Less than three months after entering service, Southeast Supply Header LLC (SESH) is conducting a nonbinding open season for a proposed expansion along its existing 274-mile route.

The pipeline is a venture of affiliates of Spectra Energy Corp. and CenterPoint Energy Inc. and currently extends from CenterPoint’s Perryville Hub near Delhi, LA, to the Gulfstream Natural Gas System LLC interconnection near Coden, AL.

“The SESH pipeline is strategically positioned to provide flexible and economic transportation solutions to meet the energy needs of the southeast U.S.,” said SESH’s David Shammo. “The SESH pipeline provides these markets with access to a diverse array of onshore supply basins and multiple interconnections with major north-south pipelines, and with high-deliverability storage facilities.”

SESH will accept nonbinding nominations for service from any existing or proposed receipt points to any existing or proposed delivery points on its system. The specific scope of the expansion will be finalized following the results of the open season. The target in-service date would be as early as mid-2011.

Nominations will be accepted through 5 p.m. EST Jan. 16. For information, contact Randy Riha at rjriha@spectraenergy.com, or (713) 627-4746. Information also is available at www.southeastsupplyheader.com.

SESH entered service in September (see Daily GPI, Sept. 10). The 36- and 42-inch diameter pipeline spans three Gulf Coast states and includes laterals in Mississippi and Alabama, as well as three mainline compressor stations in Mississippi and Alabama. Customers signed up for capacity on SESH include Florida Power and Light, Progress Energy, Southern Co., Tampa Electric and EOG Resources.

Evidence of growing demand for natural gas in Florida and the Southeast, particularly for power generation, is provided by Florida Gas Transmission’s recent application at the Federal Energy Regulatory Commission to build 483.2 miles of pipeline to meet expanding demand in the Sunshine State (see Daily GPI, Nov. 18).
