Introducing Alternate Fuel Vehicles Into Your Fleet Dave Meisel Director – Transportation Services Pacific Gas & Electric Company October 19, 2010

About PG&E Who we are Gas & electric utility 20,000 employees Service area stretches over 70,000 sq. miles 15 million customers served $42.7B in assets as of December 31, 2009, and revenues of approximately $13.4B Generation PG&E produces more than 4,000 megawatts of electricity through hydroelectric, fossil & renewable generating facilities Diablo Canyon Nuclear Power Plant produces over 2,000 megawatts of electricity Transmission and distribution More than 139,000 circuit miles of electric lines More than 45,800 miles of natural gas pipelines

PG&E’s Green Supply Chain Program is built on tight collaboration with suppliers to:  Adopt more environmentally sustainable business practices across the Supply Chain  Reduce the adverse environmental impact of PG&E’s purchasing decisions  Electrification of fleet  Electrification of worksite The leading utility in the United States Delighted Customers Operational Excellence Transformation We act with integrity and communicate honestly and openly We are passionate about meeting our customers’ needs and delivering for our shareholders We are accountable for all of our own actions: these include safety, protecting the environment, and supporting our communities We work together as a team and are committed to excellence and innovation We respect each other and celebrate our diversity OUR VISION OUR GOALS OUR STRATEGIES OUR VALUES Energized Employees Rewarded Shareholders Environmental Leadership PG&E’s Vision & Values

Thoughts & Challenges What we believe in: Being Green, being Strategic and being Diverse Our sustainability commitment is a winning strategy A green fleet mix – one size does not fit all The challenge: Develop a green supply chain program with an embedded green fleet strategy Build effective utility-supplier partnerships - a true win-win

PG&E’s Green Fleet Strong leadership commitment to green the fleet Nearly 12,000 assets Operate the largest alternative fueled and high efficiency vehicle utility fleet in the nation, with more than 2,600 vehicles –Natural gas (CNG or LNG) 1,100 –Bio-Diesel (B-20) 900 –Electric (on- and off-road) 112 –Hybrid (HEV and PHEV) 490

Actively involved in the development, demonstration and application of natural gas and electric-drive technologies Believe no one fuel or technology is the single answer to our fuel dependency and greenhouse gas issues. Looking at a blended technology portfolio where each application is matched with the appropriate technology that best meets the application needs - especially with the changing technology landscape. PG&E’s Green Fleet: A Techno Mix Natural Gas Vehicles, Hybrids, Plug-In Hybrids, Electric Vehicles, High Efficiency Technology, Fuel Cell Vehicles, E-PTO’s

Why worry about transportation emissions? US GHG Emissions Estimates by Sector, 2008 –Transportation is responsible for 27.1% of US GHG emissions Remains direct combustion and petroleum-based, contributing 32% of total CO2 emissions from fossil fuel combustion –MHD and HHD contribute nearly half of vehicle emissions VMT reductions and alternative propulsion are not the only avenues worth exploring Regulations largely ignore idling emissions Source: 2010 U.S. Greenhouse Gas Inventory Report Transportation, 27.1

Why electric vehicles? Energy independence Gas: Single source and largely importedElectricity: Diverse sources and abundant in the U.S.

12 Why electric vehicles? Savings - Fuel Combustion engine Electric motor 20% efficiency 90% efficiency *Gas equivalent >100 (PHEV) MPG <$1 $/gallon*

13 Why electric vehicles? Savings - Maintenance Internal combustion engine system Electric motor system ~1,400 parts~200 parts *

Projected Electric Vehicle Growth Average (532) Low (219) HEV Historical Cumulative PG&E Service Territory PEV Market Adoption Scenarios High (845) Thousands of EVs * Shifted 10 years forward

Technology Choices “There are no silver bullets, only silver buckshot.” PG&E will be looking at a blended technology portfolio where each application is matched with the appropriate technology that best meets the application needs - especially with the changing technology landscape. As of yet, no single fuel or technology seems to provide the answer to the diverse business needs of the transportation sector of the utility industry.

Hybrids and Plug-In Hybrids Fuel savings opportunities Very duty-cycle dependant PG&E has low mileage, but high PTO usage One size (or type) of hybrid does not fit all Looking at “unbundled” hybrid systems –Highest “value proposition” hybrid elements –PTO usage savings –Cab conditioning –Auxiliary lighting Plug-in hybrids allow displacement of diesel with clean electricity

High Efficiency Technologies Battery powered Power-Take-Off (PTO) Called E-PTO –Powers boom and tool circuit –Climate Control –Vehicle auxiliaries Charging by plugging in and/or by engine alternator power Offers “silent” work location opportunities Substantial reduction in fuel usage

The Challenges Employee Challenges –Familiarity - With the operation and nuances of the equipment –Flexibility - Rotation of untrained operators into unfamiliar equipment –Availability of qualified technicians (internal and external) Equipment Challenges –Price / Return on investment (some are better than others) –Price and volume are not always connected (sometimes additional regulations and increasing sophisticated systems drive price up, not down –Performance varies significantly based on make, model and manufacturer even among like technologies –Parts availability –Technical issues Fiber optics and transceivers Batteries – what is the right size and chemical composition Charging system – what is the best way to charge the batteries Range limitations Raising the technical skills of present employees

The Challenges Infrastructure Challenges –Consistency of equipment (plugs, plug locations, speed of charge, etc) –Infrastructure investment (limited or non-existent on-site & public charging stations) Regulatory Challenges –Technology is moving so fast that some of the regulators are behind, especially on incentives. Sorting through the marketing material –Understand the technology –Understand the full cost / benefit analysis –Electric vehicle research center

Alternate Fuel Rollout Plan Development of comprehensive rollout plan –Technology identification –Matching technology to current business needs –“Engineering” vehicles –Identifying potential placement locations – “rifle approach” –Constructing “flexible, expandable” infrastructure –Provide a systematic rollout to clients and garages –Provide over-all communications to all stakeholders on project –Continue to seek outside funding for vehicles and infrastructure
