Reliability Standards Under Development

The Reliability Standards Under Development page provides access to all projects including: Reliability Standards, Standard Authorization Requests, Periodic Reviews, and Interpretations.

Once Reliability Standard(s) are adopted by the NERC Board of Trustees and filed with FERC, the associated project is moved to the Archived Reliability Standards Under Development page and the Reliability Standard(s) are updated throughout the website including US Reliability Standards, the Complete Set of Reliability Standards and Align allowing for updates to the US Effective Date Status Functional Applicability site.

Prioritization

NERC Standards Projects have been increasing in quantity; coinciding with the increasing pace of technology changes in our industry and the issuance of FERC directives. The criteria for high, medium and low priority projects are included in the slide deck below.

Prioritization Slide Deck

FERC Order No. 901, Inverter-based Resource (IBR), and Distributed Energy Resources (DER)

FERC Order 901 was issued under Docket No. RM22-12-000 on October 19, 2023 and includes many directives instructing NERC to modify or create new Reliability Standards that will address a variety of IBR-related issues. Multiple NERC Standards Projects will be developed through 2026 that are associated with these directives. Detailed information and updates will be maintained on this page and within each associated Standards Project.

Group Health Plan Transparency in Coverage Files*

*This link leads to the machine-readable files that are made available in response to the federal Transparency in Coverage Rule and includes negotiated service rates and out-of-network allowed amounts between health plans and healthcare providers. The machine-readable files are formatted to allow researchers, regulators, and application developers to more easily access and analyze data.
