Powergrid Solutions

Powergrid Solutions Inc. is now part of AZZ Inc.!

On Wednesday, September 6th, AZZ Inc acquired Powergrid Solutions (PSI).  The company designs, engineers and manufactures low and medium-voltage power quality, power generation and distribution equipment. PSI is located in Oshkosh, Wisconsin; our business was started in 1982 as Shallbetter, Inc. In 2015 the name was changed to Powergrid Solutions Inc. (PSI) to embrace the wide diversity of products the company produces. Those products range from simple pad-mounted equipment, to 35kV metal-clad switchgear reaching 100' in length.

PSI focuses its operations around five key core values; Customization, Flexibility, Quality, Value, Service. While other companies sell what they manufacture, PSI manufactures what the customer purchases which results in accurately meeting the customers exact needs.
