What is established
Partially operational. 960 MW announced (gross site power); owned or developed by Amazon Web Services.
What is not disclosed
Accelerator count, hardware platform, project capex, timeline, named tenant, power source, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
Former Talen Cumulus campus adjacent to the Susquehanna nuclear plant, bought for $650M in Mar 2024 with ~240 MW developed at acquisition; ramping toward up to 960 MW site power. The 2025 Talen PPA covers up to 1,920 MW across AWS Pennsylvania sites. No source states the currently energized level, so nothing is recorded as confirmed.
Corroborated by more than one source, but not yet backed by physical evidence.
Power readiness
Capacity basis stated
The source distinguishes IT load from total site power or on-site generation.
