Further discussion included the reality of the Minnesota latitude for a 10 KW system and degree of slope to address sun angels, shorter winter days, and degree of slope for the panels and even without snow, wintertime production averages only 10% of the annual production, with most production and annual power during the summer months. Mr. Kroll reviewed the latest iteration of the Power Purchase Agreement (PPA) and highlighted the changes made since their firm's last presentation to the PWETC, including PV production based on current Xcel Energy rates the city was receiving for the skating center; the PPA rate and cash flow; and different investor proposal than originally presented and rationale in recommending this investor. Mr. Kroll noted that the original intent was to install an east/west array based on size versus production available on the skating center roof until further research was done on the complex rate structure with Xcel Energy for the OVAL and skating center. Mr. Kroll anticipated this PPA would benefit economics for more production and face completely sough and maximize KWh versus pursuing the solar credit benefits, and would be a 300 KWh array versus the original specifications planned for a 375 KWh system, even though he predicted the economics realized will be equal to or greater than those original projections by going to standby service recognizing solar credits and their value in this model, especially with the OVAL and its interesting usage curve. Mr. Kroll advised that he still needed to further vet out the OVAL and capacity schedule with Xcel Energy and reconciliation of those credits by blending rates. Mr. Kroll reviewed anticipated annual generated revenue and cash flow, still pending finalization. At the request of Mr. Culver, Mr. Kroll reviewed the PPA and how the money changed hands, what the city could anticipate and the amount paid to the developer and by whom. Mr. Kroll advised that the city would be charged for usage to -date, then receive production credits against those KWh for the production portion of the system not being charged for, as a separate line item showing the credit attained from the KWh level, and another line item showing the capacity credit received from the percentage of solar capacity credits, or what the city was paying for the solar PPA and extra monies as their reconciliation. At the request of Mr. Culver, Mr. Kroll reviewed how the city would get invoiced, pending the negotiated PPA, from Xcel invoices based on monitoring and production and supplemental invoice from the investor and differentials between the two. Additional discussion included some months with no credit and others with a huge credit, with annual reconciliation based on that monthly ebb and flow, some of Page 6 of 18
