Each dot is one of the 31 South Carolina utilities reporting both a residential price and residential sales in 2024, placed by its rank percentile within that group rather than its raw value, so one very large utility cannot flatten the rest. Bubble size follows customers served, rank-scaled so a utility with millions of customers cannot swamp the rest. South Carolina Public Service Authority is highlighted. In South Carolina the cheapest rate and the smallest implied annual bill happen to belong to the same utility, Greenwood CPW; across the country they usually do not. 2×2 strategic matrix plotting 31 entities by Price rank percentile (100 = most expensive in state) (X) and Consumption rank percentile (100 = heaviest use) (Y), with a crosshair dividing the plot into four quadrants.

What is the average electricity bill for South Carolina Public Service Authority customers?
Dividing reported residential sales by residential customers gives about 11,335 kWh per customer per year. At the reported average price that implies roughly $1,290 a year, or about $108 a month. This is RateWatt's arithmetic on two EIA columns, not a figure EIA publishes.
