Plans for a large battery energy storage system near the unincorporated communities of Eden Valley, Harmony Grove and Elfin Forest in San Diego County have been withdrawn after significant community opposition. Virginia-based power company Applied Energy Services had proposed the Seguro Energy Storage project, but faced backlash from residents and local officials over safety concerns about the inherent volatility of lithium battery facilities.

Why it matters

Battery energy storage systems are critical infrastructure for the transition to renewable energy, but siting these facilities in residential areas raises serious safety risks. The withdrawal of this project highlights the challenges of balancing clean energy needs with community concerns over potential hazards like chemical fires and toxic fumes.

The details

The Seguro project would have been one of the largest battery storage facilities of its kind, and the only one proposed in a residentially zoned area surrounded by homes. Critics argued that BESS facilities are inherently volatile and at high risk of catching fire, with lithium battery fires being extremely toxic, hard to extinguish, and lasting for several days. The nearby Escondido City Council had also passed a resolution opposing the project.

  • The Seguro Energy Storage project was first proposed in 2023.
  • Applied Energy Services formally withdrew its application on Friday, April 4, 2026.

What they’re saying

“We understand the importance of BESS facilities to our energy transition, but we must ensure that the safety of communities is taken into consideration when siting these facilities that have a strong, well-documented history of chemical fires.”

— JP Theberge, Member, Elfin Forest/Harmony Grove Town Council

“Easement rejection by the nearby hospital and nearby business park, as well as stricter siting requirements, made this project a no-go. We're glad the developer has withdrawn their application. We wish them the best and hope they find a site that is suitable while also protecting neighborhoods from potential thermal runaway fires.”

— JP Theberge, Member, Elfin Forest/Harmony Grove Town Council

What’s next

The withdrawal of the Seguro Energy Storage project leaves the local community relieved, but the need for safe and responsible siting of battery storage facilities remains an ongoing challenge as the transition to renewable energy continues.

The takeaway

This case highlights the delicate balance between the critical need for energy storage infrastructure and the valid safety concerns of local residents. As battery technology advances, policymakers and developers must work closely with communities to ensure that these facilities are located in appropriate areas that minimize risks to public health and the environment.
