Explanation of New Terminology for Sales and Revenue Data Changes in the electric utility industry and to the Energy Information Administration's (EIA) data collection process have resulted in some new terminology. Below is an explanation of the new terminology used by EIA for sales and revenues reported by U.S. electric utilities. Full Service Sales - (also referred to as "bundled" sales) are sales by a utility to a customer where the utility provides both the energy and the delivery service. Note that a utility can provide energy either by generating power or by purchasing wholesale power to sell to its customers. These full service sales occur in states that have not enacted retail choice as well as in retail choice states when the customer elects to remain with the standard provider for both energy and delivery service. Energy Only Sales - in retail choice states, this is the power supply portion of the customer's bill if the customer chooses a supplier that is not the standard provider for its service territory. Delivery Only Sales - in retail choice states, this is the distribution portion of the customer's bill if the customer chooses a supplier that is not the standard provider for its service territory. (When a customer in a retail choice state elects to receive energy service from a provider other than the local utility, then the local utility providing the delivery service records the sale as a "delivery only" sale.) Unbundled Sales -the sum of the delivery only sales and the energy only sales. Since the energy service suppliers are required to report their sales to customers grouped by the state where the customers reside, unbundled sales can only be summed on a state or national level. The methodology used by the Energy Information Administration is: Delivery Only Revenue + Energy Only Revenue Energy Only Sales (Mwh) Other notes on the data: In theory, the "Delivery Only" MWH sales and the "Energy Only" MWH sales should be equal in every state. However, for many states, the 2003 data reported by utilities and power marketers show large differences in the Energy Only MWH sales and the Delivery Only MWH sales. EIA has made adjustments to unbundled revenue or sales data in the states for which there were significant differences in sales reported by energy only and delivery only providers.
