PJM Interconnection faces pressure to overhaul its grid management
PJM Interconnection is proposing operational changes to address severe grid strain from AI and data center demand, as major utilities consider withdrawing from the organization.
PJM Interconnection, a Regional Transmission Organization managing the power grid in the United States, is facing significant operational strain from the surge in data center and artificial intelligence energy demand. This week, the grid operator released a 70-page white paper stating that the region has a limited timeframe to implement fundamental operational changes. In a forward to the report, PJM CEO David Mills stated that the current situation is not tenable, highlighting the urgency of the crisis. The pressure is mounting as American Electric Power, a utility company operating within the PJM territory, is considering withdrawing from PJM.
The grid’s current bottleneck stems from a backlog of interconnection requests—which are applications to connect new power sources to the electrical grid. In 2022, PJM paused applications for new generating sources to manage the queue. However, “PJM’s sclerotic approval process” meant that out of more than 300 gigawatts of projects in the queue in 2022, only 103 gigawatts signed agreements, and just 23 gigawatts have been connected so far. Since PJM recently reopened the queue, developers have filed more than 800 interconnection requests representing 220 gigawatts of new power, leaving the operator struggling to process the volume.
This backlog has drawn criticism from utility executives. During an earnings call on Tuesday, Bill Fehrman, AEP’s CEO, expressed skepticism about the grid operator’s performance. “The current state of PJM’s performance and stakeholder approval process does not give me great confidence that these issues will be resolved anytime soon,” Fehrman said. He added that without immediate action, he expects the same grid conversations could persist in 10 years, noting that the market worked well when supply exceeded demand but has now entered a very different period.
To address these challenges, PJM has proposed three options for grid management in its white paper:
- Longer-term commitments: Requiring utilities and power generators to make larger, longer-term supply commitments, extending beyond the current three years requirement. This faces hurdles as turbine prices rise due to demand from hyperscalers—large-scale cloud computing providers—with new power plants facing earliest installation in the early 2030s.
- Reliability tiering: Changing reliability guarantees so that customers who pay less could have their power cut first. This option faces potential political pushback driven by rising consumer utility bills and “anti-data center animus” in key regions like Northern Virginia.
- Real-time market transition: Moving closer to a real-time market where supply and demand dictate prices, without entirely eliminating the stability of long-term contracts.
Why it matters
PJM Interconnection, the largest US power grid, is facing significant strain from the surge in data center and AI energy demand, forcing the organization to propose fundamental operational changes to avoid potential utility departures and grid instability.
