PJM Projects 49 GW Shortfall by 2028 as AI Data Centers Surge

PJM Interconnection, the largest U.S. grid operator serving more than 65 million people across 13 states, faces a projected generation shortfall of up to 49 GW by 2028 as artificial intelligence data center load growth accelerates faster than new capacity additions are brought online. Analysis presented to PJM governors in late 2025 framed the gap as equivalent to approximately 49 large natural gas power plants, while capacity auction clearing prices rose 833 percent between the 2024-2025 and 2025-2026 delivery years before adding another 22 percent increase for 2026-2027.

Data Center Load Profile and Grid Impact

U.S. data centers consumed an estimated 177 to 192 terawatt-hours of electricity in 2024, representing approximately 4 to 5 percent of total national demand, according to EPRI research published in February 2026. EPRI projects that share will rise to 9 to 17 percent by 2030, with annual consumption potentially reaching 793 TWh in the high scenario. The Lawrence Berkeley National Laboratory projects data center demand growing from 176 TWh in 2023 to between 325 and 580 TWh by 2028.

AI-specific workloads introduce grid reliability challenges beyond aggregate volume. Large GPU clusters produce power fluctuations of hundreds of megawatts within seconds as training jobs begin or end, creating significant challenges for system balancing. A July 2024 voltage fluctuation in northern Virginia triggered the simultaneous disconnection of 60 data centers and produced a 1,500 MW power surplus, requiring emergency grid adjustments to prevent cascading outages. PJM is developing connect-and-manage rules under which data center load growth that does not bring associated new supply faces curtailment before standard demand response is deployed.

Direct Power Agreements and Private Generation

Hyperscalers are bypassing spot market procurement and contracting directly for dedicated generation. Amazon Web Services arranged to source approximately 960 MW directly from a nuclear power plant in Pennsylvania. Meta secured power from a new 200 MW gas-fired plant in New Albany, Ohio, expected to begin commercial operation in 2026. CloudBurst signed a long-term agreement with Energy Transfer for up to 450,000 MMBtu per day of natural gas via the Oasis Pipeline, sufficient to generate nearly 1.2 GW.

On March 4, 2026, Google, Meta, Amazon, Microsoft, OpenAI, Oracle, and xAI signed a White House pledge committing to fund data center power and grid upgrades. The agreement was brokered through coordination with the Electric Power Supply Association and infrastructure firms including Clayco, with connections to PJM Large Load Interconnection processes.

Large-Load Tariffs and Regulatory Response

As of November 2025, the DELTa Database tracked 66 large-load tariffs and service rules across 34 states and 51 utilities, with 36 already approved and 29 pending or proposed. These tariffs require data centers to directly fund generation and grid infrastructure built to serve them, addressing the infrastructure gap without socializing costs across residential and small commercial ratepayers.

In January 2026, the National Energy Dominance Council joined Trump Administration energy officials in issuing a Statement of Principles urging PJM to run a one-off reliability backstop auction offering 15-year capacity contracts for new plants, create large-load rate classes so data centers shoulder more infrastructure costs, tighten load forecasts, and cap interconnection studies. Goldman Sachs projects that data center power consumption will boost core inflation by 0.1 percent in both 2026 and 2027 as rate increases spread from PJM to adjacent regions.

On-Site Generation as Grid Stress Mitigation

Bloom Energy reported that its solid oxide fuel cells deploy at 50 MW scale in as little as 90 days and 100 MW in 120 days when gas supply and permits are in place, offering data center operators a path to on-site power that bypasses grid interconnection queues entirely. Bloom had deployed approximately 1.4 GW of Energy Server systems at over 1,000 locations across nine countries as of 2025 and announced a capacity expansion to 2 GW annual production by end of 2026. In 2024, Bloom Energy announced a procurement agreement with American Electric Power for up to 1 GW of fuel cells, with AEP placing an initial order for 100 MW.

Critical Perspective

The 49 GW projection is built on current trajectory, not committed demand — a meaningful distinction when 40% of announced hyperscale projects have not yet executed power purchase agreements. Comparable market forecasts published in 2021–2022 for battery storage and EV charging overestimated actual 2024 deployment by 25–40% once interconnection queue delays and supply chain constraints were not modelled. The question energy professionals should be asking: what fraction of this forecast is backed by executed offtake agreements versus letters of intent?
