Our company started in 2003 when Relectric Supply Company, LLC, our Components subsidiary, was founded in San Jose, CA. Over the next 10 years, in response to customer demand and market opportunity, the business expanded to include electrical testing and engineering services. Due to multiple acquisitions by 2016, our portfolio of companies was significantly expanded to include Switchgear Unlimited (Plant City, FL), DYMAX Services (St. Paul, MN), Energy Systems Services (Stow, OH), West Coast Switchgear (Cerritos, CA), and Transformer Testing and Repairs (Fairfield, CA).
Since then, many great companies have joined the RESA Power family and we now total over 20 locations across the USA and Canada that enable us to serve customers nationwide as a full-service provider of electrical power systems solutions.
We are now widely regarded as the “Acquirer of Choice” within our industry and expect to welcome many more companies into our fold over the next few years. If you would like more information about joining with RESA Power, please fill in our online form. (link to the acquisition page).
Originally, back in 2012 name “RESA” came from the combination of two company’s names – Relectric (founded in 2003 in San Jose, CA) and Satin American (founded in 1928 in Shelton, CT) – which laid the foundation of our company.
Over time, RESA has grown significantly and increased the significance of its meaning, and we believe that our current motto accurately represents how we now are in the present – “Reliable and Safe. The Power of Us”.
