This study presents a cost minimizing optimization formulation to model the electricity consumption behavior of the University of California, Davis chilled water plant. Annually, this chilled water plant consumes 25 GWh of electricity and produces 36 million ton-hours of cooling capacity. The chilled water plant also contains a 5-million-gallon thermal energy storage tank that offers operational flexibility. The cost minimization program considers chilled water system operating constraints, campus chilled water demand, day-ahead electricity market rates, and the CAISO's Proxy Demand Response (PDR) program.Electricity demand was simulated for the 2019 year under two optimization scenarios (1) cost minimization including PDR participation and (2) cost minimization not including PDR participation. The results show that the PDR Program has the potential to save UC Davis $110,000 annually on operating costs for its central chilled water plant. This is in addition to $797,000 in annual cost savings that would occur if the University were to minimize operating costs considering only daily fluctuations in electricity market prices. Review of the University's PDR bidding and event hour activity reveals that much of this extra benefit to the University is earned through miscalculations in the administratively set baseline. Analysis of PDR bids shows that demand response participation is not significantly influenced by fluctuating electricity rates. Meanwhile, a comparison of the two modeled scenarios shows that day-to-day electricity consumption patterns differ between PDR participation and non-PDR participation models but, on average, there are no significant changes in load profile resulting from PDR participation.
