which would be addressed in the PPA, such as if the city chose a 6 -month <br />annualization payment to avoid more disparity and allow for easier management; <br />and lower wintertime output at highest point of usage and how that impacted the <br />overall cost. <br />As an example of credit reconciliation, Mr. Kroll reviewed advised that the OVAL <br />energy rate was calculated on the size of the system, not how much it produced that <br />would remain the same every month. Mr. Kroll advised that for ten months, the <br />City would receive a credit, and could choose which two months of the year they <br />set as their "demand holiday" to receive a discount on the full demand load. Since <br />the OVAL has very high usage in the winter time, in a traditional scenario, Mr. <br />Kroll suggested the city could strategize to set its demand holiday for the highest <br />usage months to receive money off the entire demand load and establish standby <br />service. However, Mr. Kroll advised he was still checking with Xcel Energy to <br />determine their flexibility with that and to make sure the reality of that option would <br />actually play out, with more research to be completed on his part to finalize <br />numbers as accurately as possible. <br />At the request of Member Seigler, Mr. Kroll responded that if the solar system <br />produced more energy than it consumed, it would be sold on the grid and metered <br />accordingly. However, Mr. Kroll opined it would be unlikely that the city would <br />ever reach that limitation for receiving a credit back. Mr. Kroll advised that their <br />design engineers were conscious of the need to design it based on constraints of the <br />demand charges and usage to best maximize what the city received and use the rest <br />for the arena. Mr. Kroll noted that the arena used way more energy than balanced <br />on the system, but the goal was to maximize the overall profitability of the system <br />between the two meters as much as possible and utilize the available space on the <br />roof. Mr. Kroll noted that the size and design of the system would allow more <br />detailed finalized numbers to determine performance curves and profitability as <br />would be detailed on the PPA schedules. <br />Further discussion ensued on the purchase options in this scenario; how the actual <br />formula and credits were determined; language of the standby tariff as written and <br />requirements for Xcel Energy to at a minimum allow the city with a limited amount <br />of credits on a certain percentage of KWh or negotiated limitation on the system <br />size to demand profile depending on how Mr. Kroll was able to vet that out with <br />Xcel before finalizing the PPA for review and consideration by the PWETC and <br />City Council. <br />Mr. Kroll advised that the next step was 1) to receive the go-ahead from the city for <br />the project; and 2) for lawyers on both sides to review contract language of the PPA <br />after which they could begin the design process of working with Xcel Energy to <br />design the system for the city to compare with cash flows prior to signing the <br />contracts. Once signed, Mr. Kroll advised that their firm would then begin the <br />actual engineering specifications available for the system. Due to the expense of <br />the engineering and design process, Mr. Kroll noted that that work was done after <br />contracts were signed. <br />Page 7 of 18 <br />
