With currently installed machinery that has certain construction parameters, the increase of efficiency might be achieved by a proper load distribution among generation units, as well as, due to possibly rapid detection of elements whose technical condition may be the cause of efficiency drop. In both cases comprehensive knowledge about current attributes of devices is necessary.
