In a recent meeting of the Los Alamos County Board of Public Utilities, significant discussions centered around the electrification infrastructure necessary to support future growth in the region. The meeting, held on June 25, 2025, highlighted the challenges and solutions related to capacity constraints in the electrical distribution system, particularly in the West Side and White Rock areas.

A key focus was the need for an East Gate substation to alleviate capacity issues stemming from the existing Townsite substation. As demand for electricity increases, the current infrastructure has reached its limits, necessitating the construction of new facilities to ensure reliable service. The discussions revealed that the Eastgate substation will be crucial for accommodating new electrification growth, as it will serve loads previously managed by the Lass and Townsite substations.

In White Rock, the approach was somewhat more straightforward. The board discussed the construction of a new distribution feeder to balance the load more effectively across the area. This strategic move aims to enhance the reliability of the electrical system and prepare for future contingencies, ensuring that the infrastructure can handle peak demands without overloading existing feeders.

The meeting also addressed the need for upgrading existing conductors and building new feeders to support the anticipated load growth. The analysis indicated that, under high demand scenarios, up to six new distribution feeders may be required from the Eastgate substation to manage the increased load effectively. This proactive planning is essential to maintain service quality and prevent outages, particularly in light of potential contingencies, such as equipment failures or accidents.

Additionally, the board discussed the importance of distinguishing between system improvement upgrades and asset replacement needs. As many existing assets approach the end of their operational lifespan, the board emphasized the necessity of planning for both immediate upgrades to support electrification and long-term asset replacements to ensure system reliability.

The financial implications of these infrastructure projects were also a topic of discussion, with estimates for system improvements and asset replacements expected to be presented in future meetings. The board acknowledged that while these estimates provide a framework for planning, actual costs may vary based on the county's approach to asset management and replacement strategies.

In conclusion, the meeting underscored the critical need for infrastructure enhancements in Los Alamos County to support electrification growth. As the community continues to expand, the board's proactive measures in planning and upgrading the electrical distribution system will be vital in ensuring reliable service and accommodating future demands. The anticipated next steps include further financial assessments and continued discussions on the implementation of these necessary upgrades.
