U.S. FERC Overhauls Grid Rules for Large Energy Users
The Federal Energy Regulatory Commission (FERC) has ordered six major U.S. regional grid operators to justify or reform their tariff rules governing the connection of large electricity users such as data centers and industrial facilities.
The directive applies to PJM Interconnection, Midcontinent Independent System Operator (MISO), Southwest Power Pool (SPP), California ISO (CAISO), ISO New England (ISO-NE), and New York ISO (NYISO).
Each operator has 60 days to either demonstrate that existing rules remain “just and reasonable” or submit tariff changes addressing how large loads connect to the grid. Within 30 days, they must also submit reports outlining how they will ensure sufficient generation to serve existing and new large demand.
The Commission said the action is intended to speed up interconnection processes while maintaining reliability and limiting cost shifts to existing customers. It identified five reform areas, including transmission study processes, cost transparency, co-location rules, flexible service options, and evaluation of generation serving nearby large loads.
Announcing the decision, FERC Chairman Laura V. Swett said:
“We are setting the stage for a resilient, reliable, and forward-thinking grid that empowers communities and safeguards consumers by transforming the way large energy users access the grid. It also is critical that FERC provide certainty for investors by directing the markets to protect existing deals and unlock opportunities for technological advancement and economic expansion. We can facilitate both, which is exactly what we did today.”
The move comes as U.S. electricity demand grows rapidly, driven by data centers, electrification, and industrial expansion.
