NERC Reliability Standards
NERC’s official catalogue identifies current, future-enforcement and other Reliability Standards by family and jurisdiction.
Open official source →Primary-source gateway
Power Reliability Developments
Selected primary-source developments in power-system reliability, regulation, research and emerging large loads. Each entry links directly to the source and provides a brief explanation of its reliability significance.
Page role: Power Reliability Developments is a broader primary-source and research gateway. For selected evolving NERC matters with GR engineering interpretation, use NERC Reliability Change Watch.
Last reviewed: 29 August 2026. Status checked August 29, 2026. This is a selected gateway, not a comprehensive inventory and not a real-time monitoring service. Deadlines and draft text should be reconfirmed on NERC’s official pages.

NERC Large Loads Action Plan
NERC’s central hub for emerging large-load and computational-load actions, including comments on draft standards, registration criteria, SARs, FAQs and related resources.
Open official source →Project 2026-02 Computational Loads — formal posting
Formal comment period through 8:00 p.m. Eastern, September 18, 2026, for draft CLO-001-1, CLO-002-1, CLO-003-1 and limited proposed FAC-001-5 / FAC-002-5 revisions, with ballot pool through September 3 and initial ballots scheduled September 9–18, 2026. Drafts under development—not final or enforceable. Status checked August 29, 2026; reconfirm on NERC’s official pages.
Open official source →Proposed Computational Load registration criteria (Rules of Procedure)
Proposed revisions that would establish Computational Load Owner and Computational Load Operator entity types. Proposed—not yet effective. Applicability depends on final approved criteria and process.
Open official source →Disturbance Performance for Computational Loads — Standard Authorization Request (PDF)
SAR issued for industry comment through September 24, 2026. A SAR frames further standards work; it is not an effective Reliability Standard. Comment matrix: XLSX. Hub: Large Loads Action Plan.
Open SAR PDF →Q2 2026 Large Loads Action Plan update (PDF)
Quarterly Action Plan progress update summarizing NERC’s large-load initiative path. Informational program update—not a Reliability Standard.
Open Q2 2026 update PDF →Large Loads Frequently Asked Questions (PDF)
NERC informational FAQ on large loads / computational loads. FAQ material is explanatory—not an enforceable Reliability Standard.
Open FAQ PDF →Load Modeling Working Group Workshop on Data Center Load Modeling
Two-day workshop: Session 1 September 15, 2026, 12:00–5:00 p.m. Eastern; Session 2 September 16, 2026, 12:00–5:00 p.m. Eastern (Microsoft Teams). Workshop/event—not a ballot or effective standard. Agenda: PDF.
Open official event →Level 3 Essential Action Alert — Computational Loads (PDF)
Issued May 4, 2026. NERC identified seven actions for applicable registered entities. Registered-entity response deadline was August 3, 2026 and has passed; monitor subsequent findings. Does not mean every data center was subject to the Alert. Announcement: NERC newsroom.

Official FERC and NERC-to-FERC sources
FERC & Federal Policy
Official repositories and filings affecting transmission, interconnection and reliability. A proposed rule, filing or FERC direction is not an effective NERC Reliability Standard until the applicable standards process is complete.
FERC eLibrary
Primary repository for FERC orders, notices, filings and docket materials affecting transmission, interconnection and reliability.
Open official source →NERC Filings to FERC — 2026
NERC’s list of 2026 filings to FERC, including proposed Reliability Standards and other regulatory submissions.
Open official source →FERC Order on Computational Load Integration (Docket RD26-7-000) (PDF)
FERC directed NERC to develop and file computational-load Reliability Standards and registration criteria by 31 December 2026. The order does not itself make those future NERC standards effective.
