Bruce A is a 4 x 750-MW CANDU nuclear plant commissioned in the 1970s that was shut down in 1997/98. Bruce Power
leased the Bruce plant in 2001 and decided to restart initially two of the Bruce A units (Units 3 and 4) to take advantage of
opportunities to sell electrical energy within the competitive Ontario market. In October 2005, Bruce Power announced a
long-term agreement to restart Units 1 and 2 so that the units can operate for an additional 25 years.
Restarting the four units will boost Bruce Power’s output to more than 6,200 MW, making it the source of about 25
percent of Ontario’s electricity on a typical day.
Following the restart, the company’s eight units will supply the annual
power needs of more than four million homes.
Hatch predecessor company Acres is a member of the Acres–Sargent & Lundy and E.S. Fox Ltd Joint Venture, known as
ASLF, that is providing engineering and construction services to upgrade the existing fire protection systems and install a
new station secondary control area. The joint venture is working as an integrated team with Bruce Power in its $4.25-
billion investment program, part of which is the restart of Units 1 and 2.
The first unit is expected to return to service in 2011.
ASLF previously acted as the “Main” contractor for the restart of Units 3 and 4 for which ASLF received the prestigious
2004 Schreyer Award from Canadian Consulting Engineer magazine and the Project-of-the-Year Award from Power
