Hydroelectric Power at Fort Peck Dam
Fort Peck Dam was not intended to produce hydroelectric power when it was originally designed in the early 1930s. After the dam was completed, powerhouses were added to help meet the nation's growing demand for electricity.
Water from Fort Peck Lake is diverted to the powerhouses to create hydroelectric power. When water hits the turbine, the pressure forces the turbine to spin like a giant waterwheel.
Construction began on powerhouse #1 in 1941 and was completed in 1951. It first generated power in 1943. Powerhouse #2 was completed in 1961. Combined, the powerhouses produce approximately one billion kilowatt hours of electricity each year, helping to provide power to approximately 400,000 people in Montana.
Erected by U.S. Army Corps of Engineers.
