Abstract: We have determined the effect of time of use electrical energy prices, as proposed by the Salt River Project, on groundwater irrigation costs for cotton/wheat farms. We have utilized a simulated 600 ac. farm in the analysis. Energy-demand schedules are developed for a representative farm with given cropping pattern, irrigation schedules, and pumping energy requirements. Inherent in the development of the data are assumptions of irrigation method and efficiency and of pumping depth and efficiency. We find that the proposed SRP TOD rates would result in lower pumping costs if some pumping can be shifted to off-peak rate periods. Water conservation could result in additional economic benefits. The results appear to be case-specific. However, the methodology and considerations outlined are applicable to a wide variety of regions, rate schedules, crops, and soil type situations.
