A system for optimizing the operation of a plurality of irrigation systems includes at least one control computer, a storage device coupled to the control computer for storing data, a plurality of irrigation device controllers remotely coupled to each of the control computers, and a grid power monitor coupled to the computers for providing power grid demand and usage data. The system may also include GPS and GIS receivers to determine remotely position and soil condition and/or a plurality of sensors located in each of the irrigated fields which transmit soil information directly to the control computers. The control computers each in turn generate priorities of operation for the irrigation systems based on the soil condition information and most economical load operating periods from the electrical power utility. The system is optimized by generating position data for each of the irrigation systems, generating soil condition data at the position of the irrigation system, including current and/or historical weather data and crop information either manually inputted or determined from remote sensors or satellites, and calculating a required period and priority of each irrigation system operation based on the soil conditions at the location of each of the irrigation systems, the historical and/or predicted weather data, the crop data, and finally, automatically scheduling the irrigation system operations based on input from the electrical utility command computer as to the most economical time period for operation.
