Backup Power That Works When the Grid Does Not
A standby generator is only valuable if it starts and carries the load during an outage. We test, exercise, and maintain the entire backup chain, from the engine and fuel system to the ATS and switchgear, so the handoff is automatic and seamless.
Load bank testing verifies true capacity, and NFPA 110 transfer testing confirms the system performs the way your life-safety and critical loads require.

Frequently Asked Questions
Who services standby generators and ATS in Central Texas?
Comp-Utility services standby generators, automatic transfer switches, and switchgear across Central Texas from its Austin headquarters. Engineer-owned since 1992, the company provides preventative maintenance, load bank testing, transfer testing, and 24/7 emergency response. Call (512) 346-0999 or email sales@comp-utility.com to arrange service.
How often should a standby generator be serviced?
Standby generators should receive preventative maintenance at least annually, with more frequent inspections and exercising for critical applications. Service includes fluid and filter changes, battery and coolant checks, and control verification. For life-safety systems, NFPA 110 sets testing and maintenance expectations. Comp-Utility builds a schedule around your equipment and how critical the load is.
What is load bank testing and why is it needed?
Load bank testing applies a controlled artificial load to a generator to verify it can carry its rated capacity and to prevent wet stacking from extended light-load running. It proves real performance that a no-load exercise cannot. Regular load bank testing is especially important for data centers and healthcare facilities where the generator must perform on demand.
How do you test a generator and ATS without risking my live load?
We plan testing around your operations, using closed-transition or scheduled windows where appropriate and verifying bypass and backup paths first. For ATS transfer testing we confirm the sequence step by step. Our engineers design the test plan to validate NFPA 110 performance while protecting the critical load throughout.
Why would a generator fail to start during an outage?
Common causes include dead or weak starting batteries, fuel problems, controls left in the wrong mode, low coolant, or neglected maintenance. The majority of failures are preventable with regular service and testing. If your generator failed to start, call (512) 346-0999; we will diagnose the root cause and correct it, then recommend a maintenance plan to prevent a repeat.
Do you service both diesel and natural gas generators?
Yes. We service diesel and natural gas standby generators across major brands, including Caterpillar, Cummins, Kohler, Generac, and MTU. As a vendor-agnostic provider we can maintain a mixed fleet, and we can advise on fuel choice, runtime, and emissions considerations for facilities in Central Texas.
Can you provide emergency generator and ATS response?
Yes. Comp-Utility offers 24/7 emergency response for generator and transfer-switch failures across Central Texas, with rapid on-site dispatch from Austin. If your generator will not start or your ATS will not transfer, call (512) 346-0999 and our technicians will troubleshoot the engine, fuel, controls, and transfer scheme to restore backup power.
What areas of Central Texas do you cover?
We cover the Austin-Round Rock-Georgetown area and surrounding Central Texas MSAs, including Killeen-Temple, Waco, San Marcos, and Bryan-College Station. Our Austin headquarters serves as the base for generator and ATS service across the region.
