PJM Interconnection Warns Grid Overhaul Must Be Completed Within Years, Not Decades

PJM Interconnection, the operator for a major U.S. power grid covering the densest data centre developments including Northern Virginia, has released a white paper stating the region has only years, not decades, to overhaul its operations. The organisation admits the current situation is not tenable due to surging demand from artificial intelligence data centres, marking a significant shift from its historical role of quietly matching supply with demand while maintaining low electricity prices for customers.

PJM CEO David Mills has publicly stated that the current operational model requires immediate fundamental change. The report highlights a significant backlog of interconnection requests, noting that since the queue was recently reopened, power companies and project developers have filed more than 800 requests for 220 gigawatts of new power. This surge coincides with a period where the market has been locked into a three-year commitment mindset, which is ill-suited for the rapid deployment of solar and batteries and the current shortage of natural gas turbines.

Despite a recent reopening of the interconnection queue, the scale of the challenge remains immense. In 2022, PJM paused applications for new generating sources due to a years-long backlog, preventing new projects from connecting just as demand began to grow. Of the more than 300 gigawatts of projects in the queue at that time, only 23 gigawatts have been connected so far, with many developers withdrawing rather than wait out the process.

The organisation faces criticism from stakeholders, including American Electric Power, which is considering withdrawing from PJM entirely. Bill Fehrman, CEO of American Electric Power, cited a lack of confidence in resolving current issues, stating that the current state of PJM's performance does not give him confidence that these issues will be resolved anytime soon. He noted that the market worked well when supply exceeded demand but is now in a very different time driven by cloud computing and AI.

To address the strain, PJM has proposed controversial options such as requiring longer utility commitments, implementing tiered reliability guarantees where lower-paying customers face higher outage risks, or a shift to a real-time pricing model. However, these measures face significant industry and political resistance. The tiered reliability option, in particular, risks splitting the territory into groups of haves and have nots, a move unlikely to be supported by politicians seized on rising power prices and anti-data centre sentiment.

The proposed solutions are further complicated by the reality that the market is locked into a timeline that conflicts with modern energy deployment speeds. Solar and batteries can be installed at least two to three times faster than the current three-year commitment model allows, while natural gas turbines are not expected to be available until the early 2030s. With rising utility bills and a hostile environment for proposed solutions, the grid operator may not have years to sort things out, looking instead like a messy few years ahead.
