Suncor Energy reports planned repair schedule for damaged upgrader

Calgary, Alberta (February 22, 2010) — Suncor Energy Inc. announced today that it has completed its assessment and expected schedule to repair portions of an oil sands upgrader (U1) damaged by fire in early February. Repairs are currently underway and the company now expects the upgrader to return to production in early April.

In addition to the investigation into the cause of the fire, Chief Operating Officer Steve Williams has initiated an independent investigation supported by third party experts to review process safety and reliability. The findings from this investigation will be used to benchmark against industry best practices and assist in supporting Suncor’s operational excellence initiatives.

During the repair period, the company’s second upgrader (U2) is expected to continue normal operations. Combined production of synthetic crude oil and bitumen sold directly to markets during this period is targeted at an average of approximately 210,000 barrels per day (bpd) in February and 230,000 bpd in March (these volumes do not include Suncor’s proportionate production share from the Syncrude joint venture). Accordingly, Suncor’s production outlook issued on February 4, 2010 will be impacted and will be updated with the release of the company’s first quarter results on May 4.

Based on the damage assessment and repair schedule, and applicable waiting periods and deductibles, Suncor does not expect insurance to play a significant role in mitigating losses from this incident.
