Solar Energy Potential for Idaho State Endowment Trust Lands Capstone Project Master of Geographic Information Systems Pennsylvania State University (PSU) Kimberly Pettit Advisor Dr. Pat Kennelly Outline • • • • • • Why Investigate Solar? Project Overview Types of Solar Energy Evaluation Criteria Example Project Trust Land Results Why Investigate Solar? Image courtesy of Idaho Department of Lands Strategic Business Unit (2010) Project Objective • Determine “suitable sites” for solar development on Idaho’s state endowment trust lands Deliverables • Suitable sites map • ArcReader document • Geodatabase • Parcel list of trust lands rank > 4. • Land rankings excluding specific criteria including: – Asset Class – Distance to Transmission/Transportation – Wilderness Uses and Applications • Decision support for IDL regarding future solar development on trust lands. • Supports Idaho’s legislative resolution for developing renewable energy. • Renewable energy development cooperation with other states’ programs.
