The largest electrical grid in the U.S., the PJM Interconnection, just got a brutal report card from its watchdog, Monitoring Analytics. The verdict: wholesale electricity prices have nearly doubled, hitting $136.53 per megawatt-hour, up from $77.78 last year. And the culprit is about as surprising as finding out that a tech company is using a lot of energy.
Yes, data centers are the ones draining the grid, and PJM's response has been about as effective as trying to fix a leaky pipe with duct tape. The market monitor didn't mince words: "The price impacts on customers have been very large and are not reversible." It added that things will get even worse unless PJM gets its act together on data center demand.
PJM is a ripe target for criticism because, in 2022, just as data center construction was ramping up, the grid operator paused applications for new generating sources, citing a years-long backlog. It only recently started accepting new requests. Meanwhile, electricity demand from data centers has risen dramatically - particularly in Northern Virginia, a part of the country that is thick with data centers.
This price spike is a reminder of a deeper problem: The U.S. power grid was not designed for the electricity demands of an AI-driven economy, and the gap between what the grid can deliver and what the industry needs is widening. Monitoring Analytics was direct: without rising demand from data centers, "the capacity market would not have seen the same tight supply demand conditions, the same high prices observed."
The watchdog also blamed PJM's lack of transparency and for delaying much-needed software upgrades, which "have been delayed by multiple years and have no firm expected implementation date." The report comes on the heels of a white paper from PJM that suggested three paths forward, but none appealed to AEP, one of the region's largest utilities, which has threatened to leave the grid altogether.
Monitoring Analytics was similarly unimpressed, saying PJM was using the crisis "as a pretext" for tearing up the way its power market works. The solution, it said, "starts with the recognition that the source of the current issues is data center load." In other words, it's the data centers, stupid.
