It’s the birth of a brand new pipeline expansion project. Several weeks ago Williams pre-filed with the Federal Energy Regulatory Commission (FERC) to make certain upgrades (all of them in Pennsylvania) to its mighty Transco Pipeline. The upgrades include replacing smaller pipeline with larger pipeline in some areas, adding “looping” in other areas, and upgrading four compressor stations. The changes will flow an extra 582 million cubic feet per day (MMcf/d) of Marcellus gas from northeast and southwest PA to “growing demand centers along the Atlantic Seaboard.” Williams is holding two (of four) open houses next week to discuss the project. Below are details about the project and a copy of Williams’ FERC pre-filing application.
