Address gaps in resource accreditation to incentivize resources to be available during times of need.

This issue is inclusive of the 2020 RASC High Priorities and IMM State-of-the-Market Recommendations::

  • More effective outage rate accreditation
  • Create accreditation which incents desired performance
  • Forward capacity accreditation for renewable (IR095) and use-limited (IR096) resources
  • Seasonal/monthly outage modeling
  • Expand the use of diversity contracts
  • Solar capacity credit
  • Hybrid capacity accreditation
  • IMM 2017-7
  • IMM 2018-5

 This issue was identified in 2018 as a Phase 2 issue of Resource Availability and Need (IR025) and was redefined ahead of the 2021 Integrated Roadmap Work Plan prioritization in an effort to further break out RAN projects.

Updated the issue description to include additional issue components. Also deleted the previous issue description from 2019, which stated: Develop a holistic solution that provides sufficient granularity for energy needs to facilitate efficient conversion of committed capacity to energy to serve load for all hours of the year. The recommended approach is to build off of RAN Phases 1 & 2 and evaluate a seasonal resource adequacy construct and implement if necessary. In parallel, work with the Market Subcommittee’s Phase 3 assignment to improve market incentives for resource availability to meet daily and variable energy needs.

01/08/2020

MISO presented highlighted gaps in the current LMR accreditation and LOLE modeling and proposed strawman proposals. Due to the relationship between capacity accreditation and seasonal resource adequacy, the near term focus shifted to smaller, incremental improvements.
