More pipeline capacity out of the glutted Marcellus Shale region could be on the way depending upon the success of pipeline open seasons announced last week (see related story).

Gulf South Pipeline Co. LP announced a plan to serve South Louisiana demand from the Marcellus as well as other basins, and separately, ANR Pipeline Co. launched two open seasons, offering capacity from the Marcellus to the Gulf Coast and Midwest.

ANR is holding a binding open season through Oct. 22 for its Lebanon Lateral 2014 Reversal Project. The pipeline is holding a separate nonbinding open season through Oct. 23 for its Glen Karn 2015 Project. The projects would provide Marcellus gas producers with access to the pipeline’s markets in the Midwest and Gulf Coast.

Lebanon Lateral would provide capacity from a new receipt point with Dominion Transmission Inc. (DTI) on the Lebanon Lateral at Lebanon, OH. ANR would modify facilities on its system between Glen Karn and its Southeast Mainline near its Sulphur Springs Compressor Station and on its joint ownership capacity in the Lebanon Lateral to allow the flow of gas from DTI at the Lebanon receipt point to points on ANR’s system, the pipeline said.

A foundation shipper has subscribed for 100,000 Dth/d of capacity as part of the original project for a 10-year term. The foundation shipper capacity will not be pro-rated as a result of current open season. Any subsequent party that submits a qualifying bid may be pro-rated with other shippers for the remaining capacity being made available, ANR said.

The targeted in-service date of the Lebanon Lateral project is the later of March 1, 2014 or the date facility modifications are placed in-service. If modifications are not in-service by March 1, 2014, ANR can provide interim service from the Lebanon receipt point to existing delivery points on the Lebanon Lateral between Lebanon and Glen Karn. ANR said it will consider bids requesting start dates as early as March 1, 2014 to as late as Nov. 1, 2014.

Modifications would include the installation of valves, yard piping, and other ancillary facilities at Lebanon, Glen Karn and Sulphur Springs to permit bi-directional flow on the lateral. ANR is offering to provide firm service for up to 250,000 Dth/d from the Lebanon receipt point to points on its system.

Separately, the Glen Karn project is designed to provide service on ANR’s system from its existing interconnection with Texas Eastern at Glen Karn, OH (the Glen Karn receipt point) to points on its system. The project is being proposed due to the amount of interest ANR has received from parties seeking the ability to deliver gas to ANR from Texas Eastern at Glen Karn by Nov. 1, 2015, the pipeline said.

Nov. 1, 2015 is the targeted in-service date of the Glen Karn project. It is designed to coincide with the targeted in-service date of Texas Eastern Transmission LP’s Uniontown to Gas City Project. ANR is offering to provide firm services for up to 400,000 Dth/d from its interconnection with Texas Eastern at Glen Karn to points on its system.

ANR said it will determine the facilities necessary for the Glen Karn project based on open season results. The facilities could include the installation of compression at or near Glen Karn and/or modifying existing compression at the existing Sulphur Springs Compressor Station and/or other ancillary facilities on ANR’s system between Glen Karn and its mainline near its Sulphur Springs Compressor Station.

Separately, Gulf South is targeting growing industrial demand in the Baton Rouge-New Orleans, LA, region with a potential expansion of its system that would tap shale gas supplies from multiple basins. The project joins another targeting a similar market from rival Spectra Energy Transmission.

The pipeline is holding an open season through Oct. 18. Gulf South is directly connected to shale gas supplies in Louisiana and Texas, along with traditional gas supplies in the Louisiana-Texas Gulf Coast region. Through interconnections with affiliate and third-party pipelines, Gulf South’s customers are able to access gas from Arkansas, Texas, Oklahoma and the Marcellus Shale through Gulf South’ s Perryville Exchange or interconnects at Kosciusko, MS.

Last year, Gulf South launched its Perryville Exchange Service at the Perryville Hub in Louisiana (seeNGI, Feb. 13, 2012) with the intent that, along with a system expansion, it would streamline delivery of gas to power generators in the Southeast (see NGI, July 16, 2012).

In order to serve the growing industrial natural gas markets, Gulf South is proposing an expansion of its system that will connect these supplies to markets in the Baton Rouge to New Orleans River Corridor for service commencing in 2016 and 2017 (the New Orleans River Corridor Expansion Project). The Boardwalk Pipeline Partners LP subsidiary,said it will determine whether to proceed with the project and the size by Dec. 18.
