Superseded Standard

IEEE 762-2006

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

This standard provides a methodology for the interpretation of electric generating unit performance data from various systems and to facilitate comparisons among different systems. It also standardizes terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures. This standard is intended to aid the electric power industry in reporting and evaluating electric generating unit reliability, availability, and productivity while recognizing the power industry's needs, including marketplace competition. Included are equations for equivalent demand forced outage rate (EFORd), newly identified outage states, discussion of commercial availability, energy weighted equations for group performance indexes, definitions of outside management control (OMC), pooling methodologies, and time-based calculations for group performance indexes.

P762

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

This document standardizes terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures that recognize the power industry's needs, including system reliability assessment, plant performance benchmarking, and marketplace competition. The standard currently covers conventional generators and variable energy resource (VER) generators. This revision extends the standard to include energy storage, both on a stand-alone basis and in a hybrid configuration with generation.

762-2023

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.

762-1987

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

This standard is intended to aid the electric power industry in reporting and evaluating electric generating unit reliability, availability, and productivity. It was developed to overcome present difficulties in the interpretation of electric generating unit performance data from various systems and to facilitate comparisons among different systems. The standard should also make possible the future exchange o meaningful data among systems in North America and throughout the world. Scope: This document standardizes terminology and indexes for reporting electric generating unit reliability, availability, and productivity performance measures. A generating unit includes all equipment up to the high-voltage terminal of the generator step-up transformer. Reliability in this standard encompasses measures of the ability of generating units to perform their intended function. Availability measures are concerned with the fraction of time a unit is capable of providing service, and account for outage frequency and duration. Productivity measures are concerned with the total power produced by a plant with respect to its potential power production. Therefore, productivity measures consider magnitude of outage as well as frequency and duration of outage. NOTE --This standard was developed for application at the unit level; the definitions are applicable below the unit level in most cases. There are some exceptions, however, such as the definition of in service, which applies only at the unit level. Because of these exceptions, care should be taken when using this standard below the unit level.
