Reliable Backup Power Starts With a Proven Maintenance Program

At CoreUptime Power Systems, we believe preventive maintenance is the foundation of generator and ATS reliability. Our PM programs are designed to protect your operations from unexpected failures, reduce downtime, extend equipment life, and ensure your critical systems operate flawlessly under load—every time.

With over 43 years of combined generator, mechanical, electrical, and controls expertise, our team delivers a higher standard of care grounded in engineering principles, technical precision, and real-world field experience. Whether you operate a small commercial standby generator or a multi-megawatt critical power system, our PM contracts are tailored to your equipment, environment, load profile, and operational requirements.

​

Why Preventive Maintenance Matters

 

Backup power systems fail for only three reasons:

1. Lack of regular maintenance

2. Fuel contamination

3. Controls or ATS faults

Our maintenance programs strategically address all three.

A properly maintained generator is drastically more reliable during utility outages, emergency events, load transfers, or ATS sequencing. Regular inspections also help identify early signs of failure—before they become costly or operationally disruptive.

​

What’s Included in Our PM Contracts

Every contract is built around three pillars:
Engine Health • Electrical Integrity • Controls & ATS Reliability
