- Considering Interoperability for Electric Vehicle Charging: A Commission Case Study, Fall 2022
As adoption of electric vehicles (EVs) increases across the United States and charging equipment to power vehicles is installed, the electricity system, states, utilities, EV manufacturers, EV supply equipment (EVSE) manufacturers, and stakeholders are grappling with how to ensure smooth integration of these resources. Interoperability ensures that communication, coordination, and integration of devices, such as electric vehicle supply equipment (EVSE), are integrated efficiently and effectively.
- Mini Guide on Transportation Electrification: State-Level Roles and Collaboration among Public Utility Commissions, State Energy Offices, and Departments of Transportation, Summer 2022 This mini guide describes the unique and vital roles State Energy Offices, Public Utility Commissions (PUCs), and Departments of Transportation (DOTs), as well as State Environmental Agencies, Consumer Advocates, and other important state-level partners each have to support the ambitious electric vehicle (EV) adoption goals in many states and implement EV rollout.
- Models for Incorporating Equity in Transportation Electrification Considerations for Public Utility Regulators, Summer 2022 Momentum for the electric vehicle (EV) transition is well underway, and the utility sector plays an important role in supporting its success. For frontline communities, the transition offers a promising solution to improve environmental and public health outcomes, economic development, affordability, and transit equity. However, the transition will need to involve care and intention to ensure that the needs of underserved communities are prioritized throughout the planning, decision-making, and implementation processes. States --- through Public Utility Commissions and other state agencies --- have taken the lead in some cases, as describe in this paper. Whether driven by state commissions or utilities themselves, utilities have a range of options available to ensure equity is central in their transportation electrification plans and programs by drawing from a variety of existing and emerging experiences.
This issue brief provides an overview of the utility programs and business models that are intended to center equity and captures key considerations for state utility regulators around these models.
- Electric Vehicle Interoperability Considerations for Public Utility Regulators, Summer 2022 Electric vehicles (EV) are an increasingly important component of many state and federal efforts to decarbonize both the electric and transportation systems. Although this growth will not be uniform across the country and some states will move faster than others, the need for charging infrastructure will be vital to the widespread adoption of EVs. As cars are driven across utility service territories and state borders, ensuring that EV owners can charge their vehicles reliably is critical. To enable widespread charging for customers and a consistent and reliable experience across vehicle manufacturers, charging station developers, and utility territories, it is essential to adopting industry standards that emphasize interoperability by all actors.
This issue brief provides an overview of EV interoperability benefits and opportunities, describes where in the charging ecosystem interoperability is relevant and what standards are available, and includes a snapshot of recent state public utility commission actions to ensure interoperability in charging infrastructure.
- Electric Vehicles: Key Trends, Issues, and Considerations for State Regulators, October 2019
