Southern Company, Tampa Electric Company and EOG Resources, Inc., have committed to a total of 245 million cubic feet per day (MMcf/d) of capacity on the pipeline that will bring natural gas from east Texas and north Louisiana to U.S. markets needing additional natural gas supply.

With previously announced commitments from Florida Power & Light Company and Progress Energy Florida, SESH's total subscribed capacity is now 945 MMcf/d. SESH will continue to solicit shipper interest in the remaining capacity and the market need for a future expansion.

SESH filed an application with the Federal Energy Regulatory Commission (FERC) on Dec. 18, 2006, seeking approval to construct, own and operate the pipeline.

The Southeast Supply Header is a joint venture between subsidiaries of CenterPoint Energy, Inc. and Spectra Energy. The 270-mile, 36-inch and 42-inch diameter pipeline will extend from the Perryville Hub in northeast Louisiana to the Gulfstream Natural Gas System, which is 50 percent owned by an affiliate of Spectra Energy. Along the route, SESH will access several major pipelines serving the eastern United States and have access to several storage facilities.
