Dauphin County Data Center Could Replace Warehouse Development

Executive Summary

Dauphin County, Pennsylvania, is seeing a notable land use pivot: a site previously approved for warehouse construction on Penhar Drive is now being repositioned for a data center complex. The shift reflects accelerating regional demand for digital infrastructure and signals that industrial land near power corridors is being reassessed at the ownership level. Warehouse developers and adjacent businesses operating under traditional industrial assumptions face repricing risk. For data center investors and powered-land holders, this is a meaningful entry signal in a mid-Atlantic market that has historically flown under the radar compared to Northern Virginia or Phoenix.

What Happened

Township commissioners in Dauphin County, Pennsylvania, approved a land development plan in August 2025 for the construction of four warehouses on Penhar Drive — three of which were slated for a single development phase. That approval set conventional industrial development in motion on what was presumably shovel-ready land.

The warehouse plan is now facing displacement. A data center complex is being proposed as a replacement use for the same site. The scope and square footage of the proposed data center have not been fully detailed in the available source, but the project is substantial enough to override an already-approved warehouse development plan — a meaningful procedural threshold.

Commissioners are evaluating the data center proposal, which would require revisiting the prior approval and likely initiating a new review cycle. The site on Penhar Drive is the locus of the proposed conversion.

Why This Matters

This is not simply a one-site land swap. When a township-approved warehouse plan gets displaced by a data center proposal, it signals that operators and developers are willing to restart permitting cycles from near-zero because the economics of data center use are that much more compelling on a given parcel. That calculus is being repeated across secondary markets.

Dauphin County sits in central Pennsylvania, a geography that is increasingly attractive for data infrastructure: moderate land costs, proximity to fiber corridors serving the Northeast, and access to PPL Electric's transmission infrastructure. Industry context: secondary Pennsylvania markets have seen rising interest from hyperscale and colocation operators seeking alternatives to the saturated Northern Virginia corridor.

The fact that this conversion is happening at the township commissioner level — not as a developer's greenfield announcement — means the momentum is coming from actual deal flow, not speculative announcements. That's a different quality of signal.

For adjacent landowners and developers holding industrial-zoned parcels in the county, the question is now whether their sites could command a data center premium. That conversation requires an honest evaluation of power access, fiber proximity, and setback requirements.

Power & Interconnection Impact

Data centers are power-intensive assets. Even a modest campus-scale facility in the 20–100 MW range represents a material new load for the serving utility. Assumption: the Penhar Drive site would be served by PPL Electric Utilities, which operates transmission and distribution infrastructure throughout Dauphin County and is interconnected within PJM, the regional transmission organization covering much of the mid-Atlantic and Midwest.

PJM's interconnection queue has faced well-documented backlogs, and new large loads — data centers included — must navigate the same capacity study and interconnection process as generation assets. Developers will need to determine whether existing substation capacity in the Penhar Drive service area can absorb the new demand or whether a substation upgrade or new dedicated feed is required. That determination affects both project timeline and capital cost materially.

Industry context: utility-side load interconnection timelines in PJM have stretched to 18–36 months in constrained areas. Investors underwriting data center deals in secondary Pennsylvania markets should pressure-test power delivery assumptions early.

Land, Zoning & Permitting Impact

The most immediate complexity here is procedural: the site already has an approved development plan for warehouses. Substituting a data center triggers a new use classification, and in most Pennsylvania townships, data centers are not a by-right use in standard industrial zones. They may require conditional use approval, special exception, or a zoning ordinance amendment — each carrying its own public hearing requirements and appeal windows.

Dauphin County municipalities have varying levels of experience reviewing data center applications. Assumption: the township involved has limited precedent for data center conditional use hearings, which typically means a longer educational cycle with the planning commission before approval. That's a timeline risk developers must model explicitly.

Environmental review considerations also shift. Warehouse footprints generate traffic and stormwater concerns; data centers generate noise (cooling systems), significant impervious surface, and substantial utility easement requirements. A new stormwater management plan and possibly a revised traffic study would likely be required.

The net effect: developers should expect a permitting reset, not a simple amendment to the existing approval. Early engagement with township planners and commissioners is essential.

Investment Takeaway

Land value uplift is real but uneven. Industrial parcels with power access in Dauphin County should be reassessed for data center potential. Sites without adequate substation proximity will not benefit from the same repricing.
Permitting timelines are the hidden cost. Restarting approval from an existing warehouse plan adds 6–18 months in most township jurisdictions. Factor that into IRR models.
PJM load interconnection is a gating item. Before underwriting a data center deal in this market, confirm substation headroom with PPL directly. Assumption: capacity constraints exist in portions of the county given regional load growth.
Warehouse developers on adjacent sites face softening demand. If the most attractive parcels on Penhar Drive are being redirected to data center use, remaining warehouse supply competes for a smaller slice of industrial tenants.
Secondary PA markets are entering a new pricing regime. Data center demand is pulling asset values in markets that have not historically competed for this capital. Early movers on powered land capture the spread.

InfraSale Market Angle

For investors actively tracking powered land and data center site acquisition, Dauphin County's Penhar Drive situation is a live case study in secondary market conversion. The audience most immediately affected: investors holding or evaluating industrial land in central Pennsylvania, and data center developers with flexible site criteria who have not yet looked east of Pittsburgh or south of Allentown.

The practical move is to identify other industrial-zoned parcels in Dauphin and adjacent counties — Cumberland, Lebanon, York — that share the site characteristics making Penhar Drive attractive: flat topography, highway access, and proximity to transmission infrastructure. Those sites are still priced as industrial land. That window is closing.

Developers who move through zoning and interconnection diligence now — before a public data center announcement resets comparables — will have a structural cost advantage over those who respond to the press release.

FAQ

What are the typical zoning challenges for data center development?

Data centers often fall outside standard by-right uses in industrial zones, requiring conditional use approval or special exception hearings. These processes add public notice requirements, planning commission review, and appeal windows that can extend timelines by 6–18 months. Noise from cooling infrastructure and large utility easements are common sticking points in municipal review.

How will a data center affect local infrastructure in Dauphin County?

A data center of meaningful scale — even 20 MW — represents a significant new electrical load for the serving utility and distribution network. Developers will need to assess substation headroom through PPL Electric and, if PJM interconnection studies are required, prepare for a multi-step review process. Water supply for cooling and fiber connectivity are secondary but material infrastructure requirements.

What investment opportunities arise from this land use change?

The primary opportunity is land basis arbitrage: industrial-zoned parcels in Dauphin and adjacent counties are still priced as warehouse land, while data center demand is beginning to pull values higher. Investors who can identify sites with power access and clear zoning paths capture that spread. The risk is permitting timeline and utility capacity — both of which require hands-on diligence rather than desktop underwriting.

Does this development signal broader demand for data centers in Pennsylvania?

Industry context: Pennsylvania sits in a favorable position for data center growth — lower land costs than the mid-Atlantic core, access to PJM's transmission network, and improving fiber density along the I-78/I-81 corridor. Dauphin County is not an isolated case; it is part of a pattern of secondary market activations driven by hyperscale and colocation demand that has saturated primary markets.

What should landowners near the Penhar Drive site do now?

Landowners holding industrial or commercially-zoned land in the immediate area should commission a preliminary power availability study and review their current zoning classification. If a data center operator is evaluating the corridor, comparable parcels will attract attention. Proactive positioning — including utility pre-application meetings and title review — shortens time to term sheet.
