SAN DIEGO, Oct. 5, 2010 – Sempra Pipelines & Storage, a unit of Sempra Energy (NYSE: SRE), today announced that it has placed in service Cavern 4 at its Bay Gas Storage natural gas storage facility in Alabama.

            Cavern 4 will add 5 billion cubic feet (Bcf) of working gas capacity.  The new cavern is fully subscribed.  

            Construction of Cavern 5 also is underway at the facility.  With a planned in-service date in 2012, Bay Gas Cavern 5 is expected to add another 5 Bcf of working gas capacity, bringing total capacity at the facility to 21.4 Bcf.

            “Bay Gas has been a very productive storage asset providing services to the Florida market and other markets in the Southeast,” said George S. Liparidis, president and chief executive officer of Sempra Pipelines & Storage.  “We are pleased to expand our capacity for serving those markets with the initiation of service at Cavern 4, as our midstream asset development program continues to advance.”

       Located approximately 40 miles north of Mobile in southwest Alabama, Bay Gas Storage operates in a strategically valuable location with exceptional access to the high-demand Florida market and markets across the Southeast, Mid-Atlantic, and Northeast regions.  Bay Gas pipeline interconnects include:  Florida Gas Transmission, Gulf South and Transcontinental Pipeline.
                       
            Expansion activities at Bay Gas follow the successful start-up of Mississippi Hub in August.  Located in Simpson County, Miss., Mississippi Hub is a high-deliverability salt dome natural gas storage facility asset owned and operated by Sempra Pipelines & Storage.

            Sempra Pipelines & Storage and its affiliates currently operate and own 23 Bcf of storage capacity, with plans to develop as much as 75 Bcf by 2015 to help meet North America’s growing demand for natural gas storage.  The company also manages natural gas and electricity distribution in Argentina, Chile, Mexico, Peru and the U.S.

            Sempra Pipelines and Storage is a subsidiary of Sempra Energy, a San Diego-based Fortune 500 energy services holding company.
