FERC gives NERC until December to write grid rules for AI loads

The Federal Energy Regulatory Commission directed the North American Electric Reliability Corporation on July 16, 2026, to develop and submit new or modified reliability standards for computational loads connected to the nation’s bulk-power system.

NERC must submit both the proposed reliability standards and related changes to its Rules of Procedure by December 31, 2026. The action, taken in FERC Docket RD26-7-000, addresses reliability risks associated with rapidly growing large electricity users, including artificial-intelligence and cryptocurrency data centers.

Why computational loads raise a reliability issue

The concern is not only how much electricity these facilities consume. Large computational loads can also change their demand very quickly. A facility may reduce or shift power use within seconds, creating a sudden imbalance that grid operators must manage through generation, transmission and voltage or frequency controls.

NERC’s large-load work identifies rapidly expanding computational facilities as a growing operational issue and points to customer-initiated load reductions and oscillations that can occur on very short time scales.

A separate July 22 event in the PJM Interconnection region illustrated why sudden load changes are receiving attention. Reuters reported that more than 3 gigawatts of data-center demand abruptly went offline after a transmission-line outage in northern Virginia. PJM reported a change in grid frequency but said the event did not affect reliability. The event occurred after FERC’s July 16 action and was not identified as the reason for that order.

What FERC ordered

FERC directed NERC to develop and file new or modified reliability standards addressing risks tied to integrating computational loads into the Bulk-Power System. The commission also directed NERC to propose revisions to its Rules of Procedure, including criteria for determining which computational-load entities should be included in the applicable registry.

That registry question matters because the July action does not automatically make every data center a NERC-registered entity. The criteria still have to be developed, filed and reviewed.

FERC’s public meeting page says its summaries are general synopses and are not substitutes for the individual Commission orders. FERC’s July 16 action notice separately confirms that the commission acted on the computational-load item under Docket RD26-7-000.

What does not change immediately

The July 16 action is a directive to develop and file standards. It is not a final nationwide operating rule that immediately imposes a complete new compliance regime on all AI data centers.

After NERC files its proposals, FERC will review them. The commission could approve, reject or require changes to the filings before any new standards take effect.

Why utilities and customers should watch

Future standards could affect how large computational facilities connect to the grid, what operating information they provide, how they coordinate with utilities and how they respond during reliability events.

Utilities and regional grid operators may need to account for both sustained demand growth and fast changes in demand when planning transmission, generation and system controls. Data-center developers could face additional technical studies, communications requirements or operating obligations if later proposals are approved.

Cost allocation is another issue to watch. The July action itself does not create an immediate nationwide increase in household electric bills. Later standards, interconnection decisions, transmission planning and rate proceedings could raise questions about which costs are assigned to large new customers and which are shared more broadly, but those outcomes remain unresolved.

What happens next

NERC’s first major deadline is December 31, 2026, for the proposed reliability standards and Rules of Procedure revisions. NERC’s broader large-load work also identifies a March 2027 milestone for an additional action plan. FERC review and possible revisions would follow.

For now, the practical takeaway is narrower: federal regulators are moving computational loads into the formal reliability discussion, but the detailed rules governing AI-era data centers have not yet been finalized.
