For six months now, Wisconsin Watch has made a concerted effort to report on data centers. We’re publishing major stories at WisconsinWatch.org and, each Monday, we provide data center news nuggets in our Forward newsletter (subscribe here).

Here’s a month-by-month summary of what we’ve reported.

January: Wisconsin Watch revealed that officials in at least four Wisconsin communities (the number has since grown) signed nondisclosure agreements that hid details of billion-dollar data center proposals from the public.

February: We detailed how a $1 billion data center is being proposed for Grant County in the Driftless Area of southwest Wisconsin.

March: In a sign of the impact of artificial intelligence data centers, we reported that just three Wisconsin companies have done more than $1 billion in business supplying the facilities. We also disclosed more NDAs and other ways local governments have tried to keep data center details secret.

April: We were the first to report on an official estimate that state government will forgo $2 billion in revenue because of a sales tax exemption for data centers that was adopted in 2023.

June: We spent months gathering behind-the-scenes details on what happened to the Driftless Area proposal.

July: We detailed how land sales for the data center under construction in Port Washington turned homeowners and farmers into millionaires and, in some cases, created generation-changing wealth.

More stories are in the works.
