   Underlying source

Source notes

'Pennsylvania Digital I' (PAX) in Carlisle, Cumberland County: a ~700-acre, three-campus development delivering 1.35 GW (expandable to 1.8 GW), each campus with six buildings and a 450 MW substation. The $15B is the project value across all three campuses. Near-term 300 MW by Q2 2027. Coordinates are the Carlisle area centroid. The $15B figure is the three-campus JV total, not broken out per campus -> no investment figure is recorded. Pennsylvania's data-center sales-tax exemption eligibility is likely but no confirmed award or LERTA designation was found. Partner: Pennsylvania Data Center Partners.

PPL Electric Utilities will connect the campuses via a new 500 kV-138 kV switching station; 1.35 GW delivered via the PJM grid. No on-site generation confirmed.
