IEEE 762-1987

IEEE 762-1987 defines standard terminology for reporting electric generating unit reliability, availability, and productivity. It is aimed at power and energy applications where consistent definitions are needed to compare operating performance across generating units and reporting periods. By aligning key terms and measures, this standard helps reduce ambiguity in plant records, performance summaries, and technical communication. As a superseded document, IEEE 762-1987 remains relevant for understanding older reporting practices and legacy data.

About IEEE 762-1987

IEEE 762-1987 provides definitions used in the reporting of electric generating unit reliability, availability, and productivity. In practical terms, it supports a common vocabulary for describing whether a unit was in service, available, unavailable, or otherwise constrained during a reporting interval. That consistency is important when comparing operating results, preparing technical documentation, or reviewing historical performance. The standard is especially useful in settings where precise reporting language affects engineering analysis, asset management, and internal compliance processes.

Where is IEEE 762-1987 used?

This standard is most relevant in utility and generation environments that track unit-level performance for coal, gas, nuclear, hydro, or other power plants. It may be used in operations reporting, reliability studies, availability calculations, and productivity reviews tied to generating equipment and plant records. IEEE 762-1987 is also helpful when organizations compare results across fleets or reconcile legacy reports that rely on older definitions. Its terminology supports consistent communication between operations, maintenance, planning, and engineering teams.

Importance in practice

IEEE 762-1987 matters because reliability and availability reporting depends on clear, consistent definitions. Without shared terminology, performance figures can be difficult to compare or defend during audits, internal reviews, or procurement assessments. The standard helps organizations reduce reporting disputes, improve data quality, and maintain traceable records for generating unit performance. In practice, that supports more reliable benchmarking, better maintenance planning, and lower risk when evaluating operating history or technical compliance.
