Today, the Federal Energy Regulatory Commission (FERC) issued tailored show cause orders under section 206 of the Federal Power Act to PJM Interconnection, L.L.C. (PJM), Midcontinent Independent System Operator Inc. (MISO), Southwest Power Pool Inc. (SPP), California Independent System Operator (CAISO), ISO New England Inc. (ISO-NE) and New York Independent System Operator (NYISO), together with their transmission owners, directing each region to justify or reform the tariff provisions governing how data centers and other large loads connect to and receive service from the transmission grid. The orders are part of FERC’s broader response to rapidly increasing electricity demand, particularly from data centers and other large loads, and advance the objectives of the Secretary of Energy’s October 2025 Advance Notice of Proposed Rulemaking (ANOPR) by seeking to accelerate “speed to power” while preserving grid reliability, affordability and consumer protections.
