Equivalent Availability Factor

Equivalent Availability Factor

KPI Details

Equivalent Availability Factor measures the effectiveness and overall reliability of energy production facilities operated by the company. A relatively low value (versus other similar production facilities) may indicate that the facility is not configured to run at full capacity for long periods of time or experiences a large amount of idle time, which can be related to poor equipment performance (or quality), subpar facility management and maintenance processes, and/or ineffective facility design.

KPI Definition

The amount of time where energy production facilities are able to produce energy at full capacity as a percentage of total time during the measurement period.

KPI Best Practices

• Adopt comprehensive preventative maintenance programs to minimize downtime
• purchasing departments that balance cost considerations with performance and longterm reliability
• regularly train employees on equipment use and ways to improve production capacity

KPI Calculation Instructions Equivalent Availability Factor?

Two values are used to calculate this KPI: (1) the amount of time that energy production facilities are able to run at full capacity, and (2) the total amount of time in the measurement period. Periods of time where the facility is still able to produce energy, but not at full capacity (i.e., only partial capacity available) should not be included in the numerator for this calculation. This metric should be segmented and analyzed separately for each facility and generation technology (solar, etc.).

KPI Formula :

(Amount of Time Energy Production Facilities are Able to Run at Full Capacity / Total Amount of Time in Measurement Period) * 100
