Data Center Power Shortfalls in PJM Territory: Why Developers Are Turning to Bridge Generation

PJM's footprint spans 13 mid-Atlantic and Midwest states plus the District of Columbia, and within that footprint sit some of the most concentrated data center markets in the world — Northern Virginia's Data Center Alley in Loudoun County foremost among them, alongside significant and growing clusters in Ohio and Pennsylvania. That concentration is precisely why interconnection timelines in these specific corridors carry extra weight for developers.

Interconnection studies are fundamentally about transmission system capacity at a given location, not just administrative processing speed. In a region where large-load and generation interconnection requests are already dense, the transmission and substation upgrades required to serve one more large facility are more likely to be substantial, and more likely to compete with upgrades already queued for neighboring projects. Being in a high-demand zone can mean a longer effective wait for permanent capacity even as PJM's broader queue reform improves throughput system-wide.

That dynamic is a large part of why bridge generation has moved from a contingency plan to a default line item for developers building in these corridors specifically. A data center campus in Loudoun County, or an industrial-scale facility in Ohio or Pennsylvania, faces the same fundamental gap described elsewhere in this series — the difference between a required energization date and the date permanent interconnection capacity actually becomes available — but often with less room to simply choose a less-constrained location, since the whole reason to build there is proximity to existing fiber, power and market infrastructure.

Aero-derivative gas turbines fit this specific problem well because they can be sited on or adjacent to a campus, staged in modular blocks that scale with the facility's actual build-out, and mobilized on a timeline set by the project rather than by the local transmission queue. That decoupling is the point: a developer building in a high-demand PJM corridor doesn't have to make the facility's opening date hostage to a queue position it doesn't fully control.

NYTS works with data center developers and their EPC and utility partners across PJM territory to size and structure this kind of bridge — see industries NYTS serves for how this applies across sectors, or submit a Request a Proposal with your project's location, capacity and timeline to start a technical assessment.
