Water Heater Modeling Load Research Study

For the Electric Power Research Institute (EPRI), a member of the Firm participated in a detailed study to model the energy use of residential water heaters as part of an EPRI research project. Working with a consultant team that included Associated Edison Illuminating Companies (AEIC) Load Research Committee members from several large utilities, the project encompassed the development of a physical model as well as a model of the customer use characteristics. Multiple sites were selected, and variations on the equipment, installation specifics, and configuration of the dwellings were tested and incorporated in the physical model. Hourly data collected from interval metering was processed with demographic data to model the customer use characteristics in conjunction with the physical model.
