Natural gas spot prices at Sumas on the Canada-Washington border averaged $161.33/mmBtu on March 1, the highest daily price Natural Gas Intelligence recorded anywhere in the US in at least five years. The spike followed a polar vortex, unusually cold weather, and reduced flows after an October 2018 pipeline explosion on Enbridge's BC Pipeline.
The spike was a regional, short-lived supply and weather shock that has since faded, so its effect on national gas and feed-ingredient costs is limited. It does show how fragile Western Canadian and Pacific Northwest supply can be during cold snaps.
