The Keystone Pipeline System is an oil pipeline system in Canada and the United States, commissioned in 2010 and now owned solely by TC Energy. It runs from the Western Canadian Sedimentary Basin in Alberta to refineries in Illinois and Texas, and also to oil tank farms and an oil pipeline distribution center in Cushing, Oklahoma. The pipeline became well known when a planned fourth phase, Keystone XL, attracted opposition from environmentalists, becoming a symbol of the battle over climate change and fossil fuels. In 2015 Keystone XL was temporarily delayed by then-President Barack Obama. On January 24, 2017, President Donald Trump took action intended to permit the pipeline's completion. In 2013, the first two phases had the capacity to deliver up to 590,000 barrels per day of oil into the Midwest refineries. Phase III has capacity to deliver up to 700,000 barrels per day to the Texas refineries.
