EIA: Marcellus Takeaway Capacity Rising, More Coming This Winter

Two projects scheduled to begin initial service by the end of September could increase natural gas takeaway capacity in the Marcellus Shale by a combined 0.5 Bcf/d, according to the U.S. Energy Information Administration (EIA).

The agency added that another five projects could collectively add another 1.99 Bcf/d of takeaway capacity from the Marcellus during the upcoming winter months.

That won't quite match the 40% or 2.1 Bcf/d increase in Marcellus production in the first half of this year over the first half of 2012. Total dry gas production in the Marcellus was measured at 9.3 Bcf/d in June 2013.

In its latest Natural Gas Weekly Update, the EIA said projects by Tennessee Gas Pipeline (TGP) and Columbia Gas Transmission Corp. (TCO) "would be the first of several projects increasing natural gas takeaway capacity from Marcellus planned for completion this winter."

Last week, TGP asked FERC for authorization to put a pipe expansion in northern Pennsylvania into service by Monday, and for compression station modifications to be placed into service by Nov. 1 (see Shale Daily,Sept. 17). The pipeline -- also known as Loop 313, part of TGP's MPP project -- is a 7.9-mile, 30-inch diameter looping segment with 0.23 Bcf/d capacity.

On Sept. 6, TCO requested the Federal Energy Regulatory Commission's permission to begin service on the Warren County Extension pipeline on Sept. 30. The 2.5-mile, 0.22 Bcf/d pipeline would connect the TCO pipeline with Dominion Virginia Power's Warren County Power Station, a 1,329 MW gas-fired power plant near Front Royal, VA.

According to the EIA, TCO's project also includes upgrades to compressor stations along its main line, which carries gas east from the Marcellus Shale in West Virginia. TCO, a NiSource Inc. subsidiary, also plans to replace its interconnect with Williams' Transcontinental Gas Pipe Line (Transco) near Rockville, MD.

The EIA cited five projects that collectively would increase takeaway capacity even further when they come online this winter:

  • Dominion Transmission Inc.'s (DTI) Sabinsville-to-Morrisville Project, a 3.56-mile, 24-inch diameter pipeline, adding 0.09 Bcf/d of capacity to an interconnect with TGP, in service by November (see Shale DailyMarch 12);
  • DTI's Tioga Area Expansion Project, a 15-mile, 24-inch diameter pipeline adding 0.26 Bcf/d of capacity to an interconnect with Transco at Leidy, PA, and a new interconnect with Spectra Energy Corp.'s Texas Eastern Transmission (TETCO) in Greene County, PA, also in service by November;
  • TETCO's plans to begin service on a 0.78 Bcf/d expansion for a portion of pipeline connecting Linden, NJ, to Manhattan, NY;
  • Transco's Northeast Supply Link expansion, adding 0.24 Bcf/d of capacity to its existing pipeline network, in service by the end of the year (see Shale DailyJuly 15); and
  • TGP's Northeast Upgrade Project, which would expand TGP's existing 24-inch diameter 300 Line by building five, 30-inch diameter pipeline loops and modifying four existing compressor stations, adding 0.62 Bcf/d of capacity (see Shale DailyApril 3).

 The EIA will release its next Natural Gas Weekly Update on Thursday.
