Powering Progress: Advancing Transportation Electrification in Rural Southeastern Communities
7/1/2024
This report follows up on a 2022 Electrification Coalition report, Electric Vehicles (EVs) in Rural Communities, in addressing common roadblocks to transportation electrification in the rural, Southeast U.S. by providing case study examples of how communities have overcome these challenges. As rural communities are particularly susceptible to the effects of oil-dominated transportation systems, examples of successful electrification pathways are critical to wide-reaching EV deployment.
Customer-Focused Key Performance Indicators for Electric Vehicle Charging
6/18/2024
Electric vehicles (EVs) are a rapidly growing portion of the light-duty vehicle market, but their sustained success is closely linked to the reliability and ease-of-use of public EV chargers. To mitigate issues such as long wait times, difficulties starting charging sessions, and slow charging speeds, this report recommends two sets of numerically defined key performance indicators (KPIs) based on customer pain points that will help streamline the transition to clean vehicles. These KPIs target the following: charger access, starting and completing a charge, and charger-related safety and comfort.

Best Practices for EV Carsharing Programs
6/1/2024
Carsharing programs are common throughout the U.S., but few so far have focused on electric vehicles (EVs). Over the past six years, Forth Mobility has developed and trialed several EV carshare programs to identify and better understand the best practices and roadblocks to implementing these programs in underserved areas, such as in low-income and rural communities. This paper shares lessons learned by analyzing the following subject areas: revenue planning; site host, technology platform, and vehicle type selection; educational outreach; marketing strategies; and community organization partnerships.

Grid-Constrained Electric Vehicle Fast Charging Sites: Battery-Buffered Options
6/1/2024
America’s electric vehicle (EV) charging network is growing quickly, but many rural regions across the country experience electrical grid restraints that complicate the EV charger build-out. Government agencies must still devise strategies for deploying chargers in these locations where electrical grid capacity is more limited. This technical assistance case study provides guidance on battery-buffered options for EV charging sites with limited grid capacity, including infrastructure solutions, project economics, energy specification methods, technical considerations, and other relevant strategies.
Solar Power + Electric Vehicle Charging: Capturing Synergies in Minnesota
6/1/2024
A suite of aggressive climate action legislation, including a series of solar development commitments, has contributed to Minnesota reducing the carbon intensity of its power sector by 29% over 2013 levels. However, the carbon footprint of each sector has not dropped equally. In 2018, the transportation sector overtook power generation as the leading emissions producer statewide. The same focus on solar energy—combined with electric vehicle (EV) use—offers a vital opportunity for Minnesota to decrease transportation emissions. The analysis in this report examines the underdeveloped synthesis between solar production and EV charging, presenting seven key findings paired with relevant recommendations to transform the market and decrease transportation-based emissions.

Physical Safety and Security at Electric Vehicle Charging Sites
6/1/2024
As electric vehicle (EV) demand grows, so does the need for more robust EV charger safety and security. EV charger host sites must work to uplift driver and passenger confidence by incorporating design elements that promote greater safety and security. This help sheet outlines various best practices for public EV chargers. While the help sheet indicates the higher monetary costs attributed to greater safety and security measures, it also clarifies the greater repeat customers rates that result from these improvements.
Embedding Equity into Community EV Readiness Planning
6/1/2024
New electric vehicle (EV) infrastructure presents an opportunity to imbed greater equity into surrounding communities. Doing so ensures that all community members are heard during the nationwide clean transition, and also streamlines the process of securing funding from federal offices that prioritize equity-based initiatives such as Justice40. This help sheet examines pathways to more effectively embed equity considerations into EV charger development, including strategies for community outreach, zoning, needs assessments, receiving funding, and more.
Navigating Options for Transportation Electrification and Solar Charging: Steps and Lessons Learned in Montana Communities
6/1/2024
Drawing on analysis and outreach in three Montana communities (Missoula, Bozeman, and Whitefish), this report provides guidance and best practices for other towns and cities across the country on how to effectively implement electric vehicle (EV) transportation options into their communities. The report incorporates logistical considerations—vehicle types, chargers, electricity generation—and useful strategies—effective stakeholder engagement, coordinating EV charging and renewable energy generation, and more—to cover the technological, economic, and environmental aspects of the transition to EVs.

Hot Weather Impacts on Battery-Electric Transit Buses
5/1/2024
This help sheet provides information about the impact of hot weather on battery electric buses (BEB) that transit fleets should consider when integrating BEBs into their fleets and a checklist of relative precautions that transit agencies can take during the deployment planning process to ensure optimal performance of BEBs in hot weather.
Powering Seattle Fleets: A Charging Infrastructure Strategy for Battery-Electric Medium- and Heavy-Duty Vehicles
5/1/2024
Within the Puget Sound region, transit agencies are positioned to lead in a surge of electric medium- and heavy-duty vehicles (MHDVs). Seattle City Light (SCL), the municipal electric utility of Seattle, is responsible for both ensuring sufficient infrastructure and grid capacity to meet the future energy requirements of electrification of these vehicles. This report serves to inform development of the charging infrastructure strategy for the utility through analysis of projected charging infrastructure development and local vehicle data. The analysis resulted in seven broad recommendations for the utility, addressing en-route charging, depot charging, internal operations, and communications with fleets.

Battery-Powered Bargains? Assessing Electric Vehicle Resale Value in the United States
4/17/2024
This study analyzes the depreciation trends of all-electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) compared to conventional gasoline vehicles, based off a database of nine million pre-owned vehicles listed online between 2016 and 2022. The study found that while EVs and PHEVs have depreciated at a faster rate than gasoline vehicles, the trend is changing as newer models of EVs have had higher retention rates than older model years.

The Role of Biofuels and Biomass Feedstocks for Decarbonizing the U.S. Economy by 2050
4/11/2024
Bioenergy holds significant potential to transform the transportation sector, helping to eliminate hard-to-abate sources of emissions, such as aviation, that lack viable electrification alternatives. Further, integrating more biomass-based electrification pathways will diversify the country’s electrical grid, increasing its stability in the future. This study uses process-based analyses of biomass resources and pathways to demonstrate the decarbonization potential and cost-efficiency of scaling bioenergy in the United States.
