By 2030, the PJM Interconnection is projected to experience a dramatic increase in reliability risks, mainly due to the explosive growth of large-load data centers across the region. A recent independent study, commissioned by the Pennsylvania Public Utility Commission, forecasts that PJM’s loss of load expectation (LOLE), a key reliability benchmark, could be as much as 100 times higher than the grid’s planning criterion if current data center load trends continue unchecked.
Key figures
0.59 LOLE under 2026 forecast, nearly six times PJM target
13.20 LOLE under worst-case, over 100 times PJM standard
One loss of load event every 10 years is PJM’s target criterion
Report projects surpassing PJM reliability limits
The study was prepared by Synapse Energy Economics, Mondre Energy, and Aspen Technologies and commissioned by the Pennsylvania PUC to analyze electricity resource adequacy under multiple scenarios. PJM’s current planning standard targets a LOLE of 0.1, meaning no more than one expected loss of load event per decade. The report, however, found that under a “reference scenario” based on PJM’s 2026 load forecast, the region would reach a LOLE of 0.59 by 2030, nearly six times the target standard.
Worse still, the study’s “high-load, low-supply” scenario, reflecting continued strong data center expansion and resource constraints, projects a staggering LOLE of 13.20. This translates into an expectation of more than 13 days with loss of load events per year, a marked departure from PJM’s reliability goals. Only a scenario with zero new data centers added between now and 2030 was able to maintain LOLE within PJM’s target range.
Data center surge as primary driver
The reliability risk is linked almost entirely to soaring power demand from new hyperscale data centers in PJM states, particularly Pennsylvania and Virginia, regions that have seen a development boom in digital infrastructure. These data centers, supporting cloud, AI, and enterprise compute, each add significant recurring load to already strained grid capacity.
The study’s findings indicate that growth in this sector has already begun to overwhelm PJM’s resource adequacy margins. Both operational and planned facilities are driving up peak load projections well beyond levels anticipated even a few years ago, and the region’s current resource pipeline, especially new build generation or demand response, lags behind rising demand profiles. The resulting imbalance threatens traditional planning norms and could catalyze multi-day reliability challenges as early as 2027.
Scenarios and planning standards explained
PJM utilizes the LOLE metric to assess the risk of electricity shortages relative to available generation and grid conditions. The commonly accepted target is 0.1, signifying that the system-wide risk of one loss-of-load event every 10 years meets reliability obligations for resource planning.
However, the reference case in the new study gives a 2030 LOLE of 0.59, while the most aggressive scenario forecasts 13.20. The high-load, low-supply scenario assumes faster-than-planned growth in data center connections and less successful delivery of new generation and grid upgrades. The result would be a reliability outcome “over 100 times” more severe than PJM intends for prudent operation, according to the report. Notably, the only scenario to remain compliant with the 0.1 standard is one with no further data center-driven demand increases.
Implications for asset owners and developers
The growing gap between regional electric supply and demand has immediate implications for data center site developers, power providers, and investors. Higher LOLE expectations increase the likelihood of forced curtailment, more frequent grid emergencies, and potentially higher wholesale power volatility within PJM. For owners and operators, project bankability and operational resilience may depend on local grid conditions deviating from the system-wide risk baseline.
Pennsylvania PUC Chairman Steve DeFrank emphasized the urgency of the findings, calling for significant new action on energy strategy and resource deployment within PJM. Regional grid planners, developers, and digital real estate investors will need to closely monitor ISO queue progress, transmission upgrades, and local load forecasts in order to accurately assess risk-adjusted project value.
Regulatory and market response ahead
The report’s warnings highlight a growing regulatory concern that the rapid pace of data center construction could outstrip the region’s ability to maintain grid reliability. As PJM’s interconnection queue lengthens, the need for new capacity, storage, and transmission approval is likely to grow urgent. Inaction or delays risk a structural reliability deficit manifesting as recurring load events, impacting end users from hyperscalers to municipalities reliant on stable service.
For investors and developers, these findings reinforce the strategic significance of close, real-time alignment with both regional planning authorities and state-level policy changes. Energy buyers and digital asset investors may need to factor higher reliability risk premiums, and thus altered site selection and procurement priorities, into current market evaluations across Pennsylvania, Virginia, and other PJM states.
What this means for buyers
This report directly affects land, power, and data center capacity assets in PJM states. The expectation of up to 13 days per year of load events, if data center buildout continues at current pace, changes the risk analysis for project underwriting. Asset buyers should re-assess site selection and procurement based on projected load growth and prioritization of locations with stronger resource adequacy through 2030.
