Cautionary Statement Regarding Forward-Looking Information

This presentation contains forward-looking statements regarding Pacific Gas and Electric Company’s (Utility) anticipated investment in energy-efficiency programs and

expected energy savings related to energy-efficiency programs. These statements are based on current expectations and various assumptions which
management believes are reasonable. These statements and assumptions are necessarily subject to various risks and uncertainties the realization or
resolution of which are outside of management's control. Actual results may differ materially. Factors that could cause actual results to differ materially include:

–

The Utility’s ability to timely recover costs through rates;

–

The outcome of regulatory proceedings, including ratemaking proceedings pending at the CPUC and the FERC;

–

Changes in demand for electricity and natural gas;

–

The adequacy and price of electricity and natural gas supplies, and the ability of the Utility to manage and respond to the volatility of the electricity and

natural gas markets;

–

The effect of weather, storms, earthquakes, fires, floods, disease, other natural disasters, explosions, accidents, mechanical breakdowns, acts of

terrorism, and other events or hazards on the Utility’s facilities and operations, its customers and third parties on which the Utility relies;

–

The general economic climate and population growth or decline in Northern and Central California;

–

The potential impacts of climate change on the Utility’s electricity and natural gas operations;

–

Unanticipated population growth or decline, general economic and financial market conditions, and changes in technology including the development of

alternative energy sources, all of which may affect customer demand for natural gas or electricity;

–

The performance and the occurrence of unplanned outages at the Utility’s Diablo Canyon nuclear generating facilities, or the temporary or permanent

cessation of operations at Diablo Canyon;

–

The ability of the Utility to recognize benefits from its initiatives to improve its business processes and customer service;

–

The ability of the Utility to timely complete its planned capital investment projects;

–

The impact of changes in federal or state laws, or their interpretation, on energy policy and the regulation of utilities and their holding companies;

–

The impact of changing wholesale electric or gas market rules, including the California Independent System Operator’s, or CAISO’s, new rules to

restructure the California wholesale electricity market;

–

How the CPUC administers the conditions imposed on PG&E Corporation when it became the Utility’s holding company;

–

The extent to which PG&E Corporation or the Utility incurs costs in connection with pending litigation that are not recoverable through rates, from third

parties, or through insurance recoveries;

–

The ability of PG&E Corporation and/or the Utility to access capital markets and other sources of credit;

–

The impact of environmental laws and regulations and the costs of compliance and remediation;

–

The effect of municipalization or other forms of bypass; and

–

Other factors discussed in PG&E Corporation's and Pacific Gas and Electric Company’s SEC reports.

Revenue/sales decoupling mechanisms paired with annual attrition

rate adjustment mechanism

Sustained, deep commitment by regulators, state lawmakers,

utilities, other stakeholders to energy efficiency, conservation,
renewables, demand-response

Growing interest and commitment by public to improve

environment and mitigate climate change

General agreement utilities are a key player in delivering energy

efficiency programs/savings to customers

Keys To Energy Efficiency Success in California

PG&E Energy Efficiency History

First programs started in 1976

Combined conservation and EE: $9.3 million^* spend

Saved 2^* MW

Very successful program in the 1990’s

Average annual budget of $120 million^* with upside incentives

Saved 880 MW

Presently

Budget- $975 million^* for 2006-2008

Cost-effective CEE is 1^st in loading order in Integrated Resource Plan

Risk-Reward Mechanism: potential for upside and downside

(retroactive to January 2006)

Energy efficiency must offset 50% of load growth

Savings Goals: 613 MW, 3,063 GWH, 47 MM therms

* Excludes LIEE

Why is California Different?

Very large scale, sustained energy efficiency effort

Highly effective codes and standards programs

Escalating IOU, state effort on solar

Energy Efficiency Savings Past and Future

PG&E’s Budget and Goals for 2006-2008:

Overall budget $975 million

Customer Incentives budget $416 million

PG&E filed goals613 MW, 3,063 GWH, 47 MM therms

MW Savings: Historic & Target

California Title 20 appliance standards

California Title 24 building energy standards

Combined savings for all other states that have passed appliance standards

Federal product standards included in the 2005 federal Energy Policy Act of 2005

Codes & Standards: Peak Demand Reduction

Population forecasted to rise from 37.1 million to

42 million (13%) from 2006 to 2016

Electric usage forecast to rise from 279,886 GHW to

313,397 GWH (12%) over same period

Larger homes in hot valley areas

More, higher-use electric devices/household

State’s peak demand rose to 50,270 MW in 2006 heat

spell – 10.7% increase over 2005 peak

Efficiency remains lowest cost resource
