was formed. The
Cataract Construction Company, a new company formed to exploit the opportunity, led by president
Edward Dean Adams, first formed the International Niagara Commission in 1890 to come up with a plan for harnessing the Falls. The Commission favored electricity, but could not recommend a solution to Cataract.

In 1892,
George Forbes was hired as a technical consultant and in May 1893 he convinced the company to build a hydroelectric system based on
polyphase alternating current.

. Locally quarried limestone was used in its construction.
The transformer house was next to the power houses, which "built on the upper river, above deep excavations housing twenty-one generating units. Tailwater from the generators passed into a 7000-ft tailrace tunnel, which conveyed the water beneath the city to the lower river, near the present-day site of the Rainbow Bridge. The 18-ft by 21-ft tunnel required over 3 years to build, used more than 16 million bricks in a four-course lining. It also cost the lives of twenty-eight workers."
The Niagara Power Station No. 1, as it was then called, would eventually generate of electricity. There were 10 generator rated of the outside revolving field, vertical shaft type. The generators were separated into two banks of five generators each with independent switchboards. The output was at 2,000 volts to serve in and around Niagara Falls. There were transformers to step up the voltage to 10,000 volts to serve the medium distance around Niagara Falls areas. The voltage was also stepped up to 20,000 to serve the longer distance for
Buffalo,
Lockport, and
Tonawanda. The station was the model for a second similar station built in 1904. The entire plant was officially named after Edward Dean Adams in 1927.
The original Westinghouse generators remained in operation until the plant closed in 1961,
having been replaced by the
