On February 2, 1948, Northeast Power was founded by three rural electric cooperatives in northeast Missouri. This entity originally relied on purchased power from the US Bureau of Mines plant in Louisiana, Missouri.
In 1961, Northeast Power joined with five other generation and transmission cooperatives in Missouri to form Associated Electric Cooperative, Inc. The goal was to place existing and future generation, along with transmission facilities, under one operating unit. Associated is now one of the nation's largest wholesale power suppliers and maintanes rates that are among the lowest in the United States.
Currently, Northeast Power is a generation and transmission cooperatives comprised of eight Member-Distribution Cooperatives with five located in Northeast Missouri and three in Southeast Iowa.
