The Los Alamos County Board of Public Utilities meeting on June 4, 2025, spotlighted the significant impact of electric vehicle (EV) adoption on the local power grid. As the county anticipates a surge in EV usage, officials discussed the potential for increased peak load, emphasizing the need for strategic planning to manage this growth.

A key takeaway from the meeting was the projected increase in electricity demand due to electrification across various sectors. By 2055, the county could see an additional peak load of up to 44 megawatts if all transportation and home electrification efforts are fully realized. This figure is part of three scenarios presented: a high scenario of 44 megawatts, a medium scenario of 28 megawatts, and a low scenario of 13.5 megawatts.

The discussion highlighted the diverse charging behaviors of EV owners. Approximately 30% of drivers plug in their vehicles immediately upon returning home, while 40% may schedule charging for later, taking advantage of time-of-use rates. The remaining drivers rely on slower, level 1 charging, which has a lesser impact on the grid. This variability in charging habits is crucial for understanding the overall demand on the electrical system.

Officials also noted that about 80% of EV owners charge their vehicles at home, which further influences the grid's load dynamics. The meeting underscored the importance of considering these factors in future energy planning to ensure that the infrastructure can support the growing number of electric vehicles in the county.

As Los Alamos County moves forward, the insights from this meeting will play a vital role in shaping policies and strategies to accommodate the anticipated rise in electrification, ensuring a reliable and sustainable energy future for its residents.
