Help is on the way for crashing propane prices.

The Mariner East 2 pipeline, called a game-changer at the recent Marcellus-Utica Midstream Conference in Pittsburgh by Amol Wayangakar, principal and founder of Enkon Energy Advisors, will ultimately increase the Marcus Hook terminal’s export capacity by 275,000 barrels per day (bbl/d). Sunoco says the pipeline is on schedule to go online in second-quarter 2018.

Local opposition may delay Mariner 2 until the third quarter, says En*Vantage Inc., but the effect will be the same: an anxious market will wonder if propane will be available in sufficient quantities for winter 2018-2019. Result: upward pressure on prices.
