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: 27 September 2026. Status checked September 27, 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 draft standards, registration criteria, SARs, FAQs and related resources. Checked September 27, 2026.
Open official source →Project 2026-02 Computational Loads — standards-development project
NERC’s Project 2026-02 comment period and initial ballots closed September 18, 2026. NERC’s September 19 newsroom described preliminary results as an initial-ballot pass; the project page now posts ballot statistics while the drafting team reviews comments and determines next steps. The drafts are not approved, filed with FERC or effective Reliability Standards.
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. The August 19–September 18, 2026 comment period has closed. NERC states it reviewed comments and will post its consideration of comments soon. Proposed—not yet effective. Closing the period does not approve the criteria.
Open official source →Disturbance Performance for Computational Loads — Standard Authorization Request (PDF)
Comments were requested through September 24, 2026. That period has closed. As of September 27, 2026, the Action Plan hub does not post a Standards Committee disposition of this SAR. A SAR is not an effective Reliability Standard. Comment matrix: XLSX. Hub: Large Loads Action Plan.
Open SAR PDF →Two additional computational-load SARs — posted for comment
NERC posted two additional computational-load SARs for comment through October 22, 2026: one addressing event reporting, model validation and model quality; the other addressing computational-load-loss studies. They are separate from Project 2026-02 and the closed Disturbance Performance SAR. They are proposed SARs, not effective Reliability Standards.
Open NERC requests for comment →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
The two-day workshop was held: Session 1 September 15, 2026, and Session 2 September 16, 2026, 12:00–5:00 p.m. Eastern each day (Microsoft Teams). The Large Loads Action Plan now lists it as a prior event. It was a workshop, not a ballot or an 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.

Reliability R&D
Research & Development
Major reliability research programs, partnerships, methods and tools. Research and guidance are not enforceable Reliability Standards.
DOE Grid Modernization Initiative
DOE and national-laboratory research developing technologies and methods to measure, analyze, predict, protect and control the modern electric grid.

IEA examines how digital technologies, including AI, can improve grid planning, construction, maintenance, operation, forecasting, situational awareness and resilience while making better use of existing assets. It also states that network expansion remains essential. This international report is not a U.S. Reliability Standard, and inclusion does not imply affiliation or endorsement.
Open IEA report →DOE announcement — data-center electricity demand
DOE announcement of the Lawrence Berkeley National Laboratory 2024 Report on U.S. Data Center Energy Use.
