In the earnings conference call, Guy Jarvis, Enbridge’s president of liquids and pipelines said that with the current opposition to pipelines, it’s easier to make incremental changes to the existing network to get oil flowing to U.S. ports. "All of these involve relatively small, low cost, bolt-on projects that can be staged in increments as required to meet shipper needs," said Jarvis. The company also said in the call that it expects Keystone XL to be in operation in 2019 and for one of the West Coast pipelines to be operating in 2020. That would be either Northern Gateway or Kinder Morgan’s Trans Mountain pipeline expansion. It’s notable that it didn’t express any confidence Gateway would be the pipeline in operation, even though it is further ahead in the regulatory process and Kinder Morgan is facing a lot of opposition of its own.
