A Senate advanced Coleman/Walsh bill would let PA towns pause massive AI and cloud data centers and unwind a 2021 tax break worth about $2B in lost revenue by 2031. SB 939 (Rothman) runs the other way.
A state Senate-advanced bill from Sen. Jarrett Coleman (R-Bucks/Lehigh) and Sen. Walsh would let Pennsylvania municipalities pause hyperscale data center development for 18 months and unwind a 2021 sales-and-use-tax exemption for data-center equipment. A separate live bill, SB 939 from Sen. Rothman (R-District 34), would invite large technology companies to pilot AI systems in Pennsylvania with pared-back environmental review and expedited approval.
The two tracks do not reconcile on the same footprint.
A hyperscale data center is a multi-hundred-megawatt building, usually 500,000 to 1.5 million square feet, that hosts AI training clusters or cloud capacity for a small number of large tenants. It draws a town-scale slice of the local grid and water supply. The 2021 Pennsylvania sales-and-use-tax exemption taxes data-center servers, switches, and cooling gear at zero percent. Coleman wants to take that exemption back.
The Coleman/Walsh push is a slowdown lever. In May, the two senators said they wanted to "combat data center spread" and give Pennsylvania towns explicit authority to halt new hyperscale projects while grid and water impacts were assessed (senatorcoleman.com). In April, Coleman called for a moratorium on data centers in his eastern Pennsylvania district (lehighvalleylive.com). In July, the state Senate advanced the 18-month municipal-pause language (Broadband Breakfast). A lehighvalleylive.com analysis pegs the cost of repealing the 2021 sales-and-use-tax exemption at roughly $2 billion in lost state revenue by 2031 (lehighvalleylive.com).
SB 939 runs the other direction. The bill, tracked by PennFuture's data-center legislation tracker, would create an AI-pilot pathway with "minimal oversight" and "fast-tracked environmental review," the regulatory short-cut hyperscale operators ask for when they want a state to host training or inference infrastructure (PennFuture Data Center Legislation Tracker). The pilot lane is built for speed. The moratorium lane is built for pause.
The collision is concrete. Hyperscale data centers and AI training clusters are increasingly the same physical object: the same concrete pad, the same multi-hundred-megawatt interconnect, the same water-cooling loop. A moratorium that targets "data-center spread" by definition reaches the same build that an AI-pilot lane is meant to attract. Pennsylvania is now building, in parallel, a lever to slow the footprint and a lever to fast-track the same footprint, with no reconciliation clause in either bill on the public record.
The politics cut across the tracks inside the state GOP. Coleman and Walsh are advancing the local-control and revenue-restoration argument. Rothman is advancing the job-creation and AI-competitiveness argument. All three are Republicans. Both bills are live. There is no committee-level signal that one is meant to swallow the other, and neither has reached the House floor.
For Pennsylvania readers, the watch items for the next General Assembly session are: whether the moratorium keeps its 18-month municipal-pause language, whether the tax-repeal language is bundled into the same bill or held back, and whether SB 939's AI-pilot carve-outs are narrowed enough to live inside a future data-center siting regime, or left wide enough to undercut one.
The Face the State episode that aired Sunday on WHP/CBS21 Harrisburg grouped the data-center fight with two other statehouse threads (Flock automated license-plate-reader cameras, and the Fetterman-McCormick relationship) under one segment (local21news.com). Of the three, the data-center collision is the only one with a real, dated peg.
