HOUSTON, June 20, 2006 – Kinder Morgan Energy Partners, L.P. (NYSE: KMP) and Sempra Pipelines & Storage, a unit of Sempra Energy (NYSE: SRE), today announced the start of a binding open season to solicit support to extend the Rockies Express Pipeline (REX) east from its currently proposed terminus at the Clarington Hub in Monroe County, Ohio, to Oakford, Pa.  The approximately 100-mile pipeline extension would also pass through Waynesburg, Pa., and is designed to provide up to 1.8 billion cubic feet per day (Bcf/d) of firm transportation capacity.  The extension would feature additional compression and interconnects to several major interstate natural gas pipeline systems serving the northeastern United States.

        “We are excited about the possibility of extending the Rockies Express Pipeline, which would provide consumers in several high-demand markets along the East Coast significantly enhanced access to reliable, long-lived domestic sources of natural gas,” said Scott Parker, president of KMP’s Natural Gas Pipelines group.  “All aspects of the Rockies Express project remain on schedule,” he added.

        The open season, which began today, ends Friday, July 14, 2006, at 5 p.m. MDT.  Subject to shipper support and regulatory approval, the extension is expected to begin service January 1, 2010. Information related to the open season can be obtained by contacting Jeff Rawls at Kinder Morgan (303) 914-4903 or Ryan O’Neal at Sempra Pipelines & Storage (619) 696-4585.   

        The 1,663-mile, $4.4 billion REX project, which is designed to transport natural gas from producing areas in Colorado and Wyoming, is the largest pipeline built in the United States in more than 20 years.  The initial 136-mile, 36-inch segment that runs from the Meeker Hub in Rio Blanco County, Colo., to the Wamsutter Hub in Sweetwater County, Wyo., was approved for service in February 2006.  Construction on the 192-mile stretch from the Wamsutter Hub to the Cheyenne Hub in Weld County, Colo., will begin this summer, with service expected to begin in January 2007.  In May 2006, KMP and Sempra Pipelines & Storage filed an application with the Federal Energy Regulatory Commission (FERC) to construct the REX-West portion of the pipeline from the Cheyenne Hub to Audrain County, Mo.  The 713-mile segment is projected to begin service in January 2008.  The application pre-filing process for REX-East, which runs from Audrain County to the Clarington Hub, was initiated with FERC in June 2006.  Pending regulatory and environmental approvals, the 622-mile segment is expected to begin service in June 2009.     

        Additional information related to the binding open season, including a map and detailed procedures, is available on the REX web page at www.kindermorgan.com.
