QTS is planning a large-scale data center campus in the town of Vienna, Dane County, Wisconsin. The proposed site spans 615 acres and could eventually host up to 15 buildings, with an initial phase targeting three to five facilities. This development represents a potential $3 billion investment and is strategically positioned near Highway V, west of DeForest, with support from Alliant Energy to meet power demands.
The campus is expected to generate significant economic benefits, including 450 permanent jobs and thousands of construction roles. QTS emphasizes sustainability through water-free cooling systems that save over 48 million gallons annually per data center, and the company aims to meet LEED and Energy Star standards. Environmental studies and tree replacement programs are part of their mitigation efforts to preserve local ecosystems.
Community engagement is central to QTS’ approach, with public meetings and partnerships with local universities to support agricultural research and workforce development. The company also promotes local prosperity through charitable programs, internships, and collaboration with regional suppliers. Their goal is to create a long-term technology ecosystem that benefits both the local economy and environment.
This is a campus listing, that covers multiple data centers.
