Enbridge Pipeline Reversal Earns BP's Ire, Suncor's Praise

Enbridge Inc.’s decision to implement and then scrap new rules governing Canada’s biggest export pipeline system sent crude prices on a record roller coaster move this week, earning the pipeline operator both friends and enemies. BP Plc filed a complaint this week with Canada’s National Energy Board saying Enbridge used an “unreasonable exercise of discretion” when it announced and then, 11 days later, canceled new rules governing the amount of oil that shippers were allowed to send through its Mainline system. Heavy Western Canadian Select crude prices surged by a record $12.20 a barrel relative to U.S. benchmark West Texas Intermediate futures Monday after Enbridge scrapped the rule, which was designed to stop shippers from claiming more space than they needed on the pipeline.
