16 hyperscale data centersdo not belong on farmlandsurrounded by homes

What is PAX-1?#
A $15 billion campus of 16 data centers: warehouse-sized buildings full of computer servers that run day and night, on farmland in Middlesex Township.
A partnership of Pennsylvania Data Center Partners and PowerHouse Data Centers is building it beside the Conodoguinet Creek, a third of a mile from the Appalachian Trail. 1,333 homes stand within a mile of it.
Construction has started. So have three legal challenges.

Buildings, drives and generator yards drawn from the developer's own plans, the substations and the gravel laydown yard from the fences on its site plans, homes from the county's address records. Aerial imagery: USGS and USDA, taken before construction.

PAX-1 alone will nearly double the industrial land in Middlesex Township.
- Industrial land in Middlesex784 acres
- With PAX-11,478 acres
Most of its sixteen buildings are about 900 feet long and 200 feet wide. Their walls rise about 72 feet, nearly twice the 40-foot limit in the zoning under and around the site. Rooftop penthouses reach about 83.
“The building is two stories.”
What does it mean for me?
It doesn't stop at the property line.#
Power and our bills
9×
the electricity of all homes in Cumberland County
Our grid's independent monitor found data centers added $29.4 billion to the region's capacity costs, the price of keeping enough power plants ready, for June 2025 through May 2029, and PPL says rising capacity prices added about $20 a month to its average home's bill. PAX-1 plans for 1.35 gigawatts more.

Water
146 million
gallons of water allocated a year
The Township's water authority set it aside for the campus, 400,000 gallons a day. Engineers say it equals what 2,367 homes use.
- The water PAX-1 is allocated2,367 homes' worth
- Every home within a mile of it1,333 homes
Generators and air
582
diesel generators
The Clean Air Board told the Supervisors that Cumberland County's air already gets an F from the American Lung Association for short-term particle pollution. The developer's engineer calls testing the generators “a daily activity.”

Noise

Middlesex allows data centers 70 decibels at the property line. To protect sleep, the World Health Organization advises no more than 45 outside homes at night.

The state found PAX-1 will have an adverse effect on the Trail. The Trail Conservancy counts upwards of 150,000 visitors to this part of the Trail each year.

the area the stormwater permit first covered, from 36 acres for 58 homes to 693 acres now
In Middlesex, a warehouse needs a public hearing. A hyperscale data center does not.
“We changed the ordinance. Unfortunately, there's really nothing the board of supervisors can do to stop this project.”

Can it still be stopped?
They haven't won yet.#
Yes, bulldozers are rolling, but that doesn't make it legal, and it doesn't make it final. We see significant issues with how this was approved, and we are challenging them in every way we can.
Zoning drawn for the developer's land, and nowhere else.

Why does it matter beyond Middlesex?
If it can happen here, it can happen next to you.#
The companies behind PAX-1 are already looking at other townships.
Monroe Township, Cumberland County
144 acres
secured by the partnership behind PAX-1, which asked in April 2026 to present plans for another data center there
Granville Township, Mifflin County
6 buildings
filed for in July 2026 by one of the companies behind PAX-1, two days before a planned pause on data centers there
10 other data centers, Monroe and Granville among them, are in the works within 60 miles of Middlesex.
- PAX-1
- Proposed or under review
- Paused or withdrawn after residents pushed back
Each township still writes its own rules. Statewide, the Governor wrote in August 2026 that most proposed data centers are “speculative in nature, with no identified end user.”
