  2. The Heat Storm Was an Extraordinary Event Throughout the State (1) • PG&E highest temperatures in 34 years • Peak load 13% higher than last year • SCE one in ten year event • Peak load 3.6% higher than last year • SDG&E one in 25 year event • Peak load 11% higher than last year • ISO Peak: 50,270 MW – 11% higher than 2005. Reserves were at 5%.

  3. The Heat Storm Was an Extraordinary Event Throughout the State (2) • Storm affected electricity grid during weeks of July 17 and July 24 • 138 deaths attributed to the heat storm • The electric distribution infrastructure took a beating • Transformers failed • PG&E 1200 • SCE 1375 • SDG&E 170 • Customers lost distribution service, most for short times • PG&E 1.3 million • SCE 1.1 million • SDG&E 45,000

  4. ISO, Generators, Utilities, Firefighters, and Customers Rose to the Occasion • ISO operated the grid efficiently and flexibly • Generators kept the power plants operating • Utility crews replaced blown transformers • Firefighters protected the grid • Customers responded to Flex Your Power calls

  5. PUC Action Plan Underway Now • Increase Targeted Energy Efficiency • Increase Demand Response • New Local Generation

  6. Increase Targeted Energy Efficiency • PG&E and SCE now soliciting additional third party programs using 2006-2008 program budgets. • Looking for innovative, targeted energy efficiency programs focusing on high-demand areas.

  7. Increase Demand Response • Increased Air Conditioner Cycling • Demand Response Programs For This Summer • Demand Response Programs For 2007 and Beyond

  8. Increase Air Conditioner Cycling • Peevey Assigned Commissioner Ruling August 15 • Directs Edison to bring 300 MW more online by Summer 2007 • Directs PG&E, SDG&E to report on opportunities

  9. Increased Demand Response Programs for this Summer • E-4009: No advice letter. Initiated by Energy Division.  Adopts a new triggering mechanism for the Demand Reserves Partnership program for the purpose of increasing demand response for the remainder of this summer. • E-4011: SDG&E AL 1811-E.  Approves modifications to SDG&E’s C&I 20/20 Program for the purpose of increasing more demand response for the remainder of this summer. • E-4012: PG&E AL 2870-E.  Approves a modification to the Demand Bidding Program (PG&E/SCE/SDG&E) for the purpose of increasing demand response for the remainder of this summer. • E-4018: PG&E AL 2880-E.  Approves re-opening PG&E’s Interruptible tariff for remainder of 2006 but not 2007.

  10. Demand Response Programs for Next Summer and Beyond • Peevey Assigned Commissioner Ruling August 9 • Directed new demand response proposals August 30th. • Received proposals for new and expanded existing programs. • Commission decision in November.

  11. New Local Generation • Five New Generators for Edison, and Requests by PG&E and SDG&E • Peakers • Dispatchable • Supports local distribution system

  12. Increased Use of Cooling Centers (1) • PG&E • 31 Cooling Centers PG&E separately refers approximately 300 customers who self-identify as “heat sensitive” to Rotating Outages Cooling Stations. PG&E is also expanding its efforts to inform its customers about how to take care of themselves in the event of extreme heat.

  13. Increased Use of Cooling Centers (2) • SCE • 38 Cooling Centers • SCE has outreach program for targeted populations through informational fliers, public service announcements, targeted mailings, targeted events, local newspapers, and through established partnerships with businesses and other community-based organizations. • In response to lessons learned during the last heat wave, SCE contractors have implemented grass roots door-to-door outreach within farm-worker communities, senior housing, and low-income housing developments to inform vulnerable populations of the availability of Cool Center sites.

  14. Increased Use of Cooling Centers (3) • SDG&E • San Diego County has 150 Cooling Centers • SDG&E provides partial support to San Diego County’s Cool Zones Program through its CARE program. • Outreach for the Cool Zones program is a collaboration between SDG&E and the County of San Diego. A kick-off event was held which received local media attention, and the County also promotes Cool Zones through its own methods.

  15. Taking Stock and Planning for the Future • Is our forecasting good enough? • Are we out of the woods for this summer? • What does next summer look like? • What about the future?

  16. Temperature Trends in the Last 100 yrs Summer
