Illinois turned the who-pays question into a state instrument. Governor J.B. Pritzker's two-year suspension of new data-center tax incentives took effect July 1, directing the state's economic-development office to halt breaks that had stood since 2019 after lawmakers failed to pass comprehensive reform. [1] The paper's July 7 account of how Illinois suspended its data-center tax breaks established the freeze and the dollar figures behind it. Today those figures are the point: Illinois is the clearest state-level "who pays for AI power" instrument yet, and it should be read against the federal gap it fills.

The dollar receipt is explicit. Within PJM's 13-state grid, data-center demand has already raised costs by roughly $13 billion, and could add about $37 billion more in Illinois alone. [2] Pritzker paired the freeze with a demand on PJM: that data centers bring their own generation or face emergency curtailment, and that the grid operator "keep consumers at the center of every decision." [3] He also asked the legislature to ban the nondisclosure agreements that have kept data-center deals secret from the communities hosting them. [3]

This is a state instrument with a dollar figure attached, not a proposal. That distinction is what separates it from the federal record. The Department of Energy's emergency curtailment authority — the 202(c) orders that could route large loads off the grid during the heat — lapsed on July 7 with no permanent successor, and FERC's large-load docket does not produce binding cost-allocation until an August 17 filing deadline at the earliest. Into that vacuum, states are legislating one leg at a time: tax in Illinois, power in the PJM and FERC dockets, water in state disclosure laws. The household-visible cost of AI power is being decided state by state because no binding federal instrument answers it.

On X, the freeze splits cleanly — overdue justice against data centers dumping their power bill on households, or anti-growth sabotage that will push campuses to friendlier states. MSM reads it as economic-development policy that risks steering data centers elsewhere in the region. [1] The paper's middle is the arithmetic: a freeze plus a $13-billion-and-counting cost figure makes Illinois a measurable who-pays instrument, and the open risk is geographic — that data centers respond by siting elsewhere in PJM, exporting the cost rather than shrinking it. Whether the veto-session reform passes or the two-year freeze stands alone is the next receipt.
