NWI Generator: Powering Northwest Indiana

NWI Generator is a leader in power generator sales, installation, and servicing throughout the Northwest Indiana region. Our service area includes Lake, Porter, and LaPorte counties, as well as counties in Illinois such as Will and Cook. No job is too far or out of the way.

Since 2002, we've shared our expertise far and wide, striving to set each client up with the right generator—so it’s the perfect size and power to negate any electrical outage. We’re licensed, bonded, and insured so you can trust us from start to finish. Not only do we dish out expert installation and servicing left and right, but we take the time to sell you the generator that is the perfect fit for your specific address—whether residential or commercial.

Why Choose NWI Generator?

We are generator specialists.

We focus on backup generators so that we can install, service, and maintain them better than anyone in the region. We work on everything from 7.5kW mini-units to 150kW commercial backup systems. Our technicians are certified to install and repair Generac, Kohler, and Briggs & Stratton generators.

We take quality seriously.

We believe your installation should look great and last as long as your generator – 20+ years. We use copper conductors (not aluminum), steel conduit (not PVC), and pre-cast concrete pads (not plastic). Our sales team will work with you to find the right spot for your generator, and our installation team will make sure it looks great in your landscape.

We make things easy for you.

We want your experience with us to feel convenient and easy. Once you sign your installation proposal, we do all the legwork on permitting, underground utility locations, and scheduling. For ongoing maintenance, we don’t lock you into long prepaid contracts, we just give you a call every year to remind you when its time for maintenance.

We give you peace of mind.

We are a Generac Premier PowerPro dealer and have been in business for over 20 years. We have some of the most experienced technicians in the region, and we are licensed in Indiana, Illinois and Michigan. Lastly, we offer 24/7/365 emergency service so that you’re always covered.


no matter the season...

When the lights go out, you need to protect your family and business from being powerless, and a generator can do just that. Every season poses a risk, especially in Northwest Indiana. A power generator protects your home and business year-round with dependable energy. We offer generators for sale and factory authorized installation and maintenance for standby power all seasons.

No Matter the Day or Time...

Sometimes, there's no avoiding it. In the turbulent weather of the Midwest, a power generator can fail to start up. No matter if your generator was installed by us or not, we're on call to service you—all day, any day. And we're the only ones who can. No other company offers you 24 hour generator servicing. So when your power is down, there's only one number to call.
