Roseville Public Works, Environment and Transportation Commission Agenda Item Date: August 28, 2018 Item No: 5 Item Description: Review of Community Solar Garden Subscription and On Campus Solar Options Background: At their July meeting, the PWET Commission received a presentation from iDeal Energies about their proposal for on campus solar installations on various buildings on the Civic Campus. We will review those proposals and ask the Commission for a recommendation to bring to Council likely on September 10"'. 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. The City would sign a Power Purchase Agreement (PPA) with iDeal 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. Attached is updated information on the proposed financing and power purchase agreements for the proposed installations. At this time, given the timing for the roof replacement on the skating center, we are only looking at City Hall, the Fire Station, and the newer roof portion of the Maintenance Facility. The City Hall option would include a ground mount Solar Rewards system installed on the slope between City Hall and County Road C. Staff will also review the Community Solar Garden Subscription Agreement Council authorized at their August 13"' meeting. The information presented to Council with details on the Subscription Agreement is attached as Attachment A.
