Since its formation in 1961 by six generation and transmission cooperatives, Associated Electric Cooperative has grown under the leadership of its member-directed board and management. Throughout its history, Associated’s mission-driven strategies have kept the cooperative focused on providing an economical and reliable power supply and support services to its members.
The historical timeline below shows key projects in the development of Associated from humble roots to one of the nation's largest G&T electric cooperatives.

REA history
In 1935, President Franklin D. Roosevelt signed an executive order creating the Rural Electrification Administration (REA). A year later, Congress gave the agency the money and power needed to promote rural electrification by providing low-cost loans to build transmission and generation facilities.
Rural cooperatives formed rapidly to take advantage of the favorable financing. Farm by farm, village by village, the lights went on across rural Missouri and rural America. Eventually, Associated’s major generation facilities, built primarily during the 1960s and 1970s, were financed with help from the REA.
The electrification of rural America often is described as the single most dramatic event to touch the daily lives of this country’s farming families. It helped make this nation’s agriculture industry the most productive in the world and enabled the rural economy to grow in even more unexpected ways.

1930s through 1950s: The beginning
By the mid-1930s, just 6.4% of the farms in Missouri had electricity. Rural Americans simply didn't have the economic clout to obtain the one commodity that, more than anything else, could increase production and improve the quality of their lives – electricity.
1935: To encourage rural development, President Franklin D. Roosevelt signs an executive order creating Rural Electrification Administration (REA).
1936: Congress passes the Rural Electrification Act of 1936.
1941-1952: Associated’s six G&T owners are created: KAMO Power, Sho-Me Power Electric Cooperative, M&A Electric Power Cooperative, Northeast Missouri Electric Power Cooperative, Central Electric Power Cooperative and NW Electric Power Cooperative Inc.

The 1960s: Associated formed to supply power to members
The 1960s were a decade of birth, establishment and growth for Associated and rural power supply.
1961: Fifteen incorporators sign articles of incorporation to create Associated Electric Cooperative Inc.
1962: After approval from the REA and the Department of the Interior, Associated officially begins operations.
1965: Associated builds its first transmission line, a 1.5-mile tie line between M&A Electric Power Cooperative and Union Electric.
1966: Associated’s first power plant, Thomas Hill Unit 1, begins operations.

The 1970s: Negotiations reap highest ever REA loan
The decade of the '70s was challenging due to energy usage growth, changing government regulations, increasing inflation and high interest costs.
1972: New Madrid Power Plant's first unit goes online. Unit 2 follows in 1977.
1979: Associated negotiates with REA for the largest loan guarantee in the history of the rural electrification program: $1.4 billion to pay for Thomas Hill Unit 3; Black Fox Nuclear Project; new mining operations; and to offset double-digit interest rates in the late 1970s.

The 1980s: Associated expands mines, reduces coal costs
Expansion at Thomas Hill Energy Center dominated the scene during the 1980s as Associated brought on its fifth generating unit and modernized a newly purchased coal mine. Construction efforts during the decade were the largest in the cooperative's operating history.
1982: Thomas Hill Unit 3 begins operations.
1989: Associated forms its Clean Air Act contingency fund to help pay for changes at its power plants required by the 1990 Clean Air Act Amendments.
-
The 1990s: Natural gas diversifies plant operations
National news of budget cuts, layoffs and mergers dominated industry reports. Even rural electric cooperatives, once insulated from such pressures, felt the threat of competition. Strengthening its competitive position became a priority for Associated.
1995: The conversion to low-sulfur coal at both Thomas Hill and New Madrid power plants is completed, reducing sulfur dioxide emissions by 90% and allowing Associated to implement an average overall rate reduction of 17%.
1996: Associated announces a partnership to construct gas-based power generation facility St. Francis Power Plant.
1999: The first units of a 1,633-megawatts construction phase of gas-based generation come online to meet members’ peak demand needs. Intermediate and peaking power plants that begin operations in the next four years are Essex and Nodaway power plants, St. Francis, Chouteau Power Plant and Holden Power Plant.

The 2000s: Wind blows into generation resource mix
The 2000s brought continued diversification of Associated's generation mix, new emissions controls and environmental projects, positively leading to carbon emissions declines and the first utility-scale wind farm built in Missouri.
2000-2002: Selective catalytic reduction equipment, designed to reduce emissions of nitrogen oxides by about 93%, on New Madrid Unit 1 and 2 become operational.
2005: Associated purchases Dell Power Plant, a combined-cycle natural gas-based power plant in Dell, Ark.
2006: Associated was named “2006 Wind Co-op of the Year” for helping make Missouri’s first utility-scale wind farms a reality.
2007: Associated receives two national awards for its innovative reclamation of the Bee Veer Mine in Macon County, Mo.
2008: $424 million construction project installs selective catalytic reduction equipment at Thomas Hill Energy Center, enabling a 90% systemwide reduction of nitrogen oxides (NOx) emissions by Jan. 1, 2009, the Clean Air Interstate Rule deadline.
