Solar Metering and Performance Monitoring Exposition
June 4, 2007

The PG&E SmartMeter program:► will deploy a system for automated meter reading – hourly meter reads for
electric, and daily meter reads for gas
► includes two separate systems: a power line carrier system for electric and a radio frequency system for gas
► involves an upgrade to both gas and electric meters – approximately 10 Million meters will be upgraded
► will be deployed over a five year period. An initial, paced deployment began in Bakersfield in November, 2006. Deployment efforts are scheduled to conclude in late 2011
► will introduce additional capabilities over time, including outage management and remote connect/disconnect (for a subset of electric customers)
► will enable the introduction of demand-response rates for residential and small business customers
3
Customers► Receive usage information to better understand and manage their bills, and be able to
participate in energy efficiency and demand response programs► Experience less inconvenience and intrusion by no longer needing to unlock gates and tie up
dogs for monthly meter reads► Reduction in the causes of delayed, inaccurate and estimated bills► Experience faster outage detection and restoration times► Opportunity to turn service on and off remotely
Overview: Benefits
► Experiences reduced operating costs
► Improved billing efficiency through reduced exceptions processing
► Experiences improved customer satisfaction
► Accomplishes goal of lower procurement costs
► Achieves reduced energy theft
► Provides improved outage management
PG&E
► Supports the CPUC’s price-responsive tariff requirements

Demand Response
Benefits (100%)
► The SmartMeter program has a positive business case: Projected benefits exceed projected costs by 4%► Operational efficiencies (including meter reading savings) account for approximately 86% of benefits► Demand response (i.e. reduction in procurement costs) accounts for about 14% of benefits, and promises
to provide an additional positive return on our investment

Completed Retrofit
The SmartMeter enabled electric meter will look much like standard electromechanical meter, but will include a SmartMeter electric module (i.e. remote communications equipment, or RCE)

RF network is designed for redundancy
► On average, each gas meter will be read by at least 3 data collector units (DCUs)
► The DCU reception range is approximately 1 mile
► A single DCU can handle up to 50,000 meters

Deployment volumes for SmartMeter gas and electric meters will ramp to a peak of over 12,000 meters per day

Support for solar requirements
► Current SmartMeter technology supports net metering only
► A separate measure of generation would require a second meter
► PG&E continues to monitor and evaluate advances in automated metering technologies
► The CPUC asked PG&E to evaluate new technologies on an ongoing basis
► We evaluate against the solar requirement for a separate measure of generation
► Some new technologies provide this capability and we are looking at these carefully
