ENRGY CHARGE
baseline winter: 502kwh x $0.04031 $20.24
over baseline 1%-30% 95kwh x $0.04185 $ 3.98
----------------------------------------------------------
Delivery subtotal $24.75]
Basically you get charged the same amount for your kwh as long as you don't go over the baseline (in your case the baseline is 502kwh). They charged you 4.031 cents per kwh for the first 502kwh's and then charged you more, at 4.0185 cents per kwh , for the next 95 hours because you went over the baseline kilowatts allowed.
(502*4.031= $20.24)
(95*4.0185=$3.82)
(20.24+3.82= $24.06)
So that's how they got your subtotal.
Just keep payin' the bill because you know what's coming! -->
