J.G. Petrucci files 100MW Allentown data center plan

J.G. Petrucci Company has submitted plans for a 100MW data center and an on-site substation at 1024 N. Bradford Street in Allentown, Pennsylvania, according to Frank Kane, the city's managing director. WFMX and Lehigh Valley Public Media first reported the filing, and Data Center Dynamics carried it. The building would span 146,000 sq ft. The Morning Call reports the company is in discussions with a potential end user, with construction potentially starting in early 2027 and the facility launching the same year.

The property's prior life was a warehouse plan. J.G. Petrucci secured planning approval in 2022 for a 146,000 sq ft industrial development called the Allentown Flex Center. The new filing pivots that approval toward data center use. That distinguishes it from the other big Allentown project: Quantum Group is converting an empty warehouse at 2401 W. Emaus Avenue into a roughly 250,000 sq ft data center. One project recycles a shell; the other re-purposes an approval.

J.G. Petrucci, founded in 1987, is a privately held developer with a portfolio of more than 7 million sq ft of commercial, industrial, and residential property across the Northeast. It already offers industrial space at Bethlehem's Lehigh Valley Industrial Park. The company did not comment to local press, according to DCD.

The filing has the look of a speculative build. No tenant is named; the only public reference is to a potential end user in discussions. A 100MW block of uncommitted power is a large position, and the proposed on-site substation is the most concrete commitment in the plan. At 100MW, substation work is a serious line item, and the proposal puts it on the schedule before a tenant is in hand. That suggests a developer willing to spend on grid access in the hope of securing a user before the steel goes up.

The bet is being made as the state's rules shift. DC Byte's September 2025 analysis counted 7.8GW of planned data center load in Pennsylvania, up from 231MW of total IT load in 2021 — exponential growth, in the analyst firm's phrase. Governor Josh Shapiro signed an executive order this month imposing strict requirements on data center development, as DCD reported. The order's terms are not detailed in the coverage, so the effect on this project is unconfirmed. The direction, though, is toward more scrutiny.

The timeline reinforces the risk. Work starting in early 2027 and launching in the same year leaves little room for leasing after completion. That schedule assumes a tenant signs early or that the developer will carry empty capacity. The substation, once built, remains a fixed cost in the project's economics. It does not easily serve another use if the data center stalls.

The figures also point to the kind of tenant this design targets. 100MW across 146,000 sq ft implies a power density that suggests high-performance computing or AI training workloads. Those tenants are few, move slowly, and negotiate long. That makes the absence of an announced user more consequential, not less.

Pennsylvania has attracted a host of data center developments in recent months, according to DCD, and Allentown sits in that current. The city offers a mix of power access and industrial land, a combination that has drawn both the Quantum conversion and the Petrucci filing.

For private investors watching the data center land rush, the project is a reminder of where the durable value sits. Land and approvals are replaceable; a substation connected to the grid is an asset with a long, fixed life. Building one on spec is a statement that interconnection, not steel, is the scarce resource.

What matters now is sequence. Whether the substation moves before a lease is signed tells you who is bearing the interconnection risk. How the state's new rules affect permitting tells you whether the window is closing. J.G. Petrucci's filing puts both questions on the table. The substation is the part worth watching.
