Residential electric supply rates in 2017

As of 2016, the average home in the U.S. consumed 897 kilowatt hours (kWh) of electricity per month. Bills vary by state and region, as cost per kWh differs. To estimate average 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 November for Virginians was 11.67 cents, which amounted to an average bill of about $104.68 9 (11.67 cents x 897 kWh) that month.

Commercial electricity rates in 2017

In states with energy choice, the open market is not only for residents. Businesses can also take advantage of pricing and plans available through an energy supplier. In some states, only business customers have energy choice. Across the United States in 2016, the average business consumed 6,278 kWh of electricity per month and received a bill of nearly $655.  

Commercial electric bills can vary greatly by industry and business. Although homes come in all shapes and sizes, businesses have larger variations with diverse needs – from industrial buildings to mom-and-pop businesses. In November, the average business in Utah paid 8.14 cents per kWh. With this number, we can deduce that on average companies in Utah paid $511.03 that month for electricity.

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 2016, Florida experienced the biggest fluctuation in Residential Energy Rate electric prices, while Oregon and Utah have 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.
