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.
