Explain the concept of 'equivalent availability' as a key performance indicator (KPI) for industrial plants.

Equivalent availability (EA) is a key performance indicator (KPI) used to measure the actual operational availability of an industrial plant or equipment, taking into account both planned and unplanned downtime, as well as derated operating conditions. It represents the percentage of time that the plant or equipment is capable of operating at its full rated capacity. Unlike simple availability, which only considers whether a system is running or not, equivalent availability accounts for partial load operation. The formula for calculating equivalent availability is: EA = (Energy Produced / Energy that could have been pr....
