National Park Service Bus Electrification Study: 2020 Report
2/1/2021
This report summarizes important considerations for implementing battery electric buses (BEBs) in the three national park fleets, detailing information about current buses at each fleet, electric bus demonstration vehicles, and performance evaluations of BEBs in Zion, Bryce, and Yosemite. Results include in-use data collection metrics such as average bus speed, energy usage per trip, and daily distance traveled. Also covered are effects of high heating, ventilation, and air-conditioning system use to both heat and cool the buses, emissions estimations before and after use of electric buses, operating costs, electric vehicle infrastructure, maintenance, and bus driver user experience survey information.

When Might Lower-Income Drivers Benefit from EVs? Quantifying the Economic Equity Implications of EV Adoption
2/1/2021
Plug-in electric vehicles (PEVs) can dramatically reduce local air pollution and carbon emissions, but relatively little analysis has been done on the broader potential economic benefits as the technology matures and costs decline. As governments seek to integrate decarbonization policy with environmental justice goals, it will be critical to ensure equal access to clean technology. This report focuses on the potential benefits of equitable electrification and assesses when PEVs will become affordable more broadly across different households.

Final Technical Report-WestSmart EV: Western Smart Plug-in Electric Vehicle Community Partnership
1/19/2021
The WestSmartEV (WSEV) project has accelerated adoption of electric vehicles (EV) throughout the PacifiCorp/Rocky Mountain Power’s service territory in the intermountain west by developing a large-scale, sustainable EV charging infrastructure network with coordinated EV adoption programs. The project objectives have strategically deployed 79 direct current fast charging to create two primary electric interstate highway corridors along I-15 and I-80. Additionally, it has incentivized installation of Level 2 chargers at workplace locations, incentivized the purchase of EVs, provided all electric solutions for first- and last-mile trips, provided centralized data collection, analysis, modeling, and tool development to inform investment and policy decisions, and developed education outreach materials and conducted workshops across the WSEV region. This report summarizes the WSEV project efforts.

EV Charging and Public/Private Partnerships: RFP Template
1/1/2021
An effective request for proposal (RFP) is often the critical first step towards transportation electrification. This RFP template from Forth Mobility provides essential guidance for cities seeking to expand their electric vehicle (EV) charging infrastructure, especially for projects intended to be owned and operated by a partner vendor at low- or no-cost to the city. The RFP template will assist cities and EV charging infrastructure deployment partners in creating measurable project goals and having a better understanding of what is being asked of them. Further, Forth Mobility has designed the RFP template to support cities in collaborating with the private sector not only to expand EV infrastructure, but also to strengthen public-private partnerships through flexibility and goal fulfillment. Specifically, the RFP template offers cities and private-sector partners guidance on site ownership, payment models, and potential site locations.

Electric Vehicle Charging Infrastructure Trends from the Alternative Fueling Station Locator: Second Quarter 2020
1/1/2021
The U.S. Department of Energy’s Alternative Fueling Station Locator contains information on public and private non-residential alternative fueling stations in the United States and Canada and currently tracks ethanol (E85), biodiesel, compressed natural gas, electric vehicle (EV) charging, hydrogen, liquefied natural gas, and propane stations. Of these fuels, EV charging continues to experience rapidly changing technology and growing infrastructure. This report provides a snapshot of the state of EV charging infrastructure in the United States in the second calendar quarter of 2020. Using data from the Station Locator, this report breaks down the growth of public and private charging infrastructure by charging level, network, and location. Additionally, this report measures the current state of charging infrastructure compared with the amount projected to meet charging demand by 2030. This information is intended to help transportation planners, policymakers, researchers, infrastructure developers, and others understand the rapidly changing landscape for EV charging.

Electrification Futures Study: Scenarios of Power System Evolution and Infrastructure Development for the United States
1/1/2021
This report is the fifth publication in a series of Electrification Futures Study (EFS) publications. The report presents scenarios of the U.S. electricity and energy systems through 2050. The scenarios encompass a wide range of future conditions, including the different electrification levels that were developed for the second EFS report. The scenario results include projected changes to the physical infrastructure of the U.S. power system, the utilization of that infrastructure, and estimates of other impacts of electrification to the power system and broader energy system.

The Shape of Electrified Transportation
1/1/2021
For more than a century, petroleum fuels have been relied upon to move people and goods within and between towns and cities, and on roads, railways, farms, waterways, and in the air. These fuels have provided reliable and convenient mobility options to power the modern global economy. However, these benefits have also created challenges associated with geopolitics, energy security, price volatility, and environmental impacts. Electric vehicles could dramatically disrupt the transportation energy demand landscape. Such a change comes with its own challenges and benefits. This report summarizes the trends driving vehicle electrification and explores the associated challenges and benefits.

Developing Markets for Zero Emission Vehicles in Short Haul Goods Movement
12/10/2020
This report examines the potential market share for zero emission heavy duty trucks (ZEHDTs) via simulation modeling, case studies, interviews, and a survey. It assesses the impacts of ZEHDTs on freight operations. Additionally, it compares the costs and benefits of using diesel, natural gas hybrid, and all-electric vehicles for 2020, 2025, and 2030. Lastly, this report presents recommendations for promoting and increasing the market share of ZEHDTs and hybrids.

Accelerating Ride-Hailing Electrification: Challenges, Benefits, and Options for State Action
12/2/2020
In the United States, use of ride-hailing services has grown at a steep rate over the last decade, and this trend is expected to continue. A rapid transition in ride-hailing fleets from internal combustion engine vehicles to plug-in electric vehicles (PEVs) would reduce emissions of greenhouse gases and other air pollutants, increase consumer exposure to PEVs, deliver maintenance and fuel cost savings to drivers, and improve the business case for fast charging infrastructure by increasing utilization. This paper identifies the benefits and challenges associated with transitioning vehicles driving on transportation network company platforms to PEVs and recommends specific actions states can take to support and accelerate the transition.

Affordability of Household Transportation Fuel Costs by Region and Socioeconomic Factors
12/1/2020
Transportation energy is an important component of household budgets. Vehicle fuel is over 3% of total household expenditures nationwide in the United States. The average annual expenditure of over $2,000 for vehicle fuel (mostly gasoline) is comparable to the total average household expenditures for electricity and natural gas combined. However, these average values vary geographically, and lower income households can face higher energy cost burdens. This study reveals the variation of household energy burdens across the country and provides localized data to support local decision making.
