Williams Atlantic Sunrise Project to Begin Partial Service on Sept 1

Atlantic Sunrise Pipeline – click for larger version

An important piece of Williams’ $3 billion Atlantic Sunrise Pipeline project, meant to flow Marcellus gas to new markets in the Mid-Atlantic and southeast, is about to go online in the next few days. You read that right. Most of the coverage here on MDN with respect to the Atlantic Sunrise project has been about the most controversial part of the project–183 miles of new “greenfield” (brand new) pipeline construction that will happen in Pennsylvania–a project referred to as the Central Penn Line. Small groups of antis in places like Lebanon and Lancaster counties have vigorously opposed the new pipeline portion of the project in their communities. However, upgrades to several compressor stations and fixes to the existing Transco pipeline as it runs through states like Maryland and Virginia are also needed in order to make Transco bi-directional–able to continue flowing gas from the Gulf to the northeast, but now, also able to reverse and flow gas from the Marcellus/Utica in the other direction. Although the greenfield portion of the project has not yet begun (should in the next few weeks), the “brownfield” or tweaks to the existing pipeline/compressor stations has been underway, since February, and is now ready. The Federal Energy Regulatory Commission (FERC) has just granted Williams permission to bring the new tweaks online, which will allow Transco to reverse and flow an extra 400 million cubic feet per day (MMcf/d) of natural gas from Lancaster County, PA all the way to Choctaw County, Alabama…
