Where you live affects your electricity rate

October 2018 data, the latest available, show that the average U.S. price – 12.87 cents per kilowatt hour (kWh) – rose 0.5% compared with a year ago. If you live in Louisiana, you paid the lowest average residential electricity rates of any state in the country – 9.11 cents per kWh. The next lowest rate is in Arkansas, where residents pay an average of 9.34 cents per kWh.

Below are the cheapest 10 states to live in based on residential electricity rates:

Rank State October 2018 Electric Rate
1 Louisiana 9.11

Looking deeper: Residential electric rates through the year

The average home in the U.S. consumes 897 kilowatt hours (kWh) of electricity per month. Bills vary by state and region, as cost per kWh differs. To estimate average monthly energy bills, multiply the average home’s electricity usage (897 kWh) by the cost per kWh in your state for that month. For example, the average cost per kWh in October for Iowa homes was 12.82 cents, which amounts to an average bill of about $115 (12.82 cents x 897 kWh) that month. Find your state on the interactive map below to see the latest average rate, its rank among other states and the percentage change from the previous month.

The Choose Energy Price Index

In 2018, we kicked off the Choose Energy Price Index, a proprietary tool that combines the average electricity rate by state with a state’s average monthly usage to produce a number that reflects average monthly bills for a state. The index is a ratio of that state’s average monthly bill compared with the average U.S. bill.

Other measures alone don’t accurately reflect monthly residential bills. Take the following case:

  • Residents of Virginia paid an average of 11.90 cents per kilowatt hour (kWh) for their electricity in October, the 20th-lowest rates in the country and well below the U.S. average of 12.87 cents/kWh. However, they use an average of 1,120 kWh per month, well above the U.S. average of 897. That leaves the state with a Choose Energy Price Index score of 115.2, which places it 42nd nationally.

In other words, prices and bills aren’t directly correlated. Choose Energy will track changes using the index on a monthly basis.

Commercial electricity rates through the year

In states with energy choice, the open market is not only for residents. Businesses also can take advantage of pricing and plans available through an energy supplier. In some states, only business customers have energy choice. Across the United States, the average business consumes 6,278 kWh of electricity per month and receives a bill of nearly $655.

Electric rates for companies vary greatly by industry and function. Although homes come in all shapes and sizes, businesses have larger variations with diverse needs – from industrial buildings to mom-and-pop businesses. In October, for example, the average business in Florida paid 12.40 cents per kWh. With this number, we can deduce that on average companies in the state paid about $585 that month for electricity.

See the Choose Energy Business Energy Index for a more in-depth look at commercial and industrial electricity rates.

Understand the energy market

Due to the volatility of the energy market, energy supply prices may fluctuate throughout the year. From October 2017 to October 2018, Hawaii experienced the biggest fluctuation in Residential Energy Rate electric prices, while New Mexico had the most consistent prices.

Fluctuations in electricity prices may seem random, but there are a few primary factors that determine how much you pay. These factors are:

  • What time you use energy: Some energy suppliers offer plans with time-of-use discounts, such as free energy supply from 9 p.m. to 6 a.m.
  • What month you use it: In warmer states, summer rates can be higher than winter rates due to higher energy demand for cooling.
  • Where you live: Energy supply rates change from state to state and even among utility areas in the same state, regardless of whether the state has energy choice.
If you are confused about any of the terms used, check out the Choose Energy glossary to learn more.

The Future of Energy

Energy comes from many sources, including coal, natural gas, nuclear and renewables. As nonrenewable sources such as coal diminish, the need for renewable energy sources grows. Some states satisfy the country’s growing renewable energy needs with their production of wind, solar and hydropower.
