A Sempra Energy affiliate has launched a nonbinding open season to gauge interest in natural gas storage capacity that would feed export terminals on the Gulf Coast. 

Sempra LNG launched the open season Tuesday for its proposed Hackberry Gas Storage project in Hackberry, LA. The facility would be on a 160-acre parcel and would include four storage caverns and associated infrastructure.

The project would support the feed gas supply needs of Sempra’s 15 million metric tons/year (mmty) Cameron liquefied natural gas (LNG) export terminal, also located in Hackberry, and the 13.5 mmty Port Arthur LNG export terminal proposed for Southeast Texas.

The company began the pre-filing process with the Federal Energy Regulatory Commission in July. When completed, the project is expected to provide 26 Bcf of storage capacity. It would interconnect with the Cameron Interstate Pipeline (CIP) and tap into the Port Arthur Pipeline — Louisiana Connect too.

The 2.35 Bcf/d CIP links Cameron LNG with five interstate lines, while the proposed 2 Bcf/d Port Arthur Pipeline would provide feed gas for the Port Arthur LNG project, which is expected to be sanctioned next year. 

The open season is scheduled to close at 4 p.m. CT on Sept. 15. Interested parties should contact rtomaski@sempraglobal.com. More information is available on the company website
