IEEE Standard Definitions for Use in Reporting Electric Generating Unit Reliability, Availability, and Productivity

Outlined in this document are standardized terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures that recognize the power industry’s needs, including marketplace competition. This standard also includes equations for equivalent demand forced outage rate (EFORd), newly identified outage states, energy weighted equations for group performance indexes, definitions of outside management control (OMC), pooling methodologies, and time-based calculations for group performance indexes. It includes consideration of variable energy resource units and resource unavailability and new indexes appropriate for that purpose.
