Commercial Electrical Contractor

Electric Supply Source (ESS) is the El Paso – Las Cruces team facilities call when they need a commercial electrical contractor that moves fast and gets it right the first time. We engineer and install 277/480V distribution, new and upgraded services, switchgear, and feeders; execute tenant improvements without disrupting operations; and deliver resilient power with generators, ATS, and load-bank commissioning. Our crews handle lighting and controls (including egress and networked systems), EV charging infrastructure, and low-voltage scope data/fiber, CCTV, access control, and fire alarm. Whether plan-and-spec or design-build, we manage utility and permit coordination, maintain NFPA 70/70E compliance, and document everything with labeled panels, test results, IR thermography, and photo-rich closeouts. Expect weekend changeovers to minimize downtime, clean site practices, and clear communication from kickoff to inspection sign-off. Licensed, insured, and local; ESS offers 24-hour quote turnarounds and rapid emergency response, supporting property managers, GCs, healthcare, education, industrial, retail, and public sector facilities across West Texas and Southern New Mexico.

Detailing Steps

Step 1

Site Walk & Scope Capture

We visit your facility to confirm loads, voltage (120/208 or 277/480V), clearances, and access. We review drawings, snap photos, note shutdown constraints, and flag code/safety items so the estimate matches real-world conditions.

Step 2

Estimate & Plan (NEC-Compliant)


You’ll get a clear, itemized quote within 24 hours—often with Good/Better/Best options. We handle utility coordination, permitting, submittals, and schedule planning (including weekend or after-hours changeovers) to minimize downtime.

Step 3

Installation & Safety


Licensed, insured crews complete demolition, feeders/conduit, gear and panel installs, lighting/controls, and device terminations. We follow NFPA 70E lockout/tagout, daily housekeeping, and keep operations running where possible.

Step 4

Testing, Inspection & Close-Out


We torque-test terminations, perform IR thermography where applicable, label panels/circuits, and support AHJ inspections. You receive as-builts, test results, photos, and a maintenance checklist—plus options for ongoing PM service.
