Under construction in Lancaster City, Lancaster County

The number that mattersThe project is sized at about 300 megawatts.

Current stage: Announced July 2025 with financing closed and a builder selected.
Decision body: Lancaster City
Top issues: Residents and officials have focused on electricity demand and grid capacity, what remains in the ground from the site's industrial past, water use, continuous mechanical noise, and emissions from backup generation.

Chirisa Technology Parks + Machine Investment Group (developers); CoreWeave sole tenant (NASDAQ: CRWV). 5 data halls. Air-cooled (NO water for cooling). Two on-site substations + PPL switchyard upgrade. GC: Turner-Wohlsen JV. PA DEP draft air permit (emergency diesels) in PA Bulletin Nov 15 2025. City zoning amendment adopted Dec 2025/early 2026. Community-benefits agreement under negotiation with Mayor Danene Sorace. CoreWeave announced more than $6 billion for a purpose-built AI data center in Lancaster on July 15, 2025 at Sen. Dave McCormick's Pennsylvania Energy and Innovation Summit at Carnegie Mellon, during a CEO roundtable with President Trump. The site at 216 Greenfield Road and 1375 Harrisburg Pike replaces the former LSC Communications and R.R. Donnelley printing plants, about 1.5 million square feet across 144 acres. Initial capacity is 100 MW with potential expansion to 300 MW. CoreWeave is the tenant, with the site co-developed by Chirisa Technology Parks and Machine Investment Group, and $4 billion in capital came from Blue Owl Capital and affiliates of the co-developers. The company projects about 600 construction jobs and roughly 70 full-time roles at launch scaling to about 175. A Turner and Wohlsen joint venture won the construction contract. Lancaster city negotiated a community benefits agreement with the developers, and the city's proposed data center rules would not apply retroactively to these two sites.

Know your rights

In Pennsylvania, a data center on industrial land usually needs a special exception or conditional use, decided by a local Zoning Hearing Board after a public, quasi-judicial hearing. Neighbors can request party status, cross-examine witnesses, and build an evidentiary record. Municipalities can also write data-center ordinances with enforceable standards.

Take action

Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and ask your municipality for a moratorium and a real ordinance.
