Transmission is different from distribution. The networks are different. Transmission leads into a substation at high Voltage, 100kV and up, think metal towers. Distribution leaves a substation and goes out on lower Voltages around 14kV or so, think wooden poles. Your power may not be generated by the utility. They may buy it from somewhere else and pay those fees for it. They then distribute it to you.

Not justifying the bill. Just giving some knowledge.
