About Us


In 1971, three partners went into the business of repairing and selling electrical transformers. They sought a central U.S. location and began to canvass the Midwest, particularly Kansas, for a small town in which they could start their shop. The proximity of I-70 for transportation and the broad customer base offered by many rural electric cooperatives and municipalities in Kansas and neighboring states supported the choice of Solomon, Kansas.

In April, Solomon Electrical Supply began operations with owner Gene Hemmer and six employees. We specialized in repairing, remanufacturing and recycling small pole and padmount transformers. Within three years the company’s employment rose to 30 people while it sought to create a market niche with a high-quality transformer product.

With momentum building, in 1980, we added regulators and reclosers to our mix for repair and remanufacture. In 1981, we expanded our power sub facility for repair, rewind, and remanufacture. In 1987, the company found its stride and began to achieve considerable growth in sales. Annual sales reached $3.4 million and the company was at 60 employees and growing. This expansion in the 80s brought a new focus on quality products and exceptional customer service, the building blocks of today’s Solomon Corporation.



In 1991, we opened a new, state-of-the-art transformer reclamation facility in Solomon. This 31,600-square-foot facility alone was more than five times the size of the original Solomon Electric building. We achieved efficiencies through streamlined production capabilities and innovative process development. The addition of transformer reclamation (the recovery of metals from salvaged transformers) provided significant incremental revenue to the company. Metals recovered include copper, aluminum, steel, and brass.

The early 1990s brought three additional major building projects to the manufacturing facilities in Kansas. This increased the quantity of the units manufactured and expanded our capacity to produce power class substation-type transformers.

In January 1996, Solomon expanded east and built a branch facility in Decatur, Tennessee. We developed this initially to funnel product to the Kansas location to ensure continued growth and maintain a competitive edge in a freight-intensive business. Based on customer demand, we expanded this facility and to provide transformer, regulator, and recloser sales and service, as well as reclamation services.



In November 2000, Gene sold controlling interest in the company to his five adult children, all of whom were actively engaged in management and operations of the company. Under the new ownership team, Solomon Corporation continued to grow and improve.

In January 2005, we expanded west by purchasing Western States Recloser Repair in Grand Junction, Colorado. This facility focused on oil circuit recloser and voltage regulator sales and service.

In April 2007, we formed an operational alliance with the Texas Electric Cooperatives for the operation of its repair and reclamation facility in Georgetown, Texas. With this southern expansion, we now had four locations across the U.S. to better serve our expanding customer base. In Kansas that same year, we added a commercial storage permit to our reclamation operation for the processing of electrical oil filled equipment.

In March 2013, we formed a strategic partnership with GFI Energy, ensuring our future expansion and growth. Since 2014, we’ve four additional locations, Grand Junction, Colorado, Prairie du Chien, Wisconsin, Osage City, Kansas and Flandreau, South Dakota, helping us expand our geographical footprint as well as our capabilities. All of which has allowed us to better serve our customers across the country.



Solomon Corporation buys, sells, repairs, recycles, and disposes of transformers, regulators, and reclosers. We are committed to providing unmatched service to our utility and industrial customers. Our engineering support, safety, and environmental records and dedication to delivering quality products have set us apart from the competition for more than 40 years.

Our customers include municipalities, rural electric cooperatives, and investor-owned utilities, as well as industrial users. Solomon Corporation has contracts with some of the largest utilities in the nation, including Oncor, Xcel Energy, Nevada Power, Oklahoma Gas and Electric, Ameren, Georgia Power, Alliant, Centerpoint, and Consumers Energy among others. We employ more than 600 people at our seven locations and have annualized sales exceeding $100,000,000.
