Public Fleet Analysis and Regulatory Expertise

NREL combines analytical tools, an extensive stakeholder network, and regulatory expertise to help public fleets evaluate advanced vehicle technology and alternative fuel options.

Fleet Analysis

NREL's engineers and data scientists analyze vehicle telematics and fueling data, as well as electrical requirements, to determine how to optimize fleet vehicles via a transition to advanced vehicle technologies or alternative fuels, including electrification; what charging or fueling infrastructure is required to support those vehicles; and how much the new infrastructure will cost.

NREL legal experts also engage in policy analyses, regulatory compliance assessments, and rulemaking. NREL’s fleet efforts also extend internationally, including analyzing transportation systems to identify the most impactful and cost-effective transportation choices, such as alternative fuels, electrification, micromobility, and public transit.

Fleet Electrification

NREL fleet electrification experts analyze vehicle telematics and fueling data, as well as electrical requirements, to determine which vehicles can most easily transition to alternative fuels, what charging or fueling infrastructure is required to support those vehicles, and how much the new infrastructure will cost. NREL designs customized solutions for fleets that capture the benefits of electrification by applying a suite of analytical tools listed below, an extensive network of stakeholders, and regulatory expertise.

Fleet Tools

To support public fleet efforts that identify customized solutions, NREL has developed the following tools including those for the U.S. Department of Energy (DOE), particularly the Federal Energy Management Program (FEMP).

FEMP Federal Fleet ZEV Ready Center

Provides steps to select and acquire electric vehicles (EVs) along with an interactive PDF tracker.

FEMP ZEV Planning and Charging Tool

Leverages fueling transactions to predict the best vehicle candidates for electrification, group vehicles by parking location, and chart fleet transitions by year.

DOE U-Finder

Identifies utility contacts and incentive programs to find utility partners that can facilitate grid interconnection of EV chargers.

DOE VICE: Vehicle and Infrastructure Cash-Flow Evaluation Model

Evaluates the financial case for battery electric buses or natural gas vehicles. Contact Cabell Hodge for VICE extensions to other fuels and vehicle types.

DOE FleetDASH: Fleet Sustainability Dashboard

Tracks fuel consumption and regulatory compliance.

EVI-LOCATE: Electric Vehicle Infrastructure - Locally Optimized Charging Assessment Tool

Helps users plan EV charger placement and electrical upgrades integrated with cost estimator and dashboard by client.
