2021 Standards Grading


The final 2021 grades are provided below.

On March 9, 2016, the Standards Committee (SC) endorsed using an enhanced version of the Independent Expert Review Panel grading tool as the metric to grade all NERC Reliability Standards. The existing grading tool also includes a question on cost effectiveness.

The chair of the SC, two representatives from the Reliability Security and Technical Committee (RSTC), an ERO Regional representative, and NERC staff comprise the PRSRT. The PRSRT has been tasked with initial grading of all currently-enforceable Reliability Standards that have been subject to enforcement in the United States for at least one year. Grading will occur during pre-scheduled meetings and teleconferences that are open to stakeholders and posted on the NERC website. Stakeholder participation allows those with expertise in the implementation of the standards being reviewed to provide input to the PRSRT in their grading.

After the PRSRT completes its initial grading, NERC will post the results for a 45-day stakeholder comment period for PRSRT consideration prior to finalizing the grading. The 2022-2024 Reliability Standards Development Plan will include the final grading, which will be presented to the NERC Board of Trustees (Board).

Standards grading from previous years is used as informational input for periodic review teams, but the standards grading output does not determine the timing or prioritization of period reviews. If a periodic review team recommends changes to a Reliability Standard, the PRSRT will re-grade and post the revised draft standard for stakeholder comment. The results of the re-graded standard will then accompany the standard recommendation when it is presented to the Board for adoption.

The SC leadership and NERC staff are working together to facilitate grading of the 2021-eligible standards​.
