There’s nothing like a common enemy to bring people together. This midterm election year, that enemy may be data centers.

As AI grows more powerful and more popular, tech companies are rushing to build facilities that house all that computing capability — and to secure tons of power to run them. But no one knows exactly how many of those data centers will get constructed, and how much electricity they’ll need. That’s a problem for utility customers, who may be saddled with the costs and climate impacts of an unnecessary gas power and grid infrastructure buildout.

Some states are tackling the problem with what are known as large-load tariffs: essentially, special rates and requirements that force big power users to shoulder the costs of grid buildouts. But this week, a small city in Wisconsin put its foot down. Port Washington, a suburb of Milwaukee, voted by a roughly 2-to-1 margin to require that city leaders get voter approval before awarding tax breaks to data centers and other large development projects. It’s a clear response to the $15 billion OpenAI and Oracle megaproject that’s being built in the city, though this newly approved measure comes too late to affect that project.

At the federal level, Democrats have spearheaded most of the campaigns against data centers, with Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.) even proposing a nationwide moratorium. But Port Washington is part of Ozaukee County, which has voted for Republicans over the past 20-plus years of elections.
