Pennsylvania data centers, in short

Pennsylvania has 96 data centers identified from primary sources, spread across 34 cities and counties and run by 42 operators. The largest concentration is Philadelphia, with 17 data centers, followed by Pittsburgh with 17 and Lancaster with 6.

The operators with the most data centers in Pennsylvania are Lumen (6), TierPoint (5), Commonwealth of Pennsylvania (4), Chirisa (4), Web Werks DataCenter Pvt (4). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings.

Not every operator discloses size. In Pennsylvania, 32 publish a floor area and 26 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced.

PJM runs the wholesale power market and the high-voltage grid for all of Pennsylvania. 4 statewide measures governing data centers are on record, alongside 3 local pauses. 8 named projects in Pennsylvania are delayed, blocked or under challenge, and the capital atlas records 2 sites here carrying $20B in announced commitments.
