The first electric power generated by the Theodore Roosevelt Dam for commercial use was transmitted over a high-voltage line to Phoenix, where it was employed to operate the city's new streetcar system.

These two water turbines were probably the largest and nearly the most powerful ever built in the United States, supplying direct mechanical power to a manufacturing plant. Their installation between 1871 and 1873 makes them among the oldest surviving water turbines.
A dam at Cohoes diverted water to mills and factories along a power canal system. The vertical-shaft turbines at the mill were said to run at 800 horsepower (600 kilowatt) under a head of 20 feet and were connected to an overhead shaft by bevel gearing.

This unit, retired from the Belle Isle Station of the Oklahoma Gas & Electric Company, was the first gas turbine to be used for electric utility power generation in the United States. It represents the transformation of the early aircraft gas turbine, in which the engines seldom ran more than ten hours at a stretch, into a long-life prime mover. This redesign was based upon creep-rupture tests of S-816 cobalt-base alloys for turbine buckets. The low-cost trouble-free service led to wide-scale adoption of the gas turbine, over 45 million kilowatt capacity (over 9 percent of U.S.
