Our customers are ready for the next unplanned power outage. Are you? We maintain all makes and models of generator systems-from the fuel system to the transfer switch. Electro-Motion Provides Bay Area Generator Maintenance You Can Rely On For over 50 years, we've been helping businesses build and maintain the backup power systems they need to be ready for the next unplanned power outage. Our story began in 1967, when Eric Loeffler and his nephew Hans Krueger started manufacturing generators for the fast-growing companies that were appearing all over the Bay Area. Over the next few decades, we grew up with Silicon Valley-expanding our product line, securing several patents, and working with many of the biggest tech companies before they were household names. In the years since, we've cemented our reputation as the premier provider of emergency power system maintenance to businesses in Silicon Valley and the San Francisco Bay Area.
