We describe a work domain analysis of a hydropower plant that operates in the two independent markets, the electricity market and the irrigation market. Based on the results of a work domain analysis, the authors develop configural displays that represent abstract functions of the hydropower system and that are intended as part of an ecological interface. The displays developed cover three critical segments of hydropower system operations: real time power supply operations, water storage management, and electricity trading. We provide detailed descriptions of the displays and of the expected improvements in control quality caused by the each of the displays.
