PJM Power Costs Soar as Watchdog Flags Market Failures, Data Center Strain

EAGLEVILLE, PA – March 12, 2026 – Wholesale electricity costs skyrocketed across a 13-state region in 2025, driven by non-competitive market conditions and unprecedented demand from data centers, according to a scathing new report from the grid’s independent watchdog. The annual State of the Market report, released today by Monitoring Analytics, LLC, paints a troubling picture for the 67 million people served by PJM Interconnection, the nation's largest grid operator.

While the report found PJM’s day-to-day energy market to be competitive, its crucial capacity market—which ensures long-term grid reliability—was deemed fundamentally flawed. The findings point to a system under immense strain, leading to a nearly 50 percent increase in the total cost of wholesale power and raising urgent questions about who will bear the financial burden of powering the digital age.

"Our analysis concludes that the results of the PJM Energy Market were competitive in 2025," said Joseph Bowring, the Independent Market Monitor. However, he delivered a starkly different assessment of the long-term market, stating, "Our analysis concludes that the results of the capacity market auctions for the 2025/2026, 2026/2027, and 2027/2028 Delivery Years were not competitive, in significant part as a result of forecast demand for data centers."

The Rising Toll on Consumers

The financial impact detailed in the report is staggering. The total cost of wholesale power surged by 48.9 percent, jumping from $55.52 per megawatt-hour (MWh) in 2024 to $82.67 per MWh in 2025. While fuel and transmission costs contributed to the rise, the most dramatic increase came from the capacity market. The cost of capacity, which makes up about 16 percent of the total wholesale bill, exploded by an astounding 262.3 percent.

These wholesale increases are not abstract figures; they translate directly into higher electricity bills for households and businesses. The report's findings align with ratepayer spikes that began on June 1, 2025, as the results of a high-priced capacity auction began to hit customer accounts. Approximately a quarter of a typical consumer's bill is tied to these capacity charges.

Further compounding the financial pressure on consumers is a long-standing issue with market design flaws. When the grid is congested, it creates price differences across locations, generating revenue known as congestion charges. According to the monitor, this revenue belongs to customers and should be returned to them. However, the report reveals that due to flaws in PJM’s Financial Transmission Rights (FTR) market, only 59.4 percent of congestion fees were returned to customers in the first seven months of the current planning period.

This gap is not new. The monitor calculates that customers have been short-changed by a cumulative $5.8 billion since the 2011/2012 planning period, a direct result of these market design flaws. In 2025 alone, total congestion revenue ballooned by 80.9 percent to over $3.17 billion, widening the pool of money not being fully returned to the customers who paid it.

Data Centers and the Capacity Crunch

The report squarely identifies the booming data center industry as a primary driver of the crisis in the capacity market. PJM, whose territory includes the world's largest concentration of data centers in Northern Virginia, is at the epicenter of this demand shock. The IMM's analysis found that soaring capacity auction prices, which jumped from roughly $2 billion to nearly $15 billion in a recent auction, were almost entirely due to existing and projected data center loads.

This new, power-hungry demand is straining a system that is already struggling to keep pace. PJM has forecasted a potential shortfall of 60 gigawatts of power within the next decade as data center demand combines with the broader electrification of transportation and heating. The problem is exacerbated by a severe bottleneck in connecting new power sources to the grid. The time required to bring a new generation project online has swelled from under two years in 2008 to more than eight years today, leaving PJM with a massive backlog of proposed projects waiting for approval.

The increasing demand was reflected in PJM's operations in 2025, which saw the grid set new records for both winter and summer peak loads, with average hourly load increasing by 3.7 percent over the previous year.

A Market Under Scrutiny and the Push for Reform

Faced with these mounting pressures, PJM and its federal regulators are scrambling to respond. PJM has initiated several stakeholder processes and rule changes aimed at managing the influx of large loads like data centers and accelerating the interconnection of new power plants. In February 2026, the grid operator submitted filings to the Federal Energy Regulatory Commission (FERC) to revise its tariffs, seeking to clarify rules for data centers with on-site generation and establish an Expedited Interconnection Track for new power sources.

These moves follow a directive from FERC in late 2025 and increasing pressure from bipartisan lawmakers who have urged PJM to implement more regulations to protect consumers from runaway costs. However, some of PJM's proposals have been met with skepticism from industry and consumer groups, who worry they may not fully address the core issues of grid reliability and cost containment.

The 2025 market report underscores the complex and often contradictory forces at play. While solar generation grew by an impressive 41.2 percent, generation from coal also increased by 19.0 percent to meet demand, illustrating the immense challenge of transitioning the grid to cleaner resources while maintaining reliability. As PJM navigates the trilemma of reliability, affordability, and the clean energy transition, the watchdog's report serves as a critical warning that, for now, its markets are not delivering competitive outcomes for millions of customers.
