ENOVA’s Case for Fleet Electrification

There were more than 16 million public and private fleet vehicles on the road in the US in 2009. The concentration of buying power represents a significant opportunity to assist the early development of the electric drive vehicle industry.

4

o Today, 94 % of the delivered energy that powers the U.S. transportation system is petroleum based

o Petroleum accounts for 40% of the US Energy needs o Transportation accounts for 70% of the oil used in the

US at 14 Mio barrels per day and 55% worldwide o Today the US is hostage to a global Oil Market that is

likely to become increasingly more volatile. In July of 2008 we hit $147 per barrel triggering the most severe recession since WW2.

o The most significant risk to global economic recovery is increased economic activity is propelling oil prices back toward these 2008 levels

o Ave from 2005-2010, the US spent about 5% of its GDP or >900 billion on petroleum based fuels.

Advantages of fleet electrification

The electrification of our fleets has clear advantages: o Electricity represents a diverse, domestic, stable and scalable energy

source whose inputs are almost free of oil. o High Penetration of grid enabled Electric and Hybrid Fleets will minimize

the dependence of oil of the US, strengthen our economy, improve national security and provide more flexibility in our foreign policies.

o Simultaneously this change will allow to reduce emission of GHG.

The ENOVA case for Fleet electrification

Fleets tend to possess a handful of important characteristics that make them more likely to take on the potential risks of electric drive ownership in anticipation of reaping financial benefits down the road.

Fleets have: o Total Cost of Ownership Approach to Acquisition o Route Predictability & lower Range → right size battery, ↓ waste o High Vehicle Utilization Rates o Use of Centralized Parking, less dependent on public charging o Are likely to already have the heavy-duty electric grid connections

needed for rapid charging o Increased Importance of Maint. & Service Costs (longer life/miles) o Access to Lower Electricity Rates o Access to Alternative Business Models such as leasing etc. o Corporate Sustainability Initiatives & access to government funding

6

Challenges of Fleet Electrification

Fleet operators also face challenges. Some of the basic cost and technology hurdles for individual consumers will also be problematic for fleets, but fleets are typically better equipped to deal with them.

Fleet electrification can come with its own set of unique challenges that can be addressed through a combination of careful planning and selection of components and public policy support:

o Technology Costs, mostly battery cost o Capital Expense vs. Operating Expense o Questions regarding Residual Value of the Battery o Fleet Infrastructure Issues (cost of chargers ↓ v.s. charge time) o Utility Impact of Dense Charge Networks o Market Perception, need for confidence that technology/vehicle

can deliver

Social cost of lack of electrification

The total cost to public health and society of the existing motor vehicle fleet (fleet average) is more than $10 billion in 2010 for California alone. An American Lung Association’s/ TIAX LLC study from 2008 (Road to a cleaner future) finds that if California implemented converting the automobile fleet from gasoline to completely zero emission technologies would: o Save $142 billion in the 2010 – 2030 timeframe, or $96 billion more than relying on the cleanest gasoline technologies and o Avoid at least $2.2 billion per year in health costs from exposure to directly emitted fine particulate matter (PM 2.5) o Avoid total of 6,000 premature deaths could be avoided by 2030 o Avoid >260 cases of chronic bronchitis, >7,000 asthma attacks o Avoid >18,000 cases of upper & lower respiratory symptoms each year
