Generation System Impacts of Storage Heating and Storage Water Heating

Thermal energy stroge systems offer the electric utility a means to change customer energy use patterns. At present, however, the costs and benefits to both the customers and utility are uncertain. As part of a nationwide demonstration program Public Service Electric and Gas Company (PSE&G) installed storage space heating and water heating appliances in residential homes. Both the test homes and similar homes using conventional space and water heating appliances were monitored, allowing for detailed comparisons between the two systems. The purpose of the paper is to detail the methodology used and the results of studies completed on the generation system impacts of storage space and water heating systems. The paper is organized into three main sections. The first gives background data on PSE&G´s load management philosophy, assessment methodology, and experience in a nationwide thermal storage demonstration project. The second section details results of the demonstration project and studies that have been performed on the impacts of thermal storage equipment. The last section reports on the conclusions arrived at concerning the impacts of thermal storage on generation.
