E11: Building India’s Digital Backbone with Sharad Agarwal
Mar 12, 2026 Eric Bell World
Go to PodcastEpic Systems runs its primary data center underground on its Verona campus, southwest of Madison. It opened in early 2015 for Epic Hosting, which runs electronic health records for Epic's client health systems. Epic built the facility to withstand an F4 tornado, and the campus generator plant can power the whole campus for two weeks. Geothermal heat pumps help cool the data center.
In 2024 the State of Wisconsin certified Epic Hosting's Utility Building #3 project on the campus as a qualified data center for the state sales tax exemption. The project is a $347 million investment.
