SAN DIEGO, Oct. 1, 2008 – Sempra Energy (NYSE: SRE) today announced the completion of its acquisition of Mobile, Ala.-based EnergySouth Inc. for $510 million in cash. 

        The acquisition was accomplished via a merger of a Sempra Energy subsidiary and EnergySouth.  Sempra Energy’s Sempra Pipelines & Storage unit will operate the EnergySouth business as part of Sempra Pipelines & Storage’s existing operations.

        The acquisition, which was announced July 28, gives Sempra Energy a majority ownership in two large, high-cycle underground natural gas storage facilities that, when fully developed, will have capacity of 57 billion cubic feet of natural gas serving the nation’s fastest-growing natural gas markets. 
 
        “We are pleased with the closing of this transaction and the positive support from shareholders and regulators,” said Donald E. Felsinger, chairman and chief executive officer of Sempra Energy.  “The Gulf Coast is of growing importance as a critical energy hub for North America and these new assets allow us to quickly expand our natural gas infrastructure business in the region. “

        As part of the transaction, Sempra Energy also acquired Mobile Gas Service Corp., an Alabama natural gas distribution utility owned by EnergySouth.  Mobile Gas serves approximately 93,000 customers in southwest Alabama, a region that stands to benefit from strong economic development within its service territory.  James M. Fine has been named president of Mobile Gas.  He previously served as the company’s vice president of operations.

        A substantial majority of EnergySouth shareholders approved the transaction yesterday.  They will receive $61.50 per share.  The transaction also has received all necessary regulatory approvals, including federal antitrust clearance under the Hart-Scott-Rodino Act.
 
        Sempra Pipelines & Storage develops, builds and operates natural gas pipelines and storage facilities in Latin America and the United States.  The company and its affiliates operate and/or own more than 1,200 miles of pipelines and are developing an additional 800 miles to help meet North America’s growing demand for energy.   It also manages natural gas and electricity distribution in Argentina, Chile, Mexico and Peru.
