What Associated Electric Cooperative does

Associated Electric Cooperative Inc. (AECI) is a member-owned, not-for-profit wholesale power generation and transmission cooperative founded in 1961 and headquartered in Springfield, Missouri. It generates and transmits wholesale electricity through a three-tiered cooperative system: six G&T (generation and transmission) cooperative member-owners receive wholesale power from AECI, then transmit to 51 distribution cooperatives serving more than 935,000 member meters and approximately 2.1 million people across Missouri, northeast Oklahoma, and southeast Iowa.

The generation fleet is diversified and includes coal-fired baseload facilities (Thomas Hill Energy Center, New Madrid Power Plant), combined-cycle natural gas plants (St. Francis, Chouteau, Dell), simple-cycle peaking units (Unionville, Essex, Holden, Nodaway), 1,240 MW of contracted wind capacity across Kansas, Missouri, and Oklahoma (as of 2020), and a U.S. Department of Energy hydropower allocation. The transmission network spans more than 10,000 miles of high-voltage infrastructure with 230+ interconnections. Two new natural gas-fired simple-cycle peaking energy centers are under construction: Ripley Energy Center (~420-445 MW, ~$520M project cost) in Oklahoma targeting 2026 commercial operation, and Turney Energy Center (~420-445 MW) in Missouri targeting 2027; both feature quick-start capability and hydrogen-ready combustion turbines designed to burn up to a 30% hydrogen blend.

The business model is wholesale power supply priced on a cooperative cost-recovery basis rather than market-based rates; AECI's rates are set by member governance to cover operating costs and maintain financial strength, with investment-grade credit ratings (AA- Fitch, Aa3 Moody's, AA S&P). Revenue also includes off-system sales into adjacent markets when conditions are favorable, and member service programs such as Take Control & Save® (energy efficiency rebates, $74M+ invested since 2008) and Power4Progress (economic development and load-growth support).
