SECTION 2: METHODOLOGY USED TO CALCULATE PROJECT SAVINGS <br />The mctliodology used for projecting savings resulting from the implementation of the proposed project is <br />summarized in the followvtg equation: <br />Annual Satins = E'rieW Savings + Operational Savings <br />Operational Savings = Operational & Maintenance Savings (O &M) + <br />Capital Cost Avoidance <br />VItc•re: <br />Annual Savings: 'Ilic total animal savings associated with implementation of this project. This is the <br />savings figure (lilt will be used for comparison to the Guaranteed Sayings <br />as part of the Guarantee Reconciliation, <br />Fnetgy Savings: 77e. total 1>nergy Savings associated with reduction in crier@- consumption as a result <br />of implementation of this project. <br />Operational and Alainte.nance Savings (O &M): The total Operational and \laintenancc <br />Savings (0& : \7) savings associated with reduction in operations, <br />mainrenance and repair related expenses as a result of implementation of <br />this project. <br />Capital Cost Avoidaoee: '11iis is defined as future capital expenditures (outlay) that the Customer should <br />have budgeted over a certain period of tine to eventually replace the <br />cystern / equipment / etc. that arc included in the Scope of Services. This <br />is an annualized value and is also referred to as avoided capital. The EC \Is <br />included in the Scope of Services have been analyzed and the future capital <br />replacement expenditures that would otherwise be associated with each <br />ECU have been estimated and reviewed / discussed with the Customer. <br />1IVAC Calculations — arc derived from Pan and Pump Laws and are documented in: <br />a.
