2. Sir Adam Beck Hydroelectric Generating Stations

3. INTRODUCTION The Sir Adam Beck complex is situated on the downstream side of Niagara Falls on the Canadian side of the Niagara River Country Canada Location Niagara Falls, Ontario Status Operational Commission date Adam Beck I 1922, Adam Beck II 1954 Owner(s) Ontario Power Generation

4. Power generation Units operational 26 (Adam Beck I 10, Adam Beck II 16)  Capacity 1,997 MW (2,678,000 hp) Consists of the conventional 437-MW Sir Adam Beck 1 and 1,499-MW Sir Adam Beck 2 power stations and the 174-MW Sir Adam Beck Pump Generating Station The stations divert water from the Niagara and Welland Rivers above Niagara Falls which is then released into the lower portion of the Niagara River, and together produce up to 1,997 MW (2,678,000 hp).

6. Sir Adam Beck Station #1 Adam Beck I  was originally called the  Queenston-Chippawa Hydroelectric Plant  and was renamed after Adam Beck in 1950 on the twenty-fifth anniversary of his death. Adam Beck I contains 10 generators and first produced power in 1922. POWER CANAL The water is diverted through the Chippawa-Queenston Power Canal from the Welland River to the plant  The concrete trapezoidal section of the canal is 93.6 meters wide at the surface and 56.4 meters wide at the base. The water flows at a rate 62.3 cubic meters per second. The canal ends at the giant forebay built at the entrance to the Sir Adam Beck #1 power station

8. PENSTOCK At the entrance to each penstock, there are three openings. Each opening has a set of service gates and trash racks that protect the turbines below from being damaged or clogged by large objects At the base of each penstock is a valve that regulates the water flow before entering the turbine. Number of Penstocks 10 Material concrete encased, steel penstocks Length 116.7 meters Diameter 4.9 meters

13. Sir Adam Beck Power Station #2 Sir Adam Beck Power Station #2 was located just south of Beck Power Station #1. It would require three times as much water. Contains 16 generators and first produced power in 1954 Sir Adam Beck #2 Power Station is 875 feet (266.7 m) long.

14. INTAKE TUNNEL Water to the Sir Adam Beck Power Station #2 is provided by twin intake tunnels . The intakes are located in the Niagara River at Chippawa . Water was diverted from the upper Niagara River at Chippawa by intakes that are square tubes and are oriented parallel to the Niagara River. Similar in shape to a square, they vary in area from 20 feet (6m) square at the upriver end to 45 feet (14m) square at the downriver end . Each 650 feet (200m) long tube has 30 intake ports. Piers separating these ports channel intake flow along the tubes.

15. The 45 feet (13.7m) square sections leads to the control gates. The control gates ; one for each tunnel are 58 feet (18m) high and 45 feet (14m)  wide. Beyond the gates, the square tubes change from square to circular. Covered conduits 370 feet (113m) long and 45 feet (14m)) in diameter lead to the tunnels which are of the same diameter. Each tunnel was located 250 feet (76m) apart.

19. The tunnels have a finished diameter of 45 feet (13.7m). The concrete tunnel lining is about 3 feet thick (1m). The tunnels terminate into an open cut canal. The water is channeled through a 2,200 feet long (670.5m) concrete lined trapezoidal section An open cut channeled water to the Sir Adam Beck Power Station #2 forebay the remaining 2.25 miles (3.6 kms ). The Average width of this canal is 200 feet wide (60m). Water flows at a rate of 7-8 feet per second (2.1 m/s) and has a depth of 28 feet (8.5m).

20. As the water enters the forebay the flow of the water is reduced to 3 feet per second (1m/s). PENSTOCKS Number 16 Material Concrete encased steel penstocks Length 492 feet (150m) Diameter 16 feet (5m) vertical drop 292 feet (89m).

21. At the head of each penstock are trash racks and two motor operated steel gates. In an emergency, these gates can be closed by remote Water is pumped into the reservoir at night by use of 6 - 30 megawatt pumping/generating units. During the day, when water flow is increase to the Falls, water is released from the reservoir to compensate for this. As the water is released from the reservoir the pumps turned generators produce electricity as well. Each unit having an output of 47,000 horsepower at a maximum discharge of 5,600 cubic feet per second.

22. Each generator is 50 feet (15m) in height and rotates at 150 revolutions per minute. The revolving parts weigh 500 tons. The 16 generators are housed in a building almost twice as long as plant #1 and has a capacity of1499MW.
