About
3 Phase Associates, LLC is a licensed professional electrical engineering and consulting firm headquartered in Chattanooga, TN, holding active PE registrations across more than a dozen states throughout the Southeastern United States — including Tennessee, Georgia, Alabama, Kentucky, Mississippi, and Virginia. Unlike traditional electrical contractors, this firm operates at the engineering and design level, making them a critical resource for facility managers, utilities, and project owners who need power system expertise before a single conduit is pulled. Their core capabilities span power substation engineering and design, overhead and underground distribution line design, transmission line engineering, and SMART Grid and renewable energy integration — services that directly support industrial campuses, institutional facilities, government infrastructure, and large mixed-use developments navigating utility interconnection or capacity upgrades. For Chattanooga-area property portfolios with complex power distribution requirements, 3 Phase Associates brings structured EPC (engineering, procurement, and construction) partnership options and full program management from concept through implementation and testing. Their telecommunications engineering practice adds value for facility managers coordinating low-voltage infrastructure alongside major electrical system upgrades. Cybersecurity protection and AI tools round out a service mix that reflects the evolving demands of modern building and grid operations. Their CAD design and 3D modeling capabilities — including virtual reality system design — allow facility teams and project stakeholders to visualize power infrastructure before construction begins, reducing costly field changes. With multi-state licensure and a stated mission of surpassing client expectations, 3 Phase Associates is well positioned for facility managers overseeing large-scale power distribution projects, utility-side coordination, or renewable energy and DER integration across commercial and institutional properties in Tennessee and the broader Southeast.
