Geotechnical borings, test pits, and pile load tests allowed us to assess the site's suitability for BESS foundations and recommend a design.
Geotechnical and civil engineering for an Arizona BESS
June 2, 2026
To support Arizona’s clean energy goals and grid reliability, EDF power solutions North America (EDF) partnered with Arizona Public Service (APS) to develop and construct Beehive Storage—a 250 MW x 4-hour BESS located in Maricopa County, just north of Phoenix. EDF engaged Barr to conduct preliminary and design-phase geotechnical investigations and civil engineering services to optimize foundation design, reduce construction risk, and support the longevity of critical BESS infrastructure.
