Utility Costs by State: Electricity, Gas, and Water

The typical American household pays about $610 per month for essential utilities in 2026, and the state you live in matters more than almost any other factor. Hawaii's residential electricity rate sits at 39.89 cents per kilowatt-hour while Louisiana's is 12.44 cents per kilowatt-hour, a gap that adds up to thousands of dollars per year.

Electricity Rates by State in 2026

The national average residential electricity rate is 18.05 cents per kilowatt-hour as of May 2026, up from 17.45 cents in January 2026. Commercial customers pay less, averaging 14.12 cents per kilowatt-hour nationally, a gap of roughly 28 percent compared to residential rates.

The cheapest states for residential electricity are concentrated in the South and Mountain West. Louisiana leads at 12.44 cents per kilowatt-hour, followed closely by Oklahoma, Arkansas, and Idaho. These states benefit from abundant natural gas, hydroelectric power, or both.

The most expensive states cluster in New England and Hawaii. Hawaii is the extreme outlier at 39.89 cents per kilowatt-hour, driven by the cost of importing fuel to an island grid. Connecticut, Massachusetts, and Rhode Island all exceed 28 cents per kilowatt-hour, largely due to grid infrastructure costs and limited access to cheap generation sources.

Texas sits near the national average despite its energy-producing reputation. Deregulated electricity markets mean Texans can shop for rates, but average residential costs still land around 15 to 16 cents per kilowatt-hour depending on the plan and provider. California residential customers pay around 30 cents per kilowatt-hour, one of the highest rates in the continental United States.

Natural Gas and Heating Costs

Natural gas pricing follows a different pattern than electricity. The coldest states spend the most on gas, but production access matters too. States like Oklahoma, Kansas, and Texas pay some of the lowest natural gas bills because they sit on top of major production regions. New England states pay significantly more because they rely on pipelines that are often constrained during peak winter demand.

The expected utility increase for 2026 is running about 4 to 6 percent above 2025 levels for natural gas, driven by tighter LNG export demand and infrastructure constraints in transmission-heavy regions. Households heating with gas in the Northeast are absorbing the largest dollar increases.

Heating fuel, including heating oil and propane, remains a significant cost for rural households in the Northeast and Upper Midwest. Maine, Vermont, and New Hampshire have some of the highest total winter heating bills in the country because a large share of older homes still run on oil heat.

Water and Sewer: The Overlooked Cost

Water bills rarely get the attention electricity does, but they vary sharply by state and municipality. The national average monthly water and sewer bill runs around $75 to $95 for a typical household as of late 2025 data, the most recent available. Western states dealing with drought infrastructure costs and aging pipe replacement projects are seeing faster rate increases than most.

Phoenix, Las Vegas, and other desert metro areas have raised water rates steadily over the past several years to fund conservation and supply infrastructure. Meanwhile, cities in the Great Lakes region, sitting on abundant freshwater, tend to have lower rates, though aging infrastructure in cities like Detroit and Cleveland adds cost and risk.

States with older municipal infrastructure are facing significant capital investment cycles. Those costs flow directly to ratepayers through utility surcharges and rate increases that often outpace inflation.

What Total Utility Costs Look Like by Region

Putting electricity, gas, and water together, the most expensive states for total utility costs are Hawaii, Connecticut, Massachusetts, New York, and California. The least expensive states for combined utility costs are Louisiana, Arkansas, Oklahoma, Tennessee, and Idaho.

This matters significantly for retirees on fixed incomes, who often underestimate utility costs when planning a relocation. If you are already thinking about tax-friendly states for retirement, utility costs deserve equal weight in the analysis. Our post on The True Cost of Living in High-Tax States breaks down how these recurring costs stack against tax burdens, and our Best States for Retirees to Avoid Taxes guide pairs utility cost data with income and property tax comparisons.
