Performance <br />Services <br />prui <br />this to be a critical value -add service for cities and Boards so that there is clarity and transparency on <br />how the project has performed and the realized financial benefits. <br />Performance Services can administer the Energy Savings Guarantee on solar projects by performing <br />system output measurements at given weather conditions to prove the system is performing as <br />anticipated. If the system does not produce the power output as expected, per industry standard <br />calculations, Performance Services will modify and/or rectify the system to meet the Guaranteed <br />output. <br />utility <br />Guaranteed Savings are savings in energy due to reduced usage. For your project, the energy created by <br />the solar system would be guaranteed. These utility savings will be directly available to the Owner for <br />use to repay the financing. As with almost all of our solar installations, we expect the city of South Bend <br />will go with the stipulated method. With that, we would recommend Option A that involves a one-time <br />measurement of solar output. However, this is up for discussion, and PSI will follow your lead on which <br />method you would like to use. <br />O&M <br />Performance Services does not require a service contract for maintenance. We have a standard <br />warranty and do not believe that a solar system needs the expense of a service contract to generate <br />savings. Performance Services will provide training on monitoring and maintenance practices to help <br />manage the systems after our warranty to limit your annual 0&M costs. Lastly, if building energy <br />savings opportunities are also selected as part of this project, there may be some 0&M savings with any <br />new equipment or lighting selected. For example, some customers hire a trade contractor to replace <br />their existing T8 or T12 lights, especially in 2 story areas where a lift is needed to replace the lights. The <br />expense paid to the trade contractor will become $0 and can be claimed as O&M savings if LED lights <br />replace the T8/T12 lights because there will be no replacement expense needed. <br />Capital Cost Avoidance <br />Operational savings exist when an improvement implemented under this program reduces future repair <br />or replacement labor and/or material monies that would have otherwise been expended if the <br />improvement was not implemented. This is not typically shown in solar solutions but more likely in <br />building envelope or HVAC/lighting projects. The amount applied to this is determined and agreed to <br />with the customer upfront for those solutions. <br />These savings would be considered stipulated. <br />Confidential & Proprietary Document 12.
