Your electric bill is now an AI bill

What the market monitor found

Start with the market most of the East Coast lives inside. PJM Interconnection runs the wholesale power market for thirteen states and the District of Columbia, Virginia and Maryland and Pennsylvania and Ohio and New Jersey among them. PJM has an independent referee called Monitoring Analytics, and in late August the referee told PJM’s members something worth reading twice. Through the first seven months of 2026, existing and forecast data-center demand accounted for about 9 percent of wholesale power costs, roughly $10.48 per megawatt-hour by that accounting. The monitor is careful to call that a floor, because it leaves out the way the same demand pushes energy and transmission prices up on top of it. Wholesale costs over those seven months came to $56.7 billion, up 46 percent from a year earlier.

The sharper number is in the capacity market. Capacity is the insurance the grid buys years ahead so the lights hold on a hot Tuesday in July. PJM auctions it, and when the auction clears high, everybody’s bill carries the cost as a pass-through. The 2026/2027 auction cleared at $329.17 per megawatt-day, which is the ceiling the auction is allowed to reach, roughly eleven times the level of two years earlier. Monitoring Analytics attributed $29.4 billion of the capacity charges across the last four auctions, about 46 percent of the total, to existing and forecast data-center load. In the most recent auction alone the data-center share was 38 percent. Capacity, the fastest-moving piece of the bill, more than tripled year over year.

Where it lands on your statement

Read the table and the pattern is not subtle. The three PJM states climbed. Virginia, the data-center capital of the planet, went from 15.23 cents a kilowatt-hour to 17.22 in twelve months. Maryland and Ohio moved the same direction. Florida, which is not in PJM, sat a hair below its own prior June. That does not let Florida off the hook, because Florida has its own large-load fights coming and its own utilities that will have to build for new, flat, enormous customers. The table says something narrower and more useful than “data centers raise your bill.” A bill moves when the grid it sits on has to buy or build for a 24-hour factory that did not exist last year, and PJM is where that is happening first and hardest.

The wall the regulators are building

Regulators heard the same alarm and started building walls. In Virginia the State Corporation Commission approved a new rate class, GS-5, for customers drawing 25 megawatts or more. It takes effect on January 1, 2027, and it is written to keep a campus from vanishing and leaving households holding a substation. The terms are the interesting part: a fourteen-year commitment, a floor that bills the customer for at least 85 percent of its contracted demand whether it uses the power or not, and collateral the commission has pegged in the neighborhood of $1.5 million per megawatt. Georgia Power, ComEd and Oncor have written their own versions. A 2026 comparison by the energy consultancy E3 found that the very same 25-megawatt load can pay anywhere from about 6.4 cents a kilowatt-hour under one utility’s tariff to about 9.4 cents under another, a spread of nearly half, depending only on which wall it landed behind.

Industry-funded analysts push back, and the honest version of their case belongs here. They argue that outside PJM’s particular capacity math, most recent retail increases were not “caused” by data centers, and that the new large-load tariffs are the proof the system is working, walling households off from the risk before it arrives. There is something to that. A tariff like GS-5 exists precisely so the tenant, not the neighbor, carries the wire. Inside every commission, the fight now is over who signs for the wire, and whether the signature holds up when a tenant cancels or a recession hits.

What it costs you nationally

At the national level, Goldman Sachs Research put out a forecast in February that consumer electricity inflation would run about 6 percent from 2026 into 2027 before easing, driven in part by AI power demand layered on an aging grid. Treat that as a forecast, not a meter reading, and notice the hedge inside it: the number is broader than data centers alone. The sentence that survives all the caveats is the one for a reader in Virginia or Florida. If you live on a grid that is adding gigawatts of round-the-clock load, and your regulator has not yet isolated that load behind a wall like GS-5, you are inside the experiment whether you signed up for it or not.

The bottom line for your bill

“The cloud” is not weather. It is a queue position, a capacity charge, and a fourteen-year contract with your utility’s name on one side. The next part of this series follows the same building to the thing it drinks.
