The Saint Marys Falls Hydropower Plant (also known as the Edison Sault Power Plant , Michigan Lake Superior Hydroelectric Power Plant , and the Cloverland Electric Cooperative Power House ) is an 18-MW hydroelectric generating plant located in Sault Ste. Marie, Michigan (the "Soo"). It extracts water from the St. Marys River under the supervision of the Army Corps of Engineers , and the power is taken up and distributed by the Cloverland Electric Cooperative , a rural utility that serves the Soo area.
6-709: As of 2024, the Soo hydropower plant is one of the oldest large generating stations still operating in the United States. The power canal and generator complex were begun in September 1898 and completed in June 1902, using engineering work from the first iteration of large-scale electrical generation in the late 1800s. It was from this work that the plant and utility that grew up around it acquired their historic name of Edison Sault , although Thomas Edison did not himself build
12-698: A definitive agreement to sell Edison Sault Electric to the Cloverland Electric Cooperative of Dafter . Edison Sault's only generating station was the Saint Marys Falls Hydropower Plant located on the St. Marys River in downtown Sault Ste. Marie. During the night when demand was low, the company was able to sell power from this small dam to larger companies such as Upper Peninsula Power Company and Consumers Energy . Edison Sault's transmission system voltage
18-749: Is 138,000 volts. The subtransmission system voltage is 69,000 volts. The distribution system voltage is 13,200 volts. Edison Sault had four 138 kV interconnections with other utilities. Two were with Consumers Energy in lower Michigan. (McGulpin-Straits #1 and McGulpin-Straits #2) These two lines are submerged under the Straits of Mackinac . Edison Sault has two interconnections with its former sister company, Wisconsin Electric (Arnold-Indian Lake #1 and Arnold-Indian Lake #2). Edison Sault had interconnections with Cloverland Electric and Upper Peninsula Power on its 69 kV subtransmission system. This article about
24-526: The feeder canal that chutes water to the plant. President William Howard Taft visited the plant in 1911. The power canal and hydroelectric plant were together named a Historic Civil Engineering Landmark in 1983. Although the hydroelectric plant could generate as much as 25-30 megawatts if operating at full capacity, grid planners rate it at 18 MW.

30-598: The plant. The Soo hydropower plant was built to contain 74 generators under a single roof. This was done under the constraints of the Classical style , by building an industrial structure of 1,340 feet (410 m) in length parallel to the St. Marys River and facing the structure with masonry . The sandstone facing of the power station was chiseled out of blocks pulled from the Edison Sault Power Canal ,
36-701: Was a public utility that provided electricity to the eastern portion of Michigan 's Upper Peninsula . Its service area covered four counties ( Chippewa , Mackinac , Schoolcraft and Delta ). The company was founded in 1892 in Sault Ste. Marie . Wisconsin Energy Corporation acquired the Edison Sault Electric Company with its purchase of its parent company, ESELCO in 1998. In 2009, Wisconsin Energy announced it had reached
