About Powergrid

Most companies sell what they manufacture, we manufacture to customer's specific needs

Design, build, and deliver

Located in Oshkosh, Wisconsin, our business started in 1982 as Shallbetter, Inc. In 2015, the name changed to Powergrid Solutions Inc. (PSI) to embrace the vast diversity of products the company produces. Those products range from metal-enclosed capacitor banks to 35kV metal-clad switchgear reaching 100′ in length.

In 2006, the company built a new office and manufacturing facility to provide much-needed space for handling increased growth and larger projects. Our location in Oshkosh’s Northwest Industrial Park offers fast access to the interstate highway system, rail systems, and international airports. Milwaukee, Chicago, and Minneapolis are all within driving distance, while the Fox Valley area is home to various engineered products and specialty metal manufacturing.


Designed specifically to accommodate Powergrid Solutions’ fully-integrated manufacturing process, our 50,000 square-foot office and manufacturing facility in Oshkosh, WI, was custom-built to maintain diversity in products and flexibility.

While other companies sell what they manufacture, we manufacture to customers’ specific needs. Our business model is built for customization and flexibility. We do the entire process: engineer the product, fabricate it (including cut, punch, bend, weld, and paint), assemble and test each cabinet.

Powergrid Solutions’ business model focuses on five core values. Instilled in every product we produce, these values continue to differentiate PSI from other manufacturers


With our customization capabilities and flexible, integrated manufacturing process, we develop products that meet your specific needs.


Powergrid Solutions’ integrated manufacturing process provides the flexibility to manufacture a full range of products, from empty enclosures to complex power distribution and generation solutions. Our flexibility extends to components, giving you the ability to choose from a variety of manufacturers.


Powergrid Solutions’ commitment to quality begins with high-grade materials: Mild steel, A-60 galvanneal steel, aluminum or stainless steel enclosures, stainless steel external hardware, and industry-standard paint. The commitment continues in our quality construction process. Testing is at the core of our meticulous Quality Control System, which ensures PSI equipment is installation-ready upon delivery. Our commitment to quality translates into long-term value for you.


PSI solutions are developed with your bottom line in mind. Whether you choose a custom design or an off-the shelf model, the life cycle of PSI products, ease of installation and customization options make them a great value.


Powergrid Solutions’ customer care is second to none. From conceptualization to installation, our electrical-mechanical designers, application engineers, on-site service, and start-up support are focused on energizing your company.
