<br /> <br />22 <br />5.3.2. OPERATING COSTS <br />Operating costs consist of electricity consumption for water-source heat pump and VRF system, pumps, and <br />well pumps. Additionally, the district energy system requires a management and maintenance allowance. <br />Capital costs are not included in the operational costs. <br />In 2030, the first year of full buildout, the estimated operational cost under a business-as-usual scenario is <br />$2.6 million. Scenarios 1, 2, and 3 have estimated cost savings of $0.7 million, $0.8 million, and $1 million, <br />respectively, compared to business as usual, as summarized in Table 8. This results in an estimated <br />operational cost savings ranging from 27% to 38% depending on the scenario. <br /> <br />Scenario 1: <br />District <br />Energy - <br />Entire <br />Development <br />Scenario 2: <br />District <br />Energy - <br />Town <br />Center <br />Scenario 3: <br />Decentralized <br />Geothermal <br />Green Energy Operational Cost (MM$) $1.9 $1.8 $1.6 <br />Operational Cost Savings (MM$) $0.7 $0.8 $1.0 <br />Operational Cost Savings % 27% 31% 38% <br />Table 8. Estimated operational costs in the year 2030. <br />The 2030 operational cost trend continues throughout the 30-year life-cycle cost analysis. A comparison of <br />the cumulative operational costs from 2027 to 2050 is illustrated in Figure 11.
