Reliability Assessment Subcommittee (RAS)

​All previous documents under the Planning Committee can be found here: RAS Documents.

The Reliability Assessment Subcommittee (RAS) reviews, assesses, and reports on the overall reliability (adequacy and security) of bulk power systems, both existing and as planned. Those reviews and assessments verify that each assessment area conforms to its own planning criteria, guides and the applicable NERC Reliability Standards. The Reliability Assessment Subcommittee’s Review and Assessment Process is described in ERO Reliability Assessment Process Document. Further guidance for reliability assessment is provided in the NERC Rules of Procedure: Section 800.
