Which utilities serve each county in West Virginia
About this data
Which utilities exist comes from the U.S. Energy Information Administration’s Form EIA-861 and EIA-861S, data year 2025 (final release, October 7, 2026), read directly from eia.gov. County service territories, balancing authority codes and customer counts come from EIA-861 for 2018, the latest year compiled at county level for this directory; utilities that started reporting after 2018 carry their 2025 values. County boundaries are U.S. Census cartographic boundaries (us-atlas 3.0, Albers USA projection).
Customer counts are per utility within West Virginia. A county’s grid operator is the one serving most of its customers, estimated by spreading each utility’s customers evenly over its counties. Download every state in one file from the U.S. Electric Utility Directory.
