Created by its members as a joint-action agency in 1977, Southern Minnesota Municipal Power Agency (SMMPA) generates and sells reliable wholesale electricity to its eighteen non-profit, municipally-owned member utilities, and develops innovative, nationally recognized high-efficiency products and services to help them deliver value to their customers. Though SMMPA member utilities are located throughout the state, most are in southern Minnesota. SMMPA members serve over 93,000 residential customers and over 11,000 commercial and industrial customers. The Agency's main source of electricity is its 41% share of the 884 MW Sherco 3 coal-fired generator near Becker, MN owned in partnership with Xcel Energy. In addition SMMPA’s resource mix includes an array of intermediate and peaking units owned by its Member utilities. SMMPA has aggressively developed renewable resources such as wind, biodiesel, hydro and waste-to-energy. Renewable generation in 2009 is in excess of 13%.
