German to English Tech/Engineering Energy / Power Generation Setpoint distributor for hydroelectric power station

This is referenced in one block of a block diagram of a setpoint distributor. The whole message reads "Gewinnopt. Verteilung auf die KWs". The KW is assumed to be "Kraftwerk" - power station. If it is any help, the next block reads "aut. Generierung des Fahrplanes" which in turn is linked to "PR-Master". The PR is probably "Primärregelung" - primary control, which is the subject of the entire document.
