Inergy LP unit Inergy Midstream LLC is holding a nonbinding open season through Feb. 15 for firm wheeling service on a proposed extension of its Tres Palacios gas storage facility pipeline header system.

The project would create a new interconnect at the tailgate of Copano Energy LLC's Houston Central gas processing plant in Colorado County, TX.

The project is expected to include approximately 20 miles of lateral piping, additional compression and interconnect facilities. Once complete the Tres Header Project would allow shippers to move gas along 60 miles of header pipe with access to a combination of 10 interstate and intrastate pipelines and the Tres Palacios storage facility. Additionally, shippers would have access to the Tres Palacios Hub point, which is listed on IntercontinentalExchange for natural gas transactions.

Copano's Houston Central Plant currently provides 700MMcf/d of processing capacity and 22,000 b/d of fractionation capacity and is being expanded to handle rich gas from the Eagle Ford Shale play. The Tres Palacios facility will give producers additional options for the sale of residue gas at the tailgate of the Houston Central Plant.

Tres Palacios is about 100 miles southwest of Houston in Matagorda County, TX. The facility includes 38.4 Bcf of working gas capacity with planned expansion to 47.9 Bcf.

The anticipated in-service for the pipeline extension is in summer 2012. For information contact Bruce Page at (281) 453-5306 or Jeff Reavis at (281) 453-5307. Requests for open season packages may be emailed to bpage@inergyservices.com.

Inergy acquired Tres Palacios last fall (see Daily GPI, Oct. 18, 2010).
