Who Pays for the Data Center Power Crunch? A FERC Ruling Puts Building Owners on Notice

The fight is over who absorbs the cost of a 6.8-gigawatt power shortfall in the PJM grid, and FERC has signaled that data centers, not existing customers, should pay for the demand they drive. The Federal Energy Regulatory Commission conditionally approved PJM's emergency backstop procurement, an arrangement worth roughly $20 billion to secure scarce capacity, but paused it about five months and demanded changes so the costs fall on the large new loads causing the shortfall. For commercial owners across PJM's 13-state territory, this ruling will help determine how much of the data center boom shows up on their own electric bills.

Key Facts at a Glance

  • PJM faces a 6.8-gigawatt capacity shortfall and proposed an emergency backstop procurement, valued at roughly $20 billion, to secure power.

  • FERC conditionally approved the plan but paused it about five months and ordered revisions so data centers cover the costs they drive.

  • FERC's stated principle is that existing customers should not pay costs attributable to new demand.

  • PJM serves 13 states and Washington, D.C., so the cost-allocation decision reaches a large share of East Coast commercial property.

  • Capacity charges pass through to commercial electric bills, making this regulatory fight a direct NOI question for owners.

What Did FERC Actually Decide?

PJM Interconnection, the grid operator for the Mid-Atlantic and much of the Midwest, asked FERC to approve an emergency backstop procurement to cover a 6.8-gigawatt capacity shortfall driven largely by surging data center demand. FERC conditionally approved the plan but suspended it for roughly five months, directing PJM to revise how the costs are allocated. The regulator's message was that the customers already on the system should not foot the bill for demand that new arrivals create.

The backstop itself is large, an arrangement valued at roughly $20 billion to secure capacity that the normal auction did not deliver. The question FERC pushed back on was not whether to secure the power, but who pays for it. That distinction is the whole story for commercial owners.

Why This Lands on a Commercial Owner's Bill

Capacity charges are the part of an electric bill that pays generators to be available during peak demand, separate from the energy a building actually consumes. In PJM, those charges have climbed to record levels, and they pass through to commercial customers whether or not an owner ever reads an auction result. When a 6.8-gigawatt shortfall gets backfilled through an expensive emergency procurement, someone pays for it in their rates.

If FERC holds the line that data centers cover their own costs, existing commercial customers are partly shielded. If the costs spread across the rate base instead, every owner in PJM helps pay for the data center boom. That is the difference the revised plan will decide.

The Larger Shift This Signals

For years, the cost of serving new large loads was socialized, spread quietly across all ratepayers. The FERC ruling is part of a broader turn toward making the loads that drive grid investment pay for it directly. The same principle is appearing in state rate design, from dedicated data center rate classes to large-load tariffs. For commercial owners, the trend is favorable in direction but unsettled in detail, and the detail is where the dollars are. A plan that assigns costs cleanly to data centers protects other customers; one riddled with exemptions does not.

What Should Owners Do Now?

This is a watch-and-position item more than an act-today one, but it is not passive. Owners in PJM states should track how the revised cost-allocation plan treats existing customers, because it feeds directly into the capacity line on future bills. More broadly, the ruling reinforces the case for controlling the part of the bill an owner can influence. Capacity and demand charges are set by a building's contribution to peak, so demand response, onsite storage and load management reduce exposure regardless of how the regulatory fight resolves. The owners least affected by the who-pays outcome are the ones who have already lowered their own peak.

Frequently Asked Questions

What is a backstop procurement?

It is an emergency mechanism a grid operator uses to secure capacity when the normal auction falls short of what reliability requires. PJM proposed one to cover a 6.8-gigawatt gap. Because it buys power outside the standard process, it tends to be expensive, which is why who pays for it matters so much.

Does this affect owners outside PJM?

Directly, it affects the 13 states and Washington, D.C. that PJM serves. Indirectly, it sets a precedent. Other grid operators and state regulators are wrestling with the same question of who pays for data center demand, and a FERC decision shapes how those debates unfold.

Will this lower my bill?

Not by itself, and not immediately. At best, it prevents data center costs from being added to your rates. The reliable way to lower your own capacity and demand charges is to reduce your building's peak demand through load management, storage or onsite generation.
