The project
Aragorn Substation
Applied High Voltage, a subsidiary of worldwide renewable energy contractor Signal Energy, contracted Park Range Construction to install the foundations for transmission lines at the Titan-Aragorn Solar Substation in Culberson County, Texas.
The site was extremely remote, and conditions were very hot and dry. Our crew drilled 74 battered 4½-inch micropiles to a depth of 14 feet, completing the installation in seven days.
Five load tests were performed to confirm the design.
