Suncor operations cease at base plant after 'process upset' knocks out power

Suncor Energy Inc. says operations have ceased at its oilsands base plant near Fort McMurray, Alta., after a temporary power loss Wednesday afternoon.

Company spokesperson Erin Rees would only describe the cause of the power loss as a ``process upset'' but says power was restored as of Wednesday night.

Rees says she cannot provide more detail because it's a ``day to day operational issue.''

She says the incident does not impact the safety of the company's employees or contractors.

Suncor is currently focused on a safe return to operations, Rees says.

She says during that return to operations, there is potential for additional flaring at the plant.
