Does EIA have information on the service territories of U.S. electric utilities?

EIA has the names of the counties, by state, in which electric utilities have equipment for the distribution of electricity to ultimate consumers. This information can be used as a rough approximation of a utility's service territory. One or more utilities may have distribution equipment in the same county.
