Public Sector Fleet EV Procurement Examples: A Case Study of Three All-Electric Vehicle Procurements Conducted by the U.S. Navy, City of New Bedford, and City of Seattle
6/6/2017
The deployment of EVs helps fleets to reduce air pollution from vehicle emissions and lower operating costs associated with maintenance and fueling. However, EV procurement by fleets has been limited by the higher up-front purchase costs and lack of availability of EVs compared to their gasoline counterparts, as well as the availability of charging infrastructure. Despite the existing barriers, many state and local public fleets have successfully integrated EVs to their fleets, and have used innovative procurement strategies to reduce the acquisition costs of EVs. This case study explores EV procurements conducted by the U.S. Navy, the City of New Bedford in Massachusetts, and the City of Seattle in Washington State—examples of public fleet procurements that captured financial incentives to reduce the vehicles’ upfront cost.

King County Metro Battery Electric Bus Demonstration: Preliminary Project Results
5/22/2017
The U.S. Federal Transit Administration (FTA) funds a variety of research projects that support the commercialization of zero-emission bus technology. To evaluate projects funded through these programs, FTA has enlisted the help of the National Renewable Energy Laboratory (NREL) to conduct third-party evaluations of the technologies deployed under the FTA programs. NREL works with the selected agencies to evaluate the performance of the zero-emission buses compared to baseline conventional buses in similar service. The evaluation effort will advance the knowledge base of zero-emission technologies in transit bus applications and provide 'lessons learned' to aid other fleets in incrementally introducing next generation zero-emission buses into their operations. This report provides preliminary results from a fleet of 3 BEBs operated by King County Metro in Seattle, Washington.

Implementing Workplace Charging within Federal Agencies
4/19/2017
This case study, prepared for the U.S. Department of Energy Vehicle Technologies Office, draws from available information and lessons learned from federal agencies that have piloted plug-in electric vehicle (PEV) workplace charging programs. It can be challenging for organizations to involve all the key stakeholders needed to develop a charging program, but engaging them at an early stage can simplify the process of setting an adequate plan for the workplace. Key stakeholders may include workplace charging managers, facilities managers, parking managers, employee PEV drivers, legal counsel, employee benefits managers, and union representatives.
Multiple PEV charging stations are available on the GSA schedule. Agencies will need to select the charging station type and design that is most appropriate for each specific worksite - Level 1, Level 2, or DC Fast Charging. In addition, the GSA Blanket Purchase Agreement (BPA) can help reduce upfront costs, which will help keep the reimbursement fees within the threshold of what employees are willing to pay.

Regional Charging Infrastructure for Plug-In Electric Vehicles: A Case Study of Massachusetts
1/6/2017
Given the complex issues associated with plug-in electric vehicle (PEV) charging and options in deploying charging infrastructure, there is interest in exploring scenarios of future charging infrastructure deployment to provide insight and guidance to national and regional stakeholders. The complexity and cost of PEV charging infrastructure pose challenges to decision makers, including individuals, communities, and companies considering infrastructure installations. The value of PEVs to consumers and fleet operators can be increased with well-planned and cost-effective deployment of charging infrastructure. This will increase the number of miles driven electrically and accelerate PEV market penetration, increasing the shared value of charging networks to an expanding consumer base. Given these complexities and challenges, the objective of the present study is to provide additional insight into the role of charging infrastructure in accelerating PEV market growth. To that end, existing studies on PEV infrastructure are summarized in a literature review. Next, an analysis of current markets is conducted with a focus on correlations between PEV adoption and public charging availability. A forward-looking case study is then conducted focused on supporting 300,000 PEVs by 2025 in Massachusetts. The report concludes with a discussion of potential methodology for estimating economic impacts of PEV infrastructure growth.

Clean Cities 2015 Annual Metrics Report
12/28/2016
The U.S. Department of Energy's (DOE's) Clean Cities program advances the nation's economic, environmental, and energy security by supporting local actions to cut petroleum use and greenhouse gas (GHG) emissions in transportation. A national network of nearly 100 Clean Cities coalitions, whose territory covers 80% of the U.S. population, brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction (IR) measures, fuel economy improvements, and new transportation technologies as they emerge. Each year, DOE asks Clean Cities coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Progress reports and information are submitted online as a function of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators report a range of information that characterizes the membership, funding, projects, and activities of their coalitions. They also document activities in their region related to the development of refueling/charging infrastructure, sales of alternative fuels; deployment of alternative fuel vehicles (AFVs), plug-in electric vehicles (PEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs); idle reduction initiatives; fuel economy improvement activities; and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use and GHG emission reduction impacts, which are summarized in this report.

Field Evaluation of Medium-Duty Plug-in Electric Delivery Trucks
12/16/2016
This report focuses on medium-duty electric delivery vehicles operated by Frito-Lay North America (FLNA) at its Federal Way, Washington, distribution center. The 100% electric drive system is an alternative to conventional diesel delivery trucks and reduces both energy consumption and carbon dioxide (CO2) emissions. The vehicles' drive cycles and operation are analyzed and compared to demonstrate the importance of matching specific electric vehicle (EV) technologies to the appropriate operational duty cycle. The results of this analysis show that the Smith Newton EVs demonstrated a 68% reduction in energy consumption over the data reporting period compared to the conventional diesel vehicles, as well as a 46.4% reduction in CO2 equivalent emissions based on the local energy generation source. In addition to characterizing the in-use performance of the EVs compared to the conventional diesels, detailed facility load data were collected at the main building power feed as well as from each of the 10 EV chargers to better understand the broader implications associated with commercial EV deployment. These facility loads were incorporated into several modeling scenarios to demonstrate the potential benefits of integrating onsite renewables.

National Economic Value Assessment of Plug-in Electric Vehicles: Volume I
12/1/2016
The adoption of plug-in electric vehicles (PEVs) can reduce household fuel expenditures by substituting electricity for gasoline while reducing greenhouse gas emissions and petroleum imports. A scenario approach is employed to provide insights into the long-term economic value of increased PEV market growth across the United States. The analytic methods estimate fundamental costs and benefits associated with an economic allocation of PEVs across households based upon household driving patterns, projected vehicle cost and performance attributes, and simulations of a future electricity grid. To explore the full technological potential of PEVs and resulting demands on the electricity grid, very high PEV market growth projections from previous studies are relied upon to develop multiple future scenarios.
