All copyright and trademark rights reserved. Status of San Onofre Nuclear Generating Station (SONGS) • The SONGS units have experienced some accelerated wear in the steam generator tubes, resulting in the units being temporarily taken out of service. • For a scenario in which both SONGS units remain off- line, the CAISO, SDG&E and SCE will face a unique, difficult summer situation. • Return-to-Service of one or both units during summer is not expected. • Must be prepared for the possibility that neither SONGS unit will be available during summer, or that they operate at reduced capacity. 2 Statewide Outlook • Projected peak demand of 46,352 MW • Projected 48,091MW of instate generationavailable (w/o SONGS) • 2,296MW of statewide demand response available • Statewide water runoff forecasts well below average for all basins, impacting hydroelectricity capacity Could run 1,137 MW less than years with normal snow – pack • Import levels under high peak demand is projected to vary from 8,600 MW to 11,400 MW, totaling about ¼of demand 3 4 Contingency Planning • The loss of SONGS negatively impacts the Southern California electric power system Risk of load shedding increases – Operational studies ongoing between CAISO, SCE, and SDG&E to quantify and – plan for these risks • Sunrise is in service Increases SDG&E import capability – Reduces loading on natural gas system – • Huntington Beach Units 3 & 4 returned to service Adds resource in Orange County – Mitigation of voltage collapse in Orange County – Assists import capability to San Diego – • SCE Barre-Ellis Upgrade Project completed 5 San Diego Resources to Serve Load Under Different Operating Scenarios without San Onofre Units Current With Huntington With Sunrise StatusBeach 3 & 4Powerlink 4882 MW (90/10) 4438 MW (50/50) 6 Note: does not include demand response High Risk Days • Historically, the peak electric demand in San Diego occurs in late August to early September. However , heat spells can roll through any time during the – summer months • San Diego normally gets 2-3 three heat spells each summer, each lasting about 3-4 days. So calls for conservation could be made 6 –12 days due to – weather variability. • Operations issues, such as the loss of a major plant or transmission line, or statewide issues, could trigger the need for conservation at any time 7 Reduce Your Use Day Rewards • Launching to all Residential customers on June 1, 2012 • Proposal to add small business customers (<20kW) for additional response: 8 Conservation and Communications Conservation outreach • Energy conservation messages in statewide and local Flex Alert campaigns Customer communications campaign • Coordinated communications throughout all programs • Tiered messaging strategy  Base summer preparedness  Non-critical need for conservation  Critical need for conservation • A variety of paid and non-paid channels will be used including ethnic media and community-based organizations 9 SDG&E is Disaster and Fire Ready • SDG&E maintains 24x7 Emergency Operations Center • To date, the utility has invested about $200 million to replace more than 1,650 transmission wood poles with steel. Over the next five years, SDG&E plans to invest more than $900 million to harden all transmission lines currently on wood poles in the Fire Threat Zone. • Aggressive Award-Winning Vegetation Management -maintains clearance for more than 400,000 trees, nearly 100,000 of these trees are located in the Highest Fire Risk Area (HRFA). • Unveiled Mobile Field Command Trailers and Satellite Phone Booths 10 SDG&E is Disaster and Fire Ready • SDG&E owns and operates the third-largest weather network in the United States, monitoring fire risks such as wind speed. • A Utility Wildfire Prevention Teamwill join our crews during high fire risk times of the year. • Industrial Fire Brigade with new flammable liquid firefighting trailers will coordinate with first responders at SDG&E facilities to improve fire risk reduction capabilities. • Please visit our emergency preparedness web pages sdge.com/safety/outages/outage- weather-conditions 11
