Edwards Sanborn Solar Storage Facility

The Edwards Sanborn Solar Storage Facility aims to be the world’s largest solar-plus-storage project. The project is located in Kern County, on land leased from Edwards Air Force Base as well as on adjacent private land. Once built, the project could have a capacity of up to 1,118MW of solar photovoltaic (PV) and 2,165 megawatts per hour (MWh) of battery storage.

Project Facts
  • Kern County, CA
  • 346 MWac of Solar Modules
  • 1,501 MWh of Battery Storage

The Challenge

The project aims to develop a PV solar facility and associated infrastructure, including service roads, above- and below-ground transmission lines, conversion station, solar arrays, substation, battery storage, O&M facilities, gen-tie lines, and more. With a vast project site spanning 6,000 acres, the project had to contend with complex permitting and compliance challenges, as well as outreach to and consideration of numerous stakeholder groups.

The Solution

Dudek provided comprehensive support for the project. Biologists, archaeologists, and technical experts prepared technical studies (including pre-construction desert tortoise clearance surveys) and an EIR. Compliance experts are monitoring construction activities of more than 700 personnel to ensure compliance with federal, state, and local permit requirements. Using ArcGIS, Collector Map, and Dudek Forms, our compliance monitors track, map, and relay project information on the 6,000-acre site, so the client, contractors, and subcontractors have access to near-real-time monitoring and compliance information.

The Impact

Once constructed, the solar storage facility will power over 158,000 homes. This solar generation and battery storage will decrease annual CO2 emissions by 307,000 tons as compared to traditional electricity generation.
