility's service area to another and are reflected in the delivery part of customers' bills.

Delivery costs also explain why households pay more per kWh than factories. The EIA notes that residential and commercial customers pay the highest prices because distributing power to them costs more. Industrial customers take power at higher voltages, which is more efficient to supply, so their prices run closer to wholesale prices. In 2025, the EIA reports average prices of 17.30 cents per kWh for residential customers and 8.62 cents for industrial customers.

3. Regulation and market structure

States regulate electricity in different ways. The EIA explains that some states have public service commissions that fully regulate prices, while others have unregulated prices for generation and regulated prices for transmission and distribution. In some of these states, customers can buy supply from competitive suppliers while the local utility still delivers the power.

The District of Columbia shows how this splits a bill. The DC Public Service Commission says it regulates about 27% of a standard Pepco bill, mainly delivery, while about 73% is driven by regional supply prices and legislative mandates. State policies such as surcharges for low-income assistance, energy efficiency and renewable programs also appear on bills and differ from place to place.

4. Climate and seasonal demand

Weather affects both prices and how much electricity people use. The EIA says extreme temperatures raise demand for heating and cooling, and prices are usually highest in summer, when more expensive generation sources are added to meet demand. Demand also peaks in the afternoon and early evening, which is why some utilities offer time-of-use rates.

Climate also drives how much power homes use, and that matters for bills. EIA's 2024 analysis found that Louisiana households used more than twice as much electricity as those in Hawaii or California, reflecting heavy summer air conditioning and electric rather than gas heating. Low prices offset that usage, and the average Louisiana bill of $142 a month was close to the national average.

Price per kWh vs. your monthly bill

A high price per kWh does not always mean the highest bill, and a low price does not guarantee a small one. EIA's 2024 figures show the average US residential bill was $144 a month at 16.5 cents per kWh. Hawaii had the highest average bill at $213, even though its households used the least grid electricity on average, while Utah had the lowest at $89. Your bill depends on both the rate and how many kWh you use, which in turn depends on climate, home size, heating fuel and appliances.

The average US home now pays about $209 a month. Compare states on our average electric bill by state page.

What you can do about high electricity prices

• Know your rate. Divide your bill's total by kWh used to find what you really pay, and compare it on our state rates hub.
• Check your options. In states with retail choice, you may be able to compare supplier offers. Ask your utility about time-of-use or other rate plans.
• Cut usage where it counts. Focus on your biggest loads first. Check what your largest appliances cost to run at your local rate.
• Consider solar where it pays. Higher electricity prices generally improve solar payback; compare solar payback estimates for your state before deciding.
