A different type of engineering firm. We aren't just engineers; We’re a team devoted to quality.

Our history

TransPower Testing Inc. (TPT) began out of a family garage in Orange County in 1992. The goal from the day of its inception was to provide quality engineering services, around the clock. After two decades, that goal remains the same. TPT was formed on a foundation of industrial power engineering experience acquired from companies like GE over a span of 20 years. Initially, our focus had been power generation and controls, but over time, the needs of our customers led us into critical power systems of some of the most advanced technological companies and organizations in the country under the same founding management.

We’re headquartered in Orange County, California and our UPS services can be found in both Northern and Southern California, Nevada, and Hawaii.

Our beliefs

We pride ourselves on being an agile company that moves quickly to take care of our clients needs. Whether we’re on the field or in the office, our top priority is always the same - making sure our clients are happy and confident with the services we provide. Today, we still provide services for the same customers that gave us a chance when we first started up our business over 20 years ago, which we believe is representative of the quality of our people and work. Our team consists of caring problem solvers who can’t walk away from an issue until the root of the problem is resolved. This is the fundamental trait that our company is and will continue to be built upon. We work hard to make sure our employees are trained to handle any UPS issues they may encounter on the field, however, finding individuals with the same work ethic and attention to detail we’ve adapted at TransPower Testing is what we believe to be most vital to our growth and success.
