The $900 million LNG receipt terminal is capable of processing up to 1.5 billion cubic feet per day (Bcf/d) of natural gas. At the peak of its four-year construction, the project employed more than 1,000 workers.

"Cameron LNG represents the most visible of our recent Gulf Coast natural gas infrastructure investments, which also include pipelines, natural gas storage facilities and a natural gas utility," Felsinger said. "With this new terminal, and our existing Energia Costa Azul terminal on the West Coast, we are the only company able to provide access to the North American market from either the Pacific or Atlantic basins."

"This project would not have been possible without the help of many businesses, elected leaders, regulators and local residents," Felsinger said. "We look forward to working with the state of Louisiana on future energy projects that address the state's energy needs and those of our nation."

"Sempra Energy's decision to invest $900 million and establish Cameron LNG in Southwest Louisiana is building upon this region's terrific economic momentum," said Gov. Bobby Jindal. "We have recently announced several major projects in Southwest Louisiana including Shaw Modular Solutions, the Northrop Grumman KC-10 contract and now, the official start up of Cameron LNG. These announcements reflect the comprehensive reforms we have made to Louisiana's business climate, which have enabled our state to continue successfully attracting companies during this time of national economic downturn."

Cameron LNG's first cargoes of imported natural gas arrived in June and the project began commercial operations on July 30.

About 65 percent of the combined 2.5 Bcf/d capacity of the Energia Costa Azul and Cameron LNG terminals is contracted. Cameron LNG has a 20-year contract with Eni S.p.A., an Italian energy company, and a flexible agreement with RasGas to purchase up to 50 LNG cargoes through Dec. 31, 2010. Energia Costa Azul's capacity is contracted under agreements with Shell, Gazprom and Sempra LNG Marketing.
