Questions have been raised about the newly enlarged Panama Canal’s ability to handle all the LNG shipments U.S. producers are gearing up for. How will the canal’s huge, new third set of locks handle all the traffic? With Corpus Christi, Texas, two other U.S. Gulf Coast terminals expect to join Cheniere Energy Inc.’s Sabine Pass, La., facility loading tankers. Dominion Energy Inc.’s Cove Point, Md., plant on Chesapeake Bay is adding still more, and Kinder Morgan Inc.’s Elba Island, Ga., terminal is on the way.
