Support of Battery Energy Storage Systems with Helical Pile Foundations-Video

Video Transcription

Video Summary

The presentation explains how helical piles can efficiently support battery energy storage systems (BESS). They offer rapid installation, capacity verification through torque measurements, no drill spoils, and the ability to be removed and reused, reducing end-of-life reclamation costs.<br /><br />Design typically addresses substantial axial loads and wind or seismic forces. Engineers use equipment dimensions, vendor support requirements, site conditions, and applicable codes to determine loads, pile layout, shaft size, bearing plates, and installation depth. Lateral performance often governs shaft selection.<br /><br />A test installation program—installing and removing piles across the graded site—helps identify soil variability and optimize production designs. In a Texas project with 728 piles, testing enabled a smaller bearing-plate configuration and reduced pile length from 10 to 9 feet, lowering costs.<br /><br />Overall, helical piles provide a fast, adaptable foundation solution, while test installations can improve reliability and yield significant project savings.
