This project assessed how a combination of time-of-use water meters and information affected consumption patterns for representative members of customer classes during peak summer electricity demand periods. The project also assessed the resultant change in water agency electrical demands. Compared with the control group, residential intervention customers reduced their peak period water use by more than 50% (significant at the 0.05 level) and their total use by an average of 17% during the study. These reductions in peak and total water use for this group persisted after the study was completed. Business and irrigation groups did not demonstrate statistically significant water consumption changes. The project also determined the water embedded energy of the water agency and the effect of reducing on-peak water deliveries on system electricity consumption. Results of this study demonstrated that changes in customer consumption patterns may represent a viable electricity demand response opportunity and cost reduction mechanism for the utility.
