Line 5 transports up to 540,000 barrels per day (bpd) of light crude oil, light synthetic crude oil, and natural gas liquids (NGLs), which are refined into propane. These products heat homes and businesses, fuel vehicles, and power industry in the state of Michigan.
As of June 2016, Line 5 supplies 65 percent of propane demand in the Upper Peninsula, and 55 percent of Michigan’s statewide propane needs.
The light and synthetic crude oil transported on Line 5 meets increasing demand from refineries in Michigan and Ohio for Bakken light crude. About 30 percent of that light crude stays in the region, where it's processed and used to power industry, and turned into the gas, diesel and jet fuel that keep our economy running.
Taking Line 5 out of service would result in the loss of about 56,000 barrels per day of available crude supply, and 15,000 barrels per day of available propane, from the Michigan economy. That's the energy equivalent of:
Line 5 does not carry, and has never carried, heavy crude oil.
