AI Data Centers in Pennsylvania: Tracked Sites (2026)

Pennsylvania is home to three major tracked artificial intelligence (AI) data center facilities, representing at least 1,920 megawatts (MW) of tracked electrical capacity, with the capacity of a third facility not yet disclosed. Ban the Bots' data center map monitors hyperscale and AI infrastructure across the Mid-Atlantic region. Pennsylvania is the only state on this site's tracker where a data center campus is co-located directly with a nuclear power plant. This 1,920 MW tracked footprint places Pennsylvania below national infrastructure leaders such as Virginia with its tracked 8,300+ MW capacity, Wisconsin at roughly 5,320 MW, and Texas with over 4,500 MW, while exceeding smaller hubs such as Oregon at 1,150 MW.

Which Companies Operate AI Data Centers in Pennsylvania?

A single technology company operates all three tracked hyperscale facilities in the state: Amazon Web Services (AWS). Amazon Web Services has concentrated its capital deployment in Pennsylvania through a multi-billion dollar expansion program. This infrastructure investment forms part of an overall 20 billion dollar commitment by Amazon to develop digital infrastructure across the Commonwealth.

Amazon Web Services selected two distinct geographic environments within Pennsylvania for these massive server deployments. In eastern Pennsylvania, Amazon Web Services placed an industrial redevelopment campus in Bucks County close to metropolitan population centers. Amazon Web Services placed two more facilities near existing nuclear power generation assets within Luzerne County and Columbia County.

By focusing its Pennsylvania capital commitments entirely under a single corporate umbrella, Amazon Web Services has sought to secure long-term power delivery for high-density computing clusters. Each site serves critical roles within the broader cloud computing and machine learning infrastructure network maintained by Amazon Web Services.

Why Pennsylvania Attracted Nuclear Co-Location Infrastructure

Pennsylvania became a focus for hyperscale computing development because of access to existing baseload nuclear power. The Susquehanna Steam Electric Station nuclear plant provided the draw for two of Amazon Web Services' three tracked Pennsylvania sites: the Berwick proposal signed a deal to buy power directly from the plant, and the Salem Township campus sits on a former nuclear-adjacent site with co-located cooling infrastructure.

The third site, Falls Township, took a different path: a 2 million square foot campus built on the former U.S. Steel Keystone Trade Center property in Bucks County, developed as a grid-powered site rather than a nuclear co-location.

Regulatory Scrutiny and the April 2025 FERC Decision

Direct electrical connections between data centers and nuclear generation stations have triggered regulatory intervention. In April 2025, the Federal Energy Regulatory Commission (FERC) blocked the specific colocation agreement for direct power supply between the Susquehanna Steam Electric Station and the adjacent data center development, citing grid reliability and fairness concerns.

Power consumption and regional utility impacts remain central points of debate across all three Pennsylvania campuses. Readers can evaluate broader grid strain and utility demands using Ban the Bots' guide on AI data center environmental impact or calculate facility cooling volumes with the AI water use calculator.

Pennsylvania AI Data Center Facilities, One by One

• AWS AI Innovation Campus: Salem Township (Salem Township, Luzerne County; under construction): This facility comprises 15 data center buildings situated on the former Cumulus Data nuclear-adjacent campus following a 650 million dollar campus acquisition. The campus has a tracked capacity of 960 MW, which ramps up in 120 MW increments. The site was designed to draw cooling water directly through the co-located water infrastructure of the adjacent Susquehanna Steam Electric Station. The direct power supply arrangement was blocked by the Federal Energy Regulatory Commission in April 2025. Development status is documented through the Pennsylvania Governor's Fast Track project filing.
• AWS AI Innovation Campus: Falls Township (Falls Township, Bucks County; under construction): A 2 million square foot digital infrastructure campus located on the former U.S. Steel Keystone Trade Center property. The facility is being developed as a grid-powered site with no on-site generation noted. Its total electrical capacity and water source are not specified in current tracking data. This project is part of Amazon's broader 20 billion dollar Pennsylvania commitment. Development details are reported by Construction Dive's capital investment report.
• Amazon Web Services Proposed Nuclear-Powered Campus (Berwick, Columbia County; proposed): Originally announced in March 2023, this proposed facility has a tracked capacity of 960 MW. The facility plans to draw cooling water from the Susquehanna River via the Susquehanna Steam Electric Station. Amazon Web Services signed an agreement to purchase electrical power directly from the adjacent nuclear power plant, which prompted regional debate regarding nuclear co-location. Regulators under the Federal Energy Regulatory Commission raised safety and grid-fairness concerns regarding the proposed direct-connection arrangement. The initial transaction is documented by The Washington Post's reporting on the nuclear power agreement.

FAQ: AI Data Centers in Pennsylvania

How many AI data centers are in Pennsylvania?

Ban the Bots tracks three major AI data center facilities in Pennsylvania as of 2026. These comprise two campuses currently under construction and one proposed development. Two of the three sites account for a combined 1,920 megawatts of tracked capacity, while the capacity for the third facility is not yet publicly disclosed.

Where are Pennsylvania's AI data centers located?

Pennsylvania's tracked AI data centers are located in Luzerne County, Columbia County, and Bucks County. Amazon Web Services is developing two nuclear-adjacent projects in Salem Township and Berwick along the Susquehanna River. The third project is an industrial redevelopment campus situated in Falls Township on the former U.S. Steel property.

Why did FERC block Amazon's nuclear data center deal in Pennsylvania?

The Federal Energy Regulatory Commission blocked the direct power supply arrangement in April 2025 due to concerns over electrical grid reliability and cost fairness. Regulators evaluated whether allowing a data center to draw power directly from the Susquehanna Steam Electric Station behind the meter would shift electrical transmission costs onto regular utility ratepayers and weaken regional power availability.

How much power do Pennsylvania's AI data centers use?

The tracked Pennsylvania AI data center campuses represent at least 1,920 megawatts of combined electrical capacity. The Salem Township development accounts for 960 megawatts ramping in 120 megawatt increments, and the proposed Berwick project accounts for another 960 megawatts. The electrical capacity for the Falls Township development is not specified in current tracking data.

Tracking Pennsylvania's AI Data Center Footprint

Pennsylvania's at least 1,920 megawatts of tracked capacity demonstrate how hyperscale operators have attempted to pair massive computing loads directly with baseload nuclear generation. The state remains a primary focal point for federal regulatory decisions governing grid connections and regional energy reliability.
