ePower Network was founded in 2010 with a simple premise: the companies protecting critical infrastructure deserve better service than they were getting. Generic vendors with no specialized knowledge, poor response times, and no accountability.
We built ePower differently — specialists, not generalists. Factory-trained engineers, not overnight hires. A genuine guarantee, not fine print.
Today we serve 30+ enterprise clients across healthcare, financial services, government, technology, and education — managing power equipment from 1 kVA to 1 MW capacity.
1020 Segovia Circle, Placentia, CA 92870 — with additional field offices in San Diego and Los Angeles.
Established in 2010 by Greg Marquez and Eric Lee — industry veterans with deep roots in critical power.
Boeing, UCLA, Netflix, Northrop Grumman, Hoag Hospital, CalTech, and 25+ more enterprise organizations.
100% satisfaction guaranteed or your service is free. No exceptions, no fine print.
