What Happened?

Your electricity bill and local water supply could be affected by a wave of massive computer facilities being built across the country, and Congress is now weighing whether to step in. A report published Sept. 3 by the Congressional Research Service (CRS), the nonpartisan agency that does research for Congress, lays out the legal tools lawmakers could use to regulate AI data centers, the warehouse-sized facilities that power artificial intelligence services.

The report comes as large tech companies race to build these facilities at a scale that strains local power grids and water systems, drawing opposition from some communities and prompting calls for tighter rules.

Why Does it Matter to Me?

Data centers that support AI consume large amounts of electricity and water. When demand spikes, those costs can ripple through to your utility bill. Some proposed bills in the current Congress would require state regulators to certify, before receiving certain federal energy grants, that their electricity rates for everyday customers and small businesses do not reflect the cost of meeting data centers' electricity demand.

That means Congress is considering rules that would stop data center energy costs from being passed on to households. Other proposals would push data centers to find their own water sources rather than drawing from local utilities.

Both Sides, Now

The CRS report identifies three constitutional tools Congress could use:

  • The Commerce Clause, which lets Congress regulate interstate commerce. Because courts have broadly held that the internet is a channel of interstate commerce, and data centers are essential to the internet, Congress may have authority to regulate their design, location, and operation. No court has directly ruled on this yet.
  • The Taxing Power, which Congress could use to penalize certain practices or reward others. Proposed bills would tax electricity that data centers consume or strip tax benefits from facilities that don't meet environmental standards or community agreements.
  • The Spending Power, which lets Congress attach conditions to federal grant money. States that want certain energy funds could be required to follow rules protecting residential ratepayers.

Supporters of federal rules argue that the scale of AI infrastructure has outgrown state and local oversight. Opponents, including those who favor local control, can point to a legal limit called the anti-commandeering doctrine, which bars Congress from ordering state officials to carry out federal policy directly. The Supreme Court has also ruled that federal funding conditions cannot be so coercive that states have no real choice but to comply.

Congress could also choose a middle path, setting minimum national standards while letting states go further, a model used in the Clean Air Act and Clean Water Act.

What Happens Next?

Several bills in the current Congress, known as the 119th Congress, already propose specific rules, including barring new AI data center construction, requiring off-grid power sources, and redirecting water use. None of those bills has become law. For any of these proposals to take effect, a bill would need to pass both the House and Senate and be signed by the president. The CRS report maps the legal landscape but does not itself create any rules. Congress holds the power to act, and the report gives lawmakers a clearer picture of what the Constitution allows.
