A Single Pipeline's Taking U.S. Gas on a Rollercoaster Ride

  • Updates on Energy Transfer’s Rover line are moving the market
  • Project would unleash Marcellus supply on Midwest markets

Some of this year’s biggest gyrations in U.S. natural gas prices can be chalked up to a single pipeline.

Energy Transfer Partners LP’s $4.2 billion Rover line, scheduled to begin partial service in July, will be one of the biggest links from the Marcellus and Utica shale basins in Pennsylvania, West Virginia and Ohio -- America’s most prolific gas production region -- to the Midwest and Canada. Gas futures surged to a 14-week high on May 10 after a regulatory setbackBloomberg Terminal prompted speculation that the project would be delayed, keeping supplies from reaching those markets.
