At a high-altitude molybdenum mine in Colorado, dewatering the main pit meant getting power and controls down the pit wall to a series of skid-mounted pump stations. CEI produced the construction-ready electrical, instrumentation, and controls design: an overhead pole line carrying power and aerial fiber from the pit rim to the floor, pole-mounted transformers feeding each pump station, plus VFD pump controls, service-entrance and distribution equipment, grounding, and instrumentation. A power study covered short-circuit, protective-device coordination, arc-flash, and grounding, and CEI carried the work through 30/60/90/100% submittals, competitive bid analysis, construction support, and commissioning.
