Power-grid overseers voted to adopt reliability rules for AI data centers and crypto miners

The North American Electric Reliability Corporation’s Board of Trustees has voted to adopt reliability standards for AI data centers and other computational loads, including cryptocurrency mining operations. Utility Dive reported the vote in an October 27, 2026 update. The standards now go to the Federal Energy Regulatory Commission for approval.

Until now, large data centers and crypto miners have connected to the transmission grid without mandatory reliability rules of their own. Several have dropped hundreds of megawatts of demand in seconds, Planners worry about the pattern because demand that vanishes in seconds forces generators and operators to respond to a sudden surplus, and the board’s action is the industry regulator’s answer to that pattern.

Which sites the standards cover

The standards apply to computational loads of 50 MW or greater connected at 100 kV or higher, according to Utility Dive. POWER magazine reported that NERC raised those thresholds from an initial proposal of 20 MW and 60 kV after stakeholder comments, and that the scope reaches qualifying data centers, AI facilities and cryptocurrency operations. The rules are meant to establish requirements for reliable integration of large computational loads into the bulk power system.

NERC’s Project 2026-02 page tracks the package, which includes new standards identified as CLO-001-1 and CLO-002-1. The first, available in its final ballot text, sets modeling data, verification and reporting procedures for planning cases. The second, in a separate final ballot document, requires transmission operators, balancing authorities and reliability coordinators to have the site data they need and predefined communications protocols.

A third area covers load protection coordination and disturbance monitoring. The package does not set minimum voltage or frequency ride-through requirements; POWER reported that CLO-001-1 would instead require owners to provide modeling data on ride-through capabilities, while separate standard authorization requests on disturbance performance remain in stakeholder review.

The package passed the final stakeholder ballot as three new standards and two revised ones, and the reporting gives no vote tallies. Its subject areas, according to Utility Dive, are interconnection studies and modeling, operational data and communications, and load protection coordination and disturbance monitoring. Each is aimed at giving transmission planners and operators the same information about a large computational site that they already expect from a power plant.

The load-loss events behind the rules

The standards follow a Level 3 alert that NERC issued in May 2026 after data centers dropped load or oscillated demand rapidly. Utility Dive’s coverage of that alert describes the seven actions grid entities must take while permanent rules are developed.

The evidence is concrete. POWER reported that a January 2026 NERC review examined 26 events in the Texas grid operator’s territory between January 2023 and September 2025. Each involved a load reduction over 100 MW, and facilities lost between 17 percent and 95 percent of their pre-disturbance consumption. The alert came after data centers dropped load or oscillated demand rapidly, and it obliges grid entities to act before any permanent rule exists.

Demand growth raises the stakes. NERC projected in January that summer peak demand will grow by 224 GW over ten years, a 24 percent increase from 2025, with data centers a main driver, according to Utility Dive’s coverage of the forecast. That growth explains why registration matters: a category of customer that historically had no obligations under NERC rules is being brought into the framework as owners and operators.

From board vote to FERC filing

Stakeholders approved the standards on a final NERC ballot on October 15, 2026, and the board’s vote followed. NERC’s own newsroom announcement describes the adoption of reliability standards for computational loads alongside revisions to the Standard Processes Manual, which passed initial ballot with strong stakeholder support. NERC will file the standards with FERC and coordinate with authorities in Canada on next steps.

The calendar is already set. POWER reported that a July 16 FERC order requires NERC to file the initial standards and registration criteria by December 31, 2026, and a work plan for additional standards by March 1, 2027. On October 8 the board approved Rules of Procedure revisions creating two registration categories, Computational Load Owner and Computational Load Operator. Those dates leave little room between the board vote and the first filing, and the registration categories approved on October 8 give NERC the legal hook to place data center and crypto mining operators on its compliance rolls once FERC acts. Operators of qualifying sites should expect to supply modeling data, site contact information and communications protocols to their transmission operators and reliability coordinators as the requirements take effect.

The unresolved piece is performance during disturbances. With ride-through requirements still in stakeholder review, the first rules decide who is registered and what data must be shared, while the harder question of how a 50 MW site must behave during a fault has yet to be settled. Texas is a useful test case because its grid operator supplied many of the load-loss events, and whether the same 50 MW and 100 kV thresholds capture the sites that cause trouble is a question FERC review may probe.
