About Denny's Electric LLC

Denny’s Electric played a vital role during the oil boom of the ’80s, when we specialized in industrial and service work that propelled North Dakota’s flourishing energy economy forward. In the ’90s we expanded our services to include residential, commercial and agricultural work, as well as generator sales and electric motor repair for a wide range of industries. By 2020, we had already expanded to serve the majority of southwest North Dakota.

Denny laid the foundation for the success our team enjoys today. We remain committed to providing high-quality electrical solutions, no matter the nature or scale of our client’s needs. Our high-tech tools, cutting-edge techniques, safe practices, and commitment to building strong relationships with our clients has made – and will continue to make – Denny’s the top name in North Dakota electrical contractors.

We are fortunate to contribute to the world like we do. Whether we’re automating your home, installing new equipment at your business, upgrading a control system in your production facility, servicing the irrigation system at your farm, or assisting with your municipal improvement project, we will treat your project like what it truly is: an opportunity to improve our community, one inch of wire at a time. We’re also proud to give back to our community in ways that don’t involve electrical work.

About Denny's Electric LLC

How It Works HSB

Generator Installation

WHAT'S INVOLVED IN INSTALLING A HOME BACKUP GENERATOR?

Installing a home backup generator is an exciting time. Denny's Electric LLC will prepare the installation site outside your home, place the generator, run the natural gas or LP fuel line, install the transfer switch, and make all of the necessary electrical connections. And we will make sure that your backup generator runs properly, and is ready for its first power outage.

Generator Repair & Warranty

You invested in a Generac automatic home backup generator, and now you're never without power. But just like a car, air-cooled backup generators need to be properly maintained to perform as intended. We recommend you have your unit serviced every 6 months. Our factory-trained technicians are available to handle all your Generac servicing needs.

If you are looking for the Owner's Manual for your generator (or any other Generac equipment), please use the online product support on the Generac.com website. You can use your model number or serial number to find your manual by using the form located here:

For questions about the warranty of your Generac generator (or other Generac equipment), please contact Generac directly at 888-GENERAC (888-436-3722)

To ensure accurate warranty coverage, please make sure your Generac equipment is registered at

An added benefit of registering is proof-of-purchase in the event of an insurance loss such as fire, flood or theft.
