FERC Orders Six Grid Operators to Reconsider Rules for Data Centers and Other Large Power Users
The Federal Energy Regulatory Commission on June 18 ordered six regional grid operators to explain or revise how they connect data centers, manufacturing facilities and other large electricity users to the power grid.
The tailored show-cause orders, issued under Section 206 of the Federal Power Act, open a federal review of the rules used by each of the six regional transmission organizations and independent system operators under FERC jurisdiction.
FERC said the action is intended to speed the integration of very large electricity users while protecting grid reliability and addressing how the costs of new infrastructure are allocated. The move comes as artificial-intelligence facilities and industrial projects seek access to increasingly limited electricity supplies.
What FERC is asking grid operators to do
A show-cause order requires the recipient to explain why its existing practices should remain in place or to propose changes. In this case, FERC is focusing on the procedures and requirements used when large new customers seek to connect to the electric system.
The proceeding covers data centers, manufacturing facilities and other power-intensive users. These projects can require substantially more electricity than ordinary commercial customers, making the timing and design of their connections important to utilities, grid operators and customers already using the system.
FERC’s action is not a final national interconnection rule. The six operators have been directed to respond, and the eventual reforms, timelines and cost-allocation requirements had not been decided when the orders were issued.
Why the decision matters
The orders address two connected questions: how quickly the grid can accommodate new demand and how to prevent the risks or expenses associated with that demand from being shifted unfairly to existing customers.
FERC described the orders as a response to rapidly rising electricity demand. Reuters reported that the commission is pushing grid operators to consider protocols for connecting very large users more quickly, while also examining concerns about grid risk and whether new infrastructure costs could be passed to customers that did not create the demand.
The outcome could affect the pace at which data centers and industrial facilities receive power, as well as the conditions developers must meet before connecting. It could also shape how regional operators evaluate reliability, transmission needs and payments for upgrades required by new large loads.
The orders do not establish that household ratepayers will ultimately pay any portion of those costs. That question remains part of the broader cost-allocation issue the proceedings are intended to address.
Broader transmission pressure
The FERC action follows federal attention to the need for more transmission capacity. The Energy Department’s Office of Electricity released a draft 2026 National Transmission Needs Study that identified an urgent need for additional transmission infrastructure to support reliability and security.
The department opened a 60-day public-comment period on the draft study and planned public roundtables. The study is separate from FERC’s show-cause orders, but both actions reflect the pressure created by changing electricity demand and the need to expand or reinforce the grid.
What happens next
The six regional grid operators must address FERC’s directives through the commission’s Section 206 proceedings. Their responses will help determine whether existing connection rules are adequate or whether revisions are required.
FERC’s June 18 action therefore begins a regulatory process rather than delivering a final answer. The central issues—how rapidly large loads should be connected, what reliability protections should apply and who should pay for related grid work—will be resolved through the proceedings that follow.
