What Happened

Monitoring Analytics, the independent market monitor for PJM, says the region’s power costs have jumped hard — and that data-center load is the main culprit. The headline is the number. The story is what the number does once it lands on a bill.

In parallel, communities are treating data centers less like invisible “internet infrastructure” and more like heavy industry: noise, water, property values, and the quiet fear that you’re subsidising somebody else’s profits with your local grid.

The Mechanism: Capacity Markets Don’t Like Surprise Factories

PJM’s core planning and procurement logic is built around forecasting and auctions. That’s fine when demand growth is boring. It gets spicy when demand shows up as a cluster of 200–500MW loads that want to connect on human timelines, not 2030 timelines.

The market monitor’s critique, in plain language: if you bake data-center demand into the general capacity forecast, you push up prices for everyone. If you force large loads to contract for (or fund) new supply directly, you at least keep the costs attached to the customers who created them.

Stakes Map: Who Pays, Who Gets Blamed

• Households and small businesses: the politically fragile layer. They don’t care which auction cleared. They care that “AI” is now a line item on their monthly survival plan.
• Hyperscalers and data-center developers: they want fast interconnects and socialised upgrades. Regulators are starting to treat that as a subsidy by another name.
• Utilities and generators: they like higher prices right up until the backlash turns into rule changes, moratoria, or “build your own power plant” mandates.
• Grid operators and regulators: they’re being asked to do industrial policy with spreadsheets. The fight is not “do we need power?” — it’s “who is allowed to offload risk?”
• Local politicians: they are discovering a new campaign promise: “No more servers in my backyard.”
