NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

Bruce Reactors' Wait to Restart Extended

LCG, June 13, 2003--Two nuclear reactors in Ontario, Bruce A units 3 and 4, are expected to start later than was recently expected, based on the need to meet regulatory requirements, according to the partnership operating the plants.

The Bruce Power Limited Partnership was formed last year to purchase British Energy's 82.4 per cent stake in the reactors. The restart, says the partnership, will likely be by June 30 for Unit 4, and July 30 for Unit 3. The deal with British Energy specified that the price paid for the units would decrease with the duration of any delays before renewed operation. The partners, each of which owns a 31.6 per cent stake, are Cameco, TransCanada, and BPC Generation Infrastructure Trust, which is under the Ontario Municipal Employees Retirement System. Prior to the purchase deal, Cameco already owned a 15 per cent stake in Bruce Power, which deals in uranium.
