... The study involved three basic steps: o identification and quantification of thermal loads on an areawide basis o identification and characterization of existing and potential thermal supply sources o configuration and evaluation of early-start district heating projects based on spatial location and distribution of thermal loads and thermal sources.

... Table D-2 summarizes the data and results of the fuel equivalent net revenue analysis for the Cherry Hill district heating system, supplied from the municipal solid waste incinerator. As indicated, projected system revenues fall short of operating expenses during the first three years, indicating a net loss before taxes.
