Two generators are set to be replaced at Ontario Power Generation’s (OPG) Sir Adam Beck I Generating Station, adding a total of 106MW capacity.

The existing generators at the G1 and G2 units were decommissioned in 2009, meaning the eight remaining units at the original 10 unit station have a total combined capacity of 447MW.

"Nearly 100 years ago, the Sir Adam Beck I station in Niagara Falls helped set the standard for 25 Hz, which became the norm across North America,” said Gerry Foote, OPG’s Vice-President of Niagara Operations. “But there is no longer a demand for the 25 Hz power cycle, so it’s time to overhaul and upgrade these two units.

“The new generator units will be lighter and more efficient, and able to make more energy with less water required to pass through the turbine.”

The project is currently undergoing environmental assessment. Pending this review, planning would begin for installation, which would start in 2020 and last into 2022.

Several other upgrades are planned for Sir Adam Beck I GS as it approaches its 100th birthday in 2022. This includes refurbishment of the 13.7km Sir Adam Beck Power Canal that feeds the station water from the Niagara River.
