Twin Cities Potential Sites St PaulUMore ParkMinneapolis

Twin Cities Site Assessment ❏ Best Potential Sites: ❏ UMore Park ❏ Carlson School ❏ University Ramps ❏ Site Criteria ❏ LiDAR Data ❏ Roof Condition ❏ Electrical Interconnection ❏ Structural Analysis ❏ Cost ❏ Historical Preservation

Twin Cities, MN Site Assessment Team ❏ Lidar Based Site Assessment ❏ Total Insolation Inventory ❏ Roof and Parking Files -with structural data

Duluth, MN Site Assessment Team ❏ Identifying list of potential UMD campus solar sites/projects ❏ Expanding Malosky Stadium Array ❏ Natural Resources Research Institute Roof ❏ Assembling Resources ❏ Gathering faculty advisor support ❏ Working to collect mapping resources ❏ Obtained building data from UMD Geospatial Analysis Center ❏ Partnership with Ecolibrioum3 for help with solar suitability mapping

Community Solar Garden ❏ What is a Community Solar Garden? ❏ A developer owns a PV array and sells the electricity to subscribers. ❏ Why is it beneficial to the University of Minnesota? ❏ lower risk for the University ❏ Don’t have to worry about maintenance ❏ get billed for energy consumption

Community Solar Garden 3 Ways to Participate in CSG ❏ Lease property to a developer: ❏ Pay for space, and buy electricity from the developer. ❏ Develop own CSG: ❏ Control over project, but much more cost and risk. ❏ Purchase power from a CSG: ❏ Pay utility bill to developer that owns the site.

Outreach ❏ MN is a national leader on renewable energy ❏ Outreach campaign to move decision makers ❏ Develop messaging around solar ❏ Website for publicity, petition collection ❏ Get articles in campus, local media ❏ Run campaign to get alumni, student, staff support
