Method: cents per kWh = revenue (thousand dollars) divided by sales (megawatthours), times 100. Customer counts, sales and revenue are the utility's own annual survey responses by state and sector. Bundled = energy plus delivery from one utility; delivery-only = the wires charge for customers who buy energy from a competitive supplier; energy-only = a competitive supplier's energy charge without delivery.
