PAX-1 Data Center

PAX-1 is an advancing Middlesex Township project with official developer disclosures about water planning, power infrastructure, and construction/community commitments. Those disclosures improve project-service provenance but do not establish measured water use, energized capacity, or data-center IT load.

Compute Workload

This panel tracks what the facility is for without assuming that every project is AI training, inference, or cloud capacity.

Undisclosed / unknownUnknown

No source-backed workload, customer, hardware, or training/inference allocation is attached to this record yet.

Workload classification remains unknown in the reviewed record.

Water

PAX-1's official project site says MTMA reviewed and approved water plans for up to 400,000 gallons per day, with evaporative cooling during peak thermal conditions. It says no cooling or process water will be discharged to Conodoguinet Creek; the reviewed public material does not establish measured operating use or final permit conditions.

Power

PAX-1's official project site says PPL is planning a new switchyard and 500 kV transmission lines and describes a $250 million developer-paid infrastructure investment. The dataset's 1,350-1,800 MW remains planned campus/project context, not confirmed energized or IT-load capacity.
