Overview of Solar Development
• Identify Target Site
• Determine Site Suitability– Site Orientation
– Potential Shading
– Location relative to load/distribution system
• Site Owner Outreach– Self Generation/Lease/Own?
• Determine Interconnection Requirements
• Market Project– Net Meter
– PPA to Utility (or “Buy all/Sell all”)
– Community Solar

Engineering & Environmental
• Field Work
– Phase I
– Fatal Flaw Analysis
– Wetland delineation
– ALTA survey
• Engineering
– Preliminary Site Plan
– Grading Analysis
– Geotech
• Borings or Pull-Test

Resource AssessmentsData Sources
• Very different from wind projects!
• Smaller sites, production driven mostly by clouds and latitude.
• Public solar maps, datasets produced by NREL are sufficient.
– Some large projects use met towers, but they are smaller (~8 feet tall) and cheaper.
• Banks may begin to require on-site data as size of investment (and associated level of risk increases.

* Alliant/Interstate recently announced the sale of its Minnesota electric systems and customers to a consortium of Southern Minnesota
cooperatives. If the sale is approved, these customers may become exempt from the solar energy standard
** Assuming a 15% solar capacity factor
From Docket E-999/CI-13-542
Aurora Solar Project
• 100 MW Distributed Solar Project– 22 separate sites
– Each site between 2-10 MW
– Interconnected to Xcel Energy distribution substations
• Proposed in Xcel Energy’s Capacity Acquisition Process– Only renewable project in the process
– Competing with several natural gas generators
– PUC decision expected Feb-Mar 2014
• Will provide capacity resource and help meet Xcel Energy’s Solar Energy Standard
