What You'll Learn
Niagara Falls' electricity generation
The use of Niagara Falls for electricity generation has a long history. While mills have used water from the Falls as a source of hydraulic power since 1759, the Falls were first used to generate electricity in 1882. The Niagara Falls Hydraulic Power & Manufacturing Company, which had constructed a canal for hydraulic power generation 20 years prior, began operating a small electrical plant in Niagara Falls, New York, that year. This plant generated direct current (DC) and could only distribute current to a 2-mile radius. However, it demonstrated the potential for hydroelectric power from Niagara Falls.
In the mid-1800s, Nikola Tesla developed a system of alternating current (AC) that enabled the transmission of electricity over much longer distances. Inspired by a photo of Niagara Falls as a young boy, Tesla became fascinated by the potential to harness the force of the powerful water. He designed and built the first hydroelectric power plant at Niagara Falls, which began producing electrical power in 1895. This marked a major milestone in the development of electrical power generation and the electrification of the United States and the world.
Today, Niagara Falls continues to supply electricity to the region, contributing to the power supply of New York State and Canada. It is currently New York State's biggest electricity producer, providing up to 2.6 million kilowatts of clean electricity per year. The power generated at Niagara Falls comes from several plants, including the Robert Moses Niagara Hydroelectric Power Station in Lewiston, New York, and the Sir Adam Beck Generating Stations in Niagara Falls, Ontario, Canada. These plants utilise the power of the water flowing over the Falls to turn turbines and generate electricity. The water is then returned to the lower portion of the Niagara River, ensuring a continuous and sustainable source of energy.
The Niagara Parks Power Station, located at the bottom of the Falls, offers a unique perspective on this history of power generation. Visitors can explore the former power station, which has been repurposed with interactive exhibits and installations that showcase the story of hydropower at Niagara Falls.

Nikola Tesla's hydroelectric power plant
Nikola Tesla designed and built the world's first hydroelectric power plant at Niagara Falls, New York, marking a significant milestone in the evolution of electrical power generation. The plant began producing electrical power in 1895, kickstarting the electrification of the United States and the world.
The development of this hydroelectric power plant was a culmination of Tesla's fascination with harnessing the power of Niagara Falls, which began when he saw a photograph of the falls as a boy in modern-day Croatia. The falls presented an opportunity to harness the force of powerful water and generate electricity for long-distance transmission.
Before Tesla's intervention, electricity was transmitted via direct current (DC), which was limited in distance and could only power a lightbulb. Tesla's genius lay in creating an alternating current (AC) system, which enabled the transmission of power generated at Niagara Falls to various locations. This AC power became the standard for modern infrastructure, allowing a plant in one location to serve multiple cities tens of miles away.
The Niagara Falls Hydraulic Power & Manufacturing Company had constructed a canal for hydraulic power generation and operated a small electrical plant in Niagara Falls, New York, in the late 1880s. However, it was Tesla's system that truly unlocked the potential of hydroelectric power at Niagara Falls.
Today, Niagara Falls continues to generate a significant amount of electricity for the region, supplying power to Buffalo, New York City, and various entities, including state facilities and utilities. The falls receive water from four of the Great Lakes and erode at a rate of about one foot per year. The power generated at Niagara Falls contributes to the electricity supply in both the United States and Canada, showcasing the enduring impact of Tesla's pioneering work in hydroelectric power generation.

The Northeast blackout of 1965
On November 9, 1965, one of the biggest power failures in history occurred, plunging all of New York state, portions of seven nearby states, and parts of eastern Canada into darkness. The Northeast blackout of 1965 began at the height of rush hour, affecting over 30 million people and 80,000 square miles of land. The failure was caused by a small, local disturbance that cascaded into a massive blackout.
The blackout started with a protective relay tripping on one of the transmission lines from the Sir Adam Beck Hydroelectric Power Station No. 2 in Queenston, Ontario, near Niagara Falls. The safety relay was set to trip if other protective equipment deeper within the Ontario Hydro system failed to operate properly. On a particularly cold November evening, power demands for heating, lighting, and cooking were pushing the electrical system to near its peak capacity. This protective relay tripped a 230-kilovolt transmission line near Ontario, Canada, at 5:16 p.m., causing several other heavily loaded lines to fail as well. This precipitated a surge of power that overwhelmed the transmission lines in western New York, causing a "'cascading' tripping of additional lines," eventually breaking up the entire Northeastern transmission network.
The power failure caused widespread anxiety and highlighted the vulnerability of certain critical services to power failures. Airports and hospitals, in particular, were affected, and surgeons had to complete operations by flashlight or candlelight. To deal with unexpected power outages, the Federal Power Commission (FPC) recommended that airports and hospitals install emergency generators, and that public buildings provide emergency lighting in stairwells and elevators.
