Investment in Public EV Charging in the United States

This brief provides an overview of the historical and current state of government, private sector, and electric utility investment in publicly available charging infrastructure in the United States. With increasing funding available from both the electric utility and government sectors, charging service providers and related stakeholders have a significant, near-term opportunity to grow the public EV charging network in the United States and reduce the dependency on government subsidization over time.

Making Electric Vehicles Work for Utility Customers

This report provides a framework for helping consumer advocates analyze EV policy options (including ratepayer-funded transportation electrification programs) and ensure that the benefits of EV adoption are equitably distributed across customers.

Residential Electric Vehicle Rates That Work

This report from the Smart Electric Power Alliance (SEPA) and their partners explores how utilities can influence home charging behaviors through EV time-varying rates that incentivize residential customers to charge off-peak thereby minimizing distribution system impacts and avoiding the need for costly infrastructure upgrades and investments. The survey results show that customers on an EV-specific time-varying rate were more familiar with the rate rules and more likely to charge off-peak compared to their generic time-varying rate counterparts.

Vehicle-Grid Integration

This brief lays out the challenges and opportunities of vehicle-grid integration (VGI). Electric vehicles (EVs) can help increase the utilization of existing electrical grid assets and put downward pressure on electricity rates by decreasing the average cost of delivering electricity. Many aspects of VGI, including time-of-use (TOU) rates and demand response programs have similar characteristics to other grid management programs.
