The constraint moves from "how much" power to "how to connect it"
The power problem for AI data centers is no longer only "is there enough." How to connect large loads to the grid reliably and quickly — those procedures and rules have become a new constraint. PJM, one of the largest US grid operators, has moved head-on to address it.
For siting and procurement, this matters. PJM's footprint serves 67 million consumers, and supply-demand tightness is pushing up wholesale power costs. How the connection rules for large loads shape up is a leading indicator of data-center siting and cost.
PJM's integration plan — January 2026, 12 proposals
On January 16, 2026, the PJM Board announced a set of actions to integrate large-load customers such as data centers. An accelerated stakeholder process produced 12 proposals. The plan has three pillars — direct FERC filings, immediately implementable changes to PJM's internal rules, and an additional stakeholder process. The PJM Board chair framed data-center integration as "not a yes-or-no question." Not whether to connect, but how to connect while preserving reliability.
The tightness will not wait. PJM immediately launched an emergency procurement process for backstop generation, securing supply in parallel.
FERC filings — price-collar extension and faster interconnection
On February 27, 2026, PJM made two regulatory filings at FERC. One is extending the capacity-auction price collar; the other is expediting interconnection. The price collar is set with a cap of about $325/MW-day and a floor of about $175/MW-day, curbing swings in capacity prices. Capacity auctions planned for mid- and late-2026 aim to secure supply for the 2028/2029 and 2029/2030 delivery years — building future capacity years ahead while preserving price predictability.
New ways to connect
The heart of the rules is providing "new entrances" to connect large loads quickly. A "bring your own generation" option, where large loads bring their own power, is added, opening a path for customers to secure their own generation and connect. It also creates an "expedited interconnection track" for state-led generation projects. However, this track is conditioned on an in-service-date commitment and support from state siting authorities — a check to balance speed and certainty.
Political backing
The reform has broad support. All 13 governors in PJM's footprint, the White House National Energy Dominance Council, and the DOE back the reforms in principle. Political backing from state and federal levels joins the grid operator's technical judgment. It shows data-center power connection is now a national priority, not a single operator's discretion.
How to read the grid constraint
PJM large-load rule-building essentials
01
What happened
The PJM Board announced a large-load integration plan in Jan 2026 (12 proposals). On Feb 27 it filed at FERC to extend the price collar and expedite interconnection.
02
Price collar
Cap ~$325 / floor ~$175 per MW-day curbs capacity-price swings. Secures supply for the 2028/29 and 2029/30 delivery years.
03
New entrances
Adds bring-your-own-generation (BYOG) and an expedited track for state-led generation — conditioned on in-service dates and state authority support.
04
Broad support
All 13 governors, the White House, and the DOE back it in principle. Data-center power connection has become a national priority.
Business impact and checkpoints
From a siting and procurement view: (1) if your data-center candidates are in PJM's footprint, whether you can meet the requirements of the expedited track or bring-your-own-generation (in-service-date commitment, state authority support); (2) how far the price collar raises predictability of capacity cost years out; and (3) whether you are tracking FERC's decision and timing — the filings are still pending approval. The AI data-center constraint has shifted from "is there enough power" to "how to connect it reliably." The grid operator's rule-building is worth tracking as a leading indicator of siting and cost.
