TC Energy declared a force majeure on Keystone, which carries crude from Alberta to refineries in the U.S. Midwest. Repairs are underway, but the company said there is currently no timeline for restoration of full service.
The incident took place on Sunday.
“Repairs are being undertaken and we are working to restore full service as soon as possible” TC Energy said in a statement.
In a shipper notice seen by Reuters, the company said the pump station facility had been isolated and would remain isolated until the power impact is resolved.
