        SAN DIEGO, June 5, 2007 – Sempra Energy (NYSE: SRE) today announced that Carlos Ruiz Sacristan has joined the company’s board of directors.

        Ruiz, 57, currently is a partner of Proyectos Estrategicos Integrales, a Mexican investment-banking firm.  Ruiz also serves on the board of directors of Southern Copper Corp., a copper producer in Mexico and Peru.

        From 1974 to 1988, Ruiz held positions of increasing responsibility at Banco de Mexico.  His experience also includes service as a director on boards of several financial institutions and other public companies and commissions.
        Ruiz has a bachelor’s degree from Anahuac University in Mexico City and a master’s degree in business administration from Northwestern University in Chicago.
