Specializing in industrial-grade generator services since 1988.
Our Story
Founded in 1988 as Western Machinery Electric Inc., Energen Systems has been dedicated to ensuring uninterrupted power for critical sectors across Northern California. From hospitals and data centers to manufacturing plants and government facilities, we provide the expertise that keeps essential operations running.
Our highly trained, EGSA-certified technicians deliver comprehensive diagnostics, preventive maintenance, engine repair, fuel testing, and NFPA 110 compliant load bank testing. We service every major generator manufacturer, with deep expertise in Cummins, Generac, Caterpillar, Kohler, and MTU systems.
As a C-10 licensed electrical contractor, we bring the full scope of electrical and mechanical expertise to every job. Our service territory spans the Bay Area to the Central Coast, with 24/7 emergency response capabilities across the region.
Our Values
Every decision starts with the question: does this serve the client? We build maintenance programs around your facility's needs, not a one-size-fits-all checklist.
We treat every generator as if it were our own. When we leave a site, the equipment is better than we found it.
Backup power exists for the moments when everything else fails. We hold ourselves to that same standard of dependability.
Good enough is not in our vocabulary. From documentation to torque specs, we do the job right the first time.
