About Us

ACEC’s geographic service area includes approximately 2,500 square miles in parts of 12 central Wisconsin counties (Adams, Columbia, Dane, Dodge, Green Lake, Jefferson, Marquette, Portage, Sauk, Waupaca, Waushara and Wood.)

Adams-Columbia Electric Cooperative is a community-focused electric cooperative created to efficiently deliver affordable, reliable, and sustainable energy to more than 39,458 homes, businesses, farms, and schools. Adams-Columbia Electric Cooperative is led by and belongs to the communities we serve.

Adams-Columbia was formed in 1987 following the successful merger between the former Adams-Marquette Electric Cooperative and the former Columbus Rural Electric Cooperative. In 1992, a second successful merger combined Adams-Columbia with the former Waushara County Electric Cooperative.

The cooperative’s headquarters is in Friendship, Wisconsin. ACEC also maintains operations facilities in Pardeeville and Wautoma. The organization is governed by a member-elected, 7-person board of directors.
