Los Alamos County reviews solar and battery storage adoption rates for climate action plan

The Los Alamos County Board of Public Utilities held a work session on June 4, 2025, to discuss various scenarios regarding solar energy adoption and battery storage within the community. The meeting focused on the potential for solar panel installation and the implications of battery storage for residents.

One of the primary topics was the assumption that 50% of homes in Los Alamos would have solar panels by a specified future date. A representative explained that this figure was based on optimistic projections, referencing South Australia, where solar adoption has reached 37% due to favorable financial incentives and high electricity costs. The speaker acknowledged that while 50% is an ambitious target, it serves as a boundary condition for scenario planning, contingent on the enactment of climate action objectives.

Concerns were raised by board members regarding the feasibility of achieving such a high percentage of solar installations, particularly given the community's geographical constraints and existing building orientations. The representative noted that while new construction may be limited, the rate of solar permits has increased significantly since 2019, suggesting that continued incentives could drive adoption closer to the 50% mark.

The discussion also included the assumption that 20% of homes would utilize battery storage. The rationale behind this figure was linked to the introduction of time-of-use rates, which could make battery storage more appealing for residents. The representative indicated that without such financial mechanisms and additional electrification efforts, the percentage of homes with battery storage might be lower.

Additionally, the board examined the assumption that 80% of electric vehicle drivers would charge their vehicles at home. Clarification was provided that this referred specifically to single-family homes with dedicated parking, while the remaining 20% would likely reside in multi-unit dwellings.

The meeting concluded with a recognition of the challenges and opportunities presented by the transition to renewable energy sources in Los Alamos County. The board emphasized the importance of continued dialogue and planning to navigate the community's energy future effectively.
