APS discusses critical substation expansion and safety measures with local officials

In a recent meeting held on December 3, 2024, the Chino Valley Planning and Zoning Commission delved into critical discussions surrounding the expansion of an electrical substation operated by Arizona Public Service (APS). The atmosphere in the room was charged with curiosity and concern as community members sought clarity on the implications of this project for their neighborhood.

The primary focus of the meeting was the necessity for the substation's expansion, which aims to upgrade existing equipment and enhance the power grid's efficiency. An APS representative explained that the project involves installing newer electrical equipment and a control house, ensuring that the infrastructure can support future energy demands. Importantly, the representative emphasized that this expansion is unrelated to solar energy initiatives, a point that had been raised multiple times by attendees.

A significant topic of discussion was the height of the proposed wall surrounding the substation. According to APS regulations, a minimum wall height of ten feet is required for critical infrastructure, as mandated by the Department of Homeland Security. The existing wall meets this requirement, and no increase in height is planned. This regulation aims to enhance security and safety, addressing concerns about unauthorized access to the facility.

Fire safety also emerged as a key concern during the meeting. Attendees questioned how electrical fires would be managed, particularly given the lack of water access at the site. The APS representative noted that fire departments require a Knox box—a secure access point—outside the facility to ensure they can respond effectively in emergencies. However, due to the specialized nature of electrical fires, APS personnel must be present to assist firefighters, as they are trained to handle such situations.

The meeting concluded with a sense of understanding among attendees regarding the complexities of managing electrical infrastructure and the safety measures in place. As Chino Valley continues to grow, the discussions highlighted the importance of balancing community needs with the demands of modern energy requirements. The expansion of the APS substation is a step towards ensuring that the power grid remains robust and reliable for the future, while also addressing the safety concerns of local residents.
