FERC orders grid operators to fast-track AI data center connections; 60-day deadline to justify or rewrite tariffs

On June 18, the Federal Energy Regulatory Commission issued tailored show-cause orders under Section 206 of the Federal Power Act to all six regional grid operators (PJM, MISO, Southwest Power Pool, CAISO, ISO New England, NYISO), ordering them to either justify why their current tariffs for large-load interconnection remain just and reasonable, or file tariff changes addressing commission-identified issues. Grid operators and transmission owners have 60 days to respond and 30 days to submit detailed reports on how they intend to ensure adequate generation capacity for AI data centers and other large energy users. This represents one of the most significant federal regulatory actions to modernize electric markets and accelerate AI infrastructure deployment.

FERC's orders directly target five categories of reform: developing efficient transmission service application/study processes with consideration of alternative technologies; preventing cost shifting and requiring cost transparency; accommodating co-location agreements and behind-the-meter generation; providing new transmission services for flexible large loads; and developing a process to study generating facilities serving electrically proximate or co-located loads. Data centers will bear the full cost of grid upgrades under the framework, protecting ratepayers from cost shifting. The action responds directly to October 2025 guidance from Energy Secretary Chris Wright, who argued that delays in data center grid connections threaten U.S. competitiveness in AI.

For architects planning large-scale AI infrastructure buildouts, this FERC action removes one major procedural bottleneck: rather than multi-year rulemaking cycles, grid operators now face 60-day hard deadlines. However, the orders do not address the underlying generation capacity shortage; new power plants themselves face lengthy interconnection queues. Data center capacity planning should account for state-level variation—FERC left states in control of retail rates and conditions, and grid operators' responses (due in 60 days) will shape regional interconnection economics. The framing of AI infrastructure as a national security asset suggests sustained regulatory momentum.
