Dixie Electric Membership Corporation (DEMCO), now the largest electric cooperative in Louisiana in terms of number of meters, was formed in August of 1938. At that time, the cooperative served about 750 members in the three parishes of East Baton Rouge, East Feliciana and Livingston.
DEMCO is one of the largest local businesses in this region of the state, and currently serves over 109,000 meters in seven parishes of Southeast Louisiana, including: Ascension, East Baton Rouge, East Feliciana, Livingston, St. Helena, Tangipahoa, and West Feliciana. DEMCO's integrated electric distribution system covers 15,000 square miles. DEMCO is one of the fastest growing cooperatives in the nation.
