Roseville Public Works, Environment and Transportation Commission Agenda Item Date: July 24, 2018 Item Description: City Campus Solar Installation Proposals Background: Item No: 7 Staff has been working with iDeal Energies on different proposals for rooftop and ground mount Solar PV installations. Currently we have layouts and economics for City Hall, Public Works, Fire Hall, and Skate Center that incorporates rooftop solar. The ground mount installation is proposed to be on the slope between City Hall and County Rd C, with the actual location and layout to be determined. The rooftop installations are shown to maximize savings given our usable space and building energy consumption. The economics included in the proposals show the revenue and costs associated with the arrays over a 40 year timeframe, with a buyout option at year 18. Meal Energies provided other buyout scenarios for review, and staff included the 10 year option as an example. The City would sign a Power Purchase Agreement (PPA) with Meal Energies for the solar arrays. There would be no cash required upfront, and all operations and maintenance would be fulfilled under the PPA by the financer/developer. After the City exercised the buyout option, then the City would receive all the energy produced and would assume operation and maintenance. The ground mount system is shown as an Xcel Energy Solar Rewards. The Solar Rewards provides incentives to customers who install grid connected arrays. Xcel would purchase the power at a predetermined value, and would include a future escalator. The City has the option to purchase the system at year 13. The Solar Rewards option could be applied to any rooftop option, with a maximum array size of 40kW. Included with the attachments is a review of the City's previous efforts to install Solar on Campus, as it was presented to the City Council earlier this year.
