NERC Grid Rules Clear Ballot With 36-Month Recorder Delay

The North American Electric Reliability Corporation announced on 15 October 2026 that three new reliability standards for data centres, artificial intelligence facilities and cryptocurrency mining operations had passed their final stakeholder ballot. The package, Project 2026-02, would apply to computational-load sites with at least 50 MW of total connected load supplied through electrical equipment connected at 100 kV or above.

It is not in force. The standards and their implementation plans go to NERC's Board of Trustees, expected in the fourth quarter, and then to the Federal Energy Regulatory Commission. FERC directed NERC on 16 July 2026 to file initial computational-load standards by 31 December 2026. On 8 October the NERC board approved changes to its Rules of Procedure creating two new functional entity types, the Computational Load Owner and the Computational Load Operator.

The instruction a data centre would have to obey

The sharpest provision is Requirement R8 of CLO-002-1. A computational-load operator would have to comply with an operating instruction from its transmission operator, balancing authority or reliability coordinator unless the action could not be physically implemented or would breach safety, equipment, regulatory or statutory requirements. An operator that cannot comply must notify whoever issued the instruction, and staff who take oral instructions need initial training in confirming them or asking for a repetition.

CLO-001-1 handles the modelling that makes such an instruction meaningful. Owners would supply planning-model data covering tripping, ride-through and recovery settings after disturbances, plus the amount and expected use of their IT infrastructure, and file verification showing the model matches installed equipment. Updates are due within 180 days of any hardware, software, firmware or setting change that alters dynamic response.

Three years to fit the recorders

CLO-003-1, covering protection coordination and disturbance monitoring, carries the longest transition. Sites already in service when it takes effect would have 36 months to meet its recording requirements for breaker status, fault recordings and continuous dynamic disturbance data. Sites entering service later get until 15 months after the effective date or their in-service date, whichever is later, and protection-coordination duties begin at nine months. NERC's implementation plan attributes the schedule to equipment procurement, installation and the outages needed to fit it.

That is a long wait for the measurements the package exists to collect. NERC wrote these standards after computational loads dropped off the system without warning or swung demand rapidly, which prompted a Level 3 Essential Action Alert in May 2026 setting out seven immediate actions for grid entities. The scale behind it: NERC forecast in January 2026 that summer peak demand across the bulk power system would rise by 224 GW over ten years, a 24 per cent increase on the 2025 peak.

These standards are the technical half of a fight Parallax Nexus has covered through its regulatory half. FERC rejected the core of PJM's data centre connection plan earlier this month, and MISO has asked the commission to fast-track loads above 200 MW with the generation to serve them. Those dockets settle who pays and who connects. Project 2026-02 settles what a connected site owes the operator afterwards.

Who answers for a tenant's servers

The hardest question in drafting was multitenant sites. The Data Center Coalition argued that a site operator may have no authority over a tenant's equipment, no access to its information and no technical ability to change its consumption, and that data requests should not compel information outside an owner's control. The drafting team replied that no dedicated on-site operating organisation is required and a centralised or shared function can be the accountable operator. It kept the existing exceptions rather than adding the contractual and third-party-control carve-outs the coalition sought. Meta filed comments in the same round.

The applicability threshold moved during drafting, up from 20 MW and 60 kV in NERC's initial registration proposal. The judgment worth stating plainly is that the trade bought the package its ballot: a narrower scope with obligations attached is worth more than a wide one that fails a vote. It also leaves mid-sized sites, and anything fed below 100 kV, inside a regional patchwork instead, with the Public Utility Commission of Texas reaching ERCOT sites at 75 MW. How many sites fall inside is not known, because registration determinations would be made case by case by NERC and the relevant Regional Entities.
