"The 10-unit, 446-megawatt (MW) station first began producing power toward the end of 1921 under its original name, the Queenston-Chippawa Hydroelectric Plant. It was renamed after Sir Adam Beck in 1950 on the 25th anniversary of his death." At the time, it was the largest in the world.

"More than a century later, Sir Adam Beck I GS and its dedicated employees are still powering Ontario’s economy and net-zero efforts as part of a larger complex of hydro operations, which includes the 1,516 MW Sir Adam Beck II GS and the 174 MW Sir Adam Beck Pump GS. The entire generating complex produces about 12,300 gigawatt-hours of energy each year – about 40 per cent of OPG’s hydroelectric production, or about nine per cent of Ontario’s energy needs."

Bob Featherstone: The part above the floor is only the excitation system of each unit. The generators are on the level below this floor.

Here is a photo of the construction of the new units. Does anyone have a photo of the units in service?

The original Queenston-Chippawa generating station under construction in the early 1900s. It was renamed for Sir Adam Beck in 1950 to mark the 25th anniversary of the death of Ontario’s great champion of hydroelectric power during the early 1920s.
"Over the years, most of the station’s original units have been replaced with more efficient generators, and there are plans for the future to replace two of the last remaining historic units, the G1 and G2 turbine-generators, to ensure many more decades of affordable, clean power."

Sir Adam Beck #2 was built in phases. [NiagaraFallsInfo_station2]
Generators: Units 11, 12, 13, 14, 15, 16 and 17 went into service in 1954.
Generators: Units 18, 19, 20, 21 and 22 went into service in 1955.
Generators: Units 23 and 24 went into service in 1957.
Generators: Units 25 and 26 went into service in 1958.
Sir Adam Beck #1 taught me that the date of the first phase is used to date the power station. Originally, the generators were 25hz instead of 60hz. [NiagaraFallsInfo_station1]
Generators: Units #1, #2 and # 4 went in service on 26 January 1922.
Generators: Unit #5 went into service in 1923.
Generators: Units #3, #6 and # 7 went into service in 1924.
Generators: Units # 8 and #9 went into service on December 5th 1925.
Generators: Unit #10 went into service in July of 1930.
A hydro canal was dug for #1, but #2 uses two 14m (46') tunnels to carry the water from upstream of the falls. [NiagaraFallsInfo_station2]

I think the inlet for the tunnels are in this bay

Several references refer to "the international treaty." But none of them explain it. From memory from over 50 years ago from a Popular Science article, the treaty says that the Canadian and American power companies can divert a lot more water from the Niagara Falls at night than they can during the day. The reason they can't take a lot of water during the day is to avoid reducing the tourist spectical of water flowing over the falls. Unfortunately, people use more power during the day than they do during the night. So they built a 750 acre water reservoir. During the night they use the increased power generation to pump water into the reservoir. During the day, they release water from the reservoir to offset the water that is sent over the falls. Fortunately, the function of the pumps can be reversed and they generate power when the water is released. So the pumps increase the generating capacity of the plant during the daytime when demand is higher.

"This treaty spelled out for the first time how much water could be diverted from the river for hydro generation. It specified that a minimum 100,000 cubic feet of water per second would flow over the Falls during the day, while at night this flow would be reduced to a minimum 50,000 cubic feet per second." [NiagaraFrontier]

Because OPG has retired some of its older power stations, it was no longer using all of the water it has been allocated. And the power plant has been upgraded so that it can handle more water and generate more power. So a third water supply tunnel was finished in 2011. [power-technology]

"The 150m [492'] long, 14.4m [45'] high and 4,400t Big Becky is the largest hard rock TBM ever built."

The third tunnel increased the capacity by 194mw. [EnergyTariffExperts]

Proudly presents guest speaker Mr. Peter Mulcaster at its next
meeting Monday June 5th. 7 p.m.
Mr. Mulcaster is a retired professional Engineer currently engaged
in writing a book about the extraordinary achievements surrounding
the construction of the Sir Adam Beck #1 Generating Station.
The presentation is entitled
"The Queenston-Chippawa Power Development"

R.S. Doublas posted two images with the comment: "It looks like a lot of work is going on at the Sir Adam Beck plants. There's scaffolding along the wall and a whole maze of it below. I included the video because it shows water draining down the wall, which I'd never seen before."
William Wilson: I wonder if that's the start of what's to come they're supposed to be draining the hydro canal at some point I think I have delayed due to COVID and that hasn't been done since I believe in the '80s early 80s they'll have to close the gate at McLeod road and the one up by the lake they store in and then they're going to drain the entire hydro canal throw it all the debris and yes probably the bodies and stolen property but it should be a sight to see.
