The Community Systems Program is concerned with conserving energy and scarce fuels through new methods of satisfying the energy needs of American communities. These programs are designed to develop innovative ways of combining current, emerging, and advanced technologies into Integrated Community Energy Systems (ICES) that could furnish any, or all, of the energy-using services of a community. The key goals of the Community System Program then, are to identify, evaluate, develop, demonstrate, and deploy energy systems and community designs that will optimally meet the needs of various communities. Integrated systems offer considerable potential for fuel substitution, thereby allowing the use of non-scarce fuel resources that would not be economically usable in smaller unintegrated systems. Input energy sources for such systems may include low-grade waste heat, solid and liquid wastes, solar and geothermal heat, seawater heat dissipation, and use of less-scarce fuels, such as coal and biomass. A Grid-Connected ICES uses a central co-generation plant and distribution system to provide heating, cooling, and electrical energy services. During 1977, contracts for the following Grid-Connected ICES (G-C ICES) demonstration teams were negotiated: City of Independence, Missouri; Clark University; City of Trenton, New Jersey; Health Education Authority of Louisiana (HEAL); and University of Minnesota. …
