Bruce A’s Unit 4 back in operation, marking major milestone for plant

For the first time in two decades, all four units at the Bruce A nuclear plant in Ontario are in operation, following the return to service of Unit 4.

Having all four units at Bruce A in operation is a significant achievement for the Bruce site, said Duncan Hawthorne, Bruce Power President and CEO, in an April 13 statement.

“Through the return to service of Units 1 and 2 last year, combined with investment programs in both Units 3 and 4, we now have all Bruce A units generating low-cost electricity for the first time in two decades and for years to come,” Hawthorne said. “Electricity from Bruce A is important as Ontario moves forward to complete coal phase-out with affordable Bruce Power nuclear.”

Prior to its planned outage, Unit 4 had a record run of over 570 days of continuous operation.

“We are pleased with the strong performance of Units 1 and 2 since they returned to service and Unit 3 has also run safely and reliably following the West Shift Plus program last year,” said Len Clewett, Executive Vice President and Bruce Power’s Chief Nuclear Officer. “With Unit 4 back, Ontario can now count on all four Bruce A units to meet the province’s energy needs, while keeping costs low for our families and businesses.”

Bruce Power operates the world’s largest operating nuclear power facility and is the source of about 25% of Ontario’s electricity. The company’s site in Tiverton, Ontario, is home to eight CANDU reactors with a total capacity of about 6,300 MW. Bruce Power has four reactors in each of Bruce A and Bruce B. Since 2003, all four Bruce A units have been refurbished and returned to service, adding an additional 3,000 MW of power to the provincial electricity grid. Each of the eight units has a net rated output of 750 MW-840 MW.

Formed in 2001, Bruce Power is an all-Canadian partnership among TransCanada, Cameco, Borealis Infrastructure Management (a division of the Ontario Municipal Employees Retirement System) as well as the Power Workers’ Union and Society of Energy Professionals. A majority of Bruce Power’s employees are also owners in the business.
