American Electric Power has joined WIRES as a full supporting member, expanding the group's diverse membership to 28 members. WIRES, a national non-profit organization, continues its educational work and advocacy for strong high-voltage electric transmission infrastructure across North America. Like AEP, WIRES members that operate facilities, or participate in power markets, across multiple jurisdictions recognize the need for consistent national and regional policies that foster infrastructure investment.

AEP owns the largest electricity transmission system in the United States. The network includes nearly 39,000 miles (62,764 km) of lines, including more 765-kV extra-high voltage transmission lines than all other U.S. transmission systems combined. AEP transmission directly or indirectly serves about 10% of electricity demand in the Eastern Interconnection and about 11% of demand within ERCOT in Texas. AEP's utility units operate as AEP Ohio, AEP Texas, Appalachian Power, AEP Appalachian Power, Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma and Southwestern Electric Power Co.
