AWS Salem Township campus (Susquehanna nuclear plant) Under construction
One of two initial sites in Amazon's announced $20B+ Pennsylvania data-center investment: a campus alongside the Susquehanna Steam Electric Station nuclear plant, where majority owner Talen Energy agreed to supply 960 MW. The original behind-the-meter connection drew FERC scrutiny and was blocked in 2024. The 960 MW figure is the contracted power supply, not built capacity.

A working set of identified proposals a community can track, not a census — most of the country's activity is not in here yet. Pennsylvania is the exception: its rows are synced from PA DEP's own data-center permit tracker, so the state's coverage is close to complete and carries the permit trail with it. **Each row carries its own provenance.** Rows showing a verification date link to reporting or the governing body's own record and were read on that date; rows marked *unverified* have no source on record — a lead to check, not a fact to cite. **Stage is derived, not asserted.** *Hearing scheduled*, *Awaiting decision*, *Approved* and *Withdrawn* are computed from each row's milestone dates on every rebuild, so a hearing date that has passed stops reading 'scheduled'. Hearings get moved and projects re-file under new names — treat a scheduled date as the earliest to act by, and confirm with the clerk before relying on it. Leads are mined into data/project_candidates.json and promoted here only after a human reads a primary source.
