Compare Major US Utility Electricity Rates (2026)

The table below provides a quick comparison of average residential electricity prices across major utilities. Values are representative estimates and should be refreshed whenever individual utility rate pages are updated.

Actual monthly bills vary depending on taxes, fuel adjustments, demand charges, delivery fees, and rider programs.

How These Calculators Work

Every utility has its own billing structure, which is why using a dedicated calculator provides more accurate estimates than multiplying your energy usage by a single electricity rate.

Most calculators require only a few inputs:

• Monthly electricity consumption (kWh)
• Utility provider
• State or ZIP code
• Rate plan, if available
• Optional seasonal or time-of-use selection

After entering these values, the calculator estimates your energy charge using the latest available residential pricing. Some utilities apply tiered pricing where electricity becomes more expensive after certain usage levels. Others use time-of-use plans that charge different prices during peak and off-peak hours.

Many utilities also include delivery charges, customer service fees, renewable energy riders, fuel cost adjustments, and local taxes. Dedicated utility calculators account for these billing components whenever practical, giving users a closer estimate of their actual electricity bill.

Why Electricity Rates Differ Across Utilities

Electricity prices are not the same across the United States because every utility operates under different market conditions, regulatory policies, infrastructure requirements, and energy generation sources. These factors directly affect the price customers pay for each kilowatt-hour of electricity.

State Regulations and Public Utility Commissions

Every state has its own Public Utility Commission (PUC) or regulatory authority that reviews and approves electricity rates. These agencies evaluate utility investments, operating costs, and infrastructure projects before allowing changes to customer tariffs. As a result, neighboring states may have significantly different residential electricity rates.

Energy Generation Mix

The source of electricity plays a major role in determining customer bills. Utilities that rely on natural gas, coal, hydroelectric power, nuclear energy, solar, or wind have different operating costs. Fuel price fluctuations and renewable energy investments can also influence the final electricity rate.

Transmission and Distribution Costs

Electricity must travel from power plants to homes and businesses through transmission and distribution networks. Utilities serving large rural areas usually maintain longer power lines, while urban utilities invest heavily in underground cables and grid modernization. These infrastructure costs are reflected in electricity bills.

Time-of-Use and Tiered Pricing Plans

Many utilities no longer charge a single flat electricity rate. Instead, customers may be billed using Time-of-Use (TOU) pricing or tiered rate structures.

• Time-of-Use plans charge different prices during peak and off-peak hours.
• Tiered pricing increases the cost per kWh after certain usage thresholds.
• Some utilities combine both pricing methods for residential customers.

Weather and Seasonal Demand

Extreme weather affects electricity demand throughout the year. Air conditioning during summer and electric heating during winter increase energy consumption, leading to higher demand on the electrical grid. Some utilities introduce seasonal rates or fuel adjustments to recover these additional operating costs.

Deregulated vs. Regulated Electricity Markets

Not every state follows the same electricity market structure. In regulated markets, customers purchase electricity directly from the local utility. In deregulated markets, customers may choose an electricity supplier while the local utility continues to maintain the distribution system.

Utility Infrastructure Investments

Utilities regularly invest in new substations, transmission lines, smart meters, cybersecurity, renewable energy integration, and wildfire prevention programs. These long-term capital projects improve grid reliability but may increase electricity rates after regulatory approval.

Local Taxes and Additional Charges

Your monthly electricity bill usually includes more than just the energy charge. Depending on the utility and state, additional costs may include:

• Customer service charges
• Distribution charges
• Transmission fees
• Fuel adjustment clauses
• Renewable energy riders
• Local and state taxes

These charges vary by utility and explain why two households using the same amount of electricity can receive different monthly bills.

How to Compare Electricity Costs Accurately

When comparing electricity costs, always use the calculator designed for your local utility instead of relying on national averages. Utility-specific calculators include the latest residential rate information and provide estimates that are much closer to actual bills. For the most accurate results, compare your monthly usage with the dedicated calculators for providers such as ComEd, PG&E, Con Edison, FPL, Duke Energy, or your local electricity company. This approach gives a realistic estimate based on current utility pricing and billing practices.
