History of Niagara Falls Power Development
The history of power development at Niagara Falls can be traced back to 1759, when Daniel Joncairs became the first person to harness power from the falls by digging a narrow ditch above them to turn a waterwheel and power a sawmill. However, it wasn't until the late 19th century that Niagara Falls became a significant source of electricity.
In 1892, The Canadian Niagara Power Company (CNP) was incorporated, and it built a hydroelectric generating plant 457 metres above the Horseshoe Falls. This plant began generating electricity on January 1st, 1905, and was inaugurated as the William Birch Rankine Power Station in 1927. The Rankine Power Station provided its first long-distance electricity to the Village of Fort Erie in 1907, 36.6 km from Niagara Falls.
In 1896, the Niagara Falls Power Company, then known as the Niagara River Hydraulic Tunnel Power & Sewer Company, formed to implement Evershed's plan for power generation. Under the leadership of financier Edward Dean Adams, the company harnessed power from the falls, and on November 18, 1896, Niagara Falls' first power plant came online, with Nikola Tesla playing a key role in harnessing electricity from the falls. Within a few years, the electricity generated was powering elevated railways and streetlights in New York City.
In 1961, the Niagara Power Project, including the Robert Moses Niagara Hydroelectric Power Station, became the largest hydropower facility in the western world, producing up to 2.6 million kilowatts of clean electricity per year and supplying one-quarter of all power used in New York State and Ontario. Today, the Sir Adam Beck Generating Stations in Ontario and the Robert Moses Generating Station in New York are the largest generators of hydroelectric power in North America.

How Hydroelectric Power Works
Hydroelectric power is a process that uses the force of falling water to generate electricity. This is typically achieved by building power plants around waterfalls, taking advantage of the drop in water and the power of gravity. While waterfalls can be tapped directly by installing a water wheel into the falling water, this method is risky as the water flow can vary, and debris can hit the wheel.
Hydroelectric power plants usually divert water from the stream of a river, storing it in reservoirs for when water flow is low. The water is then run through a turbine, which is driven by the force of the falling water. The spinning turbine generates electricity.
Niagara Falls is surrounded by dams and pumps that divert water from the river upstream from the falls to reservoirs. The International Control Dam and a system of pumps divert the river through large underground tunnels to the Sir Adam Beck and Robert Moses Niagara Reservoirs. Both reservoirs sit on cliffs above the river, with the power plants located between them and the river. The Lewiston Dam, for example, contains a man-made reservoir that stores water pumped into it from the forebay of the Robert Moses Power Station. Water in the forebay can be pumped into the reservoir for later use, or sent immediately through the Robert Moses Power Station turbines.
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. It diverts water from the Niagara River above the falls and returns it to the lower portion of the river near Lake Ontario. The plant uses 13 generators with an installed capacity of 2,525 MW.

Niagara Falls Power Plants
The Niagara Falls Power Plants have harnessed electricity from the Falls since the late 1890s, when Nikola Tesla developed a system to generate electricity. The Falls are surrounded by dams and pumps that divert water from the river upstream from the falls to reservoirs and other dams downstream. This water is then dropped through turbines to generate electricity.
The first power plant at Niagara Falls opened on November 18, 1896. Within several years, the Falls were able to power the elevated railways and streetlights of New York City. The alternating current discovered by Tesla still powers homes and offices across New York State today.
The Niagara Power Project, which includes the Robert Moses Niagara Hydroelectric Power Station, was the largest hydropower facility in the western world in 1961. It is currently New York State's biggest electricity producer, providing up to 2.6 million kilowatts of clean electricity per year. The Robert Moses Power Plant diverts water from the Niagara River and returns it to the lower river near Lake Ontario. It uses 13 generators with an installed capacity of 2,525 MW and an average annual net generation of 15,897,000 MWh between 2014 and 2023.
The Sir Adam Beck Generating Station Plant #2 in Ontario and the Robert Moses plant in New York are connected by a small tramway that traverses the Niagara River Gorge. The Lewiston Pump-Generating Plant, which houses the Robert Moses Power Station, contains 12 electrically powered pump-generators that can generate a combined 240 MW when water in the upper reservoir is released.
The Niagara Falls Hydraulic Power & Manufacturing Company opened a small electrical plant in Niagara Falls, New York, in 1882, though it produced little electricity. In 1886, the competing Niagara Falls Power Company built the Adams Power Plant, and between 1900 and 1904, the Powerhouse No. 2, bringing its total generators to 21, with a total capacity of 78 MW.

Niagara Falls and Nikola Tesla
As a child in modern-day Croatia, Nikola Tesla saw a photograph of Niagara Falls and dreamed of using the waterfall to generate power through hydroelectricity. In 1893, Tesla began working on this dream when he started developing the world's first hydroelectric power station with George Westinghouse.
At the time, electricity was transmitted by direct current, which could only travel about 100 yards or power a single lightbulb. Tesla wanted to develop a system of alternating current that would yield more power and travel much longer distances.
In 1895, electricity transmitted from Niagara Falls reached a nearby factory. The following year, in 1896, the Edward Dean Adams Power Plant, based on Tesla's AC power system, was built on the upper Niagara River. The first power surge from Niagara Falls, New York, to Buffalo, New York, was transmitted that same year.
The Edward Dean Adams Power Plant was later renamed the Edward Dean Adams Power Station in 1927 after the president of the company that oversaw its construction. Today, all that remains of the complex is The Adams Power Plant Transformer House, located on Buffalo Avenue and listed on the National Register of Historic Places.
Niagara Falls is currently New York State's biggest electricity producer, providing up to 2.6 million kilowatts of clean electricity per year. The power generated by the Falls has been used to power the elevated railways and streetlights of New York City, and it still powers homes and offices across the state.
