We don't pull numbers out of thin air. The estimate combines facility-size norms with the energy reduction our licensed installer partners actually achieve and the published rebate structures of Michigan's two major utilities.
Energy reduction
We model 60%+ lighting energy reduction — grounded in the 63–67% average our licensed installer partners report across hundreds of completed Michigan commercial projects.
Rebate range
DTE and Consumers Energy both pay prescriptive commercial-lighting rebates. We apply typical per-square-foot ranges for your facility size and current lighting type.
Net investment & payback
We net the rebate against project cost to show your real out-of-pocket number, then divide by annual savings. Most Michigan commercial retrofits land near a ~24-month payback — and with Stellux's low-cost financing, the savings can cover the payment from month one.
Honest disclaimer: Zumergy is a Michigan energy demand brand — we are not a licensed electrical contractor and we do not file your rebate. This tool estimates your opportunity and routes qualified projects to our licensed Michigan installer partners (for lighting, typically Stellux, a DTE/Consumers Energy trade ally), who confirm the numbers, file the rebate paperwork, and perform the installation.

Frequently asked questions
How accurate is the estimate?
It's a planning-grade estimate, not a quote. The calculator uses typical Michigan commercial figures — roughly 60%+ lighting energy reduction (our licensed installer partners average 63–67%), typical per-square-foot project costs, DTE/Consumers Energy prescriptive rebate ranges, and a payback of about two years — applied to the facility size and lighting type you enter. Your real numbers depend on your fixtures, run hours, and electric rate, which is exactly what the free on-site assessment from a licensed installer partner pins down.
Can I cover the project cost out of the savings?
Often, yes. Stellux, our primary Michigan lighting installer partner, offers low-cost financing on commercial LED retrofits. Because the energy savings frequently exceed the monthly financing payment, many projects are cash-flow-positive from month one — the upgrade can pay for itself while you keep cash in the bank. The calculator shows your estimated net investment after rebate; a licensed installer can structure financing around it.
What happens after I submit my details?
Zumergy reviews your facility details and routes them to one of our licensed Michigan installer partners — for lighting in DTE and Consumers Energy territory, that's typically Stellux, a DTE and Consumers Energy trade ally. They follow up to confirm your numbers, walk the site if needed, and prepare a precise rebate and savings figure. There's no cost and no obligation to proceed.
Is the calculator and assessment free?
Yes. The calculator is free, and the follow-up facility assessment from our licensed installer partners is free with no obligation. Zumergy is paid by its installer partners on a documented lead/commission basis only if a project moves forward — you're never billed.
Who actually does the rebate paperwork and the installation?
Our licensed Michigan installer partners do. Zumergy is a demand and referral brand — we are not a licensed electrical contractor and we don't file rebates. We estimate your opportunity and connect you with a licensed installer that's a DTE/Consumers Energy trade ally, who handles the rebate application and the installation.
