BOWEN GUARANTEE MANAGEMENT <br />7e) Note how an Operations & Maintenance estimate will be prepared and <br />applied to the project. <br />Bowen estimates operational and maintenance savings that show actual expenditures from the municipal <br />utility's assets that are being replaced as part of the guaranteed savings project. By replacing assets that have <br />experienced numerous repairs over the years, the utility will reduce maintenance costs and can use those <br />savings as a source to justify the project. <br />70 Note how a Future Capital Expenditure Savings estimate will be prepared and applied to <br />the process. <br />Per the statute, we use Industry Engineering Standards, in most cases RS means estimating and <br />historical data. For each component in the system that is being replaced, the annual savings value is <br />calculated. The total of all of these components is the cost avoidance for the conservation measure. <br />Bowen will apply this method to preparing a future related capital expenditure savings estimate. <br />Pictures and One Operational Savings Calculation Below Are From The <br />City of West Lafayette DeHart CSO Storage Tank/Tunnel GSC Project <br />West Lafayette, IN Energy Conservation Measure: The Dehart project will <br />save the City Emergency Response time and <br />Maintenanoa time due to Overflow events <br />A—mptions: vuerfl-7ntswereaoeraged tocome up with 001 <br />$20/hr. cost per man hour <br />1 h r. ti me al lotment was—u med fora regular mai ntenance wl I <br />Rggu lar mai ntenance cal Is are made (3l t imes per year <br />1/2 h r. t I me al lot ment was amu med for an emergency cal I <br />Man Hours <br />Annual Stop page Cost per man <br />ID Tri s Time hr hour Annual Cost <br />Emergency r 30 0.5 $ 20.00 $ 300.00 <br />Maintenance 3 1 $ 20.00 S fi0.00 <br />COSTSAVIN65= $ 360.00 <br />.Variahilify= 9035 <br />GUARANTEED ANNUAL SAVINGS = $ 324 <br />
