The Board of Supervisors in San Diego recently approved new policies to regulate the approval and operation of future energy-storage sites in unincorporated areas. This decision comes in the wake of a lithium battery fire at an Escondido storage facility that led to evacuation orders and warnings. While the board did not impose a moratorium on new facilities, they did vote 4-1 to implement additional requirements for fire suppression technical reports and disclosures for battery energy storage systems (BESS).
During a public hearing, supervisors discussed the need to ensure that new BESS facilities exceed current code requirements to address concerns raised by residents about the safety of these systems in their communities. The board also considered proposals related to modular designs and following National Fire Protection Association guidelines for BESS facilities.
Following an amendment from board Vice Chair Terra Lawson-Remer, the county fire chief will analyze residential buffer distances based on plume modeling and develop a plan for BESS facilities. This decision aims to balance the need for climate-friendly battery storage infrastructure with the safety of residents.
Board Chairwoman Nora Vargas emphasized the importance of public safety while acknowledging the role of battery storage facilities in renewable energy. She advocated for approving best practices, including fire suppression plans, rather than imposing a moratorium on new projects.
Despite the board’s decision, some residents called for a moratorium on building new lithium battery storage facilities in neighborhoods. Concerns have been raised about the impact of these facilities on property values, light pollution, and noise nuisance.
While opponents of a moratorium highlighted the role of BESS facilities in preventing blackouts and supporting the county’s climate action goals, proponents emphasized the need for stringent safety standards to protect residents from potential risks associated with these facilities.
The recent lithium battery fire at the San Diego Gas & Electric facility in Escondido added urgency to the board’s discussions on regulating energy-storage sites. While no injuries were reported, the incident prompted evacuation orders for nearby businesses.
Supervisors faced a balancing act between promoting renewable energy goals and ensuring the safety of residents in light of recent incidents involving BESS facilities. Moving forward, the county will continue to evaluate the impact of battery storage infrastructure on communities and develop strategies to mitigate potential risks.
Overall, the decision to approve new regulations for energy-storage sites reflects the county’s commitment to promoting sustainable energy practices while prioritizing public safety.
