End-use load data analysis is assuming a growing role for utility demand-side planners around the country. This paper describes the results of implementing several transferable analysis tools for the analysis and evaluation of end-use monitoring, direct load control programs. These tools are the Duty Cycle Model and the Demand-Side Design and Analysis Workstation. The PC-based Workstation has proven itself to be a viable, cost-effective means of analyzing the voluminous data used in the program evaluation. Unlike other program evaluation techniques, the Duty Cycle Model can calculate the load impact of virtually any load control strategy, not just those operated by the utility. Using air conditioner (AC) data from the Athens (Tennessee) Automation and Control Experiment, the authors calculated that average peak period AC load reduction was 0.92 kW under a 40% cycling strategy.
