DOWNLOAD DATA ARCHIVE: Average Revenue per kWh by Customer Class 2016-2019

 

Table 2, drawn from 2019 EIA data, shows the average monthly bill for residential customers in the US by state. The data shows that even though the $144.73 average monthly electric bill in SC is high compared to other states, the average price per kWh in 2019—12.99 cents-- is below the national average. It is important to note that unlike other areas of the country, the majority of homes in South Carolina 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.
