PJM grid strain, capacity auctions and data center impact

Overview

In July 2026, PJM Interconnection faced extreme grid strain during a heat wave. In Northern Virginia, wholesale electricity prices surged past $2,000/MWh, and a sudden 3 GW loss in the region caused flickering lights and voltage disturbances. This instability prompted emergency demand-reduction orders and highlighted the impact of data centers on grid reliability. A July 14 capacity auction cleared at the federal price cap of $325/MW-day, reflecting a 6.8 GW supply shortfall and a record peak demand of 168.2 GW on July 2. The auction is expected to increase electricity costs by approximately $6.3 billion for customers across 13 states, a cost driven primarily by AI-driven data-center loads. In response to these pressures, FERC convened a technical conference to discuss PJM governance reforms, including calls for a more independent and transparent board. On July 28, PJM announced it may begin temporarily interrupting electricity supply to data centers and large industrial consumers (50 MW or more) starting in June 2027 to prevent blackouts. Recent developments show a shifting landscape: Exelon reported a 40% drop in its data-center load as it focuses on transmission security, while research suggests a rise in off-grid, natural-gas-fired power to bypass grid bottlenecks. Meanwhile, PJM has accepted 201.5 GW of proposed power projects into an updated interconnection process to address a forecasted demand increase of up to 70 GW by 2038. On August 14, the New Jersey Board of Public Utilities (BPU) released a study calling for significant reforms to the PJM capacity market, noting that the current Reliability Pricing Model may no longer deliver electricity at the lowest cost following a 20 percent increase in New Jersey electricity bills. The BPU recommended that large new users, such as data centers, be required to provide new generation resources to support their own demand.

Claims

What the coverage asserts, and how many sources carry each claim.

[● 2 SOURCES] PJM Interconnection announced it may temporarily interrupt power to data centers and other large consumers during peak demand to avoid blackouts.
[● 2 SOURCES] U.S. data center electricity consumption is projected to quadruple by 2035 compared with current levels.
[○ 1 SOURCE] The curtailments will apply only to data centers with a power demand of 50 MW or more, starting in June 2027.
[○ 1 SOURCE] An earlier auction to increase generation capacity for the PJM grid failed to meet expected results.
[○ 1 SOURCE] More than 200 entities launched lobbying campaigns on data‑center energy issues between April and June 2026, up from fewer than 100 the prior year.
[○ 1 SOURCE] President Donald Trump promoted a non‑binding declaration supported by hundreds of companies to limit electricity price increases.
[○ 1 SOURCE] The Federal Energy Regulatory Commission (FERC) is examining new regulations to ensure large installations are safely integrated into the grid.
[○ 1 SOURCE] PJM is conducting a new auction for additional generation capacity to address grid deficits.
