as National Model • 2001 – Began purchasing light duty hybrid electric vehicles• 2002 – King County purchased 237 hybrid electric buses• 2006 – King County joined the Chicago Climate Exchange• 2006 – King County mandated that by 2012 50% of fuel consumed must

come from renewable resources or efficiencies• 140 light duty hybrid electric vehicles and 75 flex-fuel vehicles• Largest consumer of bio-diesel in the State of Washington – about 2 million

gallons used in 2006• 2007 -- Will take delivery of the first 3 heavy duty hybrid electric trucks• Made public commitment to purchase 400 plug-in vehicles • September, 2007 will host one of the largest clean vehicle conference


King County’s Hybrid Electric Program

Why an HEV Program?• Started in 2001 in support of King County’s

commitment to the environment• No infrastructure costs• Higher mileage range• Lower maintenance cost• Anticipated higher re-sale price• High user acceptance• Potential for lower life-cycle cost• Reduced dependency on foreign fuel• Reduced greenhouse gas emission


King County’s Hybrid Electric ProgramBenefits:• Reduces fossil fuel consumption• Reduces fuel cost up to 70%• Reduces carbon emission up to 70%• Eliminates fuel loss from idling• Lowers maintenance costs due to extended maintenance

interval• Significant contributor to meeting King County Energy Plan

and CCX target.• Potential for reducing vehicle lifecycle cost• Enhances public image of King County• Establishes King County as a leader and a first responder in

addressing the issue of global warming


King County’s Hybrid Electric Program

King County’s Experience:• HEVs are reliable - very few incidences of malfunction• Increase fuel efficiency up to 70% over similar conventional

size of vehicle• High user satisfaction rating of 4.6 out of maximum rating

of 5• Projected HEV salvage value is 20% of the purchase price

compared to the actual salvage value of 12% received on similar conventional vehicle

• HEV is the vehicle of choice of KC users• Purchase of HEV is more attractive when the price of fuel

is high


King County’s Hybrid Electric ProgramKing County Experience: cont’d• Older model Prius not used for 3-4 days may experience difficulty

in starting due to drain on ignition starting battery• Projected Maintenance cost for Prius is 13% lower than similar

size conventional vehicle• Projected lifecycle maintenance cost of the Escape is 25% lower

than similar size conventional vehicle• User expressed higher level of satisfaction with the Ford Escape

than the Toyota Prius primarily due to more conventional and user friendly configuration

• Toyota allows only dealerships to perform warranty work on the Prius

• Ford allows King County to perform warranty work on the Ford Escape

• Shorter turnaround time experience performing warranty work on the Escape than the Prius


King County’s Best Practices

• Provide ASE Certification training for all technicians

• Provide Manufacturer Technician Training on the safety features of working around the hybrid electric high voltage system

• Purchase and have readily available rescue equipment as recommended by manufacturers in the event of an accident

• Extend HEV preventive maintenance service intervals thereby reducing maintenance costs

• Provide driver orientation on the features and operation of hybrid electric vehicles

The Supply of HEVs

• Acquire HEVs from both state and county contracts• Availability of hybrid electric vehicles is limited to certain

makes and models – supply is adequate• Unleaded fuel is readily available • Parts and supplies are readily available, accessible and

at competitive prices • Vendor support is excellent• Vendor training is available


Conclusions

Summary: KC hybrid electric Program• King County began implementing its hybrid electric

program in 2001• HEV supports the County’s environmental corporate goal • Life cycle analysis on HEVs indicates that this program

does not cost the county more over the lifecycle of the vehicle

• HEVs are good for the environment• Overall performance of HEVs has met manufacturers’

claims and the County’s expectations


Conclusions

Successes:• HEVs have generated strong user support• HEVs’ introduction in the fleet was seamless • HEVs’ performance is reliable• HEVs use less fuel • HEVs emit up to 70% less CO2 • HEV Program positioned King County as a national

leader and first adopter of climate change mitigation technology

• HEV use has made King County a repository of information in the use of hybrid electric technology


Conclusions

Challenges:• HEV availability is limited to certain makes and models• HEV prices are higher than conventional vehicles• HEVs from Toyota result in higher cost and longer turnaround

time from ferrying vehicles to dealerships for warranty repairs• HEV technology is new, therefore there exists a lack of

historical data• HEV training for technicians is not always available on site• HEV’s high voltage technology may pose a danger in case of

accident• Convince Toyota to allow in-house warranty repair


Conclusions

Next Steps:• Increase the number and diversity of hybrid electric fleet• Expand hybrid electric fleet to include heavy duty trucks • Seek grant funding to offset the incremental higher cost

of heavy-duty hybrid electric vehicles• Use the Responsible Purchasing Network Guide to

develop a strategic plan for mitigating global warming • Use the Responsible Purchasing Network as a resource

to select fuels that minimize greenhouse gas emission• Publish King County’s success with HEVs
