Looks like the EIA is figuring the total bill for some 'typical' customer, so you get the actual per-kWh cost plus the fixed service cost divided by whatever they think 'typical' use is.
This is the actual residential tariff sheet: https://www.georgiapower.com/content/dam/georgia-power/pdfs/tariffs/r.pdf
$0.082/kWh most of the year, $0.087 summer, rising to ~$0.15 if you use over 650 kWh/month (which is a lot: my 3 br house tops out under 600 in Aug). Taxes & fees around 20%, so effectively $0.098 & 0.104. The kicker is the fixed service charge of $0.46/day = $16/month after taxes, effectively a 5.6 kWh/day minimum. That's the part they've been raising. Commercial & industrial users pay proportionally less fixed fees, so their 'typical' kWh cost is lower.
