What Electrical Technologies and Supply Inc does

Electrical Technologies and Supply Inc is a Golden, Colorado-based manufacturers' representative and field service firm founded in 1995 by Gerald A. Suman. The company specializes in engineered electrical products with an emphasis on power transformers and substation equipment for generation, transmission, and distribution, serving electrical utilities, large industrial customers, EPC firms, renewable energy developers, and independent power producers across the western half of the United States (Arizona, Colorado, Wyoming, Texas, New Mexico, Oklahoma). The company operates two divisions: a Sales division representing approximately 14 domestic and international manufacturers of transformers, instrument transformers, disconnect switches, batteries and DC chargers, control panels, oil filtration systems, monitoring equipment, cables, reactive power compensation, BESS, and solar modules; and a Field Service division providing turnkey installation, oil processing, acceptance testing, and maintenance for power transformers up to 765 kV equipment class. Electrical Technologies also manufactures its own proprietary Passive Cooling Chamber (PCC) product, a passive water-based battery temperature management system designed to extend substation battery life.

Revenue is generated via commissions on equipment sales through manufacturer representation contracts plus project-based fees for field service engagements. The business is privately held by the Suman family, with Preston Simon serving as President of Sales, Tony Suman as President of Field Services, and John Suman as Vice President and Director of Safety. The company employs 12 people and reports 20+ years without lost-time or work-related accidents under its corporate safety program.
