  1. Institute of Electrical and Electronics Engineers Jill Egbert Senior Manager PG&E Smart Energy Web

  2. Introduction • Pacific Gas and Electric Company (“PG&E”) is the franchised Utility serving Northern and Central California; • Approximately 5.2M Electric customers and 4.2M Gas customers; • Customers are well educated and passionate about environmental issues • PG&E has transportation programs that encourage the use of electricity, L/CNG and Hydrogen

  3. PG&E’s Electric Drive Demonstrations • Actively evaluating Electric Drive opportunities both for “Greening” our own fleet and to promote a larger consumer market opportunity • First utility to demonstrate V2G in April; Repeated demonstration at Google in June • Chair EPRI Infrastructure Working Council • Focus on developing infrastructure standards for PHEVs April 2007: PG&E demonstrates Vehicle supplying power to the Grid Ford F550 Trouble Truck Phoenix SUT Ford Escape V2G Demonstration at Google Campus June 2007 Dodge Sprinter Van

  4. PG&E Challenges • Customers expect their utility to be an actively green, innovative, leader while maintaining low rates and bills • Increasing energy demands with peak electric load growing faster than off-peak load • Current and future state-mandated Renewable Portfolio Standards • 20% derived from renewable resources by 2010 and legislation currently in the California Assembly to increase to 33% by 2020 • Carbon Caps under AB32 and other Legislation • Trend will be towards increasingly cleaner generation sources

  5. Wind Generation: Difficult to Predict How does a Utility plan for resources with this profile? 700 Each Day is a different color. 600 • Day 29 500 • Day 9 400 • Day 5 • Day 26 Megawatts 300 • Average 200 100 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 -100 Hour Wind profile pattern in April 2007

  6. Electricity as a Fuel • Fuel diversity reduces impact from volatility and promotes stability • Significant portion of existing generation fuel mix is currently CO2 free • Approximately 56% of PG&E’s energy portfolio is CO2 free • Recent and ongoing legislation promotes cleaner generation mix over time • RPS legislation enacted in 21 states • Low fuel cost and minimal additional infrastructure required • Time of Use rates for EV/PHEV charging can create economic incentives • Preferential rates for off-peak consumption • Large night-time “off peak” usage can reduce overall system average rates • Improves utilization rates for existing generation portfolio • Projected future renewables tend to be an off-peak energy resource

  10. Industry Challenges - Standardization • Standardization required for plug-in vehicles to achieve critical mass penetration • Automakers must be able to produce one vehicle for all utility territories • Vehicle owners need to be able to travel across utility lines and be billed properly (cellular phone model) • Standardization to include charging, metering, and communications domains • Required charging infrastructure: Connectors and levels • Accurate and discrete measurement of energy delivered • Communications protocol standards: Wireless and wired • Relevant global standards bodies • Institute of Electrical and Electronics Engineers (IEEE) • Electric Power Research Institute – Infrastructure Working Council (EPRI - IWC) • International Standards Organization (ISO) • American National Standards Organization (ANSI) • SAE International (SAE) • European Telecommunications Standards Institute (ETSI)

  11. PG&E Corporation is committed to being an environmental leader by providing safe, economical, and reliable products and services in a responsible and environmentally sensitive manner. THANK YOU!
