Highlights ► The PG&E Smart. Meter program: ► will deploy a system for automated Highlights ► The PG&E Smart. Meter 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. Mass deployment is targeted for September 2007. 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 as early as summer, 2007 5 Note: Information in this presentation represents the best efforts of PG&E’s ESP and IT teams to identify future system output.

Implications for ESPs ► ESPs will not be able to read Smart. Meter gas Implications for ESPs ► ESPs will not be able to read Smart. Meter gas or electric meters ► Some meters are initially excluded from Smart. Meter deployment: ► Current electric DA interval meters (PG&E and 3 rd party) will not be impacted until 2009 ► DA metering rules will not change for electric accounts. Electric ESPs will still have the option to replace a Smart. Meter electric meter with a 3 rd party owned meter for accounts >50 k. W ► Account switching will occur on the bill date, not the meter read date ► EDI file content changes for both gas & electric (814, 867 and 810) ► The largest implication for ESPs at this point and the reason for today’s webcast 9 Note: Information in this presentation represents the best efforts of PG&E’s ESP and IT teams to identify future system output.

I. Smart. Meter Data - EDI 814 (ACK) (Gas & Electric) Changes ► When I. Smart. Meter Data - EDI 814 (ACK) (Gas & Electric) Changes ► When a Smart. Meter gas or electric meter is installed, PG&E: ► Assigns a new SA ID ► New SA IDs will be assigned when a Smart. Meter enabled meter is installed ► The DA XREF will remain the same ► ► ► Identifies the interval size the meter is registering (i. e. 00000015, 00000060, 000001440) Assigns a new rate name - “H” (e. g. , HE 1, HG 1) Snapshot reports will be updated with new SA IDs and “H” rate schedule names ► ► Snapshot reports are provided to ESPs twice a month Switch date will occur on the bill date, not the meter read date 11 Note: Information in this presentation represents the best efforts of PG&E’s ESP and IT teams to identify future system output.
