8.D. - Page 15 <br /> participation in the audit and retrofit programs for municipal facilities that are funded by state, <br /> regional, county and utility programs. It further recommends targeting half the existing facilities <br /> for audits and implementation of energy savings projects by 2020 with 15 percent energy <br /> savings overall. Depending on staff time and resources, this Plan also recommends exploring <br /> using energy service companies for additional audit and retrofit opportunities beyond the <br /> publicly funded programs. <br /> Unfortunately, rising electricity costs can cut into the dollar savings from implementing energy <br /> efficiency projects in municipal facilities. Figures 1 and 2 show that the 15 percent energy <br /> savings target could represent as much as a $59,793 reduction in annual electricity costs over <br /> 2010, assuming the price of electricity remains the same as in 2010, but it would result in a <br /> $37,926 increase from the City's 2005 electricity cost due to an almost 20% increase in <br /> electricity costs from 2005 to 2010. If electricity costs do continue to rise, or if new buildings are <br /> added to the municipal portfolio, implementing efficiency projects becomes an effective cost <br /> control measure for the City. <br /> Figure 1: Municipal Facilities Electricity Use (kWh) with 2020 project estimate <br /> 5,400,000 <br /> � 5,200,000 5,194,730 <br /> � kWh <br /> � 5,000,000 <br /> v 4,800,000 <br /> � <br /> T 4,600,000 4,744,86 <br /> +� kWh <br /> ;� 4,400,000 <br /> � 4,200,000 4,388,999 <br /> v kWh <br /> "' 4,000,000 <br /> ' 3,800,000 <br /> 2005 2010 2015 2020 <br /> Year <br /> Figure 2: Municipal Facilities Electricity Cost ($) with 2020 project estimate <br /> $s2o,000 <br /> $800,000 $797.Z44 <br /> � $780,000 <br /> o $760,000 <br /> T $740,000 $737,451 <br /> � $720,000 <br /> � $700,000 $699,525 <br /> W $680,000 <br /> $660,000 <br /> $640,000 <br /> 2005 2010 2015 2020 <br /> Year <br /> 6 <br />
