Energy Transfer anticipates the expansion could make at least 600 million cubic feet per day of firm transportation capacity available, of which 400 million cubic feet per day has already been subscribed under a ten-year contract. Ultimate capacity of the expansion will be based upon producer response.

The company is conducting a binding open season and accepting shipper commitments through March 18. The approximately 180-mile and 42-inch Tiger natural gas pipeline will serve multiple basins, including the Haynesville shale and Bossier shale producing regions in Louisiana and East Texas.

Pending necessary regulatory approvals, the Tiger pipeline is expected to be in service in the first half of 2011 and the expansion is expected to be in service in the second half of 2011.
