1 Smart Grid Vision

2 Vision Statement PG&E s vision for the Smart Grid: Smart Grid will leverage advanced communications and control technology to transform the operation of our electric network, from generation to the customer premise, in order to give customers cleaner, more reliable and more flexible energy services. Generation Transmission Substation Distribution Customer 2

3 Smart Grid Drivers Regulatory & Legal Drivers Cyber Security Environmental Concerns Renewable / Clean Power Reporting Requirements Safety Customer Drivers Information Needs Flexible Energy Prices Rate Pressures Reliability Renewable / Clean Power Safety Technological Advances (e.g. Appliances) Business & Financial Drivers Aging Assets Aging Workforce Growth / Workload IT / Communication Advances Rate / Rising Cost Pressures Safety Skilled Workforce Technological Advances (e.g. Utility Equipment) 3

4 Smart Grid Energy Policy Federal Policy (2007 EISA, Title XIII) It is the policy of the United States to support the modernization of the Nations electricity transmission and system to maintain a reliable and secure electricity infrastructure State Policy (SB 1438, Pending) The bill would require that the Smart Grid improve overall efficiency, reliability and cost-effectiveness of electrical system operations, planning and maintenance Regulatory Policy CPUC CEC Smart Grid OIR to comply with 2007 EISA examining several Smart Gird-related, utility applications. Smart Grid workshops examining potential demand-side management benefits 4

5 PG&E s Smart Grid framework Smart Grid is a layering of technologies Business applications Computing / information technology Applications and integrated business processes that create business and customer value Computing power and information storage infrastructure to support modeling, control, analysis, web presentment, and commercial transactions Advanced communications infrastructure Enables transfer of critical information through advanced data networks Energy infrastructure Physical infrastructure that distributes energy 5

6 Smart Grid Plan of Record The proposed Plan of Record is intended to: Put a stake in the ground for the smart grid functions to be developed in the next four years Make the plan for Smart Grid more concrete The level of development of functions in the Plan of Record will be driven by Customer demand, policy goals, and available funding 6
