Alliant Energy Growth Sites

Alliant Energy’s certified industrial sites initiative parallels a typical site location process. If your firm is seeking a site for a data center, a large rail-served manufacturing operation, bio processing venture, or a food processing facility, our sites have been vetted on many critical “must-have” factors for that specific industry sector.

Our site certification program is performed in the spirit of full disclosure by delving into the property in detail by requiring environmental clearance; a Phase-I Environmental Site Assessment, endangered species study, archaeological survey, wetland delineation study, a preliminary subsurface investigation (i.e. soil borings), zoning restrictions evaluation, title work, utility infrastructure assessment and engineered plans.

Our certified sites will provide a company or a site location consultant with the information they need to make a determination about whether the site is a good fit for their specific project.
