PJM’s 60-GW Warning Puts EV Charging on the Same Collision Course as Data Centers
By Keith Reynolds | Publisher & Editor, ChargedUp!
PJM Interconnection is sounding a blunt alarm: the grid operator sees a potential power supply shortfall of as much as 60 gigawatts over the next decade, driven largely by the pace of data-center expansion and other electrification loads like EV chargers. If that number holds, it’s not just a utility-planning problem; it’s also a siting, interconnection, and economics problem for every fast-charging project in PJM territory.
The timing is what makes the warning actionable. PJM’s own updated long-term forecast shows peak demand accelerating fast enough to rewrite planning assumptions: PJM expects the summer peak to climb ~85,000 MW over the next 15 years (to 241,000+ MW), and projects ~3.6% annualized summer peak growth over the next decade—an order-of-magnitude jump compared with the early-2020s outlook. Data centers are explicitly called out as a major driver in multiple zones, alongside other large-load additions.
That demand trajectory is colliding with resource adequacy and interconnection reality. In North American Electric Reliability Corporation's latest Long-Term Reliability Assessment, the PJM section describes an “extreme and rapid tightening of supply and demand” and shows PJM’s anticipated reserve margin falling below its Installed Reserve Requirement in 2029. The assessment also notes accelerated generator retirements outpacing additions, and highlights that a large share of new interconnection requests are variable renewables—valuable, but not always aligned with winter reliability needs without firming resources.
Meanwhile, analysts tracking data-center pipelines see the same near-term mismatch. BloombergNEF’s data cited by Utility Dive suggests PJM alone could add ~31 GW of data center load over the next five years, roughly in the range of expected new generation additions over a similar window. This would be an uncomfortable setup even before factoring in delays, attrition, and transmission constraints.
Why this matters for charging developers and property owners
For EV charging, the implication isn’t not to build. It’s that power has become the gating item—and increasingly, a competitive moat. In PJM markets, where capacity prices have already shown how quickly supply-demand balance can tighten, the next wave of winning charging sites will look less like best retail corner and more like best electrical address. Three areas in particularly will experience developments:
Interconnection timelines and upgrade costs. Large loads (data centers, industrial electrification, fleet depots) tend to land in clusters. Once a substation’s headroom is spoken for, everyone else inherits longer studies, bigger upgrades, and more uncertainty. NERC flags PJM’s growing transmission planning complexity tied to localized large-load growth, exactly the pattern that can turn a 12-month charging build into a multi-year exercise.
Demand charges and peak panic. Even where utility service is available, fast-charging can create sharp peaks that blow up the bill. As system peaks rise and local feeders get stressed, tariffs rarely get friendlier. This pushes projects toward power-sharing cabinets, tighter site controls, and serious load-management strategies.
A bigger role for behind-the-meter power. If grid timelines can’t match commercial timelines, the menu expands: batteries sized for peak shaving and interconnection-friendly ramping, on-site generation where permitted, and microgrid-ready switchgear that lets sites scale in phases.
The playbook shift: build chargers like flexible grid assets
The pragmatic opportunity here is that EV charging is not a fixed industrial load; rather, it’s a schedulable one. If PJM and its utilities are heading into a decade where flexibility is as valuable as steel-in-the-ground generation, charging sites that can modulate load, cap peaks, and participate in managed programs will be easier to site and easier to finance.
PJM’s 60-GW warning is ultimately a signal that electrification is no longer a category; it is a competition for megawatts. The lesson for charging is broad: lock in power early, design for controllability, and treat energy strategy as part of the real estate strategy. The next decade will reward projects that arrive with a grid plan, not just a site plan.
