About Kilowatt Electric

Kilowatt Electric provides complete residential electric and commercial electrical services to the Rapid City, SD area. We’ve been proudly serving the Black Hills area since 1982, when it was established by Mark Beshara. After establishing Kilowatt Electric in 1982, Mark Beshara worked steadily to build a solid reputation as a business that provided quality work at affordable prices. On December 30, 2013, Mr. Beshara sold the business to Jared Wilhelmi, an employee of thirteen years, and his son, Tony Beshara, and Kilowatt Electric became TruPower, Inc., DBA Kilowatt Electric. Jared and Tony’s mission is to carry this reputation forward as a quality provider of electrical services. 

The success of any business depends on having highly qualified professional employees. Kilowatt Electric started with a small team of seventeen in 2013. Today, in 2025, that team has grown to roughly 30 employees, continuing to power success in every project.

Currently, our team includes apprentice electricians, project foremen, and journeyman electricians who handle field work and services. The rest of our talented staff in management and administration ensures everything runs smoothly, making us a strong, well-rounded team.

We work hard to ensure that we find qualified, dedicated employees to provide our customers the best service possible. 

Today we work on projects ranging from house calls to million-dollar industrial projects. With three main divisions; Services Call, Commercial, and Residential projects; we can handle any job that comes our way. Our specialties include design build services, commercial wiring, data network installation, energy management systems installation, lighting installation, and residential wiring. You can count on our business practices as we are Better Business Bureau certified with an A+ rating. Just take a look at our profile!
