Individuals with demonstrable experience,appropriate to the type of Study being performed must be responsible for conducting the Study. 3. The Engineering firm performing this Study must do so with impartiality towards equipment suppliers,distributors,and all equipment or product brand names. 4. The Study must be performed according to the Study Workscope Section of this application. 5. Xcel Energy makes no warranties regarding the Study.All such warranties are between the Engineering Firm and the Customer.Rebate qualifica- tions do not imply any representation or warranty of the Study by Xcel Energy. 6. Xcel Energy's decision relating to customer eligibility for the Study or other issues will be final and binding for all parties. 7. The Customer shall be responsible for directing the work of the consultant or the contractor;at no time shall the consultant or contractor be con- sidered an agent,employee,or a contractor of Xcel Energy. 8. The Xcel Energy Funding Authorization section of this application must be signed prior to initiation of the Study. 9. The Study must be completed within three(3)months of the Xcel Energy Funding Authorization Date. 10.Xcel Energy reserves the right to perform pre-and post-installation energy testing and data collection. 11.Xcel Energy reserves the right to accept or reject any application,Study,or portion thereof. 12.Xcel Energy will pay study rebate upon customer payment of study to engineering firm. Requirements:The purpose of the Study is to provide a customer with the necessary business case justification to implement the energy-saving opportunity.All studies should include the information listed in the business case justification and the program requirements section. A.Executive summary Report will include an Energy Conservation Opportunities form briefly describing the purpose of the Study,existing conditions,and options considered. B.Introduction In addition,the report will contain an introduction section consisting of customer information and an Xcel Energy(Company)disclaimer. C.Study summary A Professional Engineer will fill out the Energy Conseroation Opportunities(ECO)form(i.e.material and/or format provided by Company)of capital costs,incentives,energy reduction/increase in kilowatts,and reduction/increase in natural gas MCF,reduction/increase in district cooling energy use,reduction/increase in other fuels/utilities. , D.Project description The following will be provided for retrofit opportunities: •Description of existing equipment,including sketches,drawings,flow diagrams,photos as necessary to explain and describe the project;and •Explanation of how the proposed project will modify the plant process or building. The following will be provided for equipment upgrade situations: •Description of the proposed energy alternative�s)and the comparable"standard"or"normal"alternative; •Description of plant upgrade and how the different energy alternatives will affect operation and function; •Description,sketches,drawings or flow diagrams as necessary to explain and describe the energy use relative to the"standard'alternatives. E.Energy estimate The following energy-use calculations and calculated estimates will be provided with regard to the project scope of work: • A calculated estimate of annual electric energy use in kWh,month�y maximum demand in kW and/or natural gas MCF.This calculation will include an indication of when,during the day and year,the demand and energy consumption will occur. • A calculated estimate of annual electricity/natural gas reductions/increases in use and cost,based on the rate Schedule most appropriate for the customer.Request rate information from the customer's Company account manager. • Indication of how estimate data was derived(e.g.,theoretical calculations,field measurements,manufacturer's data,etc.) • An estimate of the project cost and payback period. • A description of the proposed modifications to improve energy efficiency. F.Measurement of energy The Study will include a plan to verify the electric energy use(e.g.,after the project is implemented how will the building owner or plant manager know that the project is using/reducing the energy estimated►.Costs associated with verification must be identified. G.Non-energy project impacts • The Study will estimate other quantifiable benefits and costs to implement the potential energy project,such as impact on production or building function levels,operating and maintenance costs,and plant reliability.Positive and negative impacts will be considered. • The Study also will provide an indication of project impacts that may be difficult to quantify,such as safety and environmental considerations and product quality. p.3 of 4 09-06-537 O6/2009
