I just got off the 'phone with my electricity provider. I was looking at my bill and computing I was paying 12.5 cents/kwh, I inquired as to why I shouldn't switch to another provider, some offering power as low as 9.5 cents. He explained.
I was actually paying 8.8 cents (!) but the various add-on fees (which other providers would have also) drove up the final price. These add-on fees consisted of a delivery charge by another company, sales tax, Spanish-American War tax, infrastructure recovery fees, and assorted nickel-and-dime supplements.
He did find me another plan that dropped the overall rate, though.
Point is, don't fall for the "basic energy charge" quote compared to the total charge.
Aside: I've found that fussing about your bill to almost anybody will usually result in a price reduction.
