The 240,000 dekatherms per day (dth/d) project includes about eight miles of 30" pipeline looping and modifications to four existing compressor stations in Pennsylvania to provide gas transportation from the Marcellus Shale supply area to existing delivery points on the TGP system.

All of the capacity has been subscribed through agreements with Chesapeake Energy Marketing for 140,000dth/d and Southwestern Energy Services for 100,000dth/d.

TGP plans to file a certificate application for the MPP project with the Federal Energy Regulatory Commission in late 2011.

Construction on the pipeline project, which is subject to regulatory approvals, is expected to begin in 2013.
