About This Assessment This 2020 Reliability Review Subcommittee Annual Assessment (2020 Annual Report) was developed by the SERC Reliability Review Subcommittee (RRS) in accordance with the Energy Policy Act of 2005 (Title 18, § 39.111 of the Code of Federal Regulations). This assessment also fulfils the ERO’s Rules of Procedure, which instruct the Regions to conduct periodic assessments of the Regional BPS. Development Process This assessment was developed based on data and narrative information collected by SERC from its Registered Entities to independently assess the long-term reliability of the SERC BPS while identifying trends, emerging issues, and potential risks during the ten- year assessment period. The Reliability Review Subcommittee (RRS), at the direction of SERC’s Engineering Committee, supported the development of this assessment through a review process that leveraged the knowledge and experience of system planners, RRS members, SERC staff, and other subject matter experts. This review
process ensures the accuracy and completeness of all data and information. The SERC Engineering Committee reviewed and
approved this assessment. Data Considerations
Forecasts in the 2020 RRS Annual Report are not predictions of what will happen; they are based on information supplied by Registered Entities in February 2020 and updates incorporated prior to publication. The assessment period for the 2020 RRS Annual Report is from 2020 to 2029. The assessment was developed using a consistent approach for projecting future resource adequacy through the application of SERC’s assumptions and assessment methods. SERC’s standardized data reporting and instructions were developed through stakeholder processes to promote data consistency across all the reporting entities. Reliability impacts related to physical and cybersecurity risks are not addressed in this assessment, which is primarily focused on resource adequacy.
