How are you getting from that to "China pays more for power than American industry"? Could you do a summary in one place? Your links seems to support the opposite conclusion but maybe you've got something going on across a few comments that I've missed.
I also went to look at the absolute numbers out of interest and China produces 8 PWh total and the US 4 PWh total according to [2] and playing around with the "Electricity production by source" graph. Although obviously that means per-capita the US is still a way ahead.
