"Energizing the Midwest for over 50 years"















Who are we.......

Clennon Electric, Inc. has been servicing the electrical construction industry for over 50 years.  The Company was established by Howard Clennon on January 8, 1948 when he acquired the former appliance dealership of Frost & Dondanville in Wilmington, IL.  In the early years of the Company, work was based on local electrical service repairs.  Over the years the Company evolved gaining a focus towards commercial and industrial areas of electrical construction.  




Today, Clennon Electric remains family owned with a strong commitment to our community and our customers. Under the leadership of Lawrence Clennon, Howard's son, the Company has representation on the Board of Directors for the Eastern Illinois Chapter of the National Electrical Contractors Association, and as well as several committees of IBEW Local 176.


Clennon Electric is a Union Contractor.  Our electricians are trained at the Joint Apprenticeship Training Center which is sponsored by the National Electrical Contractors Association (NECA) and the International Brotherhood of Electrical Workers (IBEW).  Our electricians are experienced professionals, extensively trained in each of the services we provide.  To remain as a leader of our industry, continuing education is encouraged for all staff. 

Though the Company has grown and evolved to meet the needs of the changing industries, our values and our commitment to helping our clients succeed still remains the focal point of our business.
