What the source record says
'Pennsylvania Digital I' (PAX) in Carlisle, Cumberland County: a ~700-acre, three-campus development delivering 1.35 GW (expandable to 1.8 GW — in notes), each campus with six buildings and a 450 MW substation. The $15B is the project value across all three campuses (in notes). 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 -> investmentUsd omitted. Pennsylvania's data-center sales-tax exemption eligibility is likely but no confirmed award or LERTA designation was found. Partner: Pennsylvania Data Center Partners.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
