US EV Electricity Demand Growth Shows Moderation

## Evolving Dynamics in EV Energy Demand

New data from the U.S. Energy Information Administration (EIA) indicates a notable shift in the growth trajectory of electricity consumption by light-duty electric vehicles (EVs) in the United States. While overall EV electricity use has expanded considerably, the rate of this growth is now moderating, suggesting an evolving landscape for energy planners and infrastructure developers.

The EIA's analysis highlights that electricity consumption by light-duty EVs increased by 8% in the first half of 2024 when compared with the second half of 2023. This figure represents a deceleration from the more rapid growth rates observed in preceding periods, which ranged between 13% and 24% over comparable six-month intervals.

This moderation in growth follows a period of robust expansion. Since the first half of 2023, total electricity demand from light-duty EVs has more than doubled, reaching nearly 14 billion kilowatt-hours in the first half of 2024. This sustained increase underscores the significant, albeit now decelerating, impact of EV adoption on the electricity grid.

Several factors are contributing to this shift, as identified by the EIA. These include a slower rate of new EV sales, changes in available vehicle models, and the expiration of certain U.S. federal tax credits in 2023. Such policy and market dynamics can influence consumer purchasing decisions and, consequently, the rate of new EV deployments, which directly impacts electricity demand growth.

For stakeholders in the refined fuels and energy sectors, this trend necessitates a re-evaluation of future demand projections. While the long-term trajectory for EV adoption and associated electricity demand remains upward, the immediate-term growth rates may require more granular forecasting to ensure efficient resource allocation and infrastructure development.

The refined fuels industry, in particular, can monitor these developments to understand potential shifts in the broader energy mix. A slower, yet still positive, growth in EV electricity demand provides a more predictable environment for managing existing fuel supply chains and planning for future energy transitions. Adapting to these evolving growth rates will be crucial for maintaining stability and efficiency across the energy supply chain.
