RM26-4 was an active federal proceeding scheduled for June 18 action; no post-meeting controlling outcome was located at cutoff.

Executive summary

Read the conclusion before the archive.

  1. RM26-4 was an active federal proceeding scheduled for June 18 action; no post-meeting controlling outcome was located at cutoff.
  2. The verified path stops at RULEMAKING / AGENDA; the next transition remains bounded by the public record.
  3. No final rule, obligation, schedule or project-access outcome.

CLM-0053 · interpretation

No single U.S. “grid interconnection” state applies to all large loads: retail load service/interconnection, transmission service, generator interconnection, co-location, and behind-the-meter arrangements use different actors, instruments, studies, and jurisdictional pathways.

CLM-0054 · legal status

At the Pass 03 cutoff, FERC Docket RM26-4 remained open and was listed for the June 18, 2026 Commission meeting later that day; no post-meeting action was publicly available by 05:04:45Z.

CLM-0073 · interpretation

Public records commonly disclose process rules, aggregate queues, forecasts, orders, and selected milestones, while project-specific models, study inputs, upgrade costs, service agreements, customer identities, and operational settings may be confidential, redacted, or CEII-protected.

Claim ceiling
Unknown or confidential fields must remain gaps; no inference or sensitive aggregation.

CLM-0075 · interpretation

No uniform, final, mandatory national large-load interconnection and performance standard was established in the public record by the cutoff: RM26-4 was pending, NERC’s guideline was non-mandatory, and regional approaches remained heterogeneous.

Claim ceiling
Bounded to inspected public record and cutoff; later action triggers reopening.

CLM-0076 · interpretation

Pass 03 located no project-specific public evidence that upgrades any bounded project to C14 energization, C15 commissioning, C16 installed IT, C17 operating cluster, or later economic states; process and aggregate records cannot supply those transitions.

Contrary evidence and competing mechanisms

CTR-0017 · Policy and data uncertainty

A single national “interconnection queue” model does not describe current large-load pathways.

Evidence result:CAISO, MISO, ERCOT, PJM, SPP, NYISO and ISO-NE assign different roles to utilities, RTO/ISOs, transmission service, forecasting and generator interconnection.

Ceiling effect:Prohibits uniform national process claims.

CTR-0022 · Existing reliability rules are complete and uniform

NERC identifies standardization, model, data, commissioning and registration gaps, while its 2026 guideline remains non-mandatory.

Evidence result:Gap assessment and current standards-development status show the framework is incomplete and evolving.

Ceiling effect:Prohibits claims of a complete mandatory national standard.

CTR-0057 · Policy and data uncertainty

An agenda commitment to act does not establish the content, timing or effect of a final federal action.

Evidence result:RM26-4 was publicly scheduled for the June 18 meeting, but no post-meeting controlling record was located at the cutoff used for this pass.

Ceiling effect:Federal cluster remains process-only.

CTR-0060 · Forecast inflation / pipeline attrition

Aggregate requests and preliminary forecasts materially overstate what can be counted as realized operating demand.

Evidence result:ERCOT separately reports request-queue/status information and a preliminary planning forecast; neither is project realization.

Ceiling effect:No summation; cohort C7 only.

CTR-0062 · Private-risk allocation

Tariff security can shift some risk to large customers without proving complete insulation of other customers.

Evidence result:Virginia GS-5 includes long obligations, minimum billing and collateral, while future allocation and implementation still matter.

Ceiling effect:Partial risk-shift claim only.

CTR-0063 · Local veto and process risk

Prior local approval can be invalidated for process defects and remain uncertain during further appeal.

Evidence result:Virginia intermediate appellate opinion held three Digital Gateway rezonings void ab initio; appeal remains pending.

Ceiling effect:C21 legal state; not final cancellation.

Public-record gaps

NEG-0010

Question checked:Was the June 18, 2026 FERC RM26-4 outcome available at the program cutoff?

No; meeting was scheduled for the next morning Eastern time.

Implication:CURRENT-STATUS GAP; immediate reopen trigger.

NEG-0019

Question checked:Did FERC issue a public RM26-4 action before the Pass 03 cutoff?

CURRENT-STATUS GAP. The matter was scheduled later on June 18; no post-meeting outcome was available by 05:04:45Z.

Implication:Do not describe a final or proposed rule beyond the documented ANOPR/current docket state.

NEG-0021

Question checked:Does a uniform final mandatory national large-load interconnection/performance standard exist at cutoff?

NO IN INSPECTED PUBLIC RECORD. Federal rulemaking was pending, NERC guidance was non-mandatory, and regional frameworks differed.

Implication:Use jurisdiction- and instrument-specific claims only.

NEG-0022

Question checked:Can ERCOT aggregate large-load interest be reconciled to project-level approved, deliverable and energized MW?

SOURCE GAP. Aggregate interest/process evidence does not provide a complete public project-level C7–C17 crosswalk.

Implication:No project realization ratio or operating total from aggregate request figures.

NEG-0023

Question checked:Is a standardized public MISO large-load queue with project-level load states available in inspected sources?

SOURCE GAP. Public materials describe initiatives and generator interconnection, not a complete standardized load-project state ledger.

Implication:Do not infer project counts, MW approvals or energization.

06 · Record maintenance

What would justify reopening this report.

Updates require a documented evidence delta. Passage of time, repetition of an announcement or a portfolio-level disclosure is not enough.

What could change this record

  • OIR-0001 · FERC issues any action, order, notice, transcript, or release in RM26-4 after the June 18, 2026 meeting.

    Required update: Retrieve official post-meeting action/order/transcript; record exact docket/order, effective/proposed status, affected pathways, and evidence delta.

  • OIR-0006 · NERC changes the guideline, closes the alert, advances Project 2026-02, changes registration, or FERC approves a standard.

    Required update: Version-control document; distinguish voluntary from mandatory; update exact obligations and effective dates.

  • OIR-0019 · Any bounded project receives a material cancellation, downsizing, land/permit decision, construction milestone, service agreement, energization, commissioning, phase redefinition, or portfolio-capacity reconciliation.

    Required update: Create dated state observation; preserve prior state; record supersession/overlap; update affected capacity fields without borrowing later-state language.

  • OIR-0020 · Public evidence provides measured operating load, commissioned IT capacity, customer-use, utilization, revenue/economic incidence, or independent verification for a C17 project.

    Required update: Verify unit, period, site boundary and source function; upgrade only the supported state; preserve contrary evidence and C18–C20 distinctions.

  • OIR-0022 · An RTO/ISO, transmission owner, state regulator, or FERC adopts, modifies, stays, or withdraws a large-load interconnection, co-location, transmission-service, or technical-requirement framework.

    Required update: Record legal instrument, procedural/effective status, exact locator, supersession and limits; do not borrow project states.

  • OIR-0023 · A public, project-level large-load dataset or executed agreement resolves request, study, upgrade, contract, deliverability, energization, or commissioning states for an aggregate regional cohort.

    Required update: Create dated project state observations, preserve units and confidentiality, and upgrade only directly supported transitions.

  • OIR-0056 · New cross-case evidence materially changes a rival win or adaptation outcome.

    Required update: Update only affected case and preserve mechanism/outcome distinction.
