16. Installation of a Solar Energy Project at the Operations Services Center <br />Director of Operations Services Daniel Smith presented the staff report, stating that in line with <br />the Council's priorities for energy efficiency and environmental programs, staff retained energy <br />consultant, Energy Solutions, to explore the feasibility of photovoltaic (PV) systems at all City <br />facilities. An analysis of existing structural conditions, shading, and electrical systems has <br />resulted in a design for PV panels on Municipal Well 8 and several of the Operations Services <br />Center's (OSC) main buildings. Staff believes that this design best combines environmental <br />protection efforts with cost return for the city. <br />The proposed system would generate 80 kilowatts of DC power for OSC and 275 kilowatts for <br />Well 8. Mr. Smith explained that the system designed for Well 8 is much larger because its <br />meter rate and usage schedule results in a much higher charge than that of the other buildings. <br />The electrical generation of the system is expected to produce about 20% of the electricity used <br />at OSC and 55% of that at Well 8, for a combined production total of 40% of the entire facility's <br />electricity. Carbon emissions would also be reduced by 248 tons with this system. <br />The total system is expected to cost $2.5 million including parts, labor, installation, permitting <br />fees, maintenance, and inverter replacement at the 13 year mark. While state and federal tax <br />incentives like credits and accumulated depreciation cannot be taken unless a third party or <br />private enterprise is used, there is limited potential for kilowatt-hour buyback and sale of <br />renewable energy credits. The greatest incentive is available through the California Energy <br />Commission -California Solar Initiative (CSI) which is a performance based incentive that pays <br />a set amount per kilowatt-hour produced during the first five years of installation. <br />Mr. Smith noted that numbers have changed somewhat as the incentive dropped a tier during <br />this analysis and resulted in a $173,000 decrease to the amounts projected. The cost of a CSI <br />reservation for the recommended system is $10,000, which would lock in the current rate for up <br />to one year while an RFP is obtained and the project is implemented. <br />Mr. Smith outlined the four financing options for the system: <br />• Lease - A third party assumes the upfront purchase and installation costs, receives the <br />tax benefits, collects a monthly lease, and at the end of the lease offers the City a <br />purchase option at the current market rate. <br />PPA - A Power Purchase Agreement with a third party that assumes a fixed rate paid <br />per kilowatt-hour over the 20 years of the agreement. While electricity costs can fall on <br />either side of current rates, the advantage is the lack of capital, operation, and <br />maintenance costs. <br />• Low-interest Loan- Is not viable without private party incentives. <br />• Outright purchase - Is viable as Well 8 would provide a high return and enterprise funds <br />could be used for that portion of the installation. <br />Staff recommends that the Council authorize issuance of an RFP for solar installation that would <br />allow contractors to bid on the following project types: PPA, lease, or outright purchase. Staff <br />also recommends that the Council authorize the City Manager to pay the CSI reservation fee. <br />Councilmember Thorne asked if the CSI reservation fee is later applied to the project or <br />assumed by the initiative. Mr. Smith said that the funds are only forfeited if the City chooses not <br />to complete the project. <br />City Council Minutes Page 12 of 17 April 7, 2009 <br />
