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.

Clean Cities Alternative Fuel Price Report, January 2017
2/27/2017
The Clean Cities Alternative Fuel Price Report for January 2017 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities coordinators and stakeholders between January 1, 2017 and January 15, 2017, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.
Table 2 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has increased 10 cents from $2.22 to $2.32; diesel increased 10 cents from $2.48 to $2.58; CNG price increased 5 cents from $2.06 to $2.11; ethanol (E85) increased 11 cents from $1.93 to $2.04; propane increased 12 cents from $2.68 to $2.80; and biodiesel (B20) has increased 11 cents from $2.46 to 2.57.
According to Table 3, CNG is $.21 less than gasoline on an energy-equivalent basis, while E85 is $0.33 more than gasoline on an energy-equivalent basis.

Preliminary Assessment of Spatial Competition in the Market for E85: Presentation Supplement
2/10/2017
Anecdotal evidence suggests retail E85 prices may track retail gasoline prices rather than wholesale costs. This indicates E85 prices may be higher than they would be if priced on a cost basis hence limiting adoption by some price-sensitive consumers. Using publicly available and proprietary E85 and regular gasoline price data, we examine pricing behavior in the market for E85. Specifically, we assess the extent to which local retail competition in E85 markets decreases E85 retail prices. Results of econometric analysis suggest that higher levels of retail competition (measured in terms of station density) are associated with lower E85 prices at the pump. While more precise causal estimates may be produced from more comprehensive data, this study is the first to our knowledge that estimates the spatial competition dimension of E85 pricing behavior by firms. This technical report elaborates on a related presentation.

On-Road Validation of a Simplified Model for Estimating Real-World Fuel Economy
1/23/2017
On-road fuel economy is known to vary significantly between individual trips in real-world driving conditions. This work introduces a methodology for rapidly simulating a specific vehicle's fuel economy over the wide range of real-world conditions experienced across the country. On-road test data collected using a highly instrumented vehicle is used to refine and validate this modeling approach. Model accuracy relative to on-road data collection is relevant to the estimation of 'off-cycle credits' that compensate for real-world fuel economy benefits that are not observed during certification testing on a chassis dynamometer.

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.

Transforming the Nation’s Electricity System: the Second Installment of the Quadrennial Energy Review
1/6/2017
On January 6, 2017, the Quadrennial Energy Review (QER) Task Force released the second installment of the Quadrennial Energy Review report titled “Transforming the Nation’s Electricity System.” The second installment (QER 1.2) finds the electricity system is a critical and essential national asset, and it is a strategic imperative to protect and enhance the value of the system through modernization and transformation. QER 1.2 analyzes trends and issues confronting the Nation’s electricity sector out to 2040, examining the entire electricity system from generation to end use, and within the context of three overarching national goals: (1) enhance economic competitiveness; (2) promote environmental responsibility; and (3) provide for the Nation’s security.
The report, which provides 76 recommendations that enable sector modernization and transformation, provides the building blocks for longer-term, planned changes and activities undertaken in conjunction with state and local governments, policymakers, industry, and other stakeholders.
