Project Details

  • Owner: Enbridge[1]
  • Capacity: 180,000 barrels per day[1]
  • Length: 1,588 miles (2,556 km)[2]
  • Diameter: 20-inches[2]
  • Status: Operating[1]
  • Start Year: 2010[1]


The Southern Lights light hydrocarbon pipeline consists of 474 miles of 16-inch to 20-inch pipelines for transporting diluents to Alberta, which is blended with oil sands prior to export to the US. It is twinned with the Southern Access Crude Oil Pipeline, which runs in the reverse direction, from Edmonton, Alberta, in Canada to Manhattan, Illinois. It began operating in 2010.[1]

Expansion Projects

Reversal and Conversion Expansion Project

According to data from the U.S. Energy Information Administration (EIA), Enbridge has announced that the pipeline will be reversed and converted. The pipeline will be reversed to flow southeast from Alberta, Canada, to Illinois. Pipeline will also be converted to carry crude instead of diluent. The project is expected to be complete in 2023 and will result in an additional 150,000 barrel per day (bpd) of transport capacity. The project does not involve adding any new miles of pipeline.[3]
