"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."

| CapitalCurrent, Photo courtesy Ontario Power Generation 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]

The Niagara Hydro Tunnel Gates..up the boulevard from the International Control damn located in the upper river above the falls.What you are looking at are the gates that open and close two tunnels 13.7 metres in diameter that carry water to the forebays of the Sir Adam Beck Generating Stations ten kilometres downstream at Queenston. The tunnels pass under the city of Niagara Falls, Ontario and they are about 101 metres below ground. They can transport water at 2850 cubic metres per second. Niagarans that have houses located above these tunnels say when it is really quiet outside they can hear the flow of water below their houses!Two similar Hydro Gates are located in Niagara Falls, N.Y. These tunnels transport water to the reservoir above the Robert Moses Power Plant at Lewiston N.Y.My dad would always say, oh dear, the movies over, maybe next time...he was a comedian...he took hundreds of photos of FOL and many were the red bells that looked like they were chiming...I'll keep looking, I know they are in his bins of pics..

This is the new tunnel that was built from 2005-2013 50ft diameter. I worked in there the last 3 years until the opening date.

Saint David's Buried Gorge is an ancient pre-glacial river bed that existed 22,800 years ago on the present-day Niagara Peninsula. The ancient Saint David's River once flowed through this area prior to the advance of the Wisconsin glaciation during the Last Glacial Period. When the glacier retreated 12,000 years ago, the gorge and river valley were filled in with glacial silt and rocks. Approximately 4,200 years ago, the Niagara River intersected the buried gorge in the course of Niagara Falls receding toward Lake Erie. When the river encountered the glacial silt that filled the gorge, the river rapidly changed course to fill the ancient gorge and wash out most of the silt. This led to the formation of the Niagara Whirlpool. The Niagara River reclaimed the gorge and currently flows through part of the ancient gorge. The other part of the ancient gorge extends into Lake Ontario at a different point than the Niagara River. The gorge is estimated to be 4,000 ft (1,200 m) long, 1,000 ft (300 m) wide, and 300 ft (91 m) deep.In the 1950s, Ontario Hydro dug two tunnels from the upper Niagara River to supply water to the Sir Adam Beck Hydroelectric Plant. These tunnels had to surface when they encountered the St. David's Gorge, as the loose silt in it was unsuitable for tunneling. In 2013, an additional tunnel, the Niagara Tunnel Project, was completed. This tunnel was bored beneath the old gorge to avoid the unsuitable geology.

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]

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.
