Hydro Performance Indicators

Most hydro plants have acquired many years of archival data containing detailed operating information that include power, flow, blade, head, and gate data on a unit basis. These data can provide a wealth of information for optimizing system and plant efficiency and for improving the reliability of unit components and unit instrumentation.

One use for these data is to compute hydro performance indicators that quantify energy and revenue gains achievable with improved system and plant dispatch, with improved unit characteristics, and with improved trash rack cleaning. Examples from some of these analyses are presented in the charts below.
