DOWNLOAD DATA ARCHIVE: Average Revenue per kWh by Customer Class 2016-2017

Table 2, drawn from 2017 EIA data, shows the average monthly bill for residential customers in the US by state. The data shows that even though the $140.80 average monthly electric bill in SC is high compared to other states, the average price per kWh in 2017—13.02 cents-- is below the national average. For example, Hawaii’s average price/kWh is more than twice that of South Carolina, but the average monthly bill is lower by about $8.50, presumably because the climate requires less heating and less cooling. It is important to note that unlike other areas of the country, the majority of homes in SC are heated and cooled with electricity, contributing to higher use. Homes in other regions of the country use natural gas or other fuels, which are not reflected in electricity bills. According to the EIA publication Household Winter Heating in the US, using data drawn from the EIA 2017-2018 Winter Fuels Outlook, 64 percent of buildings in the South are primarily heated with electricity as compared to 34 percent in the West, 22 percent in the Midwest, and 16 percent in the Northeast.
