Maintenance Outage at Genesee 3


EDMONTON, Alberta – Capital Power Corporation (TSX: CPX) (Capital Power) has notified the Alberta Electric System Operator (AESO) that the Genesee 3 unit is expected to be offline for an estimated five weeks due to unplanned maintenance requirements. The outage duration estimate is preliminary and based on an initial review of information.

On November 11, 2011, the Genesee 3 plant, a 495 gross megawatt (MW) joint venture with TransAlta Corporation (247.5 net MW ownership interest), experienced an unplanned outage that resulted in damage to turbine/generator bearings. As the plant operator, Capital Power is working diligently to return the unit to service by mid-December, 2011. The root cause of the outage is under investigation, and a turbine bearing inspection is ongoing at this time.

As a result of the event, Capital Power’s fourth quarter production from its Alberta coal fleet is expected to be reduced by approximately 180 gigawatt hours. Additional generation from Capital Power’s 243 MW Clover Bar Energy Centre peaking facility, is expected to materially offset the lost production from the Genesee 3 facility.
