Founded in 1996 by Wayne E Williams, ISI is one of the few regional companies located in the Midwest that offers Developers nationwide the full EPC package for renewable solar energy and Battery Energy Storage System (BESS.) 

ISI is people. The organization was built and continues to be built with solid character individuals who have demonstrated expertise in their field. Our people and value system come first. Happy team members perpetuate the values that ISI holds dear. We strive for excellence through training and communication.

We practice all the concepts of LEAN construction. Plan your work – Work your plan safely. It is that simple. There is colleague buy-in throughout the organization with Best Practice and Lessons Learned and the forefront of every decision. We pool our knowledge through coordinated meetings and promote knowledge transfer from department to department horizontally and vertically. We’ve adopted the practical concept that None of us is as smart as all of us.

Communication and transparency with our customer is paramount. Our customers have the unique advantage to login to see into our individual projects through access of our Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) software. Customers see anything from schedule updates and daily progress photos to that morning’s Job Hazard Analysis (JHA) that was discussed at the morning safety meeting.

Integrity is principal. Always tell the truth. This is a concept that is driven into all thought processes throughout the ranks whether it is Engineering, Procurement, or Construction. If trust is not the foundation of a relationship, there is no relationship. We would encourage anyone looking at ISI for an EPC consideration to visit our testimony page. There are a lot of big-name recognition companies that use ISI as a trusted Source. Ask them.
