1880 - 1900
Hydropower was a growing energy source in the U.S. Within the first 20 years of the first few plants, nearly 40% of America's electricity was being produced hydroelectrically.
First U.S. hydroelectric power plant
The first U.S. hydroelectric power plant opened on September 30, 1882 on the Fox river near Appleton, Wisconsin.
Plant Numbers Increase
In the U.S. and Canada there were between 40 and 50 hydroelectric power plants.
Companies Use Hydropower
About 200 electric compines relied on hydropower for at least a part of their generation.
Niagara Plant Opens
The Niagara Falls hyropower station opened. Originally it only provided electricity to the local area. But a year later, electric power from the falls was being sent to people over 20 miles away in Buffalo, New York.
First Federal Water Power Act
The first Federal Water Power Act required special permission for a hydroelectric power plant to be built and operated on any river big enough for boat traffic.
The Reclamation Act
In 1902, the Reclamation Act created the United States Reclamation Service, later renamed the U.S. Bureau of Reclamation. It was formed to manage water resources and was given the authority to build hydropower plants at dams.
Kilowatts of Electricity
The nations largest hydroelectric dam , the Grand Coulee , began operations
Hoover Dam begins operation
Hoover Dam befgan operation on the Colorado River. It produced up to 130,000 kilowatts of electricity.
