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
► will enable the introduction of demand-response rates for residential and small business customers

Customers► Receive usage information to better understand and manage their bills, and be able to participate in future
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
Smartmeter Program Has A Range Of Benefits
► Reduced operating costs
► Reduced peak loads when customers shift to non-peak energy use and when they conserve (demand response)
► Lower procurement costs resulting from reduced peak load and enhanced load modeling
► Improved customer satisfaction stemming from enhanced customer service capability
► Improved billing efficiency
► Improved outage management
► Reduced energy theft
PG&E
► Supports the CPUC’s price-responsive tariff requirements

90% of costs
► The SmartMeter program has a positive business case: Projected benefits exceed projected costs over a 20 year program life
► Operational efficiencies (including meter reading savings) cover 90% of program costs
► Demand response benefits (i.e. procurement cost savings) cover approximately 10% of program costs and promise to provide additional benefits in excess of costs
* 20 year Present Value of Revenue Requirement

An “Activated” Meter Has Several Characteristics
► Installed: the endpoint equipment (meter for electric, module for gas) has been placed on customer premises
► Readable: the SmartMeter system communicates with the endpoint equipment
► Billable: the billing system can use interval data collected through SmartMeter to bill the customer
► Part of a virtual meter reader route string: the meter reader can be re-deployed when the virtual route string is removed from the manual meter reading workload
Meters are activated in batches, by virtual route string
Once a meter is activated, actual meter reading benefits begin to accrue

Activated Meters Lifecycle
Updates to billing system
Customer account changed to “SM enabled”
Meters become searched in SM system
Billing system performs validation
Electric meters take longer to search in than gas meters
Customer account changes to “SM read”
Last manual meter read
Visual inspection to QA SM installs
Customer billed on manually collected anchor reads
Service plan transition from manual meter reading route to SM route
Consists of manual meter reading routes with zero meters (i.e. completed routes)
One completed route for each serial
Captured in reports
Meters are activated
Network installed with serial diversification
Endpoints installed with serial diversification
Committed to the CPUC for benefits associated with activated meters, by writing monthly checks utilizing SM balancing account ($1.77 each electric meter, $1.04 each gas meter)

BenefitsRealizations
Customer accounts on a SM route are part of a pool of meters eligible for activation
A “complete” route is an manual meter reading route with zero meters
Can create a completed route with limited number of meters (Excludables, UTCs, other meters out of scope) via either “closed routes” benefits functionality or manual re-routing

Benefits Realization For Meter Reading
► Meter reading benefits account for the bulk for program benefits - 53% of SmartMeter operational (i.e. non demand response) benefits; 46% of total benefits
► Benefits are booked in a balancing account as soon as the meter is “activated” – PG&E cuts a check to the balancing account
► Meter reading benefits can only be realized once a meters on a virtual route string are activated or transferred to a different route
► Virtual route string = routes with different serials
► Meters are activated only after they are: installed, readable, billed, part of a completed virtual route string
► PG&E fine tunes installation activity to complete virtual route strings as soon as possible
