SRP, Plus Power and Avondale To Break Ground on Large-Scale Battery Storage Facility

SRP, Plus Power LLC, and officials from the City of Avondale will soon break ground on the new large-scale battery facility, Sierra Estrella Energy Storage. The facility will store up to 250 megawatts (MW), or 1,000 megawatt hours (MWh), which will serve SRP customers during times of peak electricity demand and facilitate the integration of renewable resources into the SRP power system. This is enough stored energy to power more than 56,000 average size homes for a four-hour period.

The Sierra Estrella facility is one of two battery storage projects SRP recently announced with Plus Power that is scheduled to come online by summer 2024.

Plus Power will design, build, and operate the project to updated national codes and standards for Battery Energy Storage Systems, which incorporate lessons learned from incidents at other battery facilities. Sierra Estrella will utilize state-of-the-art lithium-ion technology with batteries assembled in the U.S. Additionally, Plus Power is closely coordinating with the Avondale Fire Department, working to prepare a thorough Emergency Response Plan and conduct onsite training to ensure that local first responders are directly engaged in safety planning throughout project design, construction, and operation.

The Sierra Estrella Energy Storage facility will be a good neighbor and a valuable asset to the surrounding community for decades to come. The project will provide necessary power capacity to the region with no air polluting emissions. As a static facility with insignificant traffic and minimal municipal services, the Sierra Estrella facility will have little impact on neighbors. Significant project benefits to the community include:

  • High-paying construction jobs
  • Enhanced resiliency from a new, state-of-the-art power resource
  • Expanded property tax base for the local district

The ground breaking ceremony will take place on April 12 from 10:00-11:00 a.m.
