The potential power of Niagara Falls attracted industrialists who worked to harness its force using water wheels to drive their mills and factories. The world’s first large-scale hydroelectric generating station opened in Niagara Falls in 1895. The plant used the direct current (DC) system, however, which could only transmit electricity 100 yards.
In 1896, the famous electrical engineer, Nikola Tesla, proved that he could transmit electricity from Niagara Falls to Buffalo using his new alternating current (AC) induction motor. That marked the first long distance commercial use of the AC system that is still used around the world today. Electricity was first sold as a commodity at the now-ruined Schoellkopf Power Station.
Hydroelectricity is one of Niagara Falls’ most important products. Together, power plants on both the American and Canadian sides of the Falls have the capacity to produce up to 2.4 million kilowatts of electricity. Under an international treaty, the flow of water over Niagara Falls is reduced during the night to allow more of the water to flow into the intakes used for power generation. This plan ensures that the Falls’ natural beauty remains unaffected during prime viewing hours.
