Why Every Chicago Business Needs Commercial Backup Generators

Blackouts happen fast in Chicago. Ice storms, aging infrastructure, and grid overloads hit harder here. Without power, you lose customers, productivity, and money.

That’s why commercial backup generators are a smart move—they keep your lights on and your business open.

Commercial Generator Installation Services

Generator Sizing, Brands & Custom Installation

We start with a full load assessment to get the commercial generator sizing right. Too small and your system fails. Too big and you waste money. We install Generac commercial generators, Kohler commercial generators, and more, based on what fits your needs. Whether it’s a generator for a commercial building or multiple large commercial generators, we handle it.

Automatic Transfer Switches & Seamless Integration

Our systems include automatic transfer switches for instant power transfer. That means no downtime, no confusion—just business as usual. We install new systems or retrofit into existing setups, always meeting code. Our goal is seamless power when the grid goes down.

Permitting, Code Compliance & Inspections

We manage every permit, inspection, and city requirement. No missed steps. No delays. Our licensed team works directly with Chicago’s inspectors so your commercial generator installation goes live without issues. We make it easy from start to finish.

Eddie and his team, John and Enrique, provided outstanding electrical service. From the initial contact to the completion of the job, they were a pleasure to work with. Their professionalism was evident in every interaction. They were polite, courteous, and respectful of my home. What truly sets Eddie and his team apart was their ability to clearly explain the issues and provide multiple options for solutions. They took the time to ensure I understood the work that needed to be done and the various approaches we could take. This level of transparency and communication was greatly appreciated. They arrive on time and their estimates are accurate. The quality of their work is excellent, and they completed the job efficiently and cleanly. I feel confident in their expertise and trust their recommendations. I highly recommend Eddie and his team for any electrical needs. They are a reliable, professional, and knowledgeable team that provides top-notch service.

Eddie was great. He educated me on my electrical issue and was quick and thorough. All of this was done while training a new employee. I will be contacting Mr.Mighty Electric for my future needs.

Eddie Morales Jr was the electrician sent by Mr Mighty Electric. He is fantastic! Very capable and polite. Super honest as well. He identified the problem as minor and quickly fixed it. The day before another electrician had proposed major and expensive repairs to fix the same issue.
