Workers traverse heights to successfully complete high-voltage line replacement at Sir Adam Beck II station
We have not done this kind of structural tower repair and painting at Beck II in more than 50 years. The project required significant planning with the contractor to determine the safest approach, especially as much of the work took place at great heights.Gordon JeungProject Site Manager
While keeping safety as the top priority, workers used boom lifts, cranes, and suspended ladders as they built scaffolding over Beck II’s penstocks, painted the transmission towers, and replaced insulators and power lines that have reached the end of their service life.
The project started in execution in late September and was completed ahead of schedule and on budget in October.
“We have not done this kind of structural tower repair and painting at Beck II in more than 50 years,” said Gordon Jeung, a Project Site Manager at OPG. “The project required significant planning with the contractor to determine the safest approach, especially as much of the work took place at great heights. There was a large team at OPG that played an integral role in making this project successful.”
The project required significant planning by OPG’s Projects Department and support staff, in addition to a coordinated effort with Voltage Power to control and protect pedestrian and automobile traffic along the Niagara Parkway. A safety and rescue plan was also put in place to protect the public, workers, and OPG employees.
When working on top of 130-foot towers, or on gantry towers rising 300 feet above the river, there are no second chances.
Thanks to thorough preparation and planning, every linesperson, painter, and scaffolder demonstrated the highest level of safety awareness to get the job done.
The newly refurbished towers are now continuing to safely and reliably deliver the clean power generated by the Beck II GS to Ontario’s electricity grid. The 16-unit facility is capable of producing up to 1,600 megawatts of electricity, enough to power about 1.5 million homes.
The entire Beck generating complex, which includes Sir Adam Beck I and II GS as well as the Sir Adam Beck Pump GS, produces about 12,300 gigawatt-hours of energy each year – about 40% of OPG’s hydroelectric production, or about 9% of Ontario’s energy needs.
These stations will continue to play a major role in the future to support electrification, fight climate change, and propel Ontario’s economy forward.
