Assumptions related to increased efficiency of supporting operations assumed a reduction in frontend annual operating expenses from 7.5% to 2.5% of total capital expenses. Assumptions related the sludge pasteurization service, such as lower sludge moisture content, higher biogas combustion efficiency, LPG as fuel source for pasteurization, and single sludge pasteurization unit for one NEWgenerator. The component changes (lithium photovoltaic battery and low-cost housing) each reduced median per capita cost by approximately 0.5 cents, while frontend 2.5% annual O&M (as a percent of total capital costs) decreased it by 0.3 cents; all had no substantive impact on GHG emissions (Figures and). Typical sludge moisture contents from additional drying (e.g., mechanical processes, drying beds etc. without additional equipment accounted for) prior to the pasteurization unit was considered to reduce the moisture content from 93
