North Star Solar Substation

Project Title: North Star Solar Substation
Client: Sentry Electric
Location: North Branch, Minnesota
Project Type: Substation

Emery Sapp & Sons were contracted to build the North Star Solar Substation. This substation was built to support an 880-acre solar farm. Due to the severe cold and deep frost, this job required us to over excavate all foundations 5 feet, and backfill with a flowable fill. We encountered ground water at 4 foot causing us to slurry the holes.

Surfacing – 179 TNS
Drilled Piers – 150 CY
Flowable Fill – 315 CY
