What “bundled” means

Supply and delivery are reported together.

We only use a provider headline when EIA reports bundled residential service. That makes the annual figure more complete than an energy-only or delivery-only component, but it still does not reproduce the provider's current rate schedule.

Why this page is in the reviewed cohort

Observed data with a reported territory.

This page met our publication criteria for bundled service, observed data, customer scale, a valid price, and county service-territory coverage. We then selected this provider/state pair for the smaller curated utility cohort.
