10. 10 Start-Up of Costa Azul LNG Terminal Start-up testing of 1 Bcf/d Costa Azul LNG terminal occurred in May 2008 Terminal received two cargos for start-up supplies Terminal had to complete performance test by running at 1 Bcf/d and peak 1.3 Bcf/d capacity Costa Azul supplies delivered to SoCalGas/SDG&E system through new Otay Mesa receipt point and at Blythe through new North Baja pipeline Costa Azul terminal declared operational on May 15, 2008 Terminal expandable to 2.5 Bcf/d

11. 11 Costa Azul Start Up Monitoring Results LNG supplies just another source of gas supply – like we currently receive from California, Southwest, Rocky Mountains or Canada Utilities didn’t expect any customer equipment performance issues with introduction of LNG supplies, but conducted LNG Roll-Out Plan during Costa Azul start-up to assess how commercial/industrial end-use equipment responded to changes in gas quality Costa Azul Start Up Monitoring Project Results – Validated Prior Studies and Testing – SDG&E and SDCAPCD monitored and collected information for key end use equipment: Electric Generation and Co-generation Gas Engines Boilers Residential Equipment (Monitoring ) – No significant issues were encountered; equipment performance exceeded expectations in certain cases

12. 12 Future Expectations for Costa Azul Expectations of future deliveries from Costa Azul remain uncertain Costa Azul capacity split 500 MMcfd each to Sempra LNG and Shell – However, Shell recently completed a “subleasing” deal with Gazprom for a quarter of the capacity – Sempra’s long-term supplies from Tangguh project in Indonesia – Shell has available capacity now - long-term supplies from Sakhalin project in Russia – No cargoes are anticipated until early next year because of languishing prices here Current spot market not favorable to near-term Costa Azul deliveries – 2008 US LNG imports down significantly from 2007 – trend could change with additional LNG production due online in 2009. Some cargos to Costa Azul will be needed regardless of price to maintain terminal – One maintenance cargo has already been received by the terminal in August 2009

14. 14 California LNG Projects Clearwater LNG Project No current timetable for issuing draft environmental impact report for the project The federal licensing clock has apparently stopped as the U.S. Coast Guard had sent the applicant a list of 396 questions Woodside Project In January 2009, Woodside announced that it was shelving plans due to “changed energy market conditions.” Port Esperanza Project Yet to file formal Deepwater Port Application so project future uncertain.

21. 21 While Gas Prices Have Fluctuated; SoCalGas’ Transportation Costs Have Been Flat Transport costs are the Volumetric & Customer Charge. Core GN10 @ 100,000 th /year and Noncore GTF/I3-D @ 1.5MMth/year. Core Gas Cost is SCG’s core procurement rate and CA Border Index is Natural Gas Intelligence Index

22. 22 Where are Gas Futures Prices Going ?

23. 23 Natural gas wellhead price is projected to rise from low levels experienced during 2008-2009 recession 2008 dollars per thousand cubic feet ProjectionsHistory AEO2010 reference case Updated AEO2009 reference case Source: Annual Energy Outlook 2010

24. 24 High levels of gas price volatility will likely continue. Shale gas drives growth in natural gas production and reduces reliance on imported gas. Higher demand expected for U.S. gas fired electric generation. Natural gas prices projected to rise with economic recovery. North American Natural Gas Market

25. 25 What Can You Do to Manage Energy Costs? Take advantage of energy efficiency programs. Call your Account Executive for technical support. Go to socalgas.com/business for support tools. If you transport your own gas, talk to your gas supplier to discuss supply and pricing strategies. Look for ways to conserve and be more energy efficient.
