Generator and ATS: The Day Your “Optional” Became Essential

PSE Designs employee discussing generator and automatic transfer switch (ATS) backup power options with a client

For many businesses, a backup generator isn’t considered a necessity. However, when a massive storm hits during busy season, that “optional” system is what keeps your business up and running.

At PSE Designs, we help you treat backup power as a planned system, not an afterthought. That means sizing the generator to the building’s real electrical load, designing an automatic transfer switch (ATS) that responds the moment utility power drops, and confirming the fuel supply can support the outage durations that actually matter to you.

Our Electrical Engineering Expertise Includes:

• Generator Sizing and Load Prioritization: Backup capacity based on verified building load calculations, so critical equipment stays powered without over or under sizing the system.

• Automatic Transfer Switch (ATS) Design: Transfer switch configurations that shift power automatically and reliably, minimizing downtime when utility service is interrupted.

• Fuel Strategy and Runtime Planning: Fuel type and storage sized for how long your business actually needs to run, not just code minimums.

A generator is only as reliable as the system engineered around it. Our goal is to help you plan for outages before they happen, so backup power performs exactly as expected when it matters most.
