Energy Transfer Partners  (ETP)  , operator of the  much maligned and controversial Dakota Access pipeline, is expected to save the North Dakota energy industry $540 million in annual shipping costs as it gives state producers cheaper access to refineries. 

The $3.7 billion 1,100 mile pipeline was approved by President Trump in February and will carry 500,000 barrels of oil per day, more than half of the state's overall output.
